Read the guide (in Italian)

A wrong promissory note is more than a badly filled title.

It puts at stake its legal value, your work and the time it takes to fix, and it can lead to serious disputes. Twelve, twenty-four, thirty-six instalments: notes that are all the same except for the date. That is where mistakes happen.

You copy them out by hand, one by one.

Same name, same address, same bank, for every instalment. Time nobody pays you for.

One moment of distraction is enough.

Two digits swapped, an amount in words that does not match, a due date on the 31st of a 30-day month.

And the mistake is expensive.

Under Italian law, if figures and words disagree, the amount in words prevails. A badly filled note can also lose its force as an enforceable title: instead of going straight to enforcement, you have to go to court.

Word with macros, an Excel sheet, a typewriter: none of them knows what a promissory note looks like.

Effetto knows what a promissory note looks like. You type the details once.

    Fill in

    Debtor, bank, amount, first due date, number of instalments. One grid, like a form.

    File

    The plan stays on file: mark the paid and unpaid notes, and reprint it whenever you need.

What changes

Type once, print the whole plan.

Debtor and bank are entered once and apply to every instalment. Even 120 notes, even every other month or quarterly.

Figures and words always match.

Effetto writes the amount in words from the figure you entered: they cannot disagree. It works out the due dates too: if the first falls on the 31st, February's falls on the 28th.

It stops you before the form.

If the tax code does not add up, a bank code is missing a digit or the province does not exist, it tells you before printing, all at once.

Every plan, on file.

Each plan stays in the archive with its notes: mark the paid and the unpaid ones, and reprint without retyping anything.

Born in the field

Effetto is written for people who prepare repayment plans every day. The position of every detail on the form is checked against notes actually printed, to a tenth of a millimetre.

A Windows computer or a Mac, and the printer you already have.

Computer
Windows 11 or Windows 10, 32-bit included: there is a separate version for it. It does not run on Windows 7 or 8.
Mac
macOS 10.15 or later, with an Intel or Apple chip. Effetto is new on the Mac: the first time, make the test print on a blank sheet before using the forms.
Printer
Your current printer will do, even an A4-only one: a test print on a blank sheet shows you how to feed the form.
Installation
A few clicks, no administrator password. The first time, Windows may show “Windows protected your PC”: click “More info”, then “Run anyway”. On a Mac you drag Effetto into Applications, and the first time you open it from System Settings, Privacy & Security, “Open Anyway”.
Internet
Only to download it and for updates. Filling in, checking and printing work offline, and none of your data reaches us.
Updates
Effetto is currently at version 1.0.21, released on 9 October 2026. When a new version comes out Effetto tells you, and you decide when to install it. Archive and settings stay where they are.

You can use Effetto on your own. If you like, we guide you.

Optional paid professional services, delivered remotely by the person who wrote Effetto.
