You signed a website development contract and see five pages of legal text – what should you actually check before signing? The short answer: ownership of the code and content, a clear scope of work, revision rounds, milestones with specific dates (not “as soon as possible”), post-launch support terms, and clearly defined handover conditions. Missing any of these elements is a signal to ask for additions before you sign.
This article breaks down exactly what a good contract should contain — not generic legal boilerplate, but the practical clauses that actually protect you. If you’re still at the stage of choosing a contractor, see our guide on how to choose a website contractor, and if you already have a specific offer in front of you, read the article on how to evaluate a website proposal. Keep in mind that a good written contract benefits both sides — so we share honestly what to look for, regardless of whether you work with us or another contractor.
The quick reference: 6 mandatory clauses
| Clause | What it should say | Why it matters |
|---|---|---|
| Ownership | Who owns the code, design, and content after payment | Prevents dependency on the contractor |
| Scope | Exact page count, features, included revisions | Prevents hidden “scope creep” |
| Milestones | Specific dates per phase, not general timeframes | Gives a basis for tracking progress |
| Payment | Broken down by stage, not 100% upfront | Protects both sides from risk |
| Support | What’s included after launch and for how long | Prevents unexpected costs |
| Termination | Terms for exiting the project from either side | Protects against a failed partnership |
Ownership: the most important clause, and the one most often skipped
Ownership over the final product is the clause that causes the most problems when it’s missing. The contract should clearly state that after full payment, the client receives full ownership over the source code, design, and all content — not a usage license, but genuine ownership.
Watch out for wording that keeps rights with the contractor around “proprietary CMS” or “patented technology” with no clear alternative. If the contractor uses a proprietary, closed platform, ask explicitly what happens if you later decide to switch contractors — can you take the site with you, or are you locked in for good.
The domain itself should be registered in your name from the very start, not the agency’s “for convenience.” Under ICANN’s registrant policies, the domain registrant is its legal owner — so it’s critical that you, not the contractor, are listed as such in the WHOIS record. If the domain is already registered by the contractor, the contract should explicitly include a clause for transferring ownership upon request.
Scope of work: protection against hidden “scope creep”
A good contract describes exactly what’s included in the project — number of unique pages, specific features, number of included design revisions. Clauses like “website development per the offer” with no specifics leave too much room for different interpretations later in the project.
It’s especially important that the number of revisions be explicitly stated — two or three rounds of corrections to the main concept is a reasonable standard. Without this limit, you risk an open-ended cycle of changes that stalls the project indefinitely, or the opposite — the contractor refusing further corrections by citing the lack of a contractual clause.
If the project includes third-party integrations — payment processors, CRM, courier services — they should be explicitly listed in the scope, not assumed as “included by default.” Under the Bulgarian Obligations and Contracts Act, contractual freedom between the parties is broad, which is exactly why specificity in the contract itself is the only real protection in a dispute.
Milestones and phases: specific dates, not general timeframes
The contract should include a specific timeline with dates per phase — when you’ll see the first visuals, when you’ll have the chance for revisions, what the final launch deadline is. Wording like “as soon as possible” or “within a reasonable timeframe” offers no real protection if delays occur.
It also helps if the timeline includes buffer time for delays on the client’s side — for example, late delivery of content — so it’s clear who bears responsibility for keeping the project on track beyond the original deadline. For more on realistic timeframes for the different phases, see our guide on the key stages of website development.
Payment: why staged installments protect both sides
Paying 100% upfront is a risk for the client — the contractor has no financial incentive to finish the project on time once they’ve already received the full amount. The opposite — 100% payment only after completion — is a risk for the contractor, especially on longer projects with real expenses along the way.
A balanced model usually includes an advance payment at the start (for example 30–50%), an intermediate payment upon design approval, and a final payment upon launch. This structure gives both sides a financial incentive to bring the project to completion correctly and on time.
Post-launch support: what exactly is included
Many contracts silently assume that support is a separate service after the project delivery, but not all clients understand it that way when signing. A good contract explicitly states whether a free bug-fix support period is included (for example 30 days), and what the terms are after that.
If support isn’t included in the initial offer, the contract should at least indicate an indicative price for a future subscription, so you’re not caught off guard by an unexpectedly high price when you actually need help. A full methodology for evaluating support costs is available in our website maintenance guide.
Common mistakes when signing a contract
In consultations with clients, we see the same mistakes repeated systematically. The first is signing without an explicit ownership clause, which only becomes a problem once the client decides to switch contractors. The second is accepting an undefined scope “per the offer,” with no specific page count or number of revisions. The third is agreeing to 100% upfront payment with no staged breakdown. The fourth is a lack of specific dates in the timeline, only general timeframes. The fifth is skipping the post-launch support clause, leading to unexpected costs later. The sixth is unclear termination terms in case of a failed partnership. The seventh is trusting oral agreements with no written confirmation in the final document.
Frequently asked questions
Is a written contract mandatory?
It’s not legally required for all types of services, but it’s strongly recommended for a project of this scope and duration. An oral agreement offers no real protection in a dispute over scope, timelines, or ownership.
Who should own the domain — the client or the agency?
The domain should be registered in the client’s name from the very start, even if the agency manages the technical setup. If it’s already registered by the contractor, the contract should explicitly include a clause for transfer upon request.
What happens if the contractor misses deadlines?
A good contract includes an explicit clause for penalties or alternative remedies for missed deadlines, drawing on general contract law principles. Without such a clause, the only real option in a serious delay is to terminate the contract, which is rarely a good outcome for either side.
Do I have to pay 100% upfront?
It’s not recommended. A staged breakdown — advance, mid-project payment, and final payment at launch — financially protects both sides and gives a genuine incentive for timely completion.
Is support automatically included in the development contract?
Generally not, unless it’s explicitly stated. Many contracts include a short free period for fixing bugs (for example 30 days), but full ongoing support is usually a separate, contracted service.
Can I terminate the contract midway through the project?
It depends entirely on the termination clauses in the contract itself. A good contract states the terms for termination from either side, including how already completed work and payments made are handled at the point of termination.
What do I do if the contractor refuses to provide an ownership clause?
That’s a serious red flag that warrants careful consideration before signing. A legitimate contractor has no reason to refuse an explicit ownership clause over a product the client is paying the full contract price for.
Conclusion: the contract is protection, not formality
A website development contract isn’t a bureaucratic obstacle between you and the finished product — it’s the tool that prevents most real-world disputes later in the project. The six clauses covered here — ownership, scope, milestones, payment, support, and termination — cover nearly every scenario in which projects actually stall or create conflict.
