Test the connector against your actual process
A product listing that says ‘CRM integration’ does not establish that it supports your custom fields or approval steps. Write down one complete handoff and test it using synthetic records.
Check the direction of updates. A connector that creates a contact may not update a project, handle deleted records, or distinguish a new engagement from an existing one.
Look past the successful first run
Compare how each option deals with changes and failures. Native configuration can be the simpler, more maintainable choice when it covers the process. A custom build may be justified when the gap is explicit and important.
- Fields and events: are the required data and triggers available on your current plan?
- Access: can the integration run with the permissions it actually needs?
- Failure handling: can your team see and reconcile an uncertain result?
- Volume: what limits or usage charges apply?
- Ownership: who maintains mappings when a field or API changes?
Custom code is not a way to escape every dependency
A custom connector still depends on vendor APIs, credentials, and deployment infrastructure. It may need changes when a provider changes its contract.
Ask for those dependencies to be named in the proposal. Separate implementation, licenses, hosting, and ongoing support rather than comparing only the initial development fee with a software subscription.
Choose the smallest change that covers the gap
Sometimes the answer is configuration inside a tool you already use. Sometimes a short workflow on an automation platform is enough. Sometimes a dedicated service is needed to validate records, apply permissions, and coordinate several writes.
The useful question is not ‘Which option is more advanced?’ It is ‘Which option meets the agreed requirements, and can our team operate it afterward?’
