Why teams connect Apollo.io and Unleashed Software

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

Apollo.io holds the customer relationship; Unleashed Software 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 Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with Invoices, Products, Stock On Hand, Sales Orders in Unleashed Software 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

  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Sync Customers bi-directionally with a CRM so credit terms and delivery addresses match everywhere.
  • Sync Stock On Hand into an ecommerce platform or CRM so quotes and listings reflect real availability.

Where Unleashed Software handles order-to-cash: closed-won flows through

A deal won in Apollo.io creates or updates the customer in Unleashed Software with clean data, so fulfillment and invoicing start without re-entry.

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

Invoice and payment state from Unleashed Software 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.
