API Integration Services & Custom API Development
Your team spends hours copying data between systems. Invoices, contacts, stock levels, timesheets. Entered once, then entered again. We build the integrations that stop the double-handling.
Custom API integration services connecting MYOB, Xero, Shopify, Salesforce, HubSpot, simPRO, and hundreds more. We also design and build custom APIs for internal systems, partner data exchange and legacy platforms that need a modern interface.

Custom API Integration and API Builds That Actually Work
Most businesses run on five to ten different platforms. Accounting, CRM, job management, eCommerce, inventory, payroll, reporting. All doing their job individually. The problem is they do not talk to each other, so your team fills the gaps manually.
Our API integration services connect those platforms. We build custom integrations between systems like MYOB, Xero, Shopify, Salesforce, HubSpot, simPRO, and hundreds of other tools Australian businesses rely on. Standard API connections for platforms that support them. Custom integration solutions (database-level, file-based, or middleware) for systems that have no ready-made connector.
And when the real need is a <strong>custom API</strong>, not just a connector, we build that too. Internal system APIs, partner APIs, webhook endpoints, middleware layers and secure service interfaces that let your software exchange data reliably.
The result is simple: data enters a system once and flows where it needs to go. No re-keying, no spreadsheet imports, no waiting on someone to manually process something that should have happened automatically.
Choose the right integration path
Need a custom API built as part of the project?
Some integration projects need more than field mapping between two tools. They need a secure API layer, webhook handling or a modern service interface in front of an internal system.
Need a custom API, not just an integration?
Some projects are not about syncing two SaaS tools. They need a custom API so your internal system, customer portal, mobile app or partner platform can exchange data reliably.
We design and build REST APIs, integration endpoints and secure service layers that expose the right data, enforce the right rules and fit the systems around them.
Explore API development →Expose old systems through a modern interface
If your core data lives in SQL Server, Access, a desktop app or a custom internal database, we can place an API layer in front of it so newer systems can connect cleanly.
That lets you modernise incrementally instead of ripping out a business-critical system all at once.
See legacy integration options →Build reliable event-driven data flows
Webhook listeners, retries, queues, idempotency, validation, rate limits and audit logging. We build the plumbing that keeps API integrations stable after launch.
This is where most DIY integrations break. We design for production reliability from the start.
See monitoring approach →Maintain APIs after they go live
APIs change. Authentication expires. Field mappings drift. We plan for versioning, monitoring and support so the integration keeps working when upstream platforms move.
That matters for partner APIs, customer-facing APIs and any integration your operations rely on daily.
Scope an API project →How we connect business systems
Not every integration is the same. Some platforms have clean APIs. Others have databases, flat files, or nothing at all. Here are the methods we use.
API integrations
Connect platforms that offer modern APIs: accounting software, CRMs, eCommerce stores, payroll systems. We build reliable two-way sync that runs without you thinking about it.
Database integrations
SQL Server, MySQL, PostgreSQL. We connect directly to your databases when API access is not available or not practical. Secure, scheduled, auditable.
Excel and CSV workflows
Replace manual imports and exports with automated file processing. Upload, validate, transform and push data into the right system. No more spreadsheet gymnastics.
Access and legacy systems
Old desktop apps, Access databases, flat files. They still hold critical data. We extract, transform and route that data into modern platforms without ripping out what works.
Custom middleware
When there is no off-the-shelf connector, we build one. Custom transformation logic, field mapping, validation rules and error handling. All specific to your workflow.
Real-time and scheduled sync
Some data needs to move instantly. Other data syncs daily. We match the frequency to your business requirements so nothing gets stale and nothing gets overwhelmed.

