Invoice Generation with Paychainly: PDF Invoices for Crypto Payments

May 21, 2026· 1 min read

Why Invoices Matter for Crypto

Crypto payments are permanent but leave no paper trail that accounting teams understand. PDF invoices bridge the gap between blockchain records and business accounting systems.

Enabling Invoice Generation

Configure your invoice template in Dashboard → Settings → Invoices:

  • Company name, address, VAT number
  • Logo (PNG/SVG, max 500 KB)
  • Footer text (payment terms, notes)
  • Currency display (USDT or USD equivalent)

API: Fetch an Invoice

GET /api/v1/invoices/{invoiceId}
Accept: application/pdf

// Response: PDF binary stream
Content-Type: application/pdf
Content-Disposition: attachment; filename="INV-1042.pdf"

What's Included in the Invoice

  • Invoice number (auto-incrementing, prefix configurable)
  • Issue date and due date
  • Merchant and customer details
  • Line items with USDT amounts
  • Transaction hash (clickable BSCScan link)
  • Network and confirmation block number
  • Platform fee breakdown

Auto-Send on Payment

Enable Auto-send invoice on payment in settings to automatically email the PDF to the customer's email address when the deposit_detected event fires.

Accounting System Export

Bulk-export invoices as a ZIP archive via:

GET /api/dashboard/invoices/export?from=2025-01-01&to=2025-12-31&format=zip
