Invoice number - change or reset counter

Hi I need to change the invoice counter number in order to start from invoice 16 for example. How can i do it?

Waiting for your help and thank you very much for your reply

Hello

Go to Events Booking -> Configuration, set Invoice Start Number config option to 16 and it should work as expected

Note that this will only work if you don't have existing invoices in the system. If you have already invoices in the system, Invoice Start Number config option will have no effect

Ok The system have generated three invoices because i made a mistake registring some partecipant by myslef (they are not able to use computer!). No I want to cancel these invoices and take the invoice number back.
Where I can modify this? Should I cancel the invoices in the DB?
Please give me some help.
Thanks

I think you can try to cancel the invoice number through db. Look at your site database via phpmyadmin, find the table #__eb_registrants, change data of invoice_number column to have the number you want
