Frequently Asked Questions

The production purpose (branding/database collection/commerce), target audience, list of essential features, benchmarking sites (3–5), approximate budget, and desired launch date.

Yes, you must prepare at least one or two pages so that companies can calculate quotes based on the same standards, preventing inflated prices or omissions.

You must convey not only the overall impression but also specific elements separately, such as the 'menu structure of Site A,' 'quote calculation function of Site B,' and 'tone and manner of Site C.'

Cross Design organizes the initial main and sub-menu structure, and the client organizes it to align with the essence of the business, while the final UX flow is refined in consultation with the Cross Design Group.

Basically, text manuscripts and logos/product photos are provided by the client; however, for hospitals, Cross Design Group possesses well-planned content for medical departments accumulated over 14 years (until August 2026). If copywriting, professional photography, or paid stock images are required, additional costs must be reflected after prior consultation. Regarding photography, our superior AI technology allows us to provide support at a cost that is currently trending low.

It is possible, but since it sets the standard for the site's tone and manner, you must decide in advance whether to use a temporary text logo or commission a logo design as well.

While it is common for the client to provide the translation, cross-design is possible, including both Korean-based AI translation and original language translation. Please confirm whether translation data input and correction for UI glitches specific to each language are included in the quote.

Template-based landing pages take 1–2 weeks, general corporate promotional types take 4–8 weeks, and customized hospitals, functional/shopping malls, and platforms take 2–4 months or more.

We create together. Design and development begin during the planning phase. Finalizing the plan at the wireframe (screen design) stage prevents future rework and additional costs.

Cross Design Group is a manufacturer with 15 years of know-how in responsive design (PC, TABLE, MOBILE).

You need to check the scope of data migration (members, posts) from the existing site and whether to handle URL redirects to maintain existing SEO (search rankings).

Due to legal liability issues, client companies must conduct their own legal reviews or provide customized government standard terms and conditions.

While it is a legal obligation for public institutions and large corporations, general companies only comply with essential elements (such as image alt tags), and obtaining certification marks incurs separate costs.

Support for the latest versions of Chrome, Safari, and Edge is standard; if special environments (such as older browsers) are required, this must be specified during the planning phase.

It is smoother if you select a vendor that focuses on screen flow (wireframes) rather than technical jargon during planning meetings and assigns a dedicated PM (Project Manager).

This is due to the use of no-code/templates, the use of purely custom coding, and the difference in M/M (in-month) unit costs for the personnel involved (planners, designers, publishers, developers).

Template-based options range from 50 to 150 million won, while high-conversion landing pages featuring professional copywriting and customized interactions cost around 200 million to 300 million won.

Template-based services range from 150 million to 300 million won, while custom design/publishing ranges from 350 million to 800 million won.

Basic shopping malls integrated with PG companies range from 3 million to 8 million won, while platforms with complex functions (recurring payments, partner malls, matching, etc.) can be expanded from 15 million to 100 million won.

Standard payment is made in installments: a down payment (30–50%), an interim payment (30–40%), and a final payment (10–20%, after inspection).

For customized SI projects, you may request a detailed breakdown of manpower input and man-hours (M/D, M/M) based on software technician labor rates.

There are domain costs (2 to 3 won per year), web hosting/cloud server fees (1 to several hundred thousand won per month), SSL certificates (10 won per year), and solution subscription fees. Basic website operation costs 12 to 24 won per year (including hacking prevention, free recovery in case of hacking (worth 20 won), traffic downtime, search updates, and system stabilization management).

There are risks such as the copying of low-quality factory-made templates, failure to transfer ownership, mandatory agreements on excessive monthly management fees, and excessive additional charges for added features.

This occurs when adding new pages or features, or completely revising the layout, during the design/development phase after planning is complete.

You must check whether 'VAT excluded' is indicated at the bottom of the quotation, and verify whether an additional 10% is charged when issuing an electronic tax invoice.

These are separate. Payment gateway (PG) registration fees (approximately 20 KRW, free during promotions) and card transaction fees are contracted directly with the PG company.

