Partners who never buy from you.

Yes, that is explicitly provided for. You create partners in the administration yourself, optionally partner and customer account in one go. A sales rep, a workshop or a planning office needs no customer account in the usual sense, only one through which the settlement runs.

Through the commission type absolute per order. Instead of a percentage the partner gets a fixed euro amount, independent of the goods value. There is also absolute per item, if the quantity rather than the order should count.

By switching off follow-up orders. Then commission only arises on the first order of a referred customer. Together with an absolute amount that makes a clear rule: a fixed amount per customer won, no matter how often and for how much they order afterwards.

Yes, through the Active switch. It stops new commissions but leaves entries, payouts and the assignment of the referred customers untouched. When a rep changes territory or a collaboration pauses, that is the right route, not deleting.

Yes, positive as well as negative. Every entry comes with a private note that only you see and a comment the partner reads in their account. That covers the special cases no automation knows: a bonus, a reversal after a partial return, an arrangement made outside the usual.

There are check columns for that. They show per order with a tick or a cross whether minimum age, customer group and order status fit. Through the context menu you open the calculation log, and the Commissions tab on the order names the reason when a commission is missing. So you do not have to guess.

No. They only see their referred customers anonymised, with a first name, an initial and a town. How many orders and customers are visible at all, whether there are extended statistics with a CSV export and whether the receipt may be downloaded is up to you.
