System Integration: Connect Your Business Tools

Make your existing tools talk to each other

Sometimes the answer is not custom software. It is connecting what you already have.

Many businesses that approach us thinking they need a ground-up build actually need something simpler: their existing tools need to stop being islands. The CRM knows about the customer. The accounting system knows about the invoice. The project tool knows about the work. But none of them know about each other, so someone on your team spends their week copying information between screens.

That is not a software problem. It is a plumbing problem. And plumbing is something we are very good at.


The real cost of disconnected systems

It is worth naming the specific ways disconnected systems drain a business, because most people underestimate the cumulative cost.

Data re-entry. The same customer details, order information, or project data gets typed into two, three, sometimes four different systems. Every re-entry is a chance for error. Every error is a problem someone has to find and fix later.
Reconciliation spreadsheets. The spreadsheet that exists purely to cross-reference what is in one system against what is in another. It is updated weekly (in theory) and trusted by nobody (in practice).
Information that disagrees with itself. The CRM says the client has paid. The accounting system says they have not. Both are "right" based on when they were last updated. Finding the truth requires someone to log into both systems and compare records manually.
Invisible delays. A form submission sits in an inbox for hours because nobody saw it. A payment arrives but the order does not update. A client chases for an update you should have sent automatically.

The hours spent on this work are not dramatic. They are quiet. A few minutes here, twenty minutes there. But add them up across a team over a year and you will find a significant chunk of someone's salary being spent on work that a properly connected system would handle in milliseconds.


What we actually do

We build reliable, engineered connections between your existing SaaS tools. The goal is simple: data enters your business once and flows to every system that needs it, automatically and accurately.

In practical terms, this means:

API integrations

Direct system-to-system connections using each tool's API. When a record changes in one system, the corresponding record updates in the other. No delay, no manual step, no spreadsheet in between.

Webhook handlers

Event-driven connections that respond instantly when something happens. A payment arrives, a form is submitted, a status changes. Your systems react in real time rather than waiting for someone to notice.

Data synchronisation

Keeping records consistent across systems that were never designed to talk to each other. Bi-directional sync, conflict resolution, and audit trails so you always know which system updated what, and when.

Middleware and orchestration

For more complex workflows where data needs to flow through several systems in sequence, or where business logic determines where data goes. A custom layer that sits between your tools and makes them behave like one system.

We cover this work in detail on our API integrations and integration patterns pages, if you want the technical depth.


Common integration work

Every business has its own combination of tools, but certain patterns come up repeatedly. These are the integrations we build most often.

CRM to accounting

HubSpot to Xero. Salesforce to QuickBooks. Pipedrive to FreeAgent. When a deal closes in your CRM, the invoice should appear in your accounting system without anyone lifting a finger. Contact details, line items, payment terms: all carried across automatically.

Form submissions to CRM

Website enquiries, quote requests, and contact forms that feed directly into your CRM with the right tags, pipeline stage, and assignment. No more copying from email into your sales tool. No more leads falling through the cracks.

Project tools to invoicing

Time tracked in your project management tool flows into invoice line items. Completed milestones trigger billing. Your project status and your financial position stay in sync without reconciliation meetings.

Payment notifications to order management

Stripe, GoCardless, or your payment provider confirms a payment. Your order management system updates the status, notifies the fulfilment team, and sends the customer a confirmation. All within seconds.

These are starting points, not limits. Most modern SaaS tools expose APIs that make connection possible, though the quality and completeness of those APIs varies widely. The question is always whether the connection will be worth the investment, and we will tell you honestly if it is not.


How this differs from Zapier

You have probably heard of Zapier, Make, or similar automation platforms. They are good tools, and for simple connections between well-supported apps, they work fine. We recommend them when they are the right fit.

But there is a ceiling, and most growing businesses hit it faster than they expect.

Concern Connector platforms Engineered integration
Error handling Retry a few times, then send an email notification you might miss Custom retry logic, dead-letter queues, automatic escalation, reconciliation checks
Data validation Passes through whatever data the source system provides Validates, cleans, and maps data before it reaches the destination
Complex logic Limited to simple if/then rules and linear sequences Full business logic: conditional routing, calculations, multi-step orchestration
Monitoring Basic logs, often hard to search or alert on Real-time dashboards, alerts on failures, audit trails for compliance
When it breaks You find out when someone notices the data is wrong Automated detection, immediate notification, and often self-healing recovery

The difference matters most when integrations are business-critical. If a sync failure means a customer does not get invoiced, or an order falls through the cracks, you need engineering, not configuration. Zapier is a perfectly fine screwdriver. Sometimes you need a mechanic.


What the process looks like

Integration work follows a predictable pattern. Here is what to expect.

1

Mapping

We document every system involved, the data that needs to flow between them, and the business rules that govern that flow. This is where we find the edge cases that would otherwise surface as bugs in production.


2

API assessment

Not all APIs are created equal. Some are well-documented and reliable. Others are poorly maintained, rate-limited, or missing features you need. We assess what is possible before committing to an approach.


3

Build and test

We build the integrations, test them with real data (in a safe environment), and verify that every edge case we identified in mapping is handled correctly.


4

Deploy and monitor

We deploy the integrations, run them alongside your existing processes for a transition period, and set up monitoring so failures are caught and resolved before anyone notices.

Typically 2 to 6 weeks from start to finish, depending on the number of systems involved and the quality of their APIs. Simple two-system connections can be done in days. Complex multi-system orchestrations take longer.


Who this is for

Integration work is the right move when your tools work individually but fail as a team. Specifically:

  • You are spending hours on data entry between systems The same information gets typed into multiple tools every week. It is tedious, error-prone, and an expensive use of someone's time.
  • Your tools work, but they do not connect Each system does its job well enough. The problem is that none of them know about each other. You are the integration layer, and you should not have to be.
  • You are not ready to replace everything with custom software You like your existing tools. You just need the gaps between them closed. Integration lets you get more value from the systems you have already invested in.
  • You have outgrown Zapier or Make The connector platform worked when things were simple. Now you need error handling, complex logic, and the confidence that business-critical data flows will not quietly break.

If you are not sure whether integration or a full custom build is the better path, that is a perfectly normal starting point. We will help you figure it out during discovery.
