Start with scope and goals

Begin by writing a concise brief that states the plugin’s purpose, required WordPress versions, PHP compatibility, performance and security expectations, integrations (APIs, payment gateways, CRMs), and maintenance needs. Add an expected timeline and a realistic budget range so candidates know whether they’re a fit.

Where to find and vet candidates

Choose between freelancers, specialist agencies, or in-house hires. Look for developers who can show:

  • Relevant portfolio — live plugins, GitHub or plugin repository links.
  • Code quality — readable, documented, and following WordPress coding standards.
  • Security and testing — examples of sanitization, nonces, unit or integration tests.
  • References — past clients or case studies with measurable outcomes.

If you prefer an agency, consider options like Thinkit Media for managed projects and ongoing support.

Interview and trial

  1. Ask about specific plugin development experience, use of hooks, shortcodes, custom post types, and REST API work.
  2. Request a small paid trial task or code review of an existing plugin.
  3. Evaluate communication, responsiveness, and documentation habits.

Finally, use a clear contract covering deliverables, IP assignment, staging and production deployment, acceptance criteria, payment milestones, and a maintenance agreement. That structure reduces risk and helps you build a reliable working relationship.
