The number of invoices is not one after the other

Hi @emanuelemn,

Could you please check if you have selected Order Number under WooCommerce?> PDF?Invoices?> Documents?> Invoice?> Display?invoice?number? If so, please select Invoice number instead.

Since in most countries there’s a hard requirement for invoice numbers to be sequential without any gaps, to use the invoice numbers in the sequence (keep them separated) is crucial to comply to it. If you use the order number as invoice number there may be gaps, since the orders are numbered by the main WordPress post numbering system used by posts, pages, images, orders, coupons, products, etc.

For instance, if you create a new product, and upload an image for that product as well, between two orders placed, the order numbers will not be sequential (if the first order was #100, the product would be #101, the image #102 and the next order #103).

See Invoice numbers explained.

Hope it makes sense!

Thanks,

The module settings sound like you said above and skipped a few numbers.
