Integrations & APIs

Connect Your Business Systems Seamlessly

When your CRM, ERP, accounting platform, support tool, and telephony system don't talk to each other, your team becomes the integration layer.

Staff retype customer records into three systems. Finance reconciles month-end by exporting spreadsheets. Sales updates one platform and forgets the other two. The same data lives in five places, and somewhere it's already gone out of sync.

Updated 12 May 2026

Quantum Group builds the integrations that take that work off your team and put it into the connections between your systems. Real-time data flow where it matters. Reliable batch sync where it doesn't. Custom APIs and webhooks where standard connectors don't exist. The goal is operational, not architectural: your systems stop being the reason your team is slow.

Done properly, system integration removes the most expensive form of human work in most operations — moving data between tools — and produces records that are accurate everywhere, all the time. Manual transfer effort drops to near zero on integrated workflows. Customer and operational data stays current across systems. Compliance and audit work that previously required manual reconciliation becomes a side-effect of normal operations.

Common Integration Pains

Data silos that cost you customers

A customer calls your support team. The agent has no visibility on the recent sale, the open invoice, or the support ticket from last week — because each lives in a different tool. The customer explains their context for the third time this month. The integration problem isn't an IT problem; it's a customer experience problem.

Manual transfer between systems

A deal closes in your CRM. Someone creates the customer in your accounting system. Someone else sets them up in your operations platform. A third person adds them to billing. Same customer, same fields, three systems, three points of failure. The bigger the business, the more of this you're paying for.

Reports that require manual reconciliation

End-of-month reporting that requires someone to export from four systems, normalise the data, build pivot tables, and chase down the discrepancies between source systems. The discrepancies always exist, because data drifts when it's manually maintained across tools.

Stale data that drives bad decisions

Sales pipeline data that's three days old when leadership reviews it. Inventory counts that don't match what's actually on the shelf. Customer status fields that haven't been updated since the last deal. Disconnected systems produce stale data, and stale data produces decisions made on what was true last week.

Compliance and audit drag

Regulated operations require records to match across systems and to be reproducible on request. When systems aren't integrated, that consistency has to be enforced manually — slowly, expensively, and with a real risk of failing an audit.

Tool sprawl without connectivity

Most Australian SMB and mid-market businesses run between eight and fifteen SaaS platforms. Each one is reasonable individually. None of them connects to the next without help. Tool sprawl is the integration problem disguised as a procurement problem.


What We Connect

We integrate across the systems Australian businesses actually run.

CRM platforms

HubSpot, Salesforce, Pipedrive, ActiveCampaign, Zoho, Copper, Microsoft Dynamics. Two-way sync of contacts, deals, activities, and custom objects. Trigger-based workflows that fire across systems. Lead routing that picks up signals from your website, your ads, and your phones — not just from form fills.

ERP and operations platforms

NetSuite, MYOB Advanced, SAP Business One, Microsoft Dynamics 365, Cin7, Unleashed, Odoo. Order-to-cash flows, inventory sync, supplier and purchase order integration, financial consolidation. We work with both modern cloud ERP and the legacy on-premise systems many established Australian businesses still depend on.

Accounting platforms

Xero, MYOB, QuickBooks, Sage. Invoice creation from CRM-closed deals. Payment reconciliation across Stripe, Tyro, GoCardless, EFT, and direct debit. Expense and payroll integration. Multi-entity consolidation. The accounting integration is usually the highest-leverage one — it sits at the centre of most operational data flow.

Support and customer service

Zendesk, Intercom, Freshdesk, HubSpot Service, Help Scout. Unified customer view across sales and support. Ticket creation from operational events. Customer context surfaced into the support tool at the moment of contact. Integration with your knowledge base, your CRM, and your product or service systems.

Telephony and communications

Aircall, RingCentral, 3CX, Twilio, MessageMedia, ClickSend, Dialpad. Call records logged to CRM automatically. Customer context surfaced to the agent on inbound calls. Outbound dialling from CRM. SMS workflows for confirmations, reminders, and intake. Voice and messaging events available to other systems in real time.

Payments

Stripe, Tyro, Square, GoCardless, eWAY, Pin Payments, direct debit. Payment-to-invoice reconciliation in your accounting system. Subscription and recurring billing flows. Refund and dispute handling. Multi-payment-method support for businesses operating across channels.

Healthcare-specific systems

Halaxy, Cliniko, Best Practice, Medical Director, PracSuite, Coreplus, plus Medicare, DVA, and private health fund claiming. Patient record integration. Billing and claiming workflows. Clinical document handling. Healthcare integrations carry specific privacy and security obligations that we design around from day one.

Custom and legacy systems

Custom-built business applications, legacy on-premise software, line-of-business tools without modern APIs, and the bespoke databases many Australian businesses still depend on. Where no API exists, we build one. Where the existing API is incomplete, we extend it. Legacy doesn't mean unworkable.


