Invoice Numbering in Sales
Dealersip provides flexibility to manage invoice numbering while ensuring compliance with common accounting and legal practices.
You can start your own invoice number sequence. When adding a sales entry, if the Invoice Number field is left blank, Dealersip will automatically assign the next sequential invoice number. If you manually enter an invoice number, Dealersip will accept it only if the number is unique within the dealership and within the selected invoice prefix.
An invoice number is considered unique based on two conditions:
- It must be unique within the same dealership
- It must be unique within the selected invoice number prefix
Once a sales entry is saved, the invoice number cannot be modified. This restriction is intentional to maintain accounting integrity.
If a sales entry is deleted from the list, Dealersip does not auto-renumber existing invoices. It also does not automatically reuse or consume the skipped invoice number. This ensures that invoice numbers remain consistent and traceable.
You can modify the invoice prefix at any time. The prefix plays an important role in managing different invoice sequences.
Starting a New Invoice Number Sequence
If you want to start a new invoice number sequence, for example at the beginning of a new financial year, you must change the invoice number prefix. Dealersip does not automatically restart invoice numbers because, in most countries, accounting laws do not allow skipping or reusing invoice numbers.
To start a new sequence:
- Change the invoice number prefix to a new value (for example, based on the new financial year)
- Enter any starting invoice number for the first sale under the new prefix
- For subsequent sales, leave the invoice number field blank
Once the first invoice is saved under the new prefix, Dealersip will automatically generate the next invoice numbers sequentially.
