Klaviyo integrationOur process
How an integration project runs
Every integration follows the same four steps. You sign off on each one before we move to the next, so there are no surprises in scope, timing or cost.
01
Scope
We take the time to understand your systems, your data and the way your team actually works. We map every field that needs to move, which system owns it, and what should happen when the data disagrees.
02
Proposal
You get a plain-English plan with milestones and release cycles, so you know what you’re getting, how much it’s costing and when to expect it. If an off-the-shelf connector would do the job, we’ll tell you.
03
Development
We build and test against your real systems, milestone by milestone. Your dedicated project manager keeps things moving, and nothing changes without your approval.
04
Release
We go live with documentation, training and logging in place, then monitor the integration and keep it running as the systems around it change.
Everything else
Other systems we connect
Beyond the platforms above, these are the systems we connect regularly, so information is entered once and is right everywhere.
CRM & sales
HubSpot, Salesforce, Pipedrive and Zoho.
Accounting & ERP
Xero, MYOB, NetSuite and Microsoft Dynamics 365 Business Central.
Ecommerce, POS & inventory
Shopify, WooCommerce, WordPress, Square and Lightspeed.
Marketing
Klaviyo, HubSpot Marketing Hub and your website forms.
Bookings & practice management
Nookal, Cliniko, Calendly and Microsoft Bookings.
Jobs & field service
ServiceM8, simPRO, Tradify and AroFlo.
Rostering & timesheets

Data & no-code tools

Legacy, EDI & CSV
EDI, scheduled CSV feeds, SFTP file drops and direct database connections.
Webhooks & custom APIs
Real-time events from your providers, and APIs built for systems that don’t have one.
Don’t see your system? If it has an API, an export or a database, we can almost certainly connect it. We’ll confirm the specifics during scoping.
Connector or custom?
Off-the-shelf connector vs custom integration
Tools like Zapier and the built-in integrations in your software are a great place to start. They stop being the right answer when the data matters, the volume grows or your process doesn’t match the template.
Off-the-shelf
Connectors and built-in integrations
Quick to switch on and fine for simple jobs, such as sending a new form entry to your CRM.
- Fast to set up for common, one-way syncs
- Pricing usually grows with every task or record
- Limited room for your own business rules
- Can fail quietly when a field or plan changes
- Error handling and logging are basic
Custom
A custom integration built for your workflow
Built around your real data and rules, for the integrations your business depends on.
- Handles your business rules, mappings and exceptions
- Two-way sync with retries, logging and alerts
- Runs on your hosting or ours, without per-task fees
- Monitored and maintained as connected systems change
- You own the code from day one
Not sure which you need? We’ll tell you honestly. If an off-the-shelf connector will do the job, we’ll say so and help you set it up properly.
Pricing
How we price integration work
No hourly billing and no surprise invoices. You know what you’re building, and roughly what it will cost, before development starts.

Code Squirrel were fantastic from the minute we engaged with them until the project was delivered. Code Squirrel scoped out the works, provided an awesome quote and delivered the software setup on our server within a couple of weeks.”
FAQ
System integration questions, answered
What is system integration?
It’s connecting your business software so that data entered in one system appears automatically everywhere it’s needed. Most integrations use each system’s API to move data in real time or on a schedule. If APIs are new to you, start with What is an API? Add AI to the steps in between and you have AI workflow automation.
Which systems can you integrate?
Most of them. We regularly connect CRMs, accounting and ERP systems, e-commerce platforms, freight platforms, practice management software and databases, including Xero, HubSpot, Shopify, Business Central, MachShip, Airtable and Nookal. If a system has an API, an export or a database, we can almost certainly connect it. See all the platforms we integrate.
Do you build custom integrations or use tools like Zapier?
Whichever is right for the job. Off-the-shelf connectors suit simple, low-volume syncs. Custom integrations suit work your business depends on, where you need your own rules, two-way sync, error handling and no per-task fees. We’ll recommend the simplest option that works.
How much does a system integration cost?
The first consultation is free. Scope and design is a fixed price from $1,200 ex. GST, and you get an estimate for the build before development starts. The build itself is quoted and delivered milestone by milestone, with nothing changing without your approval.
How long does an integration take?
It depends on how many systems and rules are involved. A simple one-way sync can be live in days. Larger projects are delivered in milestones, and our typical time to a first release is around four weeks.
What if one of our systems doesn’t have an API?
We can still usually connect it. Options include EDI, scheduled CSV or spreadsheet imports and exports, SFTP file drops, direct database connections, or building a small API in front of the legacy system.
Is our data secure?
Integrations use the minimum access each system allows, credentials are stored securely, and every sync is logged. We can host the integration in Australia or on your own infrastructure, and a mutual NDA is offered up front on every engagement.
What happens when one of the connected systems changes?
Software updates and plan changes are the most common reason integrations break. We build in logging and alerts so problems are caught early, and we can monitor and maintain the integration month to month after launch.
Who owns the integration?
You do. Source code, hosting and data sit in your name from day one, so there’s no lock-in.
Can you integrate Nookal with our other systems?
Yes. We’re a Nookal N.I.C.E. List Partner and build custom Nookal integrations, reports and automations. See Nookal integration for details.
Can AI help with our integrations?
Yes. Once your systems are connected, AI agents can act on that data, for example answering enquiries, updating records or routing jobs across the platforms above.
