TentaBill turns tracked time into polished, paid invoices — and Percy, your built-in AI first mate, logs time, drafts and sends invoices, and charts your numbers, just by asking.
Ask Percy about your time, invoices, or customers; it logs time, drafts and sends invoices, and charts your revenue — inline, in a tap. It only ever touches what you allow (read, log time, generate PDFs, send email — each behind a switch), on your own AI key or a metered managed tier with a monthly cap.
Chart your hours against projects — they auto-compute from start and end. Import from Clockify if you like.
Log a billing period into a polished PDF invoice, and keep every version in the ledger.
Send invoices off from your own Microsoft 365 mailbox — no forwarding, no copy-paste.
Record a payment and the status flips to Paid automatically; remove it and it flips right back.
Outstanding balances bucketed by days past due — a lighthouse for anything drifting overdue.
Sync time-off from Outlook and import public holidays; capacity drops automatically.
Your workspace is set up instantly and invoice email is ready immediately — no separate signup.
