Using Multiple Invoice Sequences

Currently, Quaderno does not support multiple invoicing sequences through a dedicated feature.

Why only one invoice sequence?

Tax legislation requires that all invoices issued by a single tax entity maintain a continuous numerical sequence (with no gaps or duplicates).

The primary value of Quaderno is the automated issuance of invoices via our integrations. However, we cannot manage different sequences automatically because the data we receive from integrations often lacks the necessary information to unequivocally determine which sequence a specific invoice belongs to.

Recommendation for Invoice Classification

If you need to classify your invoices by activity type, department, or any other category, we strongly recommend using tags. This is the most effective way to organize and filter your invoicing without compromising the legal requirement for a single numerical sequence.
