IBS and CBS on every tax document
It applies to Simples Nacional and MEI as well. PIS and Cofins end and CBS takes their place, with base, rate and amount shown per line on the invoice.
Management software for small Brazilian companies
Sales, stock, finance and tax documents
in the same system.
Guidis ERP is Guidi Sistemas' management software. It covers the order, the invoice, tax document issuing, stock and accounts payable and receivable, with the data coming from a single place. Implementation is done by our team, together with yours and with your accountant.
Brazilian tax reform
Dates already set in law
Assessment moves to the document level
EFD-Contribuições stops accepting new facts. The tax authority starts delivering the IBS and CBS assessment by the 15th of the following month, for the taxpayer to review and confirm.
The option to pay outside the DAS
A Simples Nacional company may choose to pay IBS and CBS outside the DAS, which gives its business customers full credit. The choice is made twice a year and cannot be undone within the semester.
Dates and rules per Complementary Law 214/2025 and CGSN Resolution 194/2026. The CBS reference rate depends on the Senate and the split of the DAS across taxes depends on the Simples Nacional committee. Where the number has not been published, our guides say so instead of estimating.
Who it is for
The three profiles we serve today
Services
Service invoices, contracts, accounts receivable and reconciliation of what reached the bank.
Retail with a store
Counter sales, stock written down on issuing, and till closing at the end of the day.
B2B trade and distribution
Orders, invoicing, purchase intake from the supplier XML, and pricing per payment terms.
We do not serve MEI, restaurants and delivery (we have a dedicated product for food service), manufacturing with production planning, or e-commerce that depends on dozens of marketplaces.
What it does
What the system covers today
Selling, invoicing and tax documents
The order becomes an invoice, and the invoice becomes a receivable. NF-e and NFC-e are issued inside the system, with a fallback when the tax authority does not respond.
Stock
Balances come from movements, with average cost per branch. Purchase intake is done from the supplier XML.
Finance and collection
Payables and receivables, boleto and Pix collection tied to the invoice, bank statement reconciliation, and a P&L by period.
Predictable pricing
Increases capped at inflation, the same price list for new and existing customers, and monthly billing with no cancellation penalty.
Who builds it
Guidi Sistemas, management software since 2010
We have built management software, point of sale and tax document issuing for small and mid-sized companies for more than 16 years, in Rio de Janeiro. Support is handled by the team that develops the system.
Besides the ERP, we run products for tax filing obligations and for public company data, used by companies and accounting firms.
About the companyHow it starts
Assisted implementation, limited slots per month
Implementation is done by our team together with yours: migrating records and balances, setting up your operation and following the first invoices you issue, with your accountant in the conversation. Each implementation takes one of our people for several days, so we take a limited number of companies per month.

Frequently asked questions
What people ask before talking to us.
How much does it cost?
It depends on which modules the company uses, how many companies you run and how many tills the store has. We go through the numbers in the implementation conversation. Increases are capped at inflation and the price list is the same for new and existing customers.
Why is there a queue?
Because implementation is assisted: someone from our team migrates the data, sets up the operation and follows the first invoices. That takes several days per customer, which limits how many companies start each month.
Can you migrate what is in my current system?
Migration is part of the implementation. We map where each piece of information comes from (records, stock balances, open receivables) and what is worth bringing. We usually bring records and balances you have checked, rather than the whole history.
Does my accountant take part?
Yes. They know the company tax regime and the obligations that close every month, so they take part from the first conversation.
How do you handle the tax reform?
We have been following the published rules since 2026, and our guides explain what changes, with a source for every fact. In the implementation conversation we look at your case, including whether to pay IBS and CBS inside or outside the DAS.
Do you serve companies outside Rio de Janeiro?
Yes. Implementation and support are remote, and tax document issuing follows the Brazilian national standard.
