Web Development Invoice Template: Bill Dev Projects

Web development projects span weeks with multiple deliverables. Your invoice structure should match your project milestones.

Web Dev Invoice Structure

Break projects into logical billing units:

  1. Discovery and wireframes — $2,000
  2. Frontend development — $4,500
  3. Backend and API integration — $3,500
  4. Testing and launch — $1,500
  5. Monthly maintenance retainer — $500/mo

Hourly Overflow Billing

When scope exceeds fixed price, bill overflow hours separately with pre-approved hourly rate. Reference change order number.

Hosting and Third-Party Costs

Pass-through costs (hosting, domain, premium plugins, stock assets) should be separate line items with receipts attached.

Maintenance Retainer Invoices

Monthly retainer invoice should list: hours included, hours used, response time SLA, and any overage.
