Why teams connect Copper CRM and QuickBooks

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

Finance and sales describe the same customers in different systems. Copper CRM 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 Accounts, Journal entries, Estimates, Purchase orders in QuickBooks to Activities, Tasks, Projects, Pipelines in Copper CRM 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

  • Sync invoices and payments between QuickBooks and the CRM so sales sees billing status on the account record.
  • Mirror the chart of accounts and journal entries into a warehouse for consolidated financial reporting.
  • Keep Copper contact data aligned with a marketing automation tool so Gmail-sourced contacts enter nurture flows.
  • Enrich Copper records with product usage or firmographic data from an internal database to guide follow-up.

Where Copper CRM 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.

Payment status on the account

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

Billing detail changes flow back

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