Invoice Template for WordPress Developers
WordPress development billing is complicated by the perception that WordPress is free — clients assume my work is mostly 'clicking around' and struggle to understand why custom plugin development costs as much as bespoke software. My second challenge is scoping security and performance work, which is genuinely complex but invisible to clients who only see the front-end result.

What to include on your invoice
WordPress developers bill across theme, plugin, and maintenance categories. Custom Theme Development covers building a WordPress theme from scratch using PHP, the WordPress Template Hierarchy, and Gutenberg block patterns — distinct from editing a pre-built theme. Custom Plugin Development refers to writing a WordPress plugin with a proper activation hook, admin settings page, and front-end shortcode or block output. WooCommerce Customisation covers modifying the checkout flow, adding custom product types, or integrating payment gateways beyond the standard WooCommerce options. Site Migration and Staging Setup covers moving a WordPress site between hosts, setting up a staging environment, and configuring a deployment workflow. Maintenance and Security covers updating plugins, applying security patches, setting up backups, and monitoring uptime on an ongoing monthly basis.
How to price your work
WordPress developers price custom theme builds at $2,000–$10,000. Plugin development: $1,000–$8,000. Site migrations: $500–$2,000. Maintenance retainers of $150–$500/month are extremely common and provide stable recurring revenue. Hourly rates: $50–$120/hr. WooCommerce customisation commands a premium — $80–$150/hr or fixed project rates. Avoid competing on price with template installers; position on security, performance, and custom development expertise.
Getting paid faster
WordPress clients are often small business owners who manage their own site day-to-day. Describe work in plain English on every line item — 'Plugin to show customer reviews on product pages' instead of 'Custom WP plugin with CPT and shortcode.' Clear descriptions get approved faster. For maintenance clients, set up automatic monthly billing so you never have to chase the same invoice twice.
