The book should be held to the daily and chronologically. If the sum of the receipts for sales or services to an individual is less than 76 euros, it can be consolidated and recorded at the end of the day. Regarding the terms of payment, it should be noted that the auto entrepreneur is not authorized to collect cash for an amount greater than 1000 euros.

The expense book

The register of expenses, or register of purchases, is an obligation only for entrepreneurs whose activity consists in selling goods, supplies, food to be consumed on the spot or to take away and to provide accommodation services . This second book must include, in the same way as for the recipe book, the following information:

Origin of purchases (name of supplier)

Amount of purchases

Method of payment (by check, transfer, cash)

Supporting references (invoice numbers, notes and tickets)
