AVOID "AGGREGATED" processor like STRIPE. This company is a potential loss for merchants on disputed transactions. Why? simple. The first thing you need to know STRIPE is an AGREGATTED processor, this means they will not represent your case on your behalf. They will just forward the documentation you provide for the case and then block any other revision, this means if the bank needs additional information to give the chance for you to win the case providing additional documentation or anything in between, STRIPE will block this chance. I hade less than 0.5% disputes in my account. I had recently a case for $430, the customer filed a dispute for the full amount while being partially refunded 3 weeks previous to the dispute date, however, stripe alow to file the dispute for the full amount having records of the previous refund because it is the processor, "FIRST FAIL" not other processor fails on doing this. second, the order was delivered and documented by the customer, however, I lost the case INCLUDING THE PARCIAL REFUND, it means the customer was refunded in excess over the original transaction amount and of course in posession of the merhcandise. STRIPE caused me a loss over $900 allowing a refund over the original transaction amount plus STRIPE fees ( of course a deal). Do not mention that your store policy doesn't count at all when processing with stripe. In other words, even if you follow strictly the good rules as a merchant doing incredibly good to win a case, you will lose it using STRIPE. Period. They will not prove how they process your claim or "if they forward to the bank" ( on time, correctly, etc) your documentation, It is a blain process. The fact the partial refund was not recognized makes me think they never send my case to the bank otherwise the bank cannot refund a transaction over the original amount. I had less than 0.5% of disputes on this account, all of them lost with the same response: Bank did not provide details about why the case was lost" really?". having a dispute using STRIPE equals to money lost straight forward. Document yourself about the type of processor stripe it is and make your own decision. Every single order processed with STRIPE equals to stress if it could become a dispute. Doesn't matter they offer acceptable rates if you lose money on the other hand. Merchanst need to reduce risks of money loss. This processor is a RISK
