Why teams connect Nutshell and QuickBooks

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

Finance and sales describe the same customers in different systems. Nutshell 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 Journal entries, Estimates, Purchase orders, Credit memos in QuickBooks to Tags, Users, Leads, People in Nutshell 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.
  • Write subscription or product data from internal systems into Nutshell so reps see account context.
  • Mirror tasks and activities into ops tools for cross-team visibility.

Collections with context

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

Where Nutshell 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 Nutshell, so reps see overdue balances before they promise the next order.
