First off, you’ll want to consider how you want your invoice numbers to be structured. And how about your customer numbers? This may be specified under Settings > Documents > Number ranges. For each data type, it is possible for you to establish a prefix and minimum number length, which will then be supplemented with leading zeros where necessary. Let’s assume that your invoices will be using the format “RE-007” for invoice numbers. In this case, “RE” would be the prefix, which is the text component that Billomat will automatically add to the incremental number. The result would be “RE-7” as an invoice number. In order to have zeros inserted before the incremental number, all you have to do it select a length of 3 in the settings—turning the 7 into 007.
Please note that invoice numbers are assigned provisionally to start off with. As long as a document remains in draft mode, the invoice number is temporary. When you finalize the document, it will then receive its permanent number.
If you wrote invoices or administered customers before switching to Billomat, then you will probably not want to start counting with the number 1. No problem here, either. When you create your first data record , you can simply change the number there. Billomat will then automatically keep counting from this number on.
