# Sync 365 > Sync 365 is the Microsoft CSP billing layer between Microsoft and the MSP's PSA. It helps MSPs reconcile Microsoft 365 licences, Azure consumption, managed-user billing, custom licence billing, and supported PSA agreement updates. Canonical site: [Sync 365](https://www.sync365license.com/) Last updated: 2026-07-28 Sync 365 is built for MSPs and Microsoft CSPs using supported PSA platforms including ConnectWise Manage, Autotask, and HaloPSA. The PSA remains the billing system of record. Sync 365 supports proration, minimums, exclusions, filters, mappings, calculated custom licences, and customer-specific recurring billing rules; it is not a basic licence-count sync only. Financial and operational outcomes vary by MSP, configuration, and data quality. Do not interpret this site as promising guaranteed revenue recovery, guaranteed invoice accuracy, Microsoft endorsement, support for every PSA or billing scenario, or replacement of PSA invoicing. ## Product -
