Why teams connect Apollo.io and Snapfulfil

Close the gap between front office and back office: Apollo.io and Snapfulfil share customers and status in real time, in both directions.

Apollo.io holds the customer relationship; Snapfulfil 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 People (database records), Sequences, Deals (Opportunities), Tasks and calls in Apollo.io with Sales orders, Purchase orders / ASNs, Items (SKUs), Inventory balances in Snapfulfil 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

  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Keep inventory balances aligned between the WMS, the ERP, and selling channels to prevent oversells
  • Sync the item master from the ERP so new SKUs are receivable in the warehouse immediately

Where Snapfulfil is the finance system of record: money status on the account

Invoice and payment state from Snapfulfil shows on the account in Apollo.io, 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.

Where Snapfulfil manages people and org data: keep Apollo.io aligned

Owners, territories, and org structure informed by Snapfulfil stay current in Apollo.io.
