Hi Harm,
Sorry for the long delay. Actually, I think we might have understood your question in a way more complex than necessary.
So, answering your question again, yes. It’s possible to limit the amount of orders a logged user can make. This would be a possible setup:
– Set “General > Mode” as “Product orders”.
– Set “Date range” as “Lifetime”.
– Enable “Limits > Per product tag”.
– Set all your products with the same tag and take note of the tag id. Let’s say the tag ID is 99.
– Enable “Formula > Limits by formula”.
– Set your formula as:
[alg_wc_mppu term_id="99" limit="1"]
– Run “Tools > Delete & recalculate sales data”.
