At a glance. Define when data is approved to move, which system owns it and what happens on failure. The integration should reduce copying while preserving financial controls.
Integration connects the tools you already use
Sales records live in the CRM. Invoice and accounting records live in finance systems. When a person copies names, amounts and payment terms between them, the business spends time on a task that can often be structured as an integration.
The objective is to move agreed data between reliable sources. It does not require replacing every system with a single platform, and it does not remove financial review or approval.
Three practical workflows to assess
| Workflow | Trigger | Controls to include |
|---|---|---|
| Enquiry → CRM → owner or calendar | An accepted form or service enquiry. | Deduplication, source tracking, assignment and appropriate confirmation. |
| Approved order → invoice draft → accounting | An order or contract reaches the agreed approved stage. | Customer details, amounts, tax treatment, terms and approval before issue. |
| E-commerce → stock → shipping | An accepted online order. | Stock checks, cancellations, returns, tracking and failed fulfilment. |
Do not assume that every “won” CRM deal should immediately issue an invoice. Define the business event that authorises billing and the person responsible for exceptions.
Map the records before building
- Customer identity: decide which stable identifier joins records; a display name alone is rarely sufficient.
- Source of truth: specify where company details, order amounts and payment terms are maintained.
- Tax and invoice fields: have the responsible finance team approve the mapping for each relevant situation.
- Duplicate prevention: ensure a repeated event cannot create the same invoice twice.
- Traceability: retain the order ID, source and processing status.
Make, Zapier or custom integration?
A visual automation tool can be useful when the required connectors, API access and control flow are available. Make can organise branching scenarios and data transformations; Zapier can be practical for straightforward app-to-app actions. Check the actual integration capabilities for your software and subscription plans.
Custom development may be justified by specialised logic, security requirements, high throughput or legacy systems. Choose it because those requirements warrant it, rather than assuming code is automatically more reliable.
Design the failure path
- Validate required fields before creating a record.
- Route incomplete or conflicting data to a person.
- Retry only when it is safe and avoid duplicate actions.
- Alert an owner when an execution fails.
- Keep logs that connect the original event to the final record.
- Document recovery and reconciliation steps.
Estimate the whole project
Platform subscriptions are only one cost. Include process mapping, connector configuration, data cleanup, testing, documentation and monitoring. Current usage limits and billing units differ by provider, so price the expected workload rather than relying on an old plan comparison.
Test a representative set of normal and exceptional cases with finance and sales before production. Start with one manageable flow, then expand once the records reconcile and the team can recover from failures.
Frequently asked questions
Can we do this without a developer?
Often, when supported connectors or accessible APIs cover the workflow. API restrictions, legacy software and specialised security or business rules can require technical development.
What happens when we change CRM?
A documented mapping and stable record identifiers make migration easier. The replacement connector and its behaviour still need testing; it is not necessarily a one-click change.
Can the workflow support electronic invoicing?
It can connect to an invoicing system that supports the required process. The finance owner should validate document fields, issue status and any required exchange or delivery acknowledgements.
