List every event that should create or update financial records: a CRM deal moving to “Closed Won,” a checkout in Stripe, a signed proposal, an email with an attached purchase order, or a bank feed update. Each trigger should be unambiguous, timestamped, and reliably reproducible, minimizing ambiguity and protecting downstream steps from noisy or incomplete inputs.
Name fields consistently across tools, choose a universal customer identifier, and decide how line items, taxes, and discounts will be represented. Aim for formats that remain intact during conversions, like structured JSON payloads or normalized tables. This approach makes transformations predictable, reduces manual corrections, and keeps audit trails understandable even months after the original transaction.
