This application is designed to allow the creation of signed electronic invoices as per Guatemalan requirements through an Electronic Invoice Generation Service Provider (EIGSP). Many local companies offer Electronic Invoice Generation services through their own web portals, which despite the advantages of using signed electronic invoices (little or no paper usage), make it cumbersome to keep records centralized and unified. Any company operating their accounting, stock and price lists on their own enterprise management software will have to manually duplicate data entry on the EIGSP web portal if they already have an accounting system. This makes it cumbersome and time consuming to keep records centralized and unified. This application aims to resolve this, building upon ERPNext's existing Sales Invoice DocType, greatly automating the process of generating a Signed Electronic Invoice.
- Easily generate an electronic invoice with the click of a button. Adds only one step to the workflow for managing Sales Invoices.
- Minimal dialog generation: Only serious errors will generate dialogs.
- Simple error management: You either generate the electronic invoice or you don't. Errors in dialogs will point you in the right direction for fast resolution.
- Separate Application Icon on the Desk (can hide it if desired)
- Stores several configurations, only one configuration allowed to be active.
- Keeps individual transaction data for each invoice generated (for auditing and verification purposes)
- Allows you to match EIGSP DocTypes with your ERPNext DocTypes based on the Naming Series prefix through a dropdown menu. The application will rename the Invoice upon obtaining the officially generated number, and it will update all transactions referring to it: (Stock Entry, GL Entry, etc.)
- Allows you to enter the required three digit alphanumeric UOM codes required by the EIGSP and tax authority, directly on the Unit of Measure DocType. It loads it automatically when creating an Item.
- Given the problem of ERP software of providing a precise rounding amount, a field was added to Purchas eand Sales Invoice Items where the user enters the Invoice amount resulting from quantity x rate. This triggers the goalSeek js library that has been incorporated, to iterate through 10,000 options of decimals for the quantity, without altering the rate, so that the amount is properly estimated to the amount printed on the physical invoice being entered (This is useful when entering pre-existing invoice copies for accounting purposes only). Please see the Wiki “Item amount back calculation” for details.
These features were added because they are a requirement for each electronic invoice to notify if any excise taxes are present.
- Configure excise taxes on a per item basis (Tax per Unit of Measure).
- Specify the account on which the excise tax for a Sales Invoice or a Purchase Invoice will be tallied.
- Automatically estimate and account for the correct taxes when items with excise taxes are present on the Sales or Purchase Invoices
- Automatically sets the pre-configured account for recording excise taxes for Sales and Purchase invoices.
- Given the compliance needed for excise taxes such as fuel, tobacco, alcohol, cement, and others, each Item now has three checkboxes to specify if item is fuel, a good or a service. This division allows local accountants to generate a purchase book (Libro de Compras) in the format specified by the local tax authority (SAT), by using these selectors to categorize individual items in the Sales Invoice, adding each category properly, estimating their sales tax, net of excise tax properly, and then simply showing these totals in a Sales Invoice report with the proper fields (columns) chosen. Please see our Wiki page on configuring this report.
- You can now generate elctronic invoices in other currencies allowed by Guatemala's SAT: USD
- Massive electronic invoice generation: Some users have a monthly process that requires them to generate more than 100 invoices per ocurrence. To automate this task, we added a massive generation feature, allowing you to load required invoices using a pre-formatted spreadsheet file, initiate the generation or electornic signing process, and keep a log. More info on that page. TK
We opted to combine planned tax functionality from our dedicated tax app into this one for faster development so we have added the following improvements to the existing functionality:
- Purchase Ledger: A customized purchase ledger report and print format have been added. This purchase ledger is configured to satisfy the requirements of tax authorities in Guatemala.
- Sales Ledger: A customized sales ledger report and print format have been added. This sales ledger is configured to satisfy the requirements of tax authorities in Guatemala.
- Purchase and Sales Tax Declaration ("Asiste Libros"): A report combining both purchases and sales with the required categorization by tax authorities has been added. You can generate a monthly VAT tax declaration directly from this report, delivered as an .asl file (a kind of CSV using Pipes as column separators), and keep a log of which invoices have been declared. This allows you to add invoices extemporaneously as permitted by law and include them in future declarations up two months before the month of the declaration. More details here.
