Monthly MX+ release: Efficientix's tax and operations localization for Oracle NetSuite in Mexico.

During March, improvements were released for payment and advance payment management, document generation, customs declaration control, addenda and self-service flows.

Basic

Advance payments and payments

  • Fixed advance payment calculations in tax-exempt operations so the available and applied amounts are consistent.
  • The payment complement better handles credit notes and the separation of tax bases and rates.

PDF templates

  • Improved the presentation of invoices and the information required in tax and foreign trade scenarios.
  • Templates v1 and v2 can be kept as separate options, so an update no longer replaces the format you chose.

Pro

Addenda and Customs Declarations

  • The NETO addendum calculates boxes, units and unit price more consistently from the transaction data.
  • Improved the assignment of available customs declarations to pending invoices.
  • Expanded and stabilized addenda coverage for different business scenarios.

Premium

Global Invoice

  • Improved the consistency of the process and the link between the global invoice and its individual invoices.

Supplier Portal

  • Enabled uploading XML and PDF files and creating vendor bills when there is no associated purchase order.
  • Added a validation to prevent uploading documents with a duplicate UUID.

The availability of each improvement depends on the modules enabled in your account.
