Why teams connect Notion and Rillet

Connect the financial records in Rillet with the work happening in Notion, 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. Notion 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 Invoice Payment, Charge, Reimbursement, Custom Field in Rillet and Properties, Blocks, Formula and Rollup properties, Users in Notion in sync, bi-directionally and in real time. Whatever records Notion 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 Push billing events from a product or usage-metering system into Rillet for revenue recognition.
  • 02 Sync AR and collection status back to customer success tools ahead of renewals.
  • 03 Push rows from a warehouse or another database into a Notion data source as Pages so ops and leadership read live metrics in a familiar Notion view.
  • 04 Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.

Common sync patterns

Where Notion 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 Notion 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 Notion is a docs or knowledge workspace: reference data kept fresh

Figures teams rely on, like customer status or outstanding balances, stay current wherever Notion surfaces them instead of going stale after a one-time paste.

What you can sync between Notion and Rillet

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.

Notion objects Rillet objects How this pairing syncs
Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Invoice Payment Synced with incremental and full sync per the Stacksync docs. Properties is specific to Notion and Invoice Payment to Rillet — each maps to any object or custom field on the other side.
Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Charge Synced with incremental and full sync per the Stacksync docs. Blocks is specific to Notion and Charge to Rillet — each maps to any object or custom field on the other side.
Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Reimbursement Synced with incremental and full sync per the Stacksync docs. Formula and Rollup properties is specific to Notion and Reimbursement to Rillet — each maps to any object or custom field on the other side.
Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Custom Field Synced with incremental and full sync per the Stacksync docs. Users is specific to Notion and Custom Field to Rillet — each maps to any object or custom field on the other side.
Comments Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system. Account Synced with incremental and full sync per the Stacksync docs. Comments is specific to Notion and Account to Rillet — each maps to any object or custom field on the other side.
Files and attachments File-property and file-block values. Notion-hosted URLs are temporary and expire, so files are re-fetched or copied at sync time. Customer Synced with incremental and full sync per the Stacksync docs. Files and attachments is specific to Notion and Customer to Rillet — each maps to any object or custom field on the other side.

How changes propagate between Notion and Rillet

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.

Notion Rillet Sub-second propagation

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

DeliveryEach detected change is written to Rillet through its API, with automatic retries and rate-limit backoff.

Rillet Notion 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 Notion through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations
