The Peruvian localization has been improved and extended, in this version the next modules are available:

  • l10n_pe: Adds accounting features for the Peruvian localization, which represent the minimal configuration required for a company to operate in Peru and under the SUNAT regulations and guidelines. The main elements included in this module are: Chart of account, taxes, document types.

  • l10n_pe_edi: includes all technical and functional requirements to generate and validate Electronic Invoice, based on the SUNAT specification to create and process valid electronic documents, for more technical detail you can access the SUNAT EDI specifications, that keeps track of new changes and updates. The features of this module are based on the resolutions published on the SUNAT Legislation.


Install the Peruvian localization modules

Go to Apps and search for Peru, then click Install in the module Peru EDI. This module has a dependency with Peru - Accounting. In case this last one is not installed, Odoo installs it automatically within EDI.

The "Module" filter is set on "Peru"


When you install a database from scratch selecting Peru as country, Odoo automatically installs the base module: Peru - Accounting.

Configure your company

In addition to the basic information in the Company, we need to set Peru as the Country, this is essential for the Electronic Invoice to work properly. The field Address Type Code represents the establishment code assigned by the SUNAT when companies register their RUC (Unique Contributor Registration):

Company data for Peru including RUC and Address type code


In case the Address type code is unknown, you can set it as the default value: 0000. Be aware that if an incorrect value is entered, the Electronic invoice validation might have errors.


The NIF should be set following the RUC format.

Chart of Account

The chart of accounts is installed by default as part of the set of data included in the localization module, the accounts are mapped automatically in:

  • Taxes

  • Default Account Payable.

  • Default Account Receivable

The chart of accounts for Peru is based on the most updated version of the PCGE, which is grouped in several categories and is compatible with NIIF accounting.

Accounting Settings

Once the modules are installed and the basic information of your company is set, you need to configure the elements required for Electronic Invoice. For this, go to Accounting ‣ Settings ‣ Peruvian Localization.

Basic Concepts

Here are some terms that are essential on the Peruvian localization:

  • EDI: Electronic Data Interchange, which in this refers to the Electronic Invoice.

  • SUNAT: is the organization that enforces customs and taxation in Peru.

  • OSE: Electronic Service Operator, OSE SUNAT’s definition.

  • CDR: Receipt certificate (Constancia de Recepción).

  • SOL Credentials: Sunat Operaciones en Línea. User and password are provided by the SUNAT and grant access to Online Operations systems.

Signature Provider

As part of the requirements for Electronic Invoice in Peru, your company needs to select a Signature Provider that will take care of the document signing process and manage the SUNAT validation response. Odoo offers three options:

  1. IAP (Odoo In-App Purchase)

  2. Digiflow

  3. SUNAT

Please refer to the sections below to check the details and considerations for each option.

IAP (Odoo In-App Purchase)

This is the default and the suggested option, considering the digital ceritificate is included as part of the service.

IAP option as signature providers
What is the IAP?

This is a signature service offered directly by Odoo, the service takes care of the next process:

  1. Provides the Electronic invoice Certificate, so you do not need to acquire one by yourself.

  2. Send the document to the OSE, in this case, Digiflow.

  3. Receive the OSE validation and CDR.

How does it work?

The service requires Credits in order to process your electronic documents. Odoo provides 1000 credits for free in new databases. After these credits are consumed, you need to buy a Credit Package.











The credits are consumed per each document that is sent to the OSE.


If you have a validation error and the document needs to be sent one more time, one additional credit will be charged. Therefore, it is paramount that you verify all information is correct before sending your document to the OSE.

What do you need to do?
  • In Odoo, once your enterprise contract is activated and you start working in Production, you need to buy credits once the first 1000 are consumed.

  • As Digiflow is the OSE used in the IAP, you need to affiliate it as the official OSE for your company on the SUNAT website. This is a simple process. For more information, please check OSE Affiliation guide.

  • Register Digiflow as the authorized PSE, please check PSE Affiliation guide.


This option can be used as an alternative, instead of using the IAP services you can send your document validation directly to Digiflow. In this case you need to consider:

  • Buy your own digital Certificate: For more detail regarding the official vendor list, and the process to acquire it, please refer to SUNAT Digital Ceritifcates.