Specific Integration Examples

A few patterns we deliver often.

HubSpot + Xero

Deals close in HubSpot. Customers, invoices, and product lines are created in Xero automatically. Payments received in Xero update the deal status and the customer record in HubSpot. Sales sees the real revenue picture. Finance stops chasing sales for invoice details. Standard pattern, high return.

ServiceNow + MYOB Advanced

Service requests in ServiceNow generate matched purchase orders, expense claims, and supplier invoicing entries in MYOB Advanced. Approval workflows trigger across both systems. Operations sees service delivery cost in real time. Finance closes the month without manually reconciling the two systems.

CRM + Telephony + Support

A single customer record exposed to sales, service, and operations regardless of which system they're working in. Inbound calls route based on CRM status. Support tickets carry the full sales history. Sales sees support issues before getting on a renewal call. Pattern works across HubSpot or Salesforce on one side, Aircall, RingCentral or 3CX on the telephony side, and Zendesk or Intercom on support.

Shopify + Cin7 + Xero

E-commerce orders flow into inventory management, fulfilment is tracked back to the order, and accounting is updated automatically — including COGS, tax handling, and multi-channel revenue split. Stock levels stay accurate across all sales channels. Finance has the data it needs without a single CSV export.

Custom application + multi-system integration

Where a custom-built operational app is the core of your business, the integration work usually radiates out from it: accounting, payments, telephony, support, and any vertical-specific tools. We design the custom app and its integrations together, so the surrounding systems are an extension of the core rather than separate islands.


API Development

When the integration you need can't be built on existing connectors, we build the connectors ourselves.

Custom APIs

REST and GraphQL APIs designed around your business data model and your security requirements. Built with proper authentication (OAuth 2.0, API keys, signed tokens), rate limiting, versioning, and comprehensive documentation. Deployed on infrastructure you own, with monitoring and audit logging from day one.

Webhooks and event-driven integration

Real-time event flow between systems where polling isn't acceptable. Order placed, ticket created, deal closed, payment received — events fire and downstream systems react inside seconds. Webhook reliability is a serious engineering problem; we build with retry, idempotency, and dead-letter handling rather than hoping the network behaves.

ETL pipelines and batch sync

For data volumes and freshness requirements where real-time isn't necessary, we build batch sync pipelines using Airbyte, custom Python ETL, or platforms like Fivetran depending on volume and complexity. Monitored, version-controlled, and recoverable.

iPaaS and integration platforms

We work with Workato, MuleSoft, Boomi, n8n, Make, and Zapier where the right answer is an integration platform rather than custom development. The decision is based on volume, complexity, cost of ownership, and whether the workflow logic is best maintained visually or in code.

Middleware and orchestration

For complex integrations involving five or more systems with branching logic, exception handling, and long-running processes, we build dedicated middleware — typically a service running on your cloud account that orchestrates the flow, handles errors, and exposes monitoring. Avoids the "spaghetti integration" pattern where every system talks to every other system directly.


How We Deliver

Every integration engagement runs through the same four-step process.

  1. 1

    Scope (Systems Audit)

    We map your current systems landscape — what tools you run, what data lives where, which systems are currently being kept in sync (and how), and where the manual work is happening. The output is a systems map, a data flow diagram showing what should connect to what, a list of integration opportunities ranked by operational return, and a recommendation on architecture. Where data ownership or quality issues exist, we surface them — most integration problems are also data problems.

  2. 2

    Design

    We design the integration architecture — real-time vs batch, point-to-point vs hub, custom code vs platform-based — based on the actual requirements rather than a default pattern. We define the data model, the failure modes, the monitoring, and the security posture. Success metrics are agreed: data accuracy, sync latency, error rate, manual effort reduced.

  3. 3

    Build

    We build with comprehensive monitoring and error handling from day one. Integrations run in a staging environment against test data before they touch production. Cutover to production is staged — typically running in parallel with the existing manual process for a defined period to verify the data flow matches expectations.

  4. 4

    Operate

    We hand over with full documentation: architecture, data flow, error handling, monitoring dashboards, and runbooks for the most likely failure modes. You choose whether Quantum Group runs the integration ongoing, whether your team takes it on, or whether we split the work. Integrations need maintenance — APIs change, business rules evolve, new exceptions appear — and the support model is decided up front. ---

Common Questions

Book a Systems Audit

A systems audit is a structured ninety-minute session with a senior member of our delivery team. We walk through your current systems landscape, identify where data is and isn't flowing properly, and produce a ranked shortlist of integration opportunities with operational return estimates and indicative build costs. You leave with a systems map, a clear view of where to start, and what a build engagement would look like. No proposal theatre, no follow-up sales sequence. ---
