Most of the stores we take on are a few years in. They sell something people reorder, they have moved past the point where a hosted checkout from their store platform was enough, and they have started to feel the costs that come with volume: a dispute ratio that someone now watches, fraud that a plugin catches after the charge rather than before it, renewals that fail quietly, and an upsell that would work if it did not require a second checkout.
We are a payment platform in the payment-facilitator model. Each business on it is the merchant for its own sales, is reviewed and approved on its own, and is paid out to a bank account in its own name. We hold the card data, run the screening, file the dispute responses and provide the dashboard; the acquiring banks and payment processors behind us settle the funds. That arrangement is why review takes a few days and why we ask for documents once, up front, rather than after the first chargeback.
It is not a fit for everyone. We do not open personal accounts, we do not process for a business other than the one that signed, and the acceptable use policy is enforced during review rather than after the fact. If that describes a store you run, the application takes about five minutes.
