Wave
· #124 most-usedFree invoicing and accounting — now agent-powered
Wave is free invoicing, accounting, and receipts software built for small businesses and freelancers. Connect it to Actionist and your agents can create customers, generate and send invoices, record payments, and monitor outstanding balances — all triggered by events in your other tools, with no manual data entry between systems.
Eliminates manual work. Agents eliminate the manual steps of creating customer records, generating invoices, reconciling payments, and copying transaction data between Wave and other tools like CRMs or spreadsheets.
What your Wave agent runs on autopilot
A week of scheduled jobs your Actionist agent will execute on your behalf.
Wave × every other app you use
End-to-end automations that span multiple apps — each one a real business outcome.
Turn a payment email into a closed invoice in 60 seconds
When a client emails to say they've paid, your agent doesn't wait for you to log in to Wave. It reads the email, finds the matching open invoice, records the payment, posts a confirmation to your team Slack, and schedules a follow-up calendar event for the account check-in — all before you've finished reading the message.
