Why teams connect Shopware and Unleashed Software

Keep the storefront in step with the back office: Shopware and Unleashed Software share products, inventory, and orders in real time, in both directions.

Shopware runs the storefront and takes the orders; Unleashed Software owns the item master, the stock on hand, and the finance behind every transaction. The two overlap wherever the same products, customers, and sales matter to both — and when re-keying or an overnight batch is what connects them, the store oversells items it can't ship, quotes prices finance never set, or leaves buyers waiting on status that already changed.

Stacksync syncs Products, Categories, Customers, Orders in Shopware with Invoices, Products, Stock On Hand, Sales Orders in Unleashed Software field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Unleashed Software, order and customer detail from Shopware — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Write tracking numbers and delivery state onto `order_delivery` from a 3PL or WMS so storefront order status reflects fulfillment.
  • 02 Consolidate orders and customers from multiple `sales_channel` storefronts into one Postgres database for cross-channel analysis.
  • 03 Sync Customers bi-directionally with a CRM so credit terms and delivery addresses match everywhere.
  • 04 Sync Stock On Hand into an ecommerce platform or CRM so quotes and listings reflect real availability.

Common sync patterns

One customer master

Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.

Where Unleashed Software is the inventory system of record: stock stays accurate

Available quantities from Unleashed Software publish to Shopware, so the store shows what can actually ship and stops overselling.

New orders reach the back office

An order captured in Shopware creates the matching record in Unleashed Software with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

What you can sync between Shopware and Unleashed Software

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.

Shopware objects Unleashed Software objects How this pairing syncs
Products The product catalog (`product`), including parent/child variants, per-currency nested price arrays, and stock; synced two-way with ERP, PIM, or a database. Products SKU master records with pricing, units of measure, and inventory settings. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Customers Storefront customer accounts (`customer`) with addresses and group; synced two-way with a CRM or support tool. Customers Buyer records with pricing tiers and delivery addresses. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Categories The navigation and catalogue tree (`category`); mapped to product taxonomy in a warehouse or written from a PIM. Stock Adjustments Manual quantity or value corrections synced for audit and reporting. Categories is specific to Shopware and Stock Adjustments to Unleashed Software — each maps to any object or custom field on the other side.
Orders Order headers (`order`) with totals, state, and sales-channel reference; read out to accounting and written back for status updates. Bills of Materials Production definitions used by assemblies; relevant for manufacturers syncing production data. Orders is specific to Shopware and Bills of Materials to Unleashed Software — each maps to any object or custom field on the other side.
Order Line Items Per-order product rows (`order_line_item`); read alongside the order for revenue and fulfillment reporting. Invoices Sales invoices raised from orders, synced into accounting systems. Order Line Items is specific to Shopware and Invoices to Unleashed Software — each maps to any object or custom field on the other side.
Order Deliveries Shipping records (`order_delivery`) carrying delivery state and tracking codes; written back from a 3PL or WMS. Stock On Hand Quantity and value per product per warehouse; the read source for availability syncs. Order Deliveries is specific to Shopware and Stock On Hand to Unleashed Software — each maps to any object or custom field on the other side.

How changes propagate between Shopware and Unleashed Software

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.

Shopware Unleashed Software Sub-second propagation

DetectionShopware notifies Stacksync of record changes through webhook events. App-system webhooks on entity events (product.written, order.written, customer.written) deliver the changed record's primaryKey and updated field.

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

Unleashed Software Shopware Interval-based propagation

DetectionStacksync polls Unleashed Software for changes on an incremental schedule, reading only records changed since the previous pass. Polling with modified-date filters on list endpoints.

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

Rate-limit considerations

  • Shopware: No general throttle on Admin API entity endpoints; Shopware's RateLimiter guards only specific routes (login, oauth, password reset, guest order/contact) and is configurable on self-hosted stores.
  • Unleashed Software: Subject to the platform's API rate limits; paginate list endpoints and batch where possible.
