Why teams connect Bigcommerce and Coupa

Turn every Bigcommerce order into clean revenue: Coupa and Bigcommerce keep customers, orders, and payment status aligned in real time, in both directions.

Bigcommerce runs the storefront — the catalog, the orders, and the buyers placing them. Coupa records the money behind those orders — invoices, revenue, payments, and the ledger the business closes on. The overlap is every customer, order, and product both sides need to agree on, and when that overlap is bridged by CSV export or an overnight batch, finance reconciles against stale numbers while the store quotes prices or stock the books no longer recognize.

Stacksync syncs Expense Reports, Requisitions, Purchase Orders, Invoices in Coupa with Variants and SKUs, Orders, Customers, Categories in Bigcommerce field by field, in real time, and in both directions. You decide which system owns which fields — an order's totals from Bigcommerce, its paid-or-overdue state from Coupa — and Stacksync keeps every copy consistent and resolves conflicts by the rules you set.

The result is one shared record of who bought what and whether it has been paid, so the storefront, support, and the finance team all read from the same current data instead of re-keying it between systems.

Common use cases

  • 01 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 02 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 03 Write Inventory levels from a WMS or ERP onto BigCommerce Variants and SKUs so storefront availability reflects warehouse on-hand counts.
  • 04 Sync Customers and customer groups two-way with a CRM so marketing and support see the same accounts and addresses as the storefront.

Common sync patterns

Refunds and credits reconcile

Refunds, cancellations, and credit notes raised in either system update the corresponding record in the other, keeping balances honest on both sides.

Where Bigcommerce originates orders: sales flow into the books

A new or updated order in Bigcommerce creates or updates the matching invoice or revenue record in Coupa, so billing and reporting start without re-entry.

Where Coupa is the money system of record: payment status on the order

Paid, overdue, and refunded state from Coupa lands on the order or account in Bigcommerce, so the store and support see what has actually been collected.

What you can sync between Bigcommerce and Coupa

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 Coupa objects How this pairing syncs
Price Lists V3 price lists and records driving customer-group and B2B pricing; pushed from an ERP so tiered prices stay current. Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. Price Lists is specific to Bigcommerce and Suppliers to Coupa — 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. Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Shipments is specific to Bigcommerce and Users to Coupa — each maps to any object or custom field on the other side.
Products Catalog V3 records with custom fields and images; mastered in a PIM or ERP and written to BigCommerce, or read out to a warehouse. Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Products is specific to Bigcommerce and Accounts to Coupa — each maps to any object or custom field on the other side.
Variants and SKUs Per-variant pricing and inventory; synced to keep stock and SKU data aligned with an ERP or WMS at the option level. Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Variants and SKUs is specific to Bigcommerce and Contracts to Coupa — each maps to any object or custom field on the other side.
Orders V2 Orders API header, line items, and shipping/billing addresses; read into an ERP or accounting system, with status written back. Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Orders is specific to Bigcommerce and Expense Reports to Coupa — each maps to any object or custom field on the other side.
Customers V3 customer accounts, customer groups, and addresses; synced two-way with a CRM so storefront and GTM records match. Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Customers is specific to Bigcommerce and Requisitions to Coupa — each maps to any object or custom field on the other side.

How changes propagate between Bigcommerce and Coupa

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

Coupa Bigcommerce Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

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.
  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
