How should a website development contract in Xi'an define the scope of source code delivery?

When signing a contract for website development in Xi’an, “delivery of all source code” is not sufficiently specific. Clearly specify which files will be delivered, how they may be used, whether the site can be deployed independently, and how it can be migrated if the service is discontinued. Receiving a compressed code package does not mean that you acquire all copyrights, nor does it mean another service provider can continue maintaining the site.

Before comparing quotes, first confirm whether the project involves custom development, secondary development of an open-source system, or website development on a SaaS platform. The scope of deliverables differs across these three models, so the contract should not use the same blanket statement, such as “the source code belongs to Party A,” to cover them all.

Distinguish custom code, third-party components, and platform licenses

For a custom development project, you can agree to delivery of the front-end and back-end code newly created for the project, along with the rights to modify, deploy, and commission its maintenance. Whether the service provider’s pre-existing general-purpose frameworks and tool libraries are included must be specified separately; do not assume they are automatically transferred with the project.

For a website developed based on an open-source system, distinguish the original program, commercial plugins, and newly developed code. Open source does not mean there are no terms of use. Even if a commercial plugin has been installed, it may be subject to requirements such as domain binding, limits on the number of sites, or renewal fees upon expiration.

SaaS website services generally provide access to a platform, and the platform’s underlying source code is usually outside the scope of delivery. In this case, pay closer attention to content and data export, domain management, renewal rules, and exit arrangements. If your business specifically requires self-hosted deployment, rule out options that do not support this requirement during the selection stage.

For example, when evaluating an integrated SaaS solution for website development and overseas marketing, such as 易营宝, ask separately about platform usage rights, website data export, and marketing account management. Do not interpret “website development services” as “delivery of the platform’s source code.”

Specify the source code scope in an appendix, matching each item to website functionality

The contract appendix can use a format such as “deliverable, file contents, scope of rights, and restrictions.” For anything that will not be delivered, specify its name, purpose, and replacement or renewal terms to avoid discovering during acceptance that a core function depends on an additional license.

• Website program: Front-end source files, back-end business code, styles, scripts, and related configuration templates. Providing only browser-accessible pages or compressed executable files does not constitute delivery of maintainable source code.
• Database and content: Database schema, data backups within the agreed scope, and uploaded files such as images, videos, and attachments. An empty database delivered before launch is not a substitute for migrating data generated during operation.
• Deployment materials: Runtime environment versions, dependency lists, installation steps, build commands, and scheduled task instructions, enabling the incoming team to deploy the site according to the documentation.
• Dependencies and licenses: A list of open-source components, commercial themes, fonts, plugins, and external interfaces, specifying the license holder, validity period, party responsible for fees, and migration restrictions.

Whether design source files, the complete development history, and internal testing tools will be delivered should also be specified separately, so they are not confused with code required to run the website. Sensitive information such as passwords and API keys should be transferred securely and changed after handover.

“Delivery of source code” and “ownership of copyright” must be agreed separately

Source code is a deliverable; copyright ownership and usage licenses are matters of rights allocation. The contract should distinguish among new project deliverables, the service provider’s pre-existing materials, and third-party deliverables, then specify ownership or the scope of licenses for each separately.

If the main goal is to avoid being dependent on the original service provider for future maintenance, clearly specify whether your business may modify the site independently, commission another team to maintain it, migrate it to another server, and deploy it within the agreed scope. Merely stating “perpetual use” may still leave deployment limits, authorized users, and modification rights unclear.

If you do require the relevant copyrights in custom-developed deliverables to be transferred, specify the particular rights, the deliverables they apply to, and the conditions under which the transfer takes effect. Third-party components must be used in accordance with their licenses; a blanket contractual provision cannot replace the original licensing terms.

Acceptance should involve more than checking whether a compressed package opens

A more valuable acceptance process is to deploy the site in an independent environment specified in the contract, using the delivered materials, and check core functions such as page access, admin login, content publishing, form submission, and file uploads. If the site uses inquiry email, payment, or logistics interfaces, also check that they work after the relevant accounts have been reconfigured.

This can reveal a common problem: the files appear complete, but the website still depends on undisclosed interfaces, license servers, or encryption modules provided by the service provider, and stops working when moved to a new environment. Any dependencies that are allowed to remain should have their usage terms and fees specified in advance.

When migrating a marketing website, also preserve valuable page URLs, SEO titles and descriptions, redirect rules, and any necessary analytics and conversion tracking configurations. Being able to open the website does not mean the existing promotional work has been fully carried over.

The contract should include source code delivery, deployment verification, and defect resolution as acceptance criteria, and link the corresponding payment milestones to the acceptance results. For code modified after launch, specify the delivery timeline for updates to prevent receiving an outdated version.

The price should account for the cost of taking over the site later

When comparing website development quotes in Xi’an, break down the development fee, source code delivery fee, third-party license fees, deployment and migration fees, and ongoing service fees. A low quote that depends on interfaces with long-term fees may increase exit costs; requiring the transfer of all general-purpose underlying code may also increase the initial investment.

Websites that require long-term secondary development, integration with multiple systems, or in-house operation and maintenance are better suited to arrangements that prioritize independent deployment and maintenance rights. For a standard informational website using SaaS services, focus on data export, predictable fees, and migration arrangements upon termination.

How to put the terms into practice

The following wording can serve as a basis for the delivery clause, with the specific details completed in an appendix:

“Party B shall deliver, in accordance with the appendix titled ‘Source Code and Supporting Materials Delivery List,’ the program source files, database schema and agreed data, resource files, dependency list, and deployment documentation corresponding to the version that has passed final acceptance. Ownership, license scope, and restrictions for new project deliverables, Party B’s pre-existing materials, and third-party components shall be governed separately by the appendix. The delivered materials must be deployable in the agreed environment by following the documentation and must pass the agreed functional acceptance tests. If an undisclosed essential dependency prevents deployment or operation, Party B shall provide or repair it within the agreed period.”

Also specify the delivery date, defect resolution period, scope of migration assistance, and remedies for breach. Before signing, ask the service provider to complete each item in the list. This makes it easier to determine what you are actually getting for the fee than retaining a vague statement that “all source code will be delivered.”
