Why teams connect Linnworks and QuickBooks
Keep QuickBooks 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 Estimates, Purchase orders, Credit memos, Customers in QuickBooks with Suppliers, Channel Listings, Returns & Refunds, Shipping Services 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 Create QuickBooks invoices automatically from closed-won deals or e-commerce orders.
- 02 Keep customer records consistent between QuickBooks and support or subscription-management tools.
- 03 Sync product and listing data with a PIM so channel listings stay aligned with the catalog
- 04 Push customer and order data to a CRM or marketing platform for post-purchase campaigns
Common sync patterns
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 QuickBooks serves a business unit and Linnworks is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.
Where QuickBooks handles billing: invoices land in Linnworks
Invoices and payment activity from the billing side post through to the enterprise system automatically.

How changes propagate between Linnworks and QuickBooks
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 QuickBooks 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 QuickBooks through its API, with automatic retries and rate-limit backoff.
QuickBooks Linnworks Sub-second propagation
DetectionQuickBooks pushes changes as they happen — webhook events backed by change data capture. Webhooks for entity change events, plus a Change Data Capture query operation for pull-based deltas.
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.
- QuickBooks: Subject to per-realm API request limits.

-
Common patterns for Linnworks and QuickBooks: One customer and vendor master; Subsidiary to headquarters; Where QuickBooks handles billing: invoices land in Linnworks. Where both systems keep records of the same organizations, corrections made in either propagate to the other.
-
Linnworks: REST API. Authentication: Application credentials and an install token exchanged for a session token. QuickBooks: REST API (QuickBooks Online). Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
-
QuickBooks: Updates must include the record's current SyncToken; stale tokens are rejected, giving built-in optimistic concurrency control. Linnworks: The Linnworks API uses a token-exchange model: application credentials plus a per-account install token are exchanged for a session token that authorizes subsequent calls. Stacksync's field mapping accounts for these differences between Linnworks and QuickBooks without custom code.
