Yes, your invoices will automatically be number sequentially.

In many countries, it's legally required for Invoice numbers to be assigned sequentially, meaning that the number of each new invoice increases.  Therefore, it is not a good idea to simply number invoices '1', '2', '3', etc. as this can be confusing when invoice numbers reach double or triple figures.

Sequential Numbering

Solna’s integration with Stripe allows your customers to pay you directly from the invoice via the web invoice portal that’s generated every time you send and invoice. Your customers will receive an email with a link to the web portal, where they can make payments (powered by Stripe).

You will need to have synced your Stripe and Solna account beforehand to enable this functionality.
