*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.*
