Invoicing
Two tools: payment requests you send to customers (with expiry and email delivery), and downloadable PDF tax invoices for completed payments.
Payment requests#
A payment request is a collect link you send to a customer. It creates a checkout titled "Payment Request" behind the scenes and tracks whether the customer has opened it.
- In the console, open Create Payment Request and set amount, currency, title, and an optional note
- Choose an expiry: 15 minutes, 1 hour, 24 hours, 7 days, or 30 days (your last choice is remembered)
- Send it: copy the link, or let U.CASH email the customer directly with a Pay Now button and a copy-paste fallback link
The customer sees a normal hosted checkout - every coin, card, and bank method you have enabled - and the request shows Unopened → Opened → Paid in your transaction list until it completes or expires.
Payment link shapes#
Every checkout resolves to a clean, shareable URL:
| Shape | When |
|---|---|
https://pay.u.cash/checkout/<slug> | Saved checkout with a custom slug |
https://pay.u.cash/id/<encrypted-id> | One-off checkout or payment request |
https://pay.u.cash/invoice/<encrypted-id> | Customer-facing invoice page |
The path prefixes are configurable - see URL Rewrite.
PDF tax invoices#
Once a payment is confirmed and billing details exist, U.CASH generates a branded Tax Invoice PDF (numbered, with your business profile, purchase details, and a VAT line when tax applies). Customers can download it from their invoice page; you can regenerate and download it from the transaction panel.
- Enable under Settings → Taxes & Invoicing, and set an invoice number prefix (default
INV-) - Billing details (name, address, city, state, ZIP, country, VAT number) are collected from the customer on the invoice page; the PDF regenerates when they update them
- Optional invoice details text overrides the business-profile block if you need custom legal wording
Open amounts#
Leave the amount blank on a payment request (or any checkout) to let the customer choose what to pay - useful for deposits, tips, and pay-what-you-want sales. Open-amount transactions are exempt from underpayment checks and tax lines.
