Access is not released until both arrive — a purchase with one payment missing is not a purchase. Once the invoice's hour is up, the site emails you the amount that is missing and the address it goes to.
Send the missing amount, exactly, to that address — do not open a fresh purchase.
Going back to your existing purchase page is safe: it shows the payment that already arrived as a receipt rather than asking for it again. 🚨 Do not start the purchase again. The site will stop you — while this purchase is open, going back to the work brings you back here rather than to a fresh one — so the amounts on this page stay the only ones to pay. Paying the price a second time is something nothing in this system can reverse.
If you have in fact sent both, you need do nothing else — the case has already gone to BSVSearch for review.
If you would rather not finish it at all, Cancel this purchase is offered only while neither half has arrived. Once one payment is in it is no longer offered — that money has moved on the blockchain and nothing here can reverse it. Leaving the purchase unfinished costs you nothing further, and the case goes to BSVSearch for a decision.
