Why teams connect Sage 300 and Smartsheet
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Smartsheet and Sage 300.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Smartsheet is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.
Stacksync syncs Columns, Cells, Reports, Attachments in Smartsheet with Inventory Items, AR Invoices and Receipts, AR Customers, AP Vendors in Sage 300 bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.
Common use cases
- 01 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
- 02 Write records from a CRM or ERP into Smartsheet Rows so ops teams manage intake and status in a grid, then push status Cells back to the source.
- 03 Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.
- 04 Write web and EDI orders into Order Entry and return order status to the source channel.
Common sync patterns
Master data corrections travel
A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
Where Smartsheet faces customers and Sage 300 carries account records
Order, invoice, or account status from Sage 300 appears alongside the customer in Smartsheet, so front-line teams answer from live data.
Where Sage 300 is the HR or people system of record
Worker and organization data from Sage 300 stays current in Smartsheet, so the tools people use daily reflect the org as it actually is.
What you can sync between Sage 300 and Smartsheet
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.
| Sage 300 objects | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| AP Vendors Payables vendor master synced with procurement and payment systems. | Sheets The core container; each sheet has typed columns, rows, and a modifiedAt stamp. Stacksync treats a sheet as a table and syncs its rows two-way. | AP Vendors is specific to Sage 300 and Sheets to Smartsheet — each maps to any object or custom field on the other side. | |
| GL Accounts Chart of accounts read for transaction mapping across integrations. | Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | GL Accounts is specific to Sage 300 and Rows to Smartsheet — each maps to any object or custom field on the other side. | |
| Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Journal Batches is specific to Sage 300 and Columns to Smartsheet — each maps to any object or custom field on the other side. | |
| Order Entry Orders Sales orders written from e-commerce or EDI feeds. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Order Entry Orders is specific to Sage 300 and Cells to Smartsheet — each maps to any object or custom field on the other side. | |
| Purchase Orders Procurement documents read for spend visibility and receiving. | Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. | Purchase Orders is specific to Sage 300 and Reports to Smartsheet — each maps to any object or custom field on the other side. | |
| Inventory Items Item master with costing and quantities, synced to storefronts and WMS. | Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. | Inventory Items is specific to Sage 300 and Attachments to Smartsheet — each maps to any object or custom field on the other side. |
How changes propagate between Sage 300 and Smartsheet
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.
Sage 300 Smartsheet 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 Smartsheet through its API, with automatic retries and rate-limit backoff.
Smartsheet Sage 300 Sub-second propagation
DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.
DeliveryEach detected change is applied to Sage 300 as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.

FAQ
Sage 300 and Smartsheet integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Sage 300 and Smartsheet: authenticate both systems, choose the objects to sync (such as Sage 300's AP Vendors and GL Accounts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Smartsheet: A sheet is capped at 500,000 cells (rows multiplied by columns), and no single cell can hold more than 4,000 characters. 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 Sage 300 and Smartsheet 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 Sage 300 and Smartsheet records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Sage 300 and Smartsheet connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Sage 300–Smartsheet integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Sage 300 and Smartsheet. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Sage 300: Scheduled polling; batch-oriented modules with no webhook surface. On Smartsheet: Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes; otherwise polling on sheet and row modifiedAt timestamps. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
