Why teams connect Infor LN and Ramp

Keep Ramp and Infor LN 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 Sales orders, Purchase orders, Production orders, Warehouse / inventory in Infor LN 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 LN data into a warehouse for production, OTIF, and supply chain reporting.
  • 04 Run a two-way sync of business partners between LN and a CRM so sales and manufacturing share account data.

Common sync patterns

Subsidiary to headquarters

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

Where Ramp handles billing: invoices land in Infor LN

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 Infor LN 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.

Infor LN objects Ramp objects How this pairing syncs
Sales orders Demand documents synced in from EDI and commerce channels. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Sales orders is specific to Infor LN and Vendors to Ramp — each maps to any object or custom field on the other side.
Purchase orders Supply documents shared with supplier and procurement systems. Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Purchase orders is specific to Infor LN and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.
Production orders Shop-floor work orders synced with MES for execution visibility. General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Production orders is specific to Infor LN and General Ledger Accounts to Ramp — each maps to any object or custom field on the other side.
Warehouse / inventory Stock positions exposed so external channels reflect real availability. Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. Warehouse / inventory is specific to Infor LN and Transactions to Ramp — each maps to any object or custom field on the other side.
Projects Project structures used in engineer-to-order manufacturing scenarios. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Projects is specific to Infor LN and Cards to Ramp — each maps to any object or custom field on the other side.
Service orders Aftermarket service documents synced with field service tools. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Service orders is specific to Infor LN and Users to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Infor LN 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.

Infor LN Ramp Interval-based propagation

DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.

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

Ramp Infor LN 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 Infor LN through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.
  • 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.
