Why teams connect Rillet and Smartsheet
Connect the financial records in Rillet with the work happening in Smartsheet, so both stay current without exports or copy-paste.
Rillet holds the financial truth: who the customers are, what they were billed, what they paid. Smartsheet is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Bill, Journal Entry, Invoice Payment, Charge in Rillet and Cells, Reports, Attachments, Discussions and Comments in Smartsheet in sync, bi-directionally and in real time. Whatever records Smartsheet keeps and whatever events it produces, the overlap with Rillet is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- 01 Sync AR and collection status back to customer success tools ahead of renewals.
- 02 Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
- 03 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
- 04 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.
Common sync patterns
Where Smartsheet collects payments or triggers charges: events land in Rillet
Payment and charge activity flows into Rillet as it happens, so the books reflect reality without manual reconciliation.
Where Smartsheet tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
Where Smartsheet is a docs or knowledge workspace: reference data kept fresh
Figures teams rely on, like customer status or outstanding balances, stay current wherever Smartsheet surfaces them instead of going stale after a one-time paste.
What you can sync between Rillet 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.
| Rillet objects | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| Invoice Synced with incremental and full sync per the Stacksync docs. | Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. | Invoice is specific to Rillet and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side. | |
| Credit Memo Synced with incremental and full sync per the Stacksync docs. | Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. | Credit Memo is specific to Rillet and Users and Groups to Smartsheet — each maps to any object or custom field on the other side. | |
| Bill Synced with incremental and full sync per the Stacksync docs. | 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. | Bill is specific to Rillet and Sheets to Smartsheet — each maps to any object or custom field on the other side. | |
| Journal Entry Synced with incremental and full sync per the Stacksync docs. | Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | Journal Entry is specific to Rillet and Rows to Smartsheet — each maps to any object or custom field on the other side. | |
| Invoice Payment Synced with incremental and full sync per the Stacksync docs. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Invoice Payment is specific to Rillet and Columns to Smartsheet — each maps to any object or custom field on the other side. | |
| Charge Synced with incremental and full sync per the Stacksync docs. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Charge is specific to Rillet and Cells to Smartsheet — each maps to any object or custom field on the other side. |
How changes propagate between Rillet 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.
Rillet Smartsheet Sub-second propagation
DetectionRillet pushes changes as they happen — webhook events backed by change data capture. Near real-time updates via change tracking.
DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.
Smartsheet Rillet 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 written to Rillet through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Rillet: Subject to the platform's API rate limits.
- 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
Rillet and Smartsheet integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Rillet and Smartsheet: authenticate both systems, choose the objects to sync (such as Rillet's Invoice and Credit Memo), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 Rillet and Smartsheet records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Rillet and Smartsheet connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Rillet–Smartsheet integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Rillet and Smartsheet. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Rillet: Near real-time updates via change tracking; incremental sync per object, with delete detection (some objects checked every 1h or 4h). 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.
-
On the Rillet side: Bill, Journal Entry, Invoice Payment, Charge, plus custom fields where Rillet exposes them. On the Smartsheet side: Cells, Reports, Attachments, Discussions and Comments. Stacksync auto-detects both schemas and converts types between the two systems.
