AddTax Inbound/Outbound

Grupo 3

AddTax is a system designed to automate the receipt of electronic tax and non-tax documents. With the purpose of improving processing flows and streamlining the management of electronic tax documents, in order to mitigate possible problems in receipt. The solution was developed according to the best market practices, following the SAP architecture.

NF-e I Electronic invoice

The Electronic Invoice is a digital document, required by the federal government, which aims to document operations for the circulation of goods or the provision of services. In addition, the NF-e is valid in all states of the Federation.

Input Automation

The use of the Electronic Invoice makes commercial transactions among companies, as well as the delivery of goods, controlled by the Tax Authorities. Add Tax automates the entry of NF-e documents, in a fully configurable way, complying with the SAP Standard and the specific processes of each segment, thus facilitating their management.

  • Issuance of Electronic Invoices

The AddTax NF-e Outbound module has the ability to carry out the document issuance process according to the SAP standard being carried out by the user himself or by prescheduled transactions.

CT-e I Electronic Bill of Lading

More agility and safety for companies that carry out cargo and material transport activities.

This module of the AddTax solution was developed to assist the issuance of CT-e of companies that carry out the transport of loads and materials. The process is carried out entirely in a SAP environment and with the possibility of integration with Sefaz (Secretariat of Finance), using a middleware that best suits the company’s needs.

Electronic Bill of Lading

The solution allows the electronic sending and receiving of the CT-e, already validated by Sefaz, in accordance with current requirements. You can also store, scan and manage documents at any time. Finally, the system allows the unification of data related to information issued by carriers.

Secure Storage

Thanks to 100% SAP technology, storage is carried out safely, with digital certificate and distributed printing. Our solution also meets the conceptual model for issuing and receiving invoices established by the Brazilian Association of Capital Finance Secretariats (Abrasaf), which standardizes the NF-e communication mechanism in the country.

  • Issue of NFS-e

The issuance of Electronic Service Invoices is done in SAP ECC, according to the sales orders already invoiced and after the Invoice is issued (Jl B3n). The layout model varies according to each Municipality, so it is used according to their integration manuals.

  • NFS-e Reception

The reception of electronic files (XML) can be carried out by e-mail or upload, depending on the availability of each municipality, in zipped or separate files. Our solution is also able to receive documents in TXT (text), PDF, JPEG and city hall link format in the body of the email, leading to an HTML file.

MD-e I Manifestation of the Electronic Recipient

The Recipient’s Manifestation allows the recipient of the electronic Invoice to manifest itself in relation to an NF-e issued to its CNPJ. Our solution allows the information of the notes to be manifested to be obtained through a search of the national environment database, by importing the XML file or through the access key.

Awareness of the Issue and Operation Confirmation

The first event, Awareness of the Issue, is optional and can be performed to declare that the recipient knows about the existence of the issue described in the NF-e, but still does not have enough elements to present a conclusive statement.

The second, Operation Confirmation, exists to confirm the occurrence of the operation described in the Electronic Invoice and the receipt of the goods.

  • Operation not performed

In this manifestation, the recipient can declare that the operation described in the NFe was requested, but did not take place. Processing can be done by the operation user or pre-scheduled transactions.

  • Ignorance of the operation

The recipient may declare, in this manifestation option, that the operation described in the electronic Invoice was not requested by him. In this case, the XML message will be signed with a digital certificate that has the author’s CNPJ.

Purpose of MDF-e

Our solution aims to speed up the batch registration of tax documents in transit and identify the cargo unit used and other transport characteristics. Bearing in mind that the authorization to use the MDF-e will imply a subsequent registration of the events, in the related electronic tax documents.

  • Issuance of MDF-e

The Declaration of the Recipient of Tax Documents must be issued by companies providing transport services or by other companies involved in the operations, that the transport is carried out in their own, leased vehicles, or by contracting an autonomous cargo carrier, with more than one invoice.
