Why teams connect Ramp and SAP S/4HANA

Keep Ramp and SAP S/4HANA 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 Departments, Reimbursements, Bills, Vendors in Ramp with Production Orders, Business Partners, Sales Orders, Purchase Orders in SAP S/4HANA 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 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.
  • 02 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.
  • 03 Replicate material master and pricing data to e-commerce and quoting tools.
  • 04 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.

Common sync patterns

Where Ramp handles billing: invoices land in SAP S/4HANA

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.

What you can sync between Ramp and SAP S/4HANA

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.

Ramp objects SAP S/4HANA objects How this pairing syncs
Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. Vendors is specific to Ramp and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side.
Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. Funds (Spend Controls) is specific to Ramp and Billing Documents (Invoices) to SAP S/4HANA — each maps to any object or custom field on the other side.
General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Deliveries Outbound delivery status synced to customer-facing systems for order tracking. General Ledger Accounts is specific to Ramp and Deliveries to SAP S/4HANA — each maps to any object or custom field on the other side.
Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. Journal Entries Financial postings read into warehouses and consolidation tools for reporting. Transactions is specific to Ramp and Journal Entries to SAP S/4HANA — each maps to any object or custom field on the other side.
Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. Cards is specific to Ramp and Customer / Supplier Roles to SAP S/4HANA — each maps to any object or custom field on the other side.
Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Production Orders Manufacturing order status surfaced in planning and operations tools. Users is specific to Ramp and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between Ramp and SAP S/4HANA

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.

Ramp SAP S/4HANA 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 SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

SAP S/4HANA Ramp Interval-based propagation

DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.

DeliveryEach detected change is written to Ramp 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.
  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

Ramp

Integration surface
REST API (Developer API v1)
Authentication
OAuth 2.0: exchange client_id/client_secret (HTTP Basic) at api.ramp.com/developer/v1/token for scoped bearer tokens; client_credentials grant for server-to-server and authorization_code for user-delegated access; scopes follow resource:permission (e.g. transactions:read, bills:write, accounting:write).
Change detection
Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed.
