Creating a global sales invoice BE & NL

I sell via Bol.com and am paid every two weeks with a summary of sales. I created a sales invoice in Dexxter for each sale, which is quite time-consuming. Now I have heard that it is also possible to create a global invoice for Belgium & the Netherlands. What I mean is, after each payment

1 invoice

BELGIAN CUSTOMERS – BE

With the item x the amount of items sold

DUTCH CUSTOMERS – NL

With the item x the amount of items sold

I am not subject to VAT.

Is this allowed by law, or do I really have to continue to issue separate invoices?

My income is correct this way, and it is broken down separately per country.

And my inventory of items is neatly stated on the invoices and is therefore also kept track of in a good manner.

Thanks in advance.
