Why teams connect Affinity and QuickBooks

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

Finance and sales describe the same customers in different systems. Affinity knows the relationship: who the contacts are and what is in motion with the account. QuickBooks 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 Estimates, Purchase orders, Credit memos, Customers in QuickBooks to List Entries, Persons, Organizations, Opportunities in Affinity 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

  • Mirror the chart of accounts and journal entries into a warehouse for consolidated financial reporting.
  • Create QuickBooks invoices automatically from closed-won deals or e-commerce orders.
  • Push enrichment data computed elsewhere into Affinity field values on list entries.
  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.

Billing detail changes flow back

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

Collections with context

Finance sees the account owner and relationship history from Affinity when chasing a balance, and sales sees that the chase is happening.

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

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