You must verify whether the company uses commercially available genuine fonts and paid stock images, and whether there are any additional costs for using them in marketing materials other than the website after delivery. Cross Design holds licenses for both social media and print use. Separate arrangements are required for overseas production.

You must verify the supplier registration status, the availability of support for completing the designated deliverable form for the support project, and the self-payment ratio for VAT.

Providing two main drafts is often standard, and Cross Design proceeds through thorough design planning consultations to ensure that hasty drafts are not produced. If redoing is required, it is Cross Design's responsibility. Additional costs may apply if you wish to compare multiple drafts (3 to 4 types).

If the number of free revisions for each stage (planning/design/development) is exceeded (usually 2 to 3 times), additional charges will be applied based on the hourly labor rate (unit price).

Pros: Powerful scalability, 36% global market share as of March 2026, plugin ecosystem, excellent SEO. Cons: Potential for plugin conflicts, need for periodic security updates, difficulty of management. Cross Design Group has possessed the technical capability to produce and supply various bulletin boards using the expertise of a WordPress developer since 2012, and holds stable and leading WordPress technology.

Pros: Rapid development, intuitive admin page, low maintenance costs. Cons: Limitations in implementing complex custom features, inability to migrate source code to other servers.

It is suitable for sites primarily focused on product sales, as it integrates Korean-style e-commerce features such as domestic payment, delivery tracking, settlement, and coupons.

It is essential for platform services requiring unique business logic, large-scale traffic handling, mobile app integration, and specialized algorithms.

Rental-type builders are not available, and for standalone/custom development, you must specify a clause in the contract stating 'provision of all source code and deliverables' to receive them in full.

For general corporate promotional purposes, cost-effective web hosting or Cafe24 hosting is sufficient, while AWS or GCP is suitable for services with significant traffic fluctuations or those requiring scalability.

You can release a hybrid app by wrapping a mobile web application, but this requires additional development effort for push notifications, App Store reviews, and integration with native features.

Routine operational functions, such as replacing text and images, managing bulletin boards, configuring popups, and checking form data, must be implemented so that they can be performed directly from the administrator screen.

For general websites, a monolithic (integrated) design is cost-effective, but separate development is recommended when there are clear plans for future mobile apps or multi-platform integration.

You must include image compression (WebP conversion), code lightweighting, and CDN application in the development requirements in advance.

Installing an SSL certificate and basic security coding are mandatory, but DDoS protection and advanced WAF firewalls incur separate costs depending on the hosting/cloud configuration.

You must use open source that does not conflict with commercial licenses, and you must check a disclaimer regarding license violations in the contract.

For maintenance purposes, it is safe to specify a general-purpose language such as PHP, Java, Python, or JavaScript that is popular and easy for other developers to maintain in the future.

We primarily use standard relational databases (MySQL, PostgreSQL), and use NoSQL in parallel when unstructured data or large-scale logs are required.

For custom development projects, you must verify whether GitHub/GitLab repository permissions have been granted and whether an automated deployment environment has been set up.

Review screen-by-screen interactions by receiving them in the form of Figma, Adobe XD Link, or high-resolution images (PNG/PDF).

The process proceeds in the order of finalizing the main draft → finalizing the subpage template → commencing coding (publishing) after final design approval. Any design changes after approval will incur additional costs.

It is applicable if you possess web font format (WOFF, WOFF2) files and a commercial license for website integration.

While visual immersion is enhanced, excessive use slows down mobile loading speeds and impairs user readability, so an appropriate balance is required.

Of course. The design of the browser tab icon (favicon), the thumbnail (OG Tag) that appears when sharing a KakaoTalk/SNS link, and the company logo are included in the quote.

Since two color palettes and CSS branching for light/dark mode are required, typically 20~30% or more of design/publishing effort is added.

For services with a large number of mobile users (B2C, commerce), the approach is to design first based on the mobile screen and then expand to PC.

Web UI design and content graphic design (event banners, product detail pages) are separate tasks, so the scope of the quote must be distinguished.

