InvoiceAgent vs BigTime
BigTime is built for firms that want project accounting, utilization reporting, and professional-services operations wrapped together. InvoiceAgent is a better fit when you want a lighter billing layer that still handles recurring sends, tracked-hour imports, reminders, and more polished invoice delivery.
Choose BigTime
BigTime is a fit when your firm needs project accounting, staffing visibility, and broader PSA-style workflow management.
Choose InvoiceAgent
Teams that want tracked work to feed into a calmer invoicing workflow with branded PDFs, reminders, recurring schedules, and less software overhead.
Timing-first invoicing
Schedule the invoice once. Weekend rules, reminders, recurring sends, manual-send overrides, and PDF delivery stay coordinated from one queue.
Live FX at dispatch
Draft early in the source currency. Let the final conversion happen when the invoice actually goes out.
Branding and time-tracking built in
Choose invoice templates, colors, fonts, logo treatment, and import billable hours from WakaTime or Toggl without adding another tool.

Consultants, agencies, and service firms deciding between a professional-services suite and a more focused invoice dispatch workflow.
