Point of sale module to receipts book, no invoices

Hello

I did not get any reply, perhaps i need to give more details because laws and accounting terms are different in each countries.

In Belgium in retail business when selling to private individuals customers, when it has no necessity to provide an invoice, we register all transactions to a receipt book, this one is in use for bakeries, butchers, general food stores, taverns ans many other small stores … and we make the total for the month days by days.

Without the possibility to disable invoicing, the point of sale module is unusable for a large panel of small stores.

In my case i am a TV and computer repair shop, i am selling small items and executing services mainly to private individual customers.

Thank you for your help.
