Customers credit card keeps declining on invoice payment. She has tried multiple cards

[AmuseBouch]

My customer is trying to process a payment for $8k to satisfy an invoice. None of her cards are working and she even tried her sisters credit card. They have called their banks and all stated that the decline was on my end not the banks. What can I do to resolve this?

@AmuseBouch There could be a number of reasons, but are they trying to pay it online?  do you have the ability to physically dip or tap the card?

Is your account new?  that is a very large payment and it is one that is ripe for chargeback or just straight fraud.  I think that might be the reason, if you don't regularly process or have a long history it may be setting off red flags internally..

That is just my experience and is anecdotal at best.

I’ve been using square for my business since 2015 and have processed larger payments before. This client is a repeat client and has used the same cards in the past with the exception of trying her sisters with permission. I think the error had something to do with the invoice itself, I’m an event planner and decorator and the invoice was modified multiple times AFTer the first and 2nd payments so I believe something about editing to many times is what the system doesn’t like. I made a new invoice for the remaining balance and the same card that kept declining the same amount worked on the new invoice which further supports my theory. I wish square offered real time customer support because expecting us to crowd source support is ridiculously inefficient and irresponsible for a financial institution. But I digress thanks for trying to answer to the best of your knowledge
