FAQ

Questions we
often hear.

What is custom WordPress development?

Custom WordPress development means building features, workflows, or integrations that standard themes or plugins can’t provide. Instead of relying on bulky plugins, we create lightweight, tailored solutions that deliver exactly what your business needs.

Why not just use plugins instead of custom development?

Plugins are great for common needs, but many cover every possible scenario: heavy, complex, slow. Custom development gives you lean, efficient functionality that won’t hurt performance or security.

What is WordPress API integration?

It connects your site with other systems so they share data automatically: orders into Xero, form leads into Salesforce, bookings synced with your scheduling system.

Can you build custom API endpoints?

Yes. External systems can push or pull data from your website. For example, products publish automatically once they pass QA in your production line.

What types of systems can you integrate with WordPress?

We work with a wide range of platforms, including CRMs (Salesforce, HubSpot, Keap), payment gateways (Windcave, Paystation, Stripe, PayPal), accounting tools (Xero, MYOB), booking systems (Calendly, Eventbrite), marketing platforms (Mailchimp, ActiveCampaign), and custom proprietary systems.

How does custom development help with process efficiency?

We don’t just code features. We help you digitise workflows and automate repetitive tasks. That means less manual work, fewer errors, and more productive use of your time. From financial automation to manufacturing integrations, we make your website part of your business process.

Is API integration safe?

Yes. Secure authentication, encryption, and controlled access keep data protected. Every integration is thoroughly tested.

How much does custom development cost?

It depends on complexity and scope. We provide a clear, project-based quote before starting, so there are no surprises.

Do you only work with New Zealand systems?

No. While we have strong expertise with local platforms like Windcave, Paystation, and Xero, we also integrate with global platforms like Stripe, Salesforce, and HubSpot. Whether your tools are local or international, we can connect them with WordPress.

What happens after the project is complete?

We hand everything over with clear documentation. Add a Support package for ongoing improvements and help.
