Software Co builds custom API and systems integrations for Australian businesses, connecting accounting platforms like Xero and MYOB, payroll, payments, CRMs, ERPs and health or government services. We map which system owns which data first, then build with retries, alerts and monitoring so failures are caught early. Our teams work from Sydney and Melbourne and serve clients Australia wide.
Key 2026 Australian Integration Regulatory & API Pricing Updates
Three changes in the last few months are good reasons to look at how your systems talk to each other.
Payday Super: From 1 July 2026, employers move to paying super guarantee in line with payday instead of quarterly, and the ATO’s Small Business Superannuation Clearing House closed permanently on that date. Any custom pay run, timesheet or HR sync that feeds super calculations is worth checking.
Xero API pricing: Xero introduced tiered developer pricing from 2 March 2026. The Starter tier is free with five connections; paid tiers add monthly fees, connection limits and data allowances, and the higher tiers require app certification. How this affects you depends on how your integration connects.
E-invoicing: Commonwealth agencies and their suppliers are being moved onto the Peppol e-invoicing network, with deadlines reported for mid and late 2026. Private businesses are not generally mandated, though adoption is encouraged.
Why Australian Enterprises Partner With Software Co for API Integration
We map before we code
Every project starts with an Integration Map: which system owns which data, which direction it flows and what happens on conflict. Most integration problems are data ownership problems in disguise.
We design for failure
APIs go down, rate limits kick in and vendors change terms. We build retries, duplicate protection, alerts and a failure playbook as standard, not as extras.
Real Australian integrations, from health to finance
Our case studies include Medicare and My Health Record connections, Stripe and Tyro Health payments, and credential checks with AMC and AHPRA. We describe only what those case studies show.
You own what we build
We aim to run integrations in your accounts, with your credentials, and hand over documentation so you are never locked in.

Integration Pattern Selection Framework
The right answer is often the cheapest one that works. Here is how we think about it.
Our 6-Step API & Systems Integration Lifecycle
Systems & Data Map
We list every system involved, which one is the source of truth for each type of data, and who is affected when it is wrong. The output is a one-page Integration Map, so everyone agrees on what syncs, in which direction and how often.
Pick the Right Pattern
Native connector, an integration platform, custom code or an event-driven design. We choose on cost, volume, control and how often the systems change, and we will recommend the cheaper option when it fits.
Sandbox & Contract Tests
We build against vendor test environments and write tests for the shape of the data each system sends and expects, so a change on their side is caught before it reaches your customers.
Build With Failure Handling
Retries, queues, duplicate protection, rate-limit handling, alerts and logging are built in from the start. We also write the failure playbook: what breaks, who is told and what to do.
Parallel Run & Reconcile
The integration runs alongside your existing process while we compare the results record by record. Differences are explained and fixed before anything is switched over.
Launch, Monitor & Hand Over
We release in stages, watch the dashboards and alerts, and hand over documentation, credentials and access. Integrations rely on other people's software, so we agree how changes will be monitored and handled.

Frequently Asked Questions
Do I need custom integration, or will a native connector or Zapier do?
No, not always. If both systems offer a maintained connector that moves the fields you need, use it. Custom integration earns its cost when you need two-way sync, business rules, several systems in one flow, volumes, a connector throttles, or an audit trail. We will tell you at the start if an existing connector is enough.
What does Payday Super mean for my payroll and accounting integrations?
Xero changed its API pricing in 2026. Does that affect an integration?
