Why teams connect Acumatica and Sage 100
Two ERPs, one set of facts: Stacksync keeps Acumatica and Sage 100 consistent in real time, whether they split the business or one is replacing the other.
Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.
Stacksync syncs Invoices, Purchase Orders, Stock Items, Shipments in Acumatica with Journal Entries, Customers, Vendors, Inventory Items in Sage 100 bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.
Common use cases
- 01 Sync vendor bills from AP automation tools into Acumatica for approval and payment.
- 02 Align Acumatica's built-in CRM opportunities and cases with an external sales or support platform.
- 03 Publish item, pricing, and on-hand inventory to online catalogs on a schedule.
- 04 Replicate GL and sales history to a warehouse or Postgres database for reporting off the on-premise system.
Common sync patterns
Split by function
Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
Two-tier roll-up
Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.
Migration in parallel
When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.
What you can sync between Acumatica 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.
| Acumatica objects | Sage 100 objects | How this pairing syncs | |
|---|---|---|---|
| Customers AR master data synced with CRMs and billing tools. | 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. | |
| Vendors Supplier records aligned with procurement and AP automation. | Vendors AP vendor master records synced with procurement and payment tools. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Sales Orders Order documents created from e-commerce and CRM systems, read back for fulfillment status. | Sales Orders Order headers and lines, the usual write target for web and EDI orders. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Purchase Orders Procurement documents exchanged with supplier-facing systems. | Purchase Orders Procurement documents read for spend and receiving workflows. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Payments Customer payment records reconciled against invoices from payment platforms. | GL Accounts Chart of accounts read for mapping transactions in finance integrations. | Payments is specific to Acumatica and GL Accounts to Sage 100 — each maps to any object or custom field on the other side. | |
| Journal Transactions GL entries replicated into reporting databases. | Journal Entries Posted GL activity replicated to warehouses for FP&A. | Journal Transactions is specific to Acumatica and Journal Entries to Sage 100 — each maps to any object or custom field on the other side. |
How changes propagate between Acumatica 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.
Acumatica Sage 100 Sub-second propagation
DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.
DeliveryEach detected change is applied to Sage 100 as a row-level write, with types converted between the two schemas.
Sage 100 Acumatica 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 Acumatica through its API, with automatic retries and rate-limit backoff.

FAQ
Acumatica and Sage 100 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Acumatica and Sage 100: authenticate both systems, choose the objects to sync (such as Acumatica's Customers and Vendors), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for Acumatica and Sage 100: Split by function; Two-tier roll-up; Migration in parallel. Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
-
Acumatica: Contract-based REST API (JSON over versioned endpoints), plus SOAP web services and OData access to Generic Inquiries. Authentication: OAuth 2.0 or cookie-based session login with Acumatica credentials. Sage 100: ODBC (ProvideX driver) for reads; Business Object Interface (BOI) or Sage-provided web services for writes. Authentication: Sage 100 company and user credentials; ODBC DSN credentials for direct reads. Stacksync manages authentication, retries, and rate limits on both sides.
-
Acumatica: Generic Inquiries can be exposed through OData, giving read access to tenant-defined queries without building custom endpoints. Sage 100: Writes should go through the Business Object Interface rather than direct file access, so module validation and GL postings are enforced. Stacksync's field mapping accounts for these differences between Acumatica and Sage 100 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 Acumatica and Sage 100 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Acumatica and Sage 100 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Acumatica–Sage 100 integration in-house.