API Integration Specialists
Tell us what systems you need connected
Book a scoping call and we will map out the integration or API build, give you a fixed-price quote, and explain exactly what is involved. Plain English, no jargon.
Need a custom integration? We build those too
Not every system has a nice API with documentation and a Zapier connector. Some of the most valuable integrations involve platforms that nobody else will touch.
Systems without an API
Not every system was built with integration in mind. Some older platforms have no API at all. Just a database, a file export, or a screen full of data that someone copies into a spreadsheet every day.
We reverse-engineer the data flow. We connect at the database level, automate file-based imports, or build custom middleware to get data moving. If the data exists, we can usually reach it.
Old desktop systems and Access databases
Access databases, VB6 tools, FoxPro, even custom-built desktop apps from the early 2000s. We have seen them all. And the data trapped inside them is usually still business-critical.
We extract and transform that data into modern systems. Or if you are not ready to replace the old system, we set up a sync layer so the legacy app keeps running while new systems consume the same data.
Excel-driven business processes
Some businesses run entire workflows in Excel. Price lists, stock levels, timesheets, customer records, all managed in spreadsheets that someone emails around or drops into a shared drive.
We replace that with automated ingestion. Files get picked up, validated, transformed, and pushed into the right systems. No more manual copy-paste. No more broken formulas. No more "which version is the latest".
Custom portals and internal tools
Your team might be running an internal web app, a custom-built CRM, or a portal that was developed years ago. These systems hold valuable data but they do not talk to anything else.
We build integration layers (APIs, webhook listeners, scheduled sync jobs) so your internal tools feed data to and from your accounting, CRM, and operational platforms automatically.
Clean data in. Clean data out.
Moving data between systems is only useful if the data is correct. We build validation, deduplication and exception handling into every integration. Not as an afterthought.
Duplicate prevention
Matching rules catch duplicates before they land. Contacts, invoices, products. We stop the doubles at the door instead of cleaning them up later.
Field validation
Every record gets checked against your rules: required fields, formats, ranges, business logic. Bad data gets flagged, not pushed through.
Mapping and transformation
Field names, formats and structures differ between systems. We build the translation layer that converts data from one system into exactly what the other expects.
Failed record handling
When a record fails to sync, it does not disappear. It gets logged, flagged and queued for review. Your team knows what failed, why, and what to do about it.
Historical data cleanup
Bad data already in the system? We run cleanup and deduplication processes to fix what is there before connecting it to something else. Clean start, clean ongoing.
Cross-system consistency
One source of truth, enforced. When a contact updates in your CRM, it updates in your accounting system. When a price changes, it flows everywhere it needs to.
Integration monitoring and alert dashboards
Integrations are not set-and-forget. We build monitoring and alerting so you know everything is running. And when it is not, you find out first.
See every integration at a glance
A single dashboard shows the status of all your integrations: what is running, what has failed, when the last sync happened, and how many records moved.
Green means healthy. Red means something needs attention. You do not have to dig through logs or ask someone to check.
Know about problems before they compound
When a sync fails, whether it is a network timeout, a validation error, or a rate limit, the system alerts your team immediately.
Failed records get queued for retry or manual review. Nothing gets silently dropped.
Full visibility on every record that moves
Every sync job is logged with timestamps, record counts, success rates and errors. When your accountant asks "when did that invoice come through?" you have the answer.
Audit trails support compliance requirements and give you confidence that data integrity is maintained across all connected systems.
Handle edge cases without losing data
Not every record fits neatly. Some need manual review: mismatched accounts, duplicate contacts, incomplete records.
Exception workflows route these to the right person with context, so they can resolve them quickly without digging through raw data.

Common questions about integration projects
Can you connect systems that were custom-built for our business?
Yes. If the system stores data (whether in a database, via an API, or even in files) we can almost always build an integration. We have connected custom CRMs, bespoke ERPs, internal portals and industry-specific platforms that no connector platform supports.
Can you build a custom API for our software or internal system?
Yes. We build custom APIs for internal systems, customer portals, partner integrations and legacy platforms that need a modern interface. That can include endpoint design, authentication, validation, webhook handling, versioning and monitoring.
What if the system we use does not have an API?
We work with what is available. That might mean connecting directly to the database, processing file exports on a schedule, or building a middleware layer to extract and transform the data. No API does not mean no integration.
Can you integrate databases directly?
Yes. SQL Server, MySQL, PostgreSQL, and even older systems like Access. Direct database integration is common for legacy systems, internal tools, and situations where the API is too limited for what you need.
Can you work with Excel and Access files?
Absolutely. We automate the ingestion, validation and processing of Excel, CSV and Access files. Data gets extracted, cleaned and pushed into your target systems automatically. No more manual imports or copy-paste.
How do you prevent duplicate data between systems?
We build matching rules into every integration. Before a record is created, the system checks for existing matches based on configurable criteria: email address, invoice number, company name, or whatever makes sense for the data type. Duplicates get flagged or merged, not created twice.
Do you monitor integrations after they go live?
Yes. Every integration we build includes monitoring and alerting. We track sync health, detect failures, log every transaction, and alert you when something needs attention. We also offer ongoing support agreements for teams that want us handling issues directly.
How much do integration projects typically cost?
It depends on the complexity. A straightforward two-system API sync might start from $5,000. Multi-system integrations with custom logic, data transformation and monitoring dashboards typically range from $10,000 to $40,000. We give you a fixed-price quote after a scoping session. No surprises.
Do you only work with businesses in Perth?
We are based in Perth but work with businesses across Australia. Most of our integration work is done remotely. We scope via video call, build and test in staging environments, and go live with you on the line. Location is rarely a barrier.
