MBI HT - TTC Calculator

📋 Module Overview

MBI HT TTC puts a net/gross price calculator one click away in the Dolibarr top bar, so you can convert a price without ever leaving the page you are working on.

The module adds a calculator icon to the top bar, visible on every page and to every logged-in user. One click opens a panel that converts both ways between net and gross prices, using the VAT rates actually active for your company's country.

🎯 Benefits

• Convert a net or gross price without interrupting the entry you are in the middle of.
• Available from any page of the ERP, in a single click.
• The VAT rates offered are those of your own country: no manual entry, no risk of using the wrong rate.
• Opens straight from the keyboard for quick entries, without reaching for the mouse.
• The panel picks up the colours of the active theme: no visual break with the rest of Dolibarr.

⚙️ Features

• Calculator icon in the top bar, present on every page and for every logged-in user.
• Instant two-way conversion: type a net price and the gross price is computed, and the other way round.
• VAT selector filled with the active rates of your company's country, sorted by ascending value.
• Choice of the VAT rate preselected when the panel opens.
• Four-operation calculator with a keypad, supporting parentheses and negative numbers.
• Two buttons to send the calculated result to the net field or to the gross field.
• Automatic opening of the panel as soon as a digit is typed outside an input field, which can be enabled or disabled.
• Choice of the field focused when the panel opens: the net price or the calculator.
• Amounts accept both comma and period as decimal separator, as well as spaces for thousands.
• Rounding to the cent on every conversion, with a strictly reversible net to gross round trip.
• An incomplete expression is flagged visually instead of displaying a wrong result.
• Multi-company ready: VAT rates are filtered according to the current entity.
• The module creates no table and stores no data: it only reads the VAT rate table.

✅ Compatibility

• Dolibarr: 18 to 23
• Module designed to blend into the standard Dolibarr interface, whose active theme colours it reuses.
• PHP 7.4 or higher (depending on the Dolibarr version in use)
