Integration guide
Finance and clients joined in the background.
What connectors cover, how invoices and clients flow, realistic setup and test order, and how to handle retries and drift without losing trust.
Scope
Setup
Reliability
Support
Connectors mirror what finance already approved — they do not replace sign-off on tax, codes or customer comms.
What syncs
Invoices
Push to accounting with tax mapping
Clients
Contacts align to CRM records
Payments
Paid status + payout tracking
Portal
Client still sees same invoice state
Jobs
Quote refs map to accounting jobs
Audit
Sync logs exportable for review
Read each integration card before promising go-live dates to customers.
Document which system is “source of truth” for client name spelling before first bulk sync.
Setup order
✓Credentials stored securely · least privilege tokens
✓Chart and tax codes mapped with finance sign-off
✓Single test invoice end-to-end before bulk
✓Rollback plan if first sync conflicts
✓Sandbox tenant tested before production keys
✓Owner notified on credential rotation
Prove one happy path before turning on every document type.
