What a Shopify Development Contract Should Include

Most development disputes are not really contract disputes. They are disagreements about what was agreed, happening between parties who never wrote it down clearly.

Which is the useful way to think about a development contract. Its main job is not to help you win a legal argument — cross-border enforcement in particular is impractical enough that you will probably never pursue one. Its job is to make the argument unnecessary by establishing, in advance, what each side owes the other and what happens when things change.

Here is what should be in one, ordered by how often each item causes trouble.

The clauses that cause the most trouble when missing

Intellectual property ownership. The single most consequential clause and the most commonly vague. The contract should state plainly that on payment, all custom work created for you — theme code, custom sections, apps, integrations, scripts, design files — belongs to you.

Watch for arrangements where the developer retains ownership and grants you a licence. This means you cannot take the code elsewhere, modify it freely, or in some cases continue using it if the relationship ends. It is occasionally reasonable for truly reusable proprietary frameworks, and it should be disclosed explicitly rather than buried.

Also address third-party components: open-source libraries, purchased themes, and licensed assets, each of which carries its own terms that neither party can override.

Account and credential ownership. Your Shopify admin, domain registration, and app accounts should be in your name, with you as owner. The developer gets staff or collaborator access, which you can revoke.

This is not a trust issue, it is a structural one. Developers who set up accounts under their own name usually do it for convenience, and the consequence is that you cannot remove them, cannot transfer the store, and in a dispute have no control over your own business. Get it stated, and check the actual account settings rather than relying on the clause.

Scope, in writing, including exclusions. The contract should reference a specific scope document with a date and version. What is included, and — more usefully — what is explicitly excluded. Most scope disputes are about things nobody mentioned, so the exclusions list is the valuable half.

The change request process. How a change is raised, how its cost and timeline impact are assessed, who approves it, and at what rate. Without this, every clarification becomes a negotiation. A good clause also acknowledges that trivial changes get absorbed rather than processed.

Payment schedule tied to deliverables. Stages linked to things you can see and verify, not to dates or percentages of elapsed time. This is your primary practical protection, particularly with a supplier you cannot realistically pursue legally.

Handover obligations. What you receive at the end: code access, documentation, credentials, an explanation of custom work, and a stated willingness to brief a successor. Make this a deliverable rather than a courtesy, because goodwill is unreliable at the end of a difficult project.

The clauses about what happens when things go wrong

Defect remedy and warranty period. A defined period after launch — commonly thirty to ninety days — during which the developer fixes defects in their own work at no charge. The clause must distinguish between a defect, meaning it does not work as specified, and a change, meaning you want something different. That distinction prevents most post-launch disputes.

Termination rights for both parties, with notice periods and what happens to work in progress and payments already made. A contract you cannot exit is a contract you should not sign.

What happens on termination. You should receive all work completed to date, all credentials, and all documentation, regardless of why the relationship ended. This clause is easy to agree at the start and impossible to negotiate later.

Timeline treatment. Whether dates are targets or commitments, and what happens if they slip. Be realistic here: most development timelines are estimates, and a contract pretending otherwise either creates false comfort or pushes the developer into padding. What matters more is a notification obligation — the developer must tell you promptly when something will be late.

Client dependency handling. What happens if you are late supplying content, approvals, or access. Projects overrun on client delay at least as often as on development, and a clause that addresses this fairly protects both sides.

Liability limits. Almost every development contract caps liability, typically at fees paid. This is normal and largely unavoidable. What you should notice is whether the cap is unusually low relative to the project value, and whether it excludes things it should not.

Dispute resolution and jurisdiction. Which law applies and where disputes are heard. For a cross-border engagement, be realistic: a clause naming a foreign jurisdiction is a clause you will not use. This is precisely why staged payments matter more than legal remedies.

The clauses people forget

Confidentiality, both ways. They see your data, your customers, and your commercials. You may see their processes. Mutual is standard.

Data protection. If the developer handles customer data — and anyone with admin access does — your obligations under GDPR or equivalent legislation extend to them. You likely need a data processing agreement. This is frequently omitted from small engagements and it does not become optional because the engagement is small.

Subcontracting. Whether they may subcontract, whether they must disclose it, and that they remain responsible for subcontracted work. Undisclosed subcontracting is common enough to be worth a clause.

Named personnel, if you selected the supplier partly on specific people. Not always achievable, and worth asking for.

Use of your store as a portfolio piece. Most developers want to, most clients do not mind, and it should be consented rather than assumed. If your store is confidential, say so.

Third-party costs. Who pays for themes, apps, plugins, and licences, and in whose account they sit. App subscriptions in the developer’s account is a small version of the credential problem.