It is possible. Additional technical expertise is required for the creation of 3D modeling files (GLTF, etc.) and integration with the Three.js library.

Since it depends on the contract terms, you must specify in the contract whether the 'ownership of original design files (Figma work, etc.)' applies.

The basic scope of services includes meta tags (Title, Description), sitemap (sitemap.xml), robots.txt generation, and registration with Naver Search Advisor and Google Search Console. We are a specialized SEO company.

It is possible. This involves opening developer center accounts for each platform (in the client's name) and issuing API keys for integration. Additional costs apply for Google and Apple.

Linking with notification agency accounts such as BizM, Aligo, and CoolSMS incurs a separate cost per message sent (borne by the client).

Basic tracking code installation is mostly provided, but tracking specific button clicks or conversion events (using GTM) requires prior consultation.

Integration is possible simply by inserting a script; please request installation. It will be reflected easily.

Integration with the free API is possible within the basic call volume, but complex features such as location search and radius search require additional development.

It is possible to develop backend features that instantly render a PDF based on input form data for download or sending to the administrator's email.

Connect the newsletter service's API or embed code to the subscription form on the webpage to automatically synchronize the subscriber database.

Both Naver Reservation integration and the development of a custom reservation calendar (date/time selection, duplicate prevention, payment integration) are possible, depending on the amount of effort required.

You can configure real-time receipt notifications to be sent via the administrator's email or KakaoTalk/SMS.

If the counterpart system provides API specifications, it is possible to develop data synchronization integration (members, orders, inventory, etc.).

You can control popup image registration, link settings, duration specification, and the 'Do not open today' option on the administrator page.

Module integration development is performed after contracting with identity verification agencies such as NICE and KCP, and development costs, annual usage fees, and per-transaction authentication costs are incurred.

It is possible, and the setting of foreign currency payment currencies such as the US dollar (USD) and multilingual support must be considered together.

Insert via a web server/CDN without buffering after YouTube/Vimeo embedding or high-capacity video optimization (MP4/WebM).

These are the scope of work (functional specifications), delivery deadline, payment schedule, revision/inspection standards, warranty period, and copyright and source code ownership clauses.

The contract must explicitly state that all intellectual property rights and ownership are 'transferred to the client' upon full payment of the balance. The ownership and copyright of the development source code belong to Cross Design Group. If the client wishes to directly create derivative works utilizing the source code, this is permitted only after consultation with Cross Design Group.

The domain must be registered under the client's or company name. If registered under a business name, the site may be held hostage in the event of a future change of provider or dispute. Hosting is managed by Cross Design for secure management. Transfer is possible later if the client desires.

You must verify the contract clauses regarding the settlement of costs up to the completed stage and the delivery of deliverables based on the progress (completion rate) evaluation.

You may deduct the number of days of delay from the balance by applying the 'delay penalty rate (typically 0.1% to 0.3% of the daily contract amount)' clause in the contract.

Typically, it is 1 to 3 years from the date of delivery and inspection completion, and covers bug/error corrections within the scope of production.

If a function that was originally in the plan/scope of work does not function properly, it is a 'defect', and adding new functions that were not there or changing the layout is 'additional development'.

If new business models, patented technologies, or unique business logic are involved, it is safer to sign an NDA before a meeting or when concluding a contract.

After delivery, there is typically an inspection period of 7 to 14 days, during which all functions, links, typos, and responsiveness issues must be fully tested.

It is common for companies to disclose their sites as part of their portfolios, but if you prefer them to remain private, you must discuss this in advance during the contract signing.

Drafted based on the standard software development contracts provided by the Fair Trade Commission or the Korea Software Industry Association (KOSA). Cross-design is followed.

It must be set to 'after final inspection,' when the final server migration, domain connection, administrator training, and manual delivery are completed.

We specify a clause in the contract prohibiting "re-subcontracting to a third party without the client's prior written consent." Cross Design does not outsource website development, design, coding, photography, video, etc.

You must receive the source code, DB dump files, and server/domain account connection information intact and back them up upon final delivery.

