Why teams connect Apollo.io and DEAR Inventory
Close the gap between front office and back office: Apollo.io and DEAR Inventory share customers and status in real time, in both directions.
Apollo.io holds the customer relationship; DEAR Inventory 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 Contacts, Accounts, People (database records), Sequences in Apollo.io with Products, Stock levels, Sale orders, Purchase orders in DEAR Inventory 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.
- Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
- Land orders, costs, and inventory movements in a warehouse for margin and stock-turn reporting.
Where DEAR Inventory is the finance system of record: money status on the account
Invoice and payment state from DEAR Inventory 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 DEAR Inventory manages people and org data: keep Apollo.io aligned
Owners, territories, and org structure informed by DEAR Inventory stay current in Apollo.io.
