Invoices Tracker

AIPro

Invoicing ledger, client list, and templates for quotes, receipts, POs, and timesheets.

Direct client sharing and clean PDF export (no watermarks, ever).

30 days of Pro on every new account, no credit card required.

Free tier includes 5 saved documents, 5 AI Fills daily, 5 emails to clients, 1 CSV import, and 10 address-book contacts (Pro removes all limits).

SpreadsheetsTraditional billing tools
Most "free" invoicing tools charge you high monthly fees, limit your monthly invoices, or add distracting watermarks. CalculatorAI takes the opposite approach: the tracker is genuinely free, your templates are clean and customizable, and the tedious parts — client matching, calculations, tax items — are handled automatically.
It is part of a wider business workspace (calculators, expense trackers, trading journals and more under one account), so your invoice receipts and tax estimates connect to the tools that help you plan.

Everything a good invoicing system should do — and the parts most skip

Clean PDF generation

Generate professional invoices, quotes, receipts, timesheets, and purchase orders. Brand them with your logo, signature, and choice of colors.

Client address book

Save client details, payment terms, and defaults once. Auto-fill them with a single click on any new document.

Invoice status tracking

Track which invoices are paid, sent, or still in draft. Filter by client, status, and custom date ranges.

AI smart import

Upload existing documents or receipts in any format, and the AI will extract client information, itemized list, taxes, and totals instantly.

Multi-currency & localization

Invoice clients in their native currency. The dashboard automatically converts totals using live exchange rates for unified reporting.

Invoicing dashboard

See your total revenue, pending balances, top clients, and overdue items at a single glance with beautiful analytics.

Private & secure

Your client list and invoicing logs are private. Export all data to CSV (always free) or share direct links with clients.

Payment instructions

Save bank details, PayPal, or Stripe instructions so your clients know exactly how and where to pay you.

AI billing assistant

Extract and structure invoice data in one click

No more manual copy-pasting client info or billing totals. Feed your documents or prompt text directly to the assistant.

Smart actions