You can request the issuance of performance (contract) guarantee insurance and performance (defect) guarantee insurance policies through SGI Seoul Guarantee, etc. (fees and issuance terms negotiable). We typically handle projects for institutions and government agencies exceeding 5000 million KRW.

No. It is available on a case-by-case basis as needed. We will send you the maintenance price list. We will provide a manual, so you may manage the parts you can handle yourself.

Simple text editing or post registration can be done directly through the administrator page, so it is not mandatory. It is signed when periodic banner replacements, security patches, and feature updates are frequent.

Prices are determined based on the scope of work, such as simple hosting management/text editing (5 to 20 KRW per month) and regular design/publishing revision support (30 to 100 KRW or more per month).

It is also possible to calculate the work man-hours (hourly rate) and make a one-time payment whenever modifications are made, without a regular contract.

We provide a manual (PDF or video) on how to use the administrator page.

You must check whether daily/weekly automatic backups are configured on the hosting server, and familiarize yourself with the manual backup method for administrators before major updates.

In the event of an urgent failure, we provide support through available emergency channels (telephone, chat support, etc.).

We notify the client company of the person in charge 10 days in advance to prevent the process.

Since major plugin updates can conflict with themes or other plugins and cause the site to break, it is essential to use Cross Design for safety.

It is possible, but there may be costs for analyzing the existing source code (initial setup fees), or acceptance may be denied depending on code quality.

If you use a paid annual license, we will notify you one month before expiration and guide you through the renewal payment.

Apply reCAPTCHA (robot check) to prevent spam bots, set up administrator 2-step verification, and perform periodic password changes.

It may be necessary to increase hosting traffic capacity. If you contact us in advance regarding short-term high traffic (e.g., during events), we will implement measures to prevent server monitoring downtime.

If the client company owns the domain and hosting account, they can recover the data by downloading a server backup and transferring the code to a new maintenance provider. Cross Design Group is a company that has been growing steadily since 2012.

Rather than flashy sales pitches, it is to verify 1) whether they possess a portfolio of similar businesses within the last 1-2 years, 2) the transparency of detailed labor costs in the estimate, and 3) whether they have a clear contractual stance regarding defect repair and ownership attribution.

Even for the same functions, agencies are about 1.5 to 3 times more expensive than freelancers. Agencies offer higher stability because they include indirect costs such as the deployment of a Project Manager (PM), QA, and office maintenance expenses.

Since overtime, weekend work, or the deployment of additional personnel is required, a 'rush fee' of typically 20–30% of the total estimate is incurred. Cross Design has rarely added this cost to date.

Yes, if the screen design and function definition documents are perfect, the planning effort will be reduced, allowing you to save approximately 10–20% of the total estimate. However, if the plan is unprofessional and requires the vendor to redo it, a discount is not available.

No. The initial setup cost for the main page and the overall layout (header/footer) is the highest, and the unit price per page decreases as more sub-pages using the same template are added.

Yes, the labor cost per frontend developer handling that stack is relatively higher, and since backend separation work such as API integration is required, costs increase noticeably if it is a simple promotional website.

If a professional copywriter is involved, separate planning and manuscript fees ranging from 50 KRW to over 200 KRW are charged depending on the page volume and brand depth; however, we have maintained a database for 15 years and utilize AI-based learning to provide the optimal wording for our clients.

Cross Design handles all photography in-house. We do not outsource. We take full responsibility for the shoot. That is how your website truly shines. For a half-day (4-hour) shoot, actual expenses typically range from 60 to 100 KRW. There is a significant concern that general photographers charge by the hour and evade responsibility for the quality of the photos.

It is not double the price. Since the layout remains unchanged and only the text data is replaced, it is common for about 30% of the total estimate to be added per language (unlike other companies that rely on the client to provide the translation, Cross Design provides native speaker translations).

To implement Lottie animation or WebGL (3D), in addition to the publisher, it requires specialized interactive development effort, and depending on the difficulty of the effect, an additional cost ranging from a minimum of 50 won to 100 million won is added.

