Corrispettivi is the income earned by artisans and retailers, for which there is no obligation to issue an invoice unless expressly requested by the customer. If you are a professional, you cannot use receipts but must always issue an invoice.
Therefore, if you carry out a commercial activity, have a traditional shop or an e-commerce shop, you must fill in a special register, called the register of receipts where you enter the details (the total sum) of your sales on a daily basis.
There are two ways of keeping receipts: paper or local and electronic.
The analogue solution should only be used by those engaged in e-commerce.
If you have an e-commerce business, therefore, you will have to have a register, which can be paper-based (which you can still buy in stationery shops), an excel sheet or even other tools or software on the market.
The compilation of receipts consists of recording the total receipts for each day. Their transcription will then make it possible to determine the turnover and consequently also the income valid for the calculation of taxes and contributions.
If you have an e-commerce business and you compile receipts, you do NOT have to have a cash register and issue commercial documents or receipts, you only need to note down the daily sales total in your register.
For each sale, therefore, no tax document has to be entered in the package.
Let us now turn to telematic receipts. Those who are obliged to manage their receipts telematically are those who carry out craft or retail activities other than e-commerce.
If you have a traditional shop or are a small artisan, you will therefore have to manage your receipts telematically by equipping yourself with a cash register or similar solution. This management will imply for you the creation of a document that is issued to the customer for each daily transaction: the receipt or as it is called today a commercial document.
This document is issued with a special cash register, called telematics, which telematically sends the collection data to the Internal Revenue Service at the end of the day.
For the special setting of the telematic cash register you will have to contact a local technician who will give you all the information about its operation and the automatic sending of the daily data to the revenue agency.
If you only do a few transactions per day, because you are a small artisan for example and do not want to have a telematic cash register, you can send your receipts directly via the invoices and receipts area of the revenue agency. This is a more cumbersome operation, since for each sale or service you will have to log on to the revenue agency website each time and manually enter all the data required to issue the document.
Alternatively, you can always consider issuing an invoice for each customer.
Remember that issuing the commercial document is an alternative to issuing an invoice.
When you issue an invoice, the corrispettivo does not have to be recorded. Otherwise you will be declaring the same amount as if you had received it twice and will therefore be paying tax twice on the same amount. Be careful!