Ongoing support terms, distinct from the project. If a maintenance arrangement follows the build, that is a separate agreement with its own scope, response expectations, and notice period.

Code standards and documentation requirements. Unusual in small contracts and worth including: that code will be commented, that custom functionality will be documented, and that a staging environment and version control will be used.

For migrations specifically

Migration projects benefit from a few additional items, because the risk is concentrated in specific places.

Explicit SEO responsibility. Who builds the redirect map, who verifies it, and who monitors after launch. State it, because the default assumption differs between parties and the cost of the gap is enormous.

Data completeness obligations. That all agreed data will be migrated and verified, with a reconciliation step.

A defined verification and sign-off process before go-live, listing what will be checked.

Rollback provisions, where practical.

Post-launch monitoring, and who does it for how long.

Subscription-specific terms if you have subscribers: confirmation that payment portability was established, and what happens if it turns out to be incomplete.

A worked example: the clause that was not there

A homeware brand fell out with their developer roughly seven months into an ongoing relationship. The dispute itself was ordinary — a disagreement about whether some work was within an agreed retainer.

What made it expensive was the contract. It was a two-page document covering payment terms and little else.

It did not address IP ownership, so when the client wanted to take the custom functionality to another developer, the original developer claimed the code as their own and refused to hand over the source for a custom product configurator they had built.

It did not address account ownership, and the Shopify store had been created under the developer’s account with the client as staff. The domain was registered to the developer’s agency. Two apps were subscribed under the developer’s billing.

It did not address handover, so there was no obligation to provide documentation, and there was none.

The practical resolution took four months and a settlement payment. The client rebuilt the configurator from scratch with a new developer, transferred the domain through a registrar dispute process, and recreated the store ownership structure. None of the work was technically difficult. All of it was slow, and all of it was avoidable.

The developer was not acting in bad faith throughout, incidentally. They believed the code was theirs, because nothing said otherwise. That is what an absent clause produces: two reasonable parties with incompatible assumptions and no way to resolve them.

What to do practically

Read it, particularly the boring parts. IP, termination, and handover are where the consequential language sits, and they are the sections people skim.

Have a solicitor review anything substantial. A few hundred spent on review against a five-figure project is proportionate.

Do not accept a two-page agreement for a large project. Thin contracts are not friendly, they are unspecified.

Insist on the scope document being referenced by name, date, and version.

Check the account settings, not just the clause. Log into Shopify and confirm you are the owner. Check the domain registrant. Check whose card the apps are on. Clauses describe intentions; settings describe reality.

Negotiate what matters and concede what does not. Liability caps are usually non-negotiable and rarely the real risk. IP ownership, account control, and handover obligations are worth pressing hard on.

Keep everything. The contract, the scope document, every change request, and written confirmation of decisions. Most disputes are resolved by whoever has the better record.

Structuring the payment schedule

Since staged payments are the protection that works regardless of jurisdiction, it is worth being specific about how to structure them.

Tie stages to verifiable deliverables, not dates or percentages of elapsed time. “40% on completion of the staging build, reviewed and accepted by us” is enforceable in practice because you can look at it. “40% at week six” is not, because week six arrives whether or not anything happened.

Keep the deposit proportionate. Some upfront payment is entirely reasonable — it covers initial work and demonstrates commitment on both sides. A large proportion before any output is not, because it leaves you with no leverage at precisely the point you know least about how the engagement will go.

Hold a meaningful final payment until after launch and verification. A retention until the store is live, tested, and the agreed checks have passed aligns everyone’s interest in a clean launch. Make the release conditions specific rather than subjective, so it cannot become a way of withholding payment indefinitely.

Define acceptance. What does “accepted” mean, who decides, and within how many days? Without a defined acceptance window, a stage can sit unapproved forever, which is unfair to the developer and creates its own dispute.

More stages on a longer project. A six-month engagement with three payments concentrates risk; the same project with six or eight stages means neither side is ever far out of pocket.

For an ongoing retainer, monthly in advance or arrears is normal. What matters more is the notice period and what happens to unused hours — whether they roll over, expire, or are forfeited.

Never pay for a stage you have not seen. This sounds obvious and is routinely breached under deadline pressure, usually with a promise to catch up on review later.

What a fair contract looks like from the other side

Worth understanding, because a contract that is one-sided in your favour attracts worse suppliers rather than better ones.

Developers need protection from scope creep as much as you need protection from under-delivery. A change request process with a stated rate is not the developer being difficult; it is the mechanism that lets them absorb small things graciously without absorbing everything.

They need protection from client delay. If your content arrives three weeks late and your approvals take a fortnight each, the timeline is not their failure. A clause addressing client dependencies fairly is reasonable, and its absence tends to produce padding in the estimate instead.