Using genuine licensed or paid stock images owned by the company solely within the site is free (including quotes), but if you wish to use those images in offline flyers or other advertisements, the client must purchase a license directly.

It becomes very expensive. Building a custom CMS, including features like Excel statistical downloads and menu separation by permission, is essentially equivalent to creating an additional backend program, which can add millions of won to the budget.

If you only handle WebView (hybrid) app packaging and store registration, which simply overlays the web, the cost is around 50 to 150 million won per OS, but if native app features (push notifications, GPS) are deeply incorporated, it goes up to tens of millions of won.

Billing is based on the number of days (M/D) required by the developer, calculated according to the amount of data to be integrated (number of APIs) and whether real-time synchronization is possible. This is a highly complex task requiring a minimum of 100 million KRW.

If you use a cross-design solution, setup is free, but for standalone development, API integration development effort is required, which may result in costs of approximately 10 to 30 won per platform.

In addition to the development integration fee, there are separate costs for the sign-up fee (approx. 5 to 10 won), annual fee, and per-transaction authentication fee (approx. 40 to 50 won) paid to authentication agencies (NICE, KCP, etc.).

An initial registration fee for the PG company (approximately 22 KRW, waived during promotions) is required, and thereafter, settlement is received after deducting a card fee of 2–3% for each payment.

The development cost for AlimTalk API integration (approximately 200,000 to 500,000 KRW) is a one-time expense, and thereafter, you must directly pay a fee of approximately 10 to 15 KRW per message sent to the AlimTalk top-up site.

Since you only need to copy and paste the plugin script, most companies set it up as a free service. However, ChannelTalk's own paid plans must be paid for separately.

Common domains such as .com and .co.kr incur a fixed annual fee of approximately 20,000 to 30,000 won through registration agencies (Gabia, Whois, etc.).

General enterprise shared hosting (such as Cafe24) is affordable at 1 to 3 won per month, but cloud servers that handle traffic exclusively (such as AWS EC2) cost anywhere from a minimum of 7 won to hundreds of thousands of won per month.

In cases where trust is important, such as in finance, shopping malls, companies, or hospitals, you must purchase a paid security certificate (5 to 15 won per year) and renew it annually.

If it is just simple popup replacement or text modification (1-2 cases per month), it is around 10 to 20 won, but if monthly banner design planning and page renewal are included, it is 50 to 100 won or more.

Depending on the page length and design complexity, the addition of standard subpages combining text and images is billed per case at approximately 10 to 30 won per page. For hospital-specific treatment pages, the cost is around 40 to 80 won.

Insertion of basic meta tags and registration with Naver/Google Search Advisor are free of charge; however, a separate marketing budget is required for top-ranking SEO through keyword analysis and advanced markup enhancement.

If planning or design work has already commenced, you may receive a refund minus the cost for the corresponding effort (payment for completed work), or you may even be required to pay a penalty fee. It is essential to check the early termination clause in the contract. Cross Design Group has not had a single cancellation during development from 2012 to the present. This is Cross's pride.

Unfortunately, it will be charged. Changing the design when the publishing and backend structures are already established is equivalent to starting over from scratch, resulting in massive additional costs.

No. Because analyzing spaghetti code written by others and untangling the complex logic actually takes more time, the cost often comes out higher than building it from scratch, or companies frequently refuse to take it over.

In accordance with industry practices, estimates are set about 10–20% higher than standard cash payments due to administrative paperwork, strict supervision, and the risk of payment delays.

It is possible, but it may not result in tax savings. If you do not issue a tax invoice, it becomes difficult to prove the facts of the contract in the event of a legal dispute. Furthermore, since companies are entitled to deduct VAT as input tax anyway, they must pay 10% and obtain qualified documentation.

If you try to cut the labor unit price itself, the quality of the deliverables (in terms of time invested) will suffer. Instead, it is wiser to negotiate the scope of work by saying things like, "We will provide all the original images and planning, so please deduct the planning effort," or "We will simplify the complex filter search function into a simple category, so please reduce the cost."
