Create and finalize invoices
Build an invoice from your customers and products, with quantities, units, discounts and VAT worked out as you type, and keep it as a draft for as long as you like. Finalizing it gives it the next official invoice number, takes the goods out of stock, records the sale in the books and locks it against editing. Two people finalizing at the same moment never get the same number. An invoice can be written in any of ten languages, whatever language you use the app in.
