How we work

We build software that removes unnecessary work from accounting firms.

Mastro develops software for Italian accounting firms. We start from real flows, work with the tools that the firm already uses and leave the decisions that require judgment to the accountant.

What we do

We connect documents, communications, deadlines and accounting work to reduce manual steps and double-checks.

What we don't do

We don't promise a firm without people, we don't replace management and we don't pretend that every decision can be automated.

Four simple principles.

They are the criteria by which we choose what to build and how to introduce it into the firm.

We start with real work.

Before automating, let's reconstruct the flow of the firm: who does what, what data is needed and where professional judgment comes into play.

Keep the accounting software you already use.

Mastro works outside the accounting software. Clerk works within what the firm already uses. We are not asking to start from scratch.

AI does not hide uncertainty.

When data is missing or a decision cannot be automated, the case is separated and brought to the accountant with useful context.

Every automation is earned.

We start with supervision and increase responsibility only on the steps that the firm has verified and approved.

Let's start from a real flow, without abstract presentations.

What it costs

The bill is one number: seats times the plan price. Clients are already included.

Clients included in the plan, for the whole firm

The hundred-client pack is one line for the firm, the same on every plan, and it does not change with the number of seats. No seat minimum, no annual lock-in.
