Hello Rik,
I hope you are well today.
It is possible to limit one order per customer for one week with our Maximum Products per User for WooCommerce. To do so, please follow the general instruction below:
1. At first, assign all of your products to a particular tag,
2. Then please navigate to WooCommerce > Settings > Maximum Products per User > General and set Mode to Product orders
. Then set the Date range to This week
and Order statuses to appropriate statuses
,
3. Next, navigate to Products > Tags > Your tag > Edit and set the Limit per user to 1
.
Please give it a try. If you have any other questions, then please let us know.
Kind regards,
Moshtafizur
