Why teams connect Bigcommerce and Sage 300
Keep the storefront in step with the back office: Bigcommerce and Sage 300 share products, inventory, and orders in real time, in both directions.
Bigcommerce runs the storefront and takes the orders; Sage 300 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 Categories, Brands, Inventory, Price Lists in Bigcommerce with Purchase Orders, Inventory Items, AR Invoices and Receipts, AR Customers in Sage 300 field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Sage 300, order and customer detail from Bigcommerce — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- 01 Push Price Lists from an ERP into BigCommerce to drive customer-group and B2B pricing without manual catalog edits.
- 02 Two-way sync of Products and Variants between BigCommerce and a PIM or ERP so catalog content, SKUs, and pricing stay aligned across systems.
- 03 Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
- 04 Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.
Common sync patterns
Where Sage 300 is the inventory system of record: stock stays accurate
Available quantities from Sage 300 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 Sage 300 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 Sage 300
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 300 objects | How this pairing syncs | |
|---|---|---|---|
| Brands Catalog V3 brand records linked to products; kept aligned with a product master or PIM so brand names and pages stay consistent. | AR Customers Receivables customer master synced to CRMs and billing tools. | Brands is specific to Bigcommerce and AR Customers to Sage 300 — 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. | AP Vendors Payables vendor master synced with procurement and payment systems. | Inventory is specific to Bigcommerce and AP Vendors to Sage 300 — 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. | GL Accounts Chart of accounts read for transaction mapping across integrations. | Price Lists is specific to Bigcommerce and GL Accounts to Sage 300 — 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. | Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. | Shipments is specific to Bigcommerce and Journal Batches to Sage 300 — 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. | Order Entry Orders Sales orders written from e-commerce or EDI feeds. | Products is specific to Bigcommerce and Order Entry Orders to Sage 300 — 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. | Purchase Orders Procurement documents read for spend visibility and receiving. | Variants and SKUs is specific to Bigcommerce and Purchase Orders to Sage 300 — each maps to any object or custom field on the other side. |
How changes propagate between Bigcommerce and Sage 300
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 300 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 applied to Sage 300 as a row-level write, with types converted between the two schemas.
Sage 300 Bigcommerce Interval-based propagation
DetectionStacksync polls Sage 300 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.
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.

How the Bigcommerce and Sage 300 connectors work
Bigcommerce
- Integration surface
- REST Management API (V2 and V3), plus GraphQL Storefront and Admin APIs
- Authentication
- OAuth API account credentials — a store-generated client ID and permanent access token sent in the X-Auth-Token header, limited to the OAuth scopes granted when the account is created (e.g. store_v2_orders, store_v2_products)
- Change detection
- Webhooks push near-real-time events (store/order/*, store/product/*, store/customer/* and more); polling uses date_modified:min/max filters on Products, Orders, and Customers

FAQ
Bigcommerce and Sage 300 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bigcommerce and Sage 300: authenticate both systems, choose the objects to sync (such as Bigcommerce's Brands and Inventory), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Bigcommerce: OAuth API tokens are permanent and store-scoped; each is limited to the scopes granted at creation, so a missing scope returns a 403 response. Sage 300: Multi-currency and multi-company operation are core to the data model, and integrations must carry currency and company context on every transaction. Stacksync's field mapping accounts for these differences between Bigcommerce and Sage 300 without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Bigcommerce and Sage 300 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bigcommerce and Sage 300 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bigcommerce–Sage 300 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Bigcommerce and Sage 300. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Bigcommerce: Webhooks push near-real-time events (store/order/*, store/product/*, store/customer/* and more); polling uses date_modified:min/max filters on Products, Orders, and Customers. On Sage 300: Scheduled polling; batch-oriented modules with no webhook surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
