Why Connect Expensify to KeyPay?

New team members take longer to onboard because they must learn manual workarounds to keep Expensify and KeyPay aligned

KeyPay adds complexity: reporting is adequate for standard payroll needs but requires exports for custom workforce analytics or cross-referencing with other systems

Manually copying data between Expensify and KeyPay wastes hours every week that could be spent on revenue-generating work

Reporting across Expensify and KeyPay requires painful manual exports and spreadsheet merges

Transaction data in Expensify requires manual verification against KeyPay, increasing audit risk

No single source of truth when expenses live in two disconnected tools, so staff second-guess which system has the correct information

Client engagement details in Expensify and time-tracking data in KeyPay do not align, making billing inaccurate
