Mayday

Mayday is a London-headquartered accounting technology company that builds software to automate month-end finance processes. Founded in 2020, it serves in-house finance teams, CFOs, financial controllers, and accounting and bookkeeping firms working with growing businesses and multi-entity groups. Its products address spreadsheet-intensive tasks that otherwise require manual calculations, reconciliations and journal entries.

The platform operates as an automation layer over cloud accounting systems, chiefly Xero, QuickBooks Online and Intuit Enterprise Suite. Its approach allows businesses to extend their existing accounting systems as their financial operations become more complex, rather than migrating to an enterprise resource planning platform. Mayday combines coordination of the financial close with automation of the underlying accounting work.

Intercompany and accounting automation

Mayday’s intercompany suite covers several connected workflows. Balancer synchronizes intercompany loans and accounts receivable and payable balances across general ledgers. Recharger calculates and posts intercompany and interdepartmental revenue and expense allocations. BRAG, short for Bank Reconciliation Across Group, supports cross-entity bank reconciliation within Xero, while HQ centralizes changes to charts of accounts and tracking categories across entities.

Its core accounting modules automate deferred revenue recognition, prepaid expense schedules and accrual journals. Flux adds AI-assisted analysis of month-on-month profit-and-loss movements, identifying anomalies and helping finance teams explain variances. These modules address recurring accounting work alongside the reconciliation and coordination tasks needed to complete a close.

Financial close management

In February 2026, Mayday acquired Easy Month End, a New Zealand-developed close management platform. The acquisition brought task checklists, balance sheet reconciliation workflows, sign-offs and progress tracking together with Mayday’s accounting automation products, connecting preparation and review with journal posting.

Beyond its software, Mayday operates CFO Techstack, a content and community platform for finance leaders scaling businesses on cloud accounting systems. Its Practice HQ and partner programme provide multi-client workflows and packages for accounting and bookkeeping firms, extending the platform’s use beyond individual in-house finance teams.
