Why teams connect Acumatica and Ramp

Keep Ramp and Acumatica 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 Bills, Vendors, Funds (Spend Controls), General Ledger Accounts in Ramp with Opportunities and Cases, Customers, Vendors, Sales Orders in Acumatica 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 Mirror Bills and their approval and payment state into an AP or ERP system, marking each one ready-to-sync then synced to keep both ledgers reconciled.
  • 02 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
  • 03 Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
  • 04 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.

Common sync patterns

Subsidiary to headquarters

Where Ramp serves a business unit and Acumatica is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where Ramp handles billing: invoices land in Acumatica

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.

What you can sync between Acumatica and Ramp

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

How changes propagate between Acumatica and Ramp

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Acumatica Ramp Sub-second propagation

DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.

DeliveryEach detected change is written to Ramp through its API, with automatic retries and rate-limit backoff.

Ramp Acumatica Sub-second propagation

DetectionRamp notifies Stacksync of record changes through webhook events. Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events.

DeliveryEach detected change is written to Acumatica through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Ramp: 200 requests per 10-second rolling window per source IP; exceeding it returns 429 Too Many Requests, and requests running over 60 seconds return 504. Results use keyset pagination (follow the page.next URL / start cursor); higher limits can be requested from support.
