Abstra
    By department · Tax

    Tax receives invoices all day long. And it still depends on one person's head.

    Abstra captures the tax document, classifies it with AI, calculates the tax by rule and talks to the tax authority, municipalities and your ERP, even where there is no API. Auditable, and ready for the tax reform.

    The tax pipeline

    1Capture

    Invoices, tax slips and bills by email/portal

    2Classify

    Transaction code, operation nature, tax situation and rule validation

    3Calculate

    State/city/federal taxes and withholdings with deterministic calculation

    4File

    Filing, tax authority, municipality, SPED and ERP posting

    Exceptions do not block: an ambiguous case goes to human review and returns to the flow. Underneath it all: audit, dedup and a shield against fines.

    If your tax process looks like this, we fix it.

    I receive invoices by email all day long and someone has to download, read and type each one in.
    Finding the right transaction code / operation nature depends on one specific person's head.
    Matching what was filed against what was paid takes hours every month.
    The municipal portal has no API: it's manual login, captcha, one at a time.

    Tax BPO

    Tax-slip vs. tax-return matching via OCR (corporate income tax), with a discrepancy report.

    Industrial company / holding

    Generates the corporate tax return's Block M: reads the income-tax spreadsheet and produces the file in the tax authority's layout.

    Data

    Tax ID · BrasilAPI · Excel/Sheets · databases

    AI reads the invoice. The tax rule calculates the tax. The connector talks to the tax authority and the ERP. Portals without an API and positional SPED files do not come out of a chat.

    Why not generic AI?

    Frequently asked questions

    Does it work with municipalities that have no API?+

    Yes. We use RPA/browser agents when the portal requires login and captcha, with a trail of what was downloaded and issued.

    Does transaction-code classification stay in someone's head?+

    It becomes a versioned rule. Ambiguous cases go to human review and the learning returns to the pipeline.

    Are you ready for the tax reform?+

    The pipeline is built to change rules and connectors without redesigning the whole process. Start with the highest-volume flows now.

    Where should we start?+
