Why teams connect ConnectWise and Rillet

Connect the financial records in Rillet with the work happening in ConnectWise, 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. ConnectWise 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 Reimbursement, Custom Field, Account, Customer in Rillet and Configurations, Members, Activities, Companies in ConnectWise in sync, bi-directionally and in real time. Whatever records ConnectWise 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 Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
  • 02 Mirror journal entries and contract revenue data into a warehouse for board and ARR reporting.
  • 03 Push closed-won opportunities from the CRM into ConnectWise to kick off agreements and onboarding projects.
  • 04 Reconcile ConnectWise invoices and agreements against the accounting system to catch billing gaps.

Common sync patterns

Where ConnectWise 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 ConnectWise 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 ConnectWise 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.

How changes propagate between ConnectWise 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.

ConnectWise Rillet Sub-second propagation

DetectionConnectWise notifies Stacksync of record changes through webhook events. Callbacks (webhooks) on record changes, supplemented by polling on last-updated fields.

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

Rillet ConnectWise Sub-second propagation

DetectionRillet pushes changes as they happen — webhook events backed by change data capture. Near real-time updates via change tracking.
