How to manage depreciation ?
Above a defined amount (250 € in Belgium), the professionnal expenses have to be depreciated in several years.

No need for complicated tables anymore, just input the number of years of depreciation inside the expense form and AMI will take care of all the calculations for the yearly deductions (visible in the taxes estimate and the accounting results).

The depreciation duration depends of the object and the usage you'll make of it.

In general most accountants use standard durations, such as :
- new vehicle : 5 years
- used vehicle : 3 years
- computer: 3 years
Managing cash book

All self-employed people are required to keep a cash book as part of their accounts


This book contains all the transactions carried out on your company's accounts.

Many self-employed people still record this in spreadsheets such as Excel, which can lead to numerous errors.
The good news is that AMI Project offers you automatic, centralized encoding!

Add transactions

Incoming (business expenses) and outgoing (sales invoices) transactions will be added automatically.
For others (payment of VAT statements, transfers between accounts, etc.), you can still add them manually.

Add a transaction

At the end of the year, export your summary for printing, or save it to attach to your tax return.

Recap treasury
Is it possible to remove a type of expense?

Your accounting must remain intact for 7 years.

It is therefore not possible to delete an expense type that is still in use, even if it is from previous years.

However, if you wish to delete an unused expense type, you can communicate this to us via e-mail or technical support.
