Dear clients,
we would like to remind you that with the start of the new year, it is usually necessary to set up new numbering sequences for each billing group. In other words, for every billing group you need to enter a new starting invoice number for 2026 so that the numbering process runs correctly and smoothly from the beginning of the year.
Therefore, please check your numbering sequence settings in advance and, if needed, update them before issuing the first invoices in the new year. We recommend verifying the settings for all billing groups you use.
You can find instructions on how to do this in the ISPadmin system on our WIKI: Invoice numbering.
We wish you a successful start to 2026, with plenty of health, peace of mind, and energy for all your plans ahead.
