How does DDA capture work?

DDA is Brazil's electronic register of the boletos issued against a CNPJ. Boletos registered to the connected CNPJs are identified through DDA and arrive with payee, amount and due date, depending on the integration. They land in the same inbox as the documents, to be matched to the invoice and the obligation.

Does DDA make the payment?

No. DDA shows the boletos issued against your CNPJ; it doesn't pay or debit anything. Capturing a charge isn't approving it either. Payment is a separate step, authorized at the bank or through the bank integration.

Can I link an invoice, a bill and a boleto?

Yes. The invoice, bill and boleto for the same purchase form one obligation. The link is checked before posting, so the same amount doesn't become two payables in the ERP.

What if the reading finds incomplete data?

The missing field stays blank and flagged for review. It's never filled in as if it had been read. Data filled in from records, and suggestions, are labeled as such.

How do reviews and approvals work?

Whatever the checks don't confirm, or whatever the rule says to review, reaches the owner with the reason and the documents. The decision stays in the history, and the flow follows it. Approval rules are defined with the Openi team during onboarding.

How does the data reach the ERP?

The record is built in the format the ERP accepts, such as a payable with the reference document, and sent through the integration. It only counts as posted when the ERP confirms it; a refusal comes back with the system's response.

Can I track several companies?

Yes. Each document is tagged with the company it belongs to, and the inbox filters by company, source and status, without mixing one CNPJ's data with another's.

How does the new tax reform data enter the flow?

The IBS, CBS and Selective Tax groups from Brazil's tax reform arrive in received documents according to the layouts in force, are kept with the document and move on to the systems that use them. Openi doesn't do your full tax calculation or guarantee credits.

The routine today

Receiving the fileis only the start.

Once the document arrives, someone still has to figure out what it is, check it, find what it relates to, get it approved and post it. That's where the routine drags.

DDA isn't direct debit.
DDA shows the boletos issued against your CNPJ. Nothing is debited from the account because of it.

Once obtained, the tax document is where checking starts: who issued it, to whom, what was bought, for how much, and what it relates to in the operation.

Boletos, invoices and bills

Charges and recurring expenseswith the context to check them.

An invoice, a bill and a boleto can be parts of the same obligation. Treating each one as a separate record is how accounts payable ends up with duplicates.

The boleto says how much and when to pay. It needs the document that says why.

From checking to posting

Check, route and postwithout losing the history.

The same document goes through all four stages. Each one shows what was checked, who decided and what the destination system answered.

01 · Check
Checks before anything is posted.
Fields, records, amounts and links checked against the rules you configure.
Document checking isn't tax validation: it confirms the document is complete and consistent with the operation, not how it's classified for tax.

Tax reform and data

Organize data and evidenceas Brazilian taxes change.

With Brazil's tax reform, received documents start carrying IBS, CBS and the Selective Tax. For finance, accounting and tax teams, what matters is getting that data complete, keeping the original document and delivering each piece of information to whoever uses it.
