Built on PayPal

PayPal moves the money. Dueline does the rest.

Your client pays on PayPal’s own page. Dueline reads the result and never touches a card or bank account.

How a payment reaches Dueline

  1. Dueline

    Creates and sends the invoice through PayPal.

  2. Your client

    Pays on PayPal’s page, by card or PayPal balance.

  3. PayPal

    Sends a signed webhook. Dueline checks the signature.

  4. Your rupees

    Real fee and net amount, from PayPal’s own records.

  • Invoicing v2

    Create, send, remind

    Every invoice is a real PayPal invoice, with your GSTIN, LUT and SAC printed on it.

  • Transactions

    The real fee

    After payment, Dueline reads the actual fee and net from PayPal instead of guessing.

  • Webhooks

    Verified events

    Paid and cancelled events are checked with PayPal before anything changes.

AI that only drafts

  • Gemini reads your chat with emails and phone numbers hidden
  • Every quantity, price, total and date is checked in code
  • Nothing is sent until you click

Two ways to remind a client

PayPal sends its own reminder wording, whatever message we pass. So Nudges gives you two buttons: send PayPal’s reminder, or send the message Dueline drafted from your own email. You can use both, once a day each.

Real PayPal sandbox, end to end.

The demo runs on PayPal’s sandbox, so you can send and pay real invoices without real money.
