Stop your staff retyping the same customer twice. Plan the integration properly.
How to plan business software integration, including what happens when it fails and who's responsible.
The short answer
Business software integration connects two or more existing systems, such as a CRM and an accounting package, so information passes between them automatically instead of being retyped. Good planning means mapping exactly what data moves, in which direction, what happens when it fails, and who is responsible for fixing it.

What business software integration actually solves
Most integration requests come from staff retyping the same information twice: a new customer added to a CRM also needs adding to accounting software, or a completed job needs invoicing automatically. Integration removes that duplicate work and the errors it causes.
Check compatibility before planning the build
Not every pairing of tools can be connected simply. Some products offer a proper API and existing connectors (for example through Zapier or Make); others only allow manual CSV export. Confirm what's technically possible before agreeing a scope or a price.
No-code connector
- — Simple, low-volume transfers
- — Monthly cost scales with volume
Custom integration
- — Handles unusual rules or high volume
- — Needs ongoing monitoring
Questions to answer before building an integration
- Which system is the 'source of truth' for each piece of data?
- Does data need to flow one way, or both ways?
- How often does it need to sync: instantly, hourly, or once a day?
- What happens if a record fails to transfer? Who sees that failure?
- What happens to duplicate or conflicting records?
“Map the exact data fields that need to move, not just 'connect the systems'.”
Ready-made connector vs custom integration
| Option | Good for | Watch out for |
|---|---|---|
| Built-in integration (native) | Popular tool pairings | May be limited in what fields it syncs |
| No-code connector (Zapier, Make) | Simple, low-volume transfers | Monthly cost scales with volume |
| Custom integration | Unusual rules or high volume | Needs ongoing maintenance and monitoring |
Realistic costs and risks
A simple no-code connector might cost very little beyond a monthly subscription. A custom integration with error handling and monitoring is a proper software project, typically running into the low thousands of pounds depending on complexity, plus ongoing hosting and support.
Always test with real but anonymised sample data before relying on an integration for live customer records.
Who owns an integration after it's built
Integrations quietly break when one of the connected systems updates its software. Agree who is responsible for monitoring this, whether that's your developer, an in-house staff member, or the no-code platform's support team, before you rely on it for anything important.
Keep a simple written record of every integration you run: what it connects, what it moves, and who to contact if it stops working. This saves confusion when staff change.

Your questions
- What is business software integration?
- It's connecting two or more systems, such as a CRM, accounting package or booking tool, so data moves between them automatically rather than being manually re-entered.
- How much does software integration cost?
- A simple no-code connector can cost little beyond a monthly subscription. Custom integrations with error handling typically run into the low thousands of pounds, depending on complexity.
- Can any two systems be integrated?
- No. It depends on whether each system offers an API or connector. Check compatibility before planning a budget or timeline.
- What happens if an integration fails silently?
- This is a real risk. Always plan for visible error alerts and a manual fallback, so a failed transfer doesn't go unnoticed.
