API integrations and custom development in Adelaide

If your staff are copying data between systems, exporting spreadsheets to import somewhere else, or logging into five different platforms to do one job — there's a better way. We build API integrations and custom tools that connect your business systems so data flows automatically and your team can stop wasting time on manual workarounds.

What are API integrations?

An API (Application Programming Interface) is how two software systems talk to each other. An API integration connects those systems so they share data automatically — for example, when a customer fills out a form on your website, their details land straight in your CRM without anyone retyping them. Custom development takes it further, building bespoke tools and workflows when an off-the-shelf solution doesn't exist.

What we do

System-to-system integration

Connect your CRM, accounting, booking, inventory and other platforms so data moves between them automatically.

Custom web applications

Purpose-built tools for your business — portals, dashboards, calculators or workflow apps that do exactly what you need.

Payment gateway integration

Stripe, Square, eWAY and other payment systems connected to your website or application securely.

Accounting & CRM sync

Xero, MYOB, QuickBooks, HubSpot, Salesforce — we connect the tools you already use so they work together.

Automation & workflows

Repetitive tasks automated — lead notifications, invoice generation, stock updates, report emails and more.

Third-party API connections

Need to pull data from an external service or push it to a partner's system? We build and maintain the connection.

Who it's for

Adelaide businesses running multiple software systems that don't talk to each other.
Companies wasting staff time on manual data entry and spreadsheet exports.
Organisations needing a custom tool that no off-the-shelf product provides.
E-commerce businesses that want their website, stock, accounting and shipping to sync automatically.

How it works

We map your current workflow. A look at your systems, where data lives, what's manual and what's causing headaches.
We design the integration. A clear plan showing what connects to what, how data flows and what gets automated.
Build and test. We develop the integration or custom tool, testing thoroughly with real data before anything goes live.
Deploy and monitor. The integration goes live and we monitor it to make sure everything syncs correctly.
Ongoing support. APIs change, systems update — we maintain the connection so it keeps working as your tools evolve.

API integration questions

What systems can you integrate?

If it has an API, we can connect it. We've worked with Xero, MYOB, Salesforce, HubSpot, Stripe, Square, ServiceM8, simPRO, Microsoft 365 and many more. If you're not sure, just ask — we'll tell you what's possible.

How long does an integration take?

Simple integrations can be done in a week or two. More complex multi-system builds typically take four to eight weeks. We'll give you a clear timeline upfront.

What happens if an API changes?

APIs do get updated from time to time. With an ongoing support arrangement, we monitor your integrations and update them when the connected services change.

Can you fix an integration someone else built?

Usually, yes. We can audit what's there, identify what's broken and either fix it or rebuild it properly.
