Why teams connect Bigcommerce and QAD ERP

Keep the storefront in step with the back office: Bigcommerce and QAD ERP share products, inventory, and orders in real time, in both directions.

Bigcommerce runs the storefront and takes the orders; QAD ERP 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 Price Lists, Shipments, Products, Variants and SKUs in Bigcommerce with General ledger transactions, Items, Customers, Suppliers in QAD ERP field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from QAD ERP, order and customer detail from Bigcommerce — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Two-way sync of Products and Variants between BigCommerce and a PIM or ERP so catalog content, SKUs, and pricing stay aligned across systems.
  • 02 Write Inventory levels from a WMS or ERP onto BigCommerce Variants and SKUs so storefront availability reflects warehouse on-hand counts.
  • 03 Push EDI orders from trading partners into QAD as sales orders.
  • 04 Keep supplier and purchase-order records aligned with procurement or AP automation tools.

Common sync patterns

Where QAD ERP is the inventory system of record: stock stays accurate

Available quantities from QAD ERP publish to Bigcommerce, so the store shows what can actually ship and stops overselling.

New orders reach the back office

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

One product catalog

Where both systems keep item records, SKUs, descriptions, and attributes stay aligned so the store and the back office describe the same product.

What you can sync between Bigcommerce and QAD ERP

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.

Bigcommerce objects QAD ERP objects How this pairing syncs
Customers V3 customer accounts, customer groups, and addresses; synced two-way with a CRM so storefront and GTM records match. Customers Account records kept consistent with the sales team's CRM 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 Catalog V3 category tree; mapped for merchandising and kept aligned with a product master or PIM. General ledger transactions Financial postings exported for consolidated reporting Categories is specific to Bigcommerce and General ledger transactions to QAD ERP — each maps to any object or custom field on the other side.
Brands Catalog V3 brand records linked to products; kept aligned with a product master or PIM so brand names and pages stay consistent. Items Item master records shared with CRM, e-commerce, and planning systems Brands is specific to Bigcommerce and Items to QAD ERP — each maps to any object or custom field on the other side.
Inventory Product- or variant-level stock, plus multi-location counts via the V3 Inventory API; written from a WMS to reflect on-hand quantities. Suppliers Vendor master data aligned with procurement and AP automation tools Inventory is specific to Bigcommerce and Suppliers to QAD ERP — each maps to any object or custom field on the other side.
Price Lists V3 price lists and records driving customer-group and B2B pricing; pushed from an ERP so tiered prices stay current. Sales orders Demand records written in from EDI or e-commerce and read out for status Price Lists is specific to Bigcommerce and Sales orders to QAD ERP — each maps to any object or custom field on the other side.
Shipments Order shipments with tracking numbers; created in BigCommerce from a 3PL or fulfillment system as packages ship. Purchase orders Procurement documents mirrored to planning and finance systems Shipments is specific to Bigcommerce and Purchase orders to QAD ERP — each maps to any object or custom field on the other side.

How changes propagate between Bigcommerce and QAD ERP

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.

Bigcommerce QAD ERP Sub-second propagation

DetectionBigcommerce notifies Stacksync of record changes through webhook events. Webhooks push near-real-time events (store/order/*, store/product/*, store/customer/* and more).

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

QAD ERP Bigcommerce Interval-based propagation

DetectionStacksync polls QAD ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the API surface.

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

Rate-limit considerations

  • Bigcommerce: OAuth quota refreshes every 30 seconds and varies by plan (about 20,000 requests/hour on Standard and Plus, 60,000 on Pro, higher on Enterprise); the X-Rate-Limit-Requests-Left header reports remaining calls.
  • QAD ERP: Subject to instance capacity and the platform's API limits.