They need a defined acceptance process, so a project can actually finish. Open-ended review is how engagements drift indefinitely.

They need payment certainty. Late payment is the most common client-side breach by a wide margin, and developers price for it. Paying promptly is a genuine commercial advantage in supplier relationships.

They need liability caps. No small team can accept unlimited liability for consequential losses on a store turning over millions. Pushing hard on this either gets you a refusal or a much higher price.

They need to say no. A contract that obliges a developer to accept any request within a vague scope is not enforceable in spirit and will produce resentment rather than compliance.

The contracts that work best are the ones both parties would sign from either side of the table. If yours is only defensible from your position, good suppliers will decline it and you will end up with whoever is desperate enough to accept.

The bottom line

A development contract’s real function is preventing disagreements, not winning them — especially across borders, where enforcement is theoretical.

Get four things right and you have covered most of the risk: custom work belongs to you on payment, every account is in your name with you as owner, the scope document is referenced explicitly with its exclusions listed, and handover obligations are a deliverable rather than a favour.

Then stage your payments against verifiable deliverables, because that is the protection that works regardless of jurisdiction, goodwill, or how the relationship ends. A development engagement with those five things in place is recoverable even when it goes wrong — which is the most a contract can realistically do for you.

Frequently asked questions

Who owns the code in a Shopify development project?

You should, on payment, and the contract should say so explicitly for all custom work — theme code, custom sections, apps, integrations, and design files. Watch for arrangements where the developer retains ownership and grants you a licence, which means you cannot take the code elsewhere or modify it freely, and in some cases cannot keep using it if the relationship ends. That structure is occasionally defensible for truly reusable proprietary frameworks and should always be disclosed rather than buried. Third-party components like purchased themes and open-source libraries carry their own terms that neither party can override.

Should my Shopify store be in my name or my developer’s?

Always yours, with you as the store owner and the developer holding staff or collaborator access you can revoke. The same applies to your domain registration and any app subscriptions. Developers who set accounts up under their own name usually do it for convenience rather than leverage, but the consequence is identical: you cannot remove them, cannot transfer the store cleanly, and have no control over your own business if the relationship sours. Check the actual account settings rather than relying on a contract clause, since the settings are what determine what you can do.

What should be in a Shopify development contract?

The four clauses that cause the most trouble when missing are IP ownership of custom work, account and credential ownership, a referenced scope document including explicit exclusions, and handover obligations stated as a deliverable. Then add a change request process with a rate, payments staged against verifiable deliverables, a defect warranty period that distinguishes defects from changes, and termination rights for both sides covering what you receive on exit. For migrations, add explicit SEO responsibility and a verification process before go-live.

Is a contract worth it when hiring an overseas developer?

Worth having, though not for the reason people assume. Cross-border enforcement is impractical enough that you will probably never pursue a claim, so the contract’s value is in establishing shared expectations and preventing the disagreement rather than in providing a remedy. What actually protects you is structural: staged payments against deliverables so your exposure is bounded, owning every account yourself, and starting with a small engagement. Get IP ownership and handover obligations written down, then rely on structure rather than on a jurisdiction clause you will not use.

What is a reasonable warranty period after a Shopify build?

Commonly thirty to ninety days, during which the developer fixes defects in their own work at no charge. The important part is not the length but the definition: the contract should distinguish a defect, meaning something does not work as specified, from a change, meaning you have decided you want something different. Without that distinction you will either be charged for genuine bugs or find yourself arguing about whether a request is new work. Also establish what happens after the warranty ends, since that is usually where a maintenance arrangement begins.

Do I need a data processing agreement with my Shopify developer?

Very likely, if they have admin access to your store — which means access to customer names, addresses, order history, and in some cases payment metadata. Under GDPR and equivalent regimes your obligations as data controller extend to processors acting on your behalf, and a developer with admin access is a processor. This gets omitted from smaller engagements routinely, and the size of the engagement does not change the obligation. Ask your developer whether they have a standard DPA; established agencies usually do. If you handle data from regulated sectors or multiple jurisdictions, get this reviewed properly rather than relying on a template.

Can I use a template contract for Shopify development work?

For small, well-defined work a good template is usually adequate, provided you check it covers IP ownership of custom work, account ownership, scope with exclusions, and handover. For anything substantial, have a solicitor review it — a few hundred against a five-figure project is proportionate, and templates commonly miss the clauses that matter most in this specific field. The bigger risk with templates is not what they say but what they omit: generic software agreements rarely address staging environments, credential ownership, migration SEO responsibility, or app subscription billing, all of which cause real disputes.
