Why teams connect Insightly and Sage 300
Close the gap between front office and back office: Insightly and Sage 300 share customers and status in real time, in both directions.
Insightly holds the customer relationship; Sage 300 runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.
Stacksync syncs Notes, Products, Custom Fields, Contacts in Insightly with AP Vendors, GL Accounts, Journal Batches, Order Entry Orders in Sage 300 field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- Write product usage or billing data from internal databases into Insightly custom fields for account context
- Deduplicate and align customer records between Insightly and an ERP or invoicing system
- Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
- Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.
Where Sage 300 handles order-to-cash: closed-won flows through
A deal won in Insightly creates or updates the customer in Sage 300 with clean data, so fulfillment and invoicing start without re-entry.
Where Sage 300 is the finance system of record: money status on the account
Invoice and payment state from Sage 300 shows on the account in Insightly, so reps see balances before promising the next order.
One customer master
Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
