In their own words
Mayday
Mayday is a web-based month-end platform for finance teams using Xero, QuickBooks Online or Intuit Enterprise Suite. It identifies missing or incorrect entries, calculates adjustments for review and approval, then posts approved journals to Xero or QuickBooks. Its products include Flux, Prepayments, Accruals, Deferred Revenue, Balancer, Mayday HQ, BRAG and Recharger. Mayday AIR suggests actions using accounting principles and business context; the maker says it will not train AIR on private customer data without permission. The platform supports approval workflows, audit trails, multi-entity close and recurring templates. The Basic plan is £0/mo, and a 30-day free trial does not require card details. The pricing note lists paid access from £12.50/mo when billed annually, while several listed plans are £10/mo. QuickBooks Online has restrictions: BRAG and Mayday HQ are unavailable, and some functions in Balancer, Recharger, Deferred Revenue and Prepayments are limited. Mayday says its service runs on AWS, with data storage and processing in the London region. It lists encryption, SSO and MFA via Xero and Intuit, role-based access controls and 24/7 infrastructure monitoring.
