if i send order in negative value???

_paq.push(['trackEcommerceOrder',
'ID002',
'-33,95',
]);

this code add value in ecommerce analytics??

Also we want to handle:

• Subscriptions
• Churn
• Recurring revenue
• Forecast revenue
• etc.

Maybe also something to look into : #11562 carts across visits

After some long consideration I figured it may not be worth it implementing subscription support right now and instead created this issue #15361 . A workaround is available using events and it might be better to simply write a blog on how to do this. I'm writing a guide about this

@mattab I wonder how important tracking refunds (and cancellations) really are? Doesn't seem maybe too important? Eg not seeing many comments here or users asking for it. Also thinking we could introduce this feature later in a minor Matomo 4 update if needed since we mainly would need to introduce new idGoals like idGoal -2 === refund . Could move it back to priority backlog maybe?

Just wanted to chime in that I would appreciate refund support. My main use-case is appointment bookings. If an appointment is cancelled, it would be nice to track the "refund".

I also just want to say that these features would be very helpful for me!
More detailed Abandoned Cart and Refund Information in particular.

But this seems to be low priority since Ticket #9176 was closed and not followed up for almost half a decade :(

Also interested in cancellation feature since there are many eCommerce sites that in some cases can't validate payment upon order completion and orders have to be cancelled later (for example with direct bank transfer payments or paying in office during self pickup).

Refunds and cancellations are a common occurrence in eCommerce world and affect revenue calculations so it's important to allow tracking them in analytics tools.
