Without a solid contract, you're exposed to scope creep, unpaid invoices, and legal disputes that drain your development business. A well-drafted WordPress development contract protects both you and your client while setting clear expectations from day one.
Why WordPress Developers Need Contracts
WordPress projects range from simple theme customization to complex custom plugin development, and ambiguity breeds conflict. A contract forces you and your client to agree on deliverables, timelines, payment terms, and revision limits before any code is written. It's especially critical when working with agencies or non-technical clients who may not understand why a "simple" feature request takes 40 hours.
Without documented terms, you'll face situations like:
- Clients requesting unlimited revisions after launch
- Scope changes mid-project without additional compensation
- Disputes over who owns custom code or custom post types
- Payment delays or refusal because "it's not quite what I imagined"
Key Sections Your Contract Must Include
Project Scope & Deliverables
Define exactly what you're building. Instead of "WordPress website," specify: "Custom WordPress site with 8 static pages, WooCommerce store with 50 products, custom product filtering plugin, and integration with Stripe payment gateway." Include what's not included—SEO optimization, content creation, hosting setup, or ongoing maintenance should be separate line items.
Timeline & Milestones
Typical WordPress projects take 4–12 weeks depending on complexity. Break the project into phases with specific completion dates. For example: week 2 (design approval), week 5 (core development), week 8 (testing), week 10 (launch). This prevents the ambiguous "we'll be done when we're done" situation that frustrates both parties.
Payment Terms
Specify your payment schedule. A common approach for WordPress work:
- 50% upfront upon contract signing
- 25% at mid-project milestone (design approval or core development complete)
- 25% upon launch and client sign-off
Include late payment penalties (e.g., 1.5% monthly interest on invoices unpaid after 30 days) and your right to pause work if payment is more than 7 days overdue. Set a minimum project fee if you work hourly—many developers use $2,500–$5,000 minimums to account for discovery and admin work.
Revisions & Change Requests
Specify how many revision rounds are included (typically 2–3 per phase). After that, charge $50–$150 per hour for additional changes. Define scope creep clearly: "Requests to add pages, plugins, or features beyond the original scope require a change order and timeline adjustment."
Intellectual Property Rights
Clarify ownership. Most developers grant clients full ownership of the custom WordPress site and custom-built functionality after final payment. However, you retain rights to custom frameworks, plugins you've developed independently, and your general methodologies. If the client needs a custom plugin you've built to remain proprietary or be used on other projects, that should be explicitly stated and possibly cost more.
Support & Maintenance
Separate post-launch support from development. Many WordPress developers offer 30–60 days of free bug fixes after launch, then transition to a retainer (typically $200–$500/month) for ongoing maintenance, updates, security patches, and minor changes. Be explicit: ongoing support does not include new feature development or major redesigns.
Termination Clause
State what happens if either party wants to exit. You might offer clients a full refund if they cancel before 25% of work is complete, partial refund up to 50% completion, and no refund after that point. Clarify whether you'll transfer the project to another developer and how long that transition takes.
Security & Hosting Responsibility
Specify who manages hosting, SSL certificates, backups, and updates. Many WordPress developers recommend clients purchase hosting independently (avoiding vendor lock-in) but offer managed hosting recommendations. Make it clear that you're not responsible for server downtime or data loss if the client chooses budget hosting.
Protecting Yourself Legally
Use a contract template tailored to your state or country's laws. Services like Rocket Lawyer ($50–$200 for WordPress-specific templates) or Proposify (which integrates project management) save time over custom legal drafting. Have a lawyer review your template once (cost: $300–$800) rather than for every contract.
Include a dispute resolution clause specifying mediation or arbitration before litigation—it's faster and cheaper than court.

Frequently Asked Questions
Q: Can I use a contract template I found online, or do I need a lawyer? A template is a solid starting point (and better than nothing), but having a lawyer spend an hour reviewing and customizing it for your state ensures enforceability and protects you from costly gaps.
Q: What if a client refuses to sign a contract? Walk away. Clients who won't commit to written terms are red flags for payment problems and disputes later.
Q: Should I charge differently for maintenance vs. development retainers? Yes—maintenance retainers ($150–$400/month) are lower-friction and predictable, while development retainers ($1,500–$5,000+/month) justify feature work and strategic enhancements.
