Most businesses don't run on one system. They run on a CRM, an accounting package, a booking tool, a payment gateway, a spreadsheet someone updates by hand, and three logins nobody documented. When those pieces don't talk to each other, your team becomes the integration — copying data across, chasing errors, and doing work software should be doing.
Core Creations builds the connections and the tooling in between. We integrate the platforms you already use through their APIs, automate the handoffs, and where an off-the-shelf tool doesn't exist, we build a lean custom one. It's a real Sydney team writing real code you own — not a black-box plugin or an offshore ticket queue.
What an API integration actually involves
An API is the doorway one piece of software offers to another. Integration is the work of connecting those doorways reliably: mapping the fields, handling authentication, deciding what triggers what, and making sure it keeps running when data is messy or a service is briefly down. Done properly it's invisible to your team. Done cheaply it breaks quietly and you find out from an angry customer.
Typical work we take on includes:
- Syncing customers, orders or invoices between two systems (for example CRM to accounting)
- Pushing form and enquiry data straight into the tools your team lives in
- Connecting payment, booking, shipping or SMS providers
- Scheduled jobs that move or clean data on a timer
- Error handling and alerts so a failed sync doesn't disappear silently
What Core Creations delivers
We start by mapping how data actually moves through your business today, then scope the smallest build that fixes the real bottleneck. You get a fixed quote before we write a line of code, documentation of what we built and why, and code that lives in your accounts and repositories — not ours.
Here's what we won't do: we won't bolt on a fragile no-code chain and call it robust, we won't build something only we can maintain to keep you dependent, and we won't recommend a custom tool when an existing product already does the job better and cheaper. If the honest answer is "just use this integration that already exists," we'll tell you.
Custom internal tooling
Sometimes the problem isn't connecting two apps — it's that the tool your team needs doesn't exist. A quoting calculator, an internal dashboard that pulls from several systems, an admin panel to manage something a spreadsheet has outgrown, or a small workflow app for a process that's unique to you.
We build these lean and purpose-built, focused on the one job they need to do well. No bloated platform, no per-seat licence creeping up every year, no features you'll never touch. Just a tool that fits how your team actually works and can grow when you do.
How we work
Every engagement starts with a scoping conversation, usually free, where we work out whether an integration is even the right answer. From there you get a fixed, itemised quote — you approve it before anything begins, so there's no open-ended hourly meter running.
We build in stages you can see, test against your real data, and hand over with documentation. We're based in Chatswood and work with clients across Australia. Timelines depend on scope — build your quote for a tailored estimate — but a focused single integration is usually a matter of weeks, not months.

How much does an API integration cost?
It depends on how many systems are involved and how clean their APIs are — a single straightforward connection is very different from syncing four systems with messy data. We give you a fixed, itemised quote after a short scoping call so you know the number before committing — build your quote for a tailored estimate.
How long does it take?
A focused single integration is usually a matter of weeks; larger multi-system builds or custom tools take longer. We'll give you a realistic timeline with your quote rather than an optimistic guess.
Do I own the code you build?
Yes. The code lives in your accounts and repositories, with documentation, so you're never locked to us. If you ever want another developer to take over, they can. We build to be handed over, not to trap you.
Is there a lock-in contract?
No. Integration and tooling projects are quoted as fixed-scope work. If you want ongoing support or maintenance afterwards that's optional and separate — you're never signed into a contract you can't leave.
What happens if an API changes or a sync breaks?
We build in error handling and alerts so failures surface instead of vanishing quietly. APIs do change over time, so we can arrange optional ongoing maintenance, or hand over clear documentation so your own team can manage it.
Do you only work with Sydney businesses?
We're based in Chatswood in Sydney, but integration work is done remotely, so we work with clients right across Australia. A local team, no offshore outsourcing, one point of accountability wherever you are.