- VAT Tax Conciliation: A report combining the VAT tax payable and VAT tax receivable to clarify whether you need to pay VAT tax or not for the requested period.
- VAT and Income Tax Retention Report: Tax rules in Guatemala require withholding tax payments depending on tax category matching between company and supplier. This report allows you to keep track of which retentions exist for both purchase and sales invoices. Functionality in the actions button for both sales and purchase invoices allows for creation of these new doctypes, and journal entries with automated calculations of how much is retention and the liquid payment (Cash, Check, etc).
- Consumable Acquisition Document Report: Similar to the tax retention report, export companies are allowed to claim tax credit on production items. The Consumable Acquisition Record and its report, allow the user to keep track of the invoices that have this document linked. Functionality in the actions button for purchase invoices allows for creation of these new doctypes, and journal entries with automated calculations of the consumable acquisition record portion and the liquid payment (Cash, Check, etc).
- As a support feature for all the previously mentioned reports, a special section was added that allows the specification of accounts, rates and lower and uppper limits for VAT retentions and income tax retentions.
An account with monthly service with any of the supported EIGSP companies is required for this application to work. Such a service costs approximately $40 a month as of 2020. Only one company supported currently.
To install this application, you must have ERPNext up and running. Please note: This will only work in self-deployed instances of ERPNext installations as of February 2018. Work is underway to bring the excise tax portion to the ERPNext software core.

About the Taxpayer ID number or NIT of the customer who is issued a Sales Invoice, Credit Note or Debit Note. Guatemalan taxpayer ID numbers follow the format of alphanumeric digits followed by a check digit, also alphanumeric, which is conventionally represented by separating the check digit with a dash character: "-" Recently we had a case of a customer of our client requiring the dash to accept the invoice as valid.
Upon consultation with a representative of the Guatemalan Tax Authority, on May 16, 2018, the representative categorically confirmed that the dash does not form part of the Taxpayer ID number, and recognizes it only as a convention.
This means that legally or commercially, these two forms of rendering the Tax ID (NIT) are the one and the same:
1234567-8 12345678
Users who issue electronic invoices can rest assured, that the manner in with the Tax ID is rendered within ERPNext is legally correct despite not having the "-" dash character.
The PDF generated by the third-party electronic invoice generator service provider, to which our software links from a Valid and Electronic Generated Invoice within ERPNext, is assured to be legally correct, because the third-party service provider is obligated to furnish this data in compliance with the law. An electronic invoice will not be generated by the third-party service provider if any data furnished by our app form within ERPNext is not correct.
Sobre el Número de identificación Tributaria (NIT) del cliente al que se le emite Factura Electrónica, Nota de Credito o Nota de Débito. Los Números de identificación Tributaria del cliente en Guatemala siguen el formato de digitos alfanuméricos seguidos de un dígito de chequeo, también alfanumérico, el cual se representa convencionalmente con separar el dígito de chequeo al final del Número de identificación Tributaria con un guión o "-". Recientemente hemos tenido un caso de un cliente de uno de nuestros clientes, que requirió el guión para aceptar como válida la factura electrónica.
Después de varias consultas de verificación y en una llamada telefónica con un agente de la Superintendencia de Administración Tributaria el 16 de Mayo de 2018, el representante confirmó enfáticamente que el guión no forma parte oficial de Número de identificación Tributaria, y lo reconoce solamente como una convención.
Esto implica, que legalmente y comercialmente, estas dos formas de mostrar o imprimir el Número de identificación Tributaria son iguales:
1234567-8 12345678
Los usuarios que emiten facturas electrónicas o cualquier Documento Tributario Electrónico, pueden estar tranquilos, que la manera en que se muestra el Número de identificación Tributaria de las partes, esta legalmente correcto aunque no muestre el guión "-".
El PDF generado por el proveedor de servicios de Generación de Factura Electrónica. The PDF generated by the third-party electronic invoice generator service provider, to which our software links from a Valid and Electronic Generated Invoice within ERPNext, is assured to be legally correct, because the third-party service provider is obligated to furnish this data in compliance with the law. An electronic invoice will not be generated by the third-party service provider if any data furnished by our app form within ERPNext is not correct.
