Two-way sync
Changes in Insightly or QuickBooks instantly reflect in both systems. No stale data, no manual imports.
Keep Insightly and QuickBooks in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Finance and sales describe the same customers in different systems. Insightly 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 Invoices, Payments, Bills, Vendors in QuickBooks to Notes, Products, Custom Fields, Contacts in Insightly 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.
When a contact or address is corrected in Insightly, QuickBooks gets the update before the next invoice goes out.
Finance sees the account owner and relationship history from Insightly when chasing a balance, and sales sees that the chase is happening.
A won opportunity creates or updates the customer in QuickBooks with the right billing details, so invoicing starts without re-keying.
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Insightly objects | QuickBooks objects | |
|---|---|---|
| Custom Fields Per-object custom fields carry enrichment and billing data written from external systems. | Bills Payables written in from procurement systems for AP processing | |
| Contacts Person records sync with marketing and support tools to keep one contact list. | Vendors Supplier records aligned with purchasing and spend tools | |
| Organizations Company records map to accounts in ERPs and other CRMs. | Items Products and services referenced on invoice and bill lines | |
| Leads Unqualified prospects sync in from forms and enrichment sources before conversion. | Accounts The chart of accounts, mirrored so external postings map to the right ledger lines | |
| Opportunities Pipeline records feed forecasting and warehouse-based reporting. | Journal entries Manual postings exported for consolidated financial reporting | |
| Projects Delivery records created from won opportunities sync with PSA and task tools. | Estimates Quotes that convert to invoices, synced with CRM quoting flows |
