What should be included in a software development contract?

The Core Clauses Every Software Contract Needs

Whether you're hiring a freelancer, an agency, or a dedicated team, the contract is your primary risk management tool. Here's what it must cover:

1. Scope of Work (SOW)

The SOW defines exactly what will be built — features, platforms, integrations, and what is explicitly out of scope. Vague scope is the root cause of most budget overruns and delivery disputes. Attach wireframes, user stories, or a feature list as an exhibit if needed.

2. Deliverables and Acceptance Criteria

List each deliverable and specify how it will be reviewed and accepted. Acceptance criteria protect both parties: the client knows what to expect, and the vendor knows when their obligation is met.

3. Timeline and Milestones

Break the project into milestones with target dates. Tie payment to milestone completion rather than calendar dates alone. Include provisions for delays caused by either party.

4. Payment Terms

Specify the total fee or rate, payment schedule, invoicing process, late-payment penalties, and what happens if the project is paused or cancelled mid-way. Fixed-price, time-and-materials, and milestone-based are the three common structures — each has tradeoffs.

5. Intellectual Property Ownership

This is the clause clients most often overlook. The contract must state clearly that the client owns all code, designs, and data upon full payment — including third-party libraries (with license details noted). If the vendor retains any rights (e.g., to reusable internal frameworks), that must be explicit. Avoid arrangements where IP transfers only at project end; tie partial transfer to each paid milestone.

6. Confidentiality and NDA

Even if a separate NDA is signed upfront, the contract should restate confidentiality obligations covering source code, business logic, user data, and commercial terms.

7. Warranties and Bug Fixes

Define a post-launch warranty period (typically 30–90 days) during which the vendor fixes defects at no additional cost. Distinguish between bug fixes (in scope) and new features (not in scope).

8. Change Management Process

Any request to change scope should go through a written change-order process with an agreed impact on price and timeline. Without this, scope creep is almost inevitable.

9. Limitation of Liability

Both parties should agree on a cap for damages — usually capped at the total fees paid. Unlimited liability clauses are rarely enforceable and deter good vendors.

10. Termination and Exit Rights

Specify conditions under which either party can exit, notice periods, what deliverables and payments are owed at termination, and how the codebase is handed over.

11. Governing Law and Dispute Resolution

Specify the jurisdiction and whether disputes go to arbitration, mediation, or court. For cross-border engagements (e.g., a US company hiring an India-based studio), this clause needs extra care.

A Note on Vendor Practices

When evaluating vendors, look for those who lead with an NDA, give you full IP ownership as a default, and use milestone-based pricing — these signal a client-first operating model. CodeNicely, for example, operates on an NDA-first, client-owns-100%-of-IP basis with milestone payments, which aligns incentives throughout the project.
