Why teams connect Coupa and HubSpot

Sync customers, invoices, and payment status between Coupa and HubSpot in real time, so sales sees the money and finance sees the relationship.

Finance and sales describe the same customers in different systems. HubSpot knows the relationship: who the contacts are and what is in motion with the account. Coupa knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.

Stacksync links Expense Reports, Requisitions, Purchase Orders, Invoices in Coupa to Company, Deal, Line Item, Product in HubSpot with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.

Common use cases

  • 01 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 02 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 03 Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • 04 Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.

Common sync patterns

Where HubSpot tracks deals: closed-won creates the finance record

A won opportunity creates or updates the customer in Coupa with the right billing details, so invoicing starts without re-keying.

Payment status on the account

Invoice and payment status from Coupa appears on the account in HubSpot, so reps see overdue balances before they promise the next order.

Billing detail changes flow back

When a contact or address is corrected in HubSpot, Coupa gets the update before the next invoice goes out.
