How we work

We build software to take useless work out of accounting firms.

Mastro builds software for Italian accounting firms. We start from real workflows, work with the tools the firm already uses and leave the decisions that need judgement to the professional.

What we do

We connect documents, communications, deadlines and accounting work to cut manual steps and re-checks.

What we don’t do

We don’t promise a firm without people, we don’t replace the accounting software and we don’t pretend every decision can be automated.

Four simple principles.

They are how we choose what to build and how to bring it into the firm.

  1. 01

    We start from the real work.

    Before automating anything we map the firm’s workflow: who does what, which data is needed and where professional judgement comes in.

  2. 02

    The accounting software stays.

    Prisma works outside the accounting software. Clerk works inside the one the firm already uses. We don’t ask anyone to start from scratch.

  3. 03

    AI doesn’t hide its doubts.

    When data is missing or a decision can’t be automated, the case is set aside and brought to the professional with the useful context.

  4. 04

    Every automation is earned.

    We start supervised and take on more only on the steps the firm has checked and approved.

We start from a real workflow, no abstract presentations.
