Our WordPress Plugin Process
A six-step rhythm engineered so your plugin clears the WordPress.org review queue — and your customers do not raise security tickets.
Discovery & Scope
We understand your workflow, WordPress site footprint, theme constraints, integrations, and whether the plugin is for your own site or a public release.
Architecture & Hook Plan
Custom post types, taxonomies, admin pages, settings architecture, REST endpoints, hooks, filters, and database schema — designed for compatibility and updates.
Build with WP Standards
PHPCS WordPress Coding Standards, nonces on every form, capability checks on every action, prepared SQL, escaped output, and translation strings everywhere.
Security & Performance
Capability checks, nonces, SQL injection guards, XSS escaping, secret management, query optimisation, object caching, and load testing against realistic site sizes.
Release & Repository Listing
readme.txt, screenshots, banner assets, support email, SVN-based release to WordPress.org if applicable, or direct delivery to your site with update server.
Maintenance & Support
Compatibility with new WordPress versions, security patches, feature releases, support tickets, and migration scripts when a core API changes.

Frequently Asked Questions
Common questions WordPress agencies, store owners, and plugin authors ask before engaging a development partner.
Can you list our plugin on WordPress.org?
Yes — we build plugins to repository standards from the start. readme.txt, screenshots, banner assets, security checks, and review-team coordination. Most submissions clear review on the first or second pass.
How do you handle WordPress security?
Every form has a nonce, every action has a capability check, every database query uses $wpdb->prepare, every output is escaped (esc_html, esc_attr, esc_url, wp_kses), and every secret lives outside the codebase. Default — not optional.
Do you work with WooCommerce?
Yes — extensively. Custom payment gateways, shipping methods, subscriptions, custom product types, checkout fields, tax-compliance integrations, multi-vendor add-ons, and Indian payment-gateway integrations (Razorpay, PayU, Cashfree).
Can you build Gutenberg blocks?
Yes — React-powered block editor UX, block patterns, block variations, dynamic blocks with server-side rendering, and Full Site Editing templates. We use @wordpress/scripts and follow the modern block development model.
How do you handle plugin updates and customer support?
For public plugins: forum responses, GitHub issues, version bumps, changelog discipline. For private plugins: ticketing, custom update server (or WP.org), and patch releases on a predictable cadence.
What about multisite and translations?
Every plugin is tested on multisite installations and includes proper network-activation paths. All user-facing strings are wrapped for i18n with a generated .pot file. RTL languages are supported.
How long does a plugin take to build?
A focused custom plugin: 4-10 weeks. A repository-ready public plugin: 8-14 weeks including review prep. WooCommerce extensions: 6-12 weeks. We share milestones with weekly demos.
Do you maintain plugins long-term?
Yes — monthly retainers covering WordPress core compatibility, WooCommerce compatibility, security patches, feature releases, and customer support runbooks.
