Why teams connect Linnworks and Ramp

Keep Ramp and Linnworks 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 Funds (Spend Controls), General Ledger Accounts, Transactions, Cards in Ramp with Channel Listings, Returns & Refunds, Shipping Services, Open Orders in Linnworks 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 Push customer and order data to a CRM or marketing platform for post-purchase campaigns
  • 04 Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports

Common sync patterns

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.

Subsidiary to headquarters

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

What you can sync between Linnworks 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.

Linnworks objects Ramp objects How this pairing syncs
Shipping Services Carrier and service definitions support label and tracking data in order syncs. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Shipping Services is specific to Linnworks and Users to Ramp — each maps to any object or custom field on the other side.
Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Open Orders is specific to Linnworks and Departments to Ramp — each maps to any object or custom field on the other side.
Processed Orders Completed orders feed accounting and warehouse-based margin reporting. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Processed Orders is specific to Linnworks and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Stock Items SKU records keep product data aligned with ERPs and PIMs. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Stock Items is specific to Linnworks and Bills to Ramp — each maps to any object or custom field on the other side.
Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Stock Levels is specific to Linnworks and Vendors to Ramp — each maps to any object or custom field on the other side.
Locations Warehouse and fulfillment location records scope stock data during mapping. Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Locations is specific to Linnworks and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Linnworks 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.

Linnworks Ramp Interval-based propagation

DetectionStacksync polls Linnworks for changes on an incremental schedule, reading only records changed since the previous pass. Polling on order and stock endpoints.

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

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

Rate-limit considerations

  • Linnworks: Per-endpoint rate limits apply on the Linnworks API.
  • 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.
