Custom Node.js API Development
Power your digital tools with secure and fast backends. We build custom server logic and clear APIs. This ensures your apps run perfectly and stay reliable over time.
Secure, High-Performance Server-Side Logic
Power your digital tools with secure, fast backends. Tasman Tech builds custom Node.js APIs and organised server logic. We test everything to make sure data stays in sync and works perfectly. Our focus on quality gives you strong apps you can always rely on.
Custom Node.js Development
We use Node.js and the NestJS framework to build fast and secure server applications. Our custom apps are made to handle complex tasks and run smoothly for your business.
REST API Architecture & Integrations
Easily connect your React front-end apps to outside systems. We design clear REST APIs that keep your data in sync and ensure your systems run without any issues.
Sandbox & Production Environments
We build strict test and live systems to make sure data is always correct before it goes live. This approach keeps your apps safe and secure as they grow.
Automated Testing & CI/CD Pipelines
We focus heavily on quality and use tools like Jest to test everything. Our smooth GitHub Actions setup launches your app quickly, reducing wait times and keeping your system safe.
Connect Your Online Shop, POS and Xero
Most small businesses run on a handful of systems that don't talk to each other. Someone ends up copying online orders into Xero, or retyping in-store sales so the website stock is right. We write Node.js integrations that do that copying for you.
- Shopify or WooCommerce to Xero. Each online order becomes a Xero invoice, with the right GST and account codes.
- POS integrations. In-store sales flow through to your website, so you don't sell the same item twice.
- Courier labels. A paid order creates the courier booking and label, ready to print at the packing bench.
- Reporting dashboards. Sales, stock and orders on one screen, built as custom React dashboards.
- Small automations. Order alerts or follow-up emails can run as simple n8n workflows.
We Work With the Systems You Already Have
Plenty of businesses already have something in place. An ordering portal a developer built years ago. A POS system the staff know well. A spreadsheet that quietly runs the warehouse. You don't need to throw any of it away.
We start by learning how your current setup works and where the double handling happens. Then we build the missing link, using each system's API where there is one (see our API integration page) and careful data imports where there isn't. Your team keeps the tools they know, and the retyping stops.
The same team also builds WordPress websites and custom web design, so your site and its back end are planned together rather than patched together later.
Stock Sync and Trade Portals That Keep Up
When you sell in-store, online and to trade customers, stock numbers drift. A product sells out on the shop floor but still shows as available online. A stock sync fixes that by updating every channel from one source.
- Warehouse stock counts update your online store automatically.
- Trade and wholesale customers log in to their own portal, see their pricing and place orders.
- Trade orders land in your system ready to pick, pack and invoice through Xero.
- Low-stock alerts reach the right person before a best seller runs out.
We cover every integration with automated tests, so a change at one end doesn't quietly break the other. After launch, we can look after it as part of our ongoing website management.

Start With One Connection
Integration work can feel like a huge project. It doesn't have to be. We usually start with the job that wastes the most time each week, like getting online orders into Xero. Once that runs well, we add the next piece.
It starts with a free chat. Then you get a fixed written quote for each phase, so you know the cost before any work begins. You own all the code we write, and you deal with a local team in your time zone.
