WordPress Custom Development
If it doesn’t exist out of the box, we’ll build it.
Sometimes plugins aren’t enough. Your business might need custom functionality, unique workflows, or advanced integrations to keep things running smoothly. That’s where we come in. At WP Expert, we design and build tailored WordPress solutions that make your website work exactly the way your business needs it to.
We fully understand business processes and efficiency. Beyond building features, we help you digitise your workflows and implement automation to save time, reduce errors, and boost productivity.
Why WordPress Custom Development matters
Off-the-shelf plugins only go so far. They’re built to cover as many scenarios as possible, which often makes them heavy, complex, and slower than they need to be. Too many bulky plugins can hurt performance, introduce conflicts, and create security risks.

FAQs
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 are designed to cover every possible scenario. That makes them heavy, complex, and often slower than they need to be. Custom development avoids this bloat, giving you lean, efficient functionality that won’t hurt performance or security.
What is WordPress API integration?
API integration connects your WordPress site with other systems so they can share data automatically. For example, orders from your website can flow into Xero, leads from forms can go into Salesforce, or bookings can sync with your scheduling system.
Can you build custom API endpoints?
Yes. We don’t just connect WordPress to other systems — we can also create custom endpoints so your external systems can push or pull data from your website. For example, products can automatically be published 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. We use secure authentication, encryption, and controlled access to ensure data stays protected. Every integration is thoroughly tested for reliability and safety.
How much does custom development cost?
Since every project is different, pricing depends on the complexity and scope. Some integrations are simple, while others require building custom workflows or endpoints. We’ll 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?
Once development is finished, we’ll hand everything over to you with clear documentation. If you’d like ongoing improvements or support, you can add one of our Support packages for continuous help with updates, content, or technical issues.
