Why teams connect Monday and Rillet
Connect the financial records in Rillet with the work happening in Monday, 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. Monday 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 Custom Field, Account, Customer, Vendor in Rillet and Boards, Items, Subitems, Column values in Monday in sync, bi-directionally and in real time. Whatever records Monday 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 of Items and their Column values between a monday.com board and Postgres so ops teams work in SQL while project owners stay in monday.com.
- 04 Write closed deals or provisioning records from a CRM or ERP into monday.com Items to kick off delivery and onboarding boards.
Common sync patterns
Where Monday handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Rillet next to the customer they are helping, without logging into the finance system.
Where Monday 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 Monday 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.
What you can sync between Monday 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.
| Monday objects | Rillet objects | How this pairing syncs | |
|---|---|---|---|
| Users Account members referenced by people columns; read to resolve owner and assignee IDs to names and emails. | Reimbursement Synced with incremental and full sync per the Stacksync docs. | Users is specific to Monday and Reimbursement to Rillet — each maps to any object or custom field on the other side. | |
| Workspaces Top-level containers that hold boards; used to scope which boards a given sync covers. | Custom Field Synced with incremental and full sync per the Stacksync docs. | Workspaces is specific to Monday and Custom Field to Rillet — each maps to any object or custom field on the other side. | |
| Boards Table-like containers that hold items; each board maps to a synced table, and its columns define the field mapping. | Account Synced with incremental and full sync per the Stacksync docs. | Boards is specific to Monday and Account to Rillet — each maps to any object or custom field on the other side. | |
| Items Rows within a board and the primary record; synced two-way and created, updated, archived, or deleted via GraphQL mutations. | Customer Synced with incremental and full sync per the Stacksync docs. | Items is specific to Monday and Customer to Rillet — each maps to any object or custom field on the other side. | |
| Subitems Nested rows under items, stored on a separate hidden board; synced as a child table linked to the parent item. | Vendor Synced with incremental and full sync per the Stacksync docs. | Subitems is specific to Monday and Vendor to Rillet — each maps to any object or custom field on the other side. | |
| Column values Typed fields (status, date, people, numbers, connect-boards); polymorphic JSON usually written together via change_multiple_column_values. | Invoice Synced with incremental and full sync per the Stacksync docs. | Column values is specific to Monday and Invoice to Rillet — each maps to any object or custom field on the other side. |
How changes propagate between Monday 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.
Monday Rillet Sub-second propagation
DetectionMonday notifies Stacksync of record changes through webhook events. Board-scoped webhooks (create_item, change_column_value, item_deleted, and similar) for real-time events.
DeliveryEach detected change is written to Rillet through its API, with automatic retries and rate-limit backoff.
Rillet Monday 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 Monday through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Monday: Complexity-budget limits: a single query caps at 5M complexity points and ~10M points/min per user token (1M on trial/free) over a sliding 60s window.
- Rillet: Subject to the platform's API rate limits.

FAQ
Monday and Rillet integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Monday and Rillet: authenticate both systems, choose the objects to sync (such as Monday's Users and Workspaces), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for Monday and Rillet: Where Monday handles customer conversations: billing context in view; Where Monday collects payments or triggers charges: events land in Rillet; Where Monday tracks people or companies: one identity.

Monday: GraphQL API (single endpoint, api.monday.com/v2). Authentication: OAuth 2.0 for installed apps, or a per-user personal API token (admin/member scope); a date-based API version is sent via request header. Rillet: REST API (OpenAPI-specified, with production and sandbox environments). Authentication: API key generated in Rillet (Organization Setting -> API Access); uncheck Read Only for bidirectional sync, check Read Only for one-way sync. Stacksync manages authentication, retries, and rate limits on both sides.
-
Rillet: The REST API authenticates with API keys and publishes an OpenAPI specification, with separate production and sandbox environments. Monday: Column values are polymorphic JSON that differ by column type; writes must send correctly shaped values, typically batched via change_multiple_column_values. Stacksync's field mapping accounts for these differences between Monday and Rillet 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 Monday and Rillet records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Monday and Rillet connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Monday–Rillet integration in-house.
