Why teams connect Manhattan Associates WMS and Ramp

Keep Ramp and Manhattan Associates WMS agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Reimbursements, Bills, Vendors, Funds (Spend Controls) in Ramp with Inventory, Items, Shipments & LPNs, Receipts in Manhattan Associates WMS in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
  • 02 Two-way sync Transactions and their accounting codings with a Postgres warehouse so finance analyzes spend in SQL and pushes GL categories and memos back to Ramp.
  • 03 Feed labor and throughput data into analytics tools for DC performance reporting.
  • 04 Release orders from the ERP or OMS into the WMS and sync status back as they are waved, picked, and shipped.

Common sync patterns

Where Ramp handles billing: invoices land in Manhattan Associates WMS

Invoices and payment activity from the billing side post through to the enterprise system automatically.

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.
