Why teams connect Bigcommerce and Sage 100
Keep the storefront in step with the back office: Bigcommerce and Sage 100 share products, inventory, and orders in real time, in both directions.
Bigcommerce runs the storefront and takes the orders; Sage 100 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, GL Accounts, Journal Entries, Customers in Sage 100 field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Sage 100, order and customer detail from Bigcommerce — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- 01 Sync Customers and customer groups two-way with a CRM so marketing and support see the same accounts and addresses as the storefront.
- 02 Push Price Lists from an ERP into BigCommerce to drive customer-group and B2B pricing without manual catalog edits.
- 03 Replicate GL and sales history to a warehouse or Postgres database for reporting off the on-premise system.
- 04 Sync customers, invoices, and payment status into a CRM so sales sees AR standing without opening the ERP.
Common sync patterns
One customer master
Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.
Where Sage 100 is the inventory system of record: stock stays accurate
Available quantities from Sage 100 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 100 with customer, line items, and totals, so fulfillment and invoicing start without re-entry.
What you can sync between Bigcommerce and Sage 100
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 100 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 customer master records synced to CRMs for account and credit visibility. | 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. | |
| Inventory Product- or variant-level stock, plus multi-location counts via the V3 Inventory API; written from a WMS to reflect on-hand quantities. | Purchase Orders Procurement documents read for spend and receiving workflows. | Inventory is specific to Bigcommerce and Purchase Orders to Sage 100 — 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 mapping transactions in finance integrations. | Price Lists is specific to Bigcommerce and GL Accounts to Sage 100 — 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 Entries Posted GL activity replicated to warehouses for FP&A. | Shipments is specific to Bigcommerce and Journal Entries to Sage 100 — 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. | Vendors AP vendor master records synced with procurement and payment tools. | Products is specific to Bigcommerce and Vendors to Sage 100 — 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. | Inventory Items Item master with pricing and quantities, synced to e-commerce catalogs. | Variants and SKUs is specific to Bigcommerce and Inventory Items to Sage 100 — each maps to any object or custom field on the other side. |
How changes propagate between Bigcommerce and Sage 100
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 100 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 100 as a row-level write, with types converted between the two schemas.
Sage 100 Bigcommerce Interval-based propagation
DetectionStacksync polls Sage 100 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.

FAQ
Bigcommerce and Sage 100 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bigcommerce and Sage 100: authenticate both systems, choose the objects to sync (such as Bigcommerce's Customers and Inventory), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 100: Scheduled polling; no webhooks or change log on the integration surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Bigcommerce side: Categories, Brands, Inventory, Price Lists, plus custom fields where Bigcommerce exposes them. On the Sage 100 side: Purchase Orders, GL Accounts, Journal Entries, Customers. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Bigcommerce and Sage 100: One customer master; Where Sage 100 is the inventory system of record: stock stays accurate; New orders reach the back office. Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.
