FAQ

Custom Plugin FAQs

When should I choose custom plugin development over an existing plugin?▼
Choose custom when no existing plugin fits your workflow, you need unique functionality, or you want full control over code and updates. We assess whether an existing plugin + customization is better or if building from scratch makes sense.
Do you build Gutenberg blocks?▼
Yes. We build custom blocks using React and the Block Editor API. Blocks can include server-side rendering, block patterns, and integration with your theme's theme.json. We also build block-based page builders when needed.
Can you extend WooCommerce?▼
Yes. We build custom payment gateways, shipping methods, product types, checkout customizations, and admin extensions. We follow WooCommerce extension standards for compatibility and updates.
Do you support multisite?▼
Yes. We build plugins that work across WordPress multisite—network activation, site-specific settings, and cross-site functionality. We handle the complexity of multisite data and permissions.
