Professional Invoices with Crypto Payment

Shakesco lets you create branded invoices and send them to customers with a crypto payment link included. Customers pay through a secure checkout and you receive a receipt and confirmation automatically.

​
Creating an Invoice from the Dashboard

Go to users.shakesco.com/invoices to create and manage invoices. Shakesco invoice dashboard showing the form on the left and a live invoice preview on the right with SKS invoice number, amount, and line items

​
Invoice form

Fill in the details on the left. The preview on the right updates live:
  • Customer Email: where the invoice is sent (optional for walk-in customers)
  • Description: line item name (e.g. “Platform Services”)
  • Quantity: number of units
  • Unit Price (USD): price per unit
  • Tax Rate (%): applied to the subtotal
  • Total: calculated automatically
The invoice gets a unique number (e.g. SKS-2026-XXXX), a due date, and your business details automatically.
Switch between Invoice and Receipt tabs in the preview to see exactly what your customer will receive at each stage.

​
What Happens Next

  1. Customer receives the invoice by email with a Pay Now link.
  2. They open the secure checkout at pay.shakesco.com and pay with crypto.
  3. You both receive a receipt with the transaction details.

​
Create Invoices via API

For high-volume or automated invoicing, use the Payments API: 
const response = await fetch("https://payments.shakesco.com/invoices", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    type: "public",
    currency: "USD",
    payer_email: "customer@example.com",
    items: [{ description: "Platform Services", unit: 1, price: 1400 }],
  }),
});

const { invoice_number, payment_url } = await response.json();
// Send payment_url to your customer

​
Using the Payment URL

Once you have the payment_url from the API response, you can present it to customers in two ways.

​
Embed as a Button

Add a Pay with Shakesco button to your website or app that links directly to the payment URL. The link opens the Shakesco app via deep link if installed, or falls back to the web checkout in the browser: 
<a href="https://pay.shakesco.com/@yourbusiness/a1b2c3..."
   target="_blank"
   rel="noopener noreferrer">
  Pay with Shakesco
</a>

​
Display as a QR Code

For in-person or printed payments, render the payment_url as a QR code. The customer scans it with any camera app to open the payment page: 
// Using the 'qrcode' npm package
import QRCode from "qrcode";

const canvas = document.getElementById("qr-canvas");
await QRCode.toCanvas(canvas, payment_url);

# Using the 'qrcode' pip package
import qrcode

img = qrcode.make(payment_url)
img.save("invoice_qr.png")