  • Sign a service agreement directly with Digiflow.

  • Provide your SOL credentials.


In case your company wants to sign directly with the SUNAT, it is possible to select this option in your configuration. In this case you need to consider: - Get the SUNAT Certification process accepted.

  • Buy your own digital Certificate: For more detail regarding the official vendor list, and the process to acquire it, please refer to SUNAT Digital Ceritifcates.

  • Provide you SOL credentials.


When using direct connection with the SUNAT, the SOL User must be set with the Company RUT + User Id. Example: 20121888549JOHNSMITH

Testing environment

Odoo provides a testing environment that can be activated before your company goes into production.

When using the testing environment and the IAP signature, you don’t need to buy testing credits for your transactions as all of them are validated by default.


By default the databases are set to work on production, make sure to enable the testing mode if needed.


In case you don’t use Odoo IAP, in order to generate the electronic invoice signature, a digital certificate with the extension .pfx is required. Proceed to this section and load your file and password.

EDI Certificate wizard


The official currency exchange rate in Peru is provided by the Bank of Peru. Odoo can connect directly to its services and get the currency rate either automatically or manually.

Bank of Peru is displayed in Multicurrency Service option

Please refer to the next section in our documentation for more information about multicurrencies.

Configure Master data


As part of the localization module the taxes are created automatically with their related financial account and electronic invoice configuration.

List of default taxes
EDI Configuration

As part of the taxes configuration, there are three new fields required for electronic invoice, the taxes created by default have this data included, but in case you create new taxes make sure you fill in the fields:

Taxes EDI data for Peru

Fiscal Positions

There are two main fiscal positions included by default when you install the Peruvian localization.

Extranjero - Exportación: Set this fiscal position on customers for Exportation transactions.

Local Peru: Set this fiscal position on local customers.

Document Types

In some Latin American countries, including Peru, some accounting transactions like invoices and vendor bills are classified by document types, defined by the government fiscal authorities, in this case by the SUNAT.

Each document type can have a unique sequence per journal where it is assigned. As part of the localization, the Document Type includes the country on which the document is applicable;the data is created automatically when the localization module is installed.

The information required for the document types is included by default so the user does not need to fill anything on this view:

Document Type list


Currently the documents supported on customer invoices are: Invoice, Boleta, Debit Note and Credit Note.


When creating Sales Journals, the following information must be filled, in addition to the standard fields on the Journals:

Use Documents

This field is used to define if the journal uses Document Types. It is only applicable to Purchase and Sales journals, which are the ones that can be related to the different set of document types available in Peru. By default, all the sales journals created use documents.

Electronic Data Interchange

This section indicates which EDI workflow is used in the invoice, for Peru we must select “Peru UBL 2.1”.

Journal EDI field


By default, the value Factur-X (FR) is always displayed, make sure you can uncheck it manually.


Identification Type and VAT

As part of the Peruvian localization, the identification types defined by the SUNAT are now available on the Partner form, this information is essential for most transactions either on the sender company and in the customer, make sure you fill in this information in your records.

Partner identification type


Additional to the basic information in your products, for the Peruvian localization, the UNSPC Code on the product is a required value to be configured.

UNSPC Code on products

Usage and testing

Customer invoice

EDI Elements

Once you have configured your master data, the invoices can be created from your sales order or manually. Additional to the basic invoice information described on our page about the invoicing process, there are a couple of fields required as part of the Peru EDI:

  • Document type: The default value is “Factura Electronica” but you can manually change the document type if needed and select Boleta for example.

    Invoice document type field on invoices
  • Operation type: This value is required for Electronic Invoice and indicates the transaction type, the default value is “Internal Sale” but another value can be selected manually when needed, for example Export of Goods.

    Invoice operation type field on invoices
  • EDI Affectation Reason: In the invoice lines, additional to the Tax there is a field “EDI Affectation Reason” that determines the tax scope based on the SUNAT list that is displayed. All the taxes loaded by default are associated with a default EDI affection reason, if needed you can manually select another one when creating the invoice.

    Tax affectation reason in invoice line

Invoice validation

Once you check all the information in your invoice is correct, you can proceed to validate it. This action registers the account move and triggers the Electronic invoice workflow to send it to the OSE and the SUNAT. The following message is displayed at the top of the invoice:

Sending of EDI Invoice in blue

Asynchronous means that the document is not sent automatically after the invoice has been posted.

