  • Generate the payment complement (REP) when you collect in installments or on credit
  • Cancel with acknowledgment and cancellation reason per SAT rules
  • Download the XML and the PDF with printable representation from the same detail
El Salvador

  • Sign and transmit the DTE online and receive Hacienda's seal
  • Issue a tax credit document for customers that report IVA
  • Generate credit and debit notes linked to the original document
  • Operate in contingency mode and transmit later when the connection returns
Error-free

Data that fills itself in

Lumon pulls the products, prices, and taxes from your catalog and the customer's tax data to build the document. Less manual entry means fewer rejections and fewer corrections at month-end.

  • Preload the customer's tax data from their profile
  • Calculate IVA, withholdings, and tax breakdown automatically
  • Apply the correct product or service key and unit of measure
  • Reuse templates for your most-invoiced products and services
