Why teams connect Microsoft 365 and Rillet

Connect the financial records in Rillet with the work happening in Microsoft 365, 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. Microsoft 365 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 OneDrive Files (driveItems), SharePoint Sites & Lists, Teams, Planner & To Do Tasks in Microsoft 365 in sync, bi-directionally and in real time. Whatever records Microsoft 365 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

  • Sync AR and collection status back to customer success tools ahead of renewals.
  • Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
  • Sync employee records from an HR system into Entra ID users and group memberships.
  • Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.

Where Microsoft 365 is a docs or knowledge workspace: reference data kept fresh

Figures teams rely on, like customer status or outstanding balances, stay current wherever Microsoft 365 surfaces them instead of going stale after a one-time paste.

Where Microsoft 365 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 Microsoft 365 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.
