Why teams connect Bigcommerce and Sage Intacct

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

Bigcommerce runs the storefront and takes the orders; Sage Intacct 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 Order Entry Transactions, Purchasing Transactions, Dimensions, Employees in Sage Intacct field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Sage Intacct, order and customer detail from Bigcommerce — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Write Inventory levels from a WMS or ERP onto BigCommerce Variants and SKUs so storefront availability reflects warehouse on-hand counts.
  • 02 Sync Customers and customer groups two-way with a CRM so marketing and support see the same accounts and addresses as the storefront.
  • 03 Create AR invoices or Order Entry transactions from subscription and order data held in a Postgres application database.
  • 04 Replicate GL and journal detail, with full dimension tags, to a warehouse for FP&A reporting.

Common sync patterns

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in Sage Intacct, tracking and status flow back to Bigcommerce so buyers see accurate updates.

One customer master

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

Where Sage Intacct is the inventory system of record: stock stays accurate

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

What you can sync between Bigcommerce and Sage Intacct

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 Sage Intacct 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 AR masters synced bi-directionally with CRMs like Salesforce and HubSpot. 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.
Price Lists V3 price lists and records driving customer-group and B2B pricing; pushed from an ERP so tiered prices stay current. Purchasing Transactions Configurable procure-to-pay documents read and written by procurement integrations. Price Lists is specific to Bigcommerce and Purchasing Transactions to Sage Intacct — 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. Dimensions Location, Department, Project, Class and similar tags carried on every synced transaction line. Shipments is specific to Bigcommerce and Dimensions to Sage Intacct — 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. Employees Employee records used for expense and payroll-adjacent syncs. Products is specific to Bigcommerce and Employees to Sage Intacct — 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. GL Accounts Chart of accounts read for mapping synced transactions. Variants and SKUs is specific to Bigcommerce and GL Accounts to Sage Intacct — 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. Journal Entries GL activity written from external systems and replicated to warehouses. Orders is specific to Bigcommerce and Journal Entries to Sage Intacct — each maps to any object or custom field on the other side.

How changes propagate between Bigcommerce and Sage Intacct

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

Sage Intacct Bigcommerce Interval-based propagation

DetectionStacksync polls Sage Intacct for changes on an incremental schedule, reading only records changed since the previous pass. Polling on WHENMODIFIED audit fields.

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.