Electronic Invoice Status

To be Sent: Indicates the document is ready to be sent to the OSE, this can be done either automatically by Odoo with a cron that runs every hour, or the user can send it immediately by clicking on the button “Sent now”.

Send EDI manually

Sent: Indicates the document was sent to the OSE and was successfully validated. As part of the validation a ZIP file is downloaded and a message is logged in the chatter indicating the correct Government validation.

Message on chatter when the invoice is valid

In case there is a validation error the Electronic Invoice status remains in “To be sent” so the corrections can be made and the invoice can be sent again.


One credit is consumed each time that you send a document for validation, in this sense if an error is detected on an invoice and you send it one more time, two credits are consumed in total.

Common Errors

There are multiple reasons behind a rejection from the OSE or the SUNAT, when this happens Odoo sends a message at the top of the invoice indicating the error details and in the most common cases a hint to fix the issue.

If a validation error is received, you have two options:

  • In case the error is related to master data on the partner, customer or taxes, you can simply apply the change on the record (example customer identification type) and once it is done click on the Retry button.

  • If the error is related to some data recorded on the invoice directly (Operation type, missing data on the invoice lines), the correct solution is to reset the invoice to Draft, apply the changes, and then send the invoice again to the SUNAT for another validation.

    List of common errors on invoices

For more detail please refert to Common errors in SUNAT.

Invoice PDF Report

After the invoice is accepted and validated by the SUNAT, the invoice PDF report can be printed. The report includes a QR code, indicating the invoice is a valid fiscal document.

Invoice PDF report

IAP Credits

Odoo’s Electronic IAP offers 1000 credits for free, after these credits are consumed in your production database, your company must buy new credits in order to process your transactions.

Once you run out of credits a red label is displayed at the top of the invoice indicating that additional credits are required, you can easily buy them by accessing the link provided in the message.

Buying credits in the IAP

In the IAP service includes packages with different pricing based on the number of credits. The price list in the IAP is always displayed in EUR.

Special Use cases

Cancellation process

Some scenarios require an invoice cancellation, for example, when an invoice was created by mistake. If the invoice was already sent and validated by the SUNAT, the correct way to proceed is by clicking on the button Request Cancellation:

Request invoice cancellation button

In order to cancel an invoice, please provide a cancellation Reason.

Electronic Invoice Status

To Cancel: Indicates the cancellation request is ready to be sent to the OSE, this can be done either automatically by Odoo with a cron that runs every hour, or the user can send it immediately by clicking on the button “Send now”. Once it is sent, a cancellation ticket is created, as a result the next message and CDR File are logged in the chatter:

Cancellation CDR sent by the SUNAT

By default the Debit Note is set in the document type.

Electronic delivery guide 2.0

The Guía de Remisión Electrónica (GRE) is an electronic document generated by the shipper to support the transportation or transfer of goods from one place to another, such as a warehouse or establishment. In Odoo, there are several configuration steps needed before you can successfully use this feature.

The use of the guía de remisión electrónica electronic document is mandatory and required by SUNAT for taxpayers who need to transfer their products, except those under the Single Simplified Regime (régimen único simplificado or RUS).

Delivery guide types


The Sender delivery guide type is issued when a sale is made, a service is rendered (including processing), goods are assigned for use, or goods are transferred between premises of the same company and others.

This delivery guide is issued by the owner of the goods (i.e., the sender) at the beginning of the shipment. The sender delivery guide is supported in Odoo.


The Carrier delivery guide type justifies the transportation service the driver (or carrier) performs.

This delivery guide is issued by the carrier and must be issued to each shipper when the shipment goes through public transport.


The carrier delivery guide is not supported in Odoo.

Transportation types


The Private transportation type option is used when the owner transfers goods using their own vehicles. In this case, a sender’s delivery guide must be issued.


The Public transportation type option is used when an external carrier moves the goods. In this case, two delivery guides must be issued: the sender’s delivery guide and the carrier’s delivery guide.

Direct submission to SUNAT

The creation of the GRE delivery guide in Odoo must be sent directly to the SUNAT, regardless of the electronic document provider: IAP, Digiflow, or SUNAT.

