no , i mean something like updated information on current transaction like for example buyer buy an account with which payment, playerup could email us something like invoice that telling a buyer has made a payment with [abc payment gateway]. then later when seller input the payment form, it should have something like confirmation again about the form has been added and the payment with total $xxx will be send to abc address in 24-72 hours (just an example) so even without middleman getting online, seller will know about how much the total money they will get and can expect when to get their money.
Thank you for your suggestion. What you're asking is a more advanced backend ordering system like amazon for example when a buyer pays it notifies the seller to deliver and the seller knows what they bought and how much and it can all be tracked in the backend and like many other sites. While Middleman 2.0 hasn't been launched yet we are working on both Middleman 2.0 (V2) and Middleman 3.0 (V3) at the same time. Middleman 3.0 will have what you're asking for. In short here, when we do launch Middleman 3.0 you will have the option to choose from the old or new system (though we are still discussing merging them but others have said they like the old system). It will be the exact same process and you won't need to do any additional work just that you'll select the new version versus the old version (won't be complicated). The only requirement with the new version (Middleman 3.0) is you'll have to be registered to PlayerUp before you can use the middleman feature whereas with the old or current version you aren't required to be a member.
No specific ETA right now. MM 2.0 is a completely different system being built offsite which will boost seller sales but doesn't impact buyers on playerup. This system is almost done. MM 3.0 is partially built but has a ways to go as we have taken "breaks" on development so we can make sure the system is built right and we had time to think about it. Ultimately we will have 2 different unique systems on PlayerUp one being more customized and one being more system automated oriented like @BonBin wants above.