Required information

Version 2.0 of the electronic delivery guide requires additional information on the general configuration, vehicles, contacts, and products. In the general configuration, it is necessary to add new credentials that you can retrieve from the SUNAT portal.


Both the sender and the carrier can cancel the electronic waybill as long as the following conditions are met:

  • The shipment has not been initiated.

  • If the shipment has been initiated, the receiver must be changed before reaching the final destination.


The SUNAT no longer uses the term “Anula”, but now uses the term “Dar de baja” for cancellations.


The SUNAT does not support a test environment. This means that any delivery guides that were generated by mistake will be sent to the SUNAT.

If, by mistake, the waybill was created in this environment, it is necessary to delete it from the SUNAT portal.



  • Electronic sender’s GRE is currently the only supported type of waybill in Odoo.

  • The delivery guide is dependent on the Odoo Inventory app, the l10n_pe_edi and l10n_pe modules.

  • A second user must be added for the creation of electronic documents.

After following the steps to configure the electronic invoicing and the master data, install the Peruvian - Electronic Delivery Note 2.0 module (l10n_pe_edi_stock_20).

Next, you need to retrieve the client ID and client secret from SUNAT. To do so, follow the manual de servicios web plataforma nueva GRE.


In the SUNAT portal, it is important to have the correct access rights enabled, as they may differ from the user set for electronic invoicing.

These credentials should be used to configure the delivery guide general settings from Accounting ‣ Configuration ‣ Settings ‣ Peruvian Electronic Invoicing.

Example for the SUNAT Delivery Guide API section configuration.


It is required to follow the format RUC + UsuarioSol (e.g., 20557912879SOLUSER) for the Guide SOL User field, depending on the user selected when generating the GRE API credentials in the SUNAT portal.


The operator is the vehicle’s driver in cases where the delivery guide is through private transport.

To create a new operator, navigate to Contacts ‣ Create and fill out the contact information.

First, select Individual as the Company Type. Then, add the Operator License in the Accounting tab of the contact form.

Once the transfer form is correctly validated by SUNAT, the generated XML file becomes available in the chatter. You can now print the delivery slip that shows the transfer details and the QR code validated by SUNAT.

Transfer details and QR code on generated delivery slip.

Common errors

  • Diferente prefijo para productos (T001 en algunos, T002 en otros)

    At the moment, Odoo does not support the automation of prefixes for products. This can be done manually for each product output. This can also be done for non-storable products. However, keep in mind that there will be no traceability.

  • 2325 - GrossWeightMeasure - El dato no cumple con el formato establecido "Hace falta el campo" "Peso"" en el producto

    This error occurs when the weight on the product is set as 0.00. To fix this, you need to cancel the waybill and recreate it. Make sure that you fix the weight on the product before creating the new waybill, or it will result in the same error.

  • JSONDecodeError: Expecting value: line 1 column 1 (char 0) when creating a Delivery Guide

    This error is typically generated due to SOL user issues. Verify the user’s connection with the SUNAT; the SOL user must be established with the company RUT + user ID. For example 2012188549JOHNSMITH.

  • El número de documento relacionado al traslado de mercancía no cumple con el formato establecido: error: documento relacionado

    The Related Document Type and Related Document Number fields only apply to invoices and receipts.

  • 400 Client error: Bad Request for URL

    This error is not solvable from Odoo; it is advised you reach out to the SUNAT and verify the user. It may be necessary to create a new user.

  • Invalid content was found starting with element 'cac:BuyerCustomerParty'

    This error occurs when the transfer reason is set as other. Please select another option. Following to the official documentation of the SUNAT’s waybill guide, the transfer reasons 03 (sale with shipment to third party) or 12 (others) does not work in Odoo, since you should not have an empty or blank customer.

  • Duda cliente: consumo de créditos IAP al usar GRE 2.0

    For live clients using IAP, no credit is consumed (in theory) because it does not go through the OSE, i.e., these documents are directly sent to the SUNAT.

  • Errores con formato credenciales GRE 2.0 (traceback error)

    Odoo currently throws an error with a traceback instead of a message that the credentials are not correctly configured in the database. If this occurs on your database, please verify your credentials.
