    Faster carrier payouts, stronger capacity

    We run a mid-size logistics company, and our biggest headache was paying independent freight carriers scattered across a dozen countries. Every payout meant currency conversion fees, multi day delays, and carriers threatening to drop us for slower paying brokers. Since switching a chunk of our payouts to 0xProcessing, carriers get paid within the hour instead of within the week, and the automatic conversion means our finance team locks in costs without babysitting exchange rates. It's made us the broker carriers actually want to work with, which in an industry where capacity is everything, has quietly become one of our biggest competitive advantages.

    Competitors: BitPay, CoinPayments, CoinGate
    Pros:    Automatic conversion locks in costs without manual exchange rate monitoring
    Cons:    Requires carriers willing to accept crypto payouts

    Easy to fit into our existing process

    We were looking for a way to accept crypto payments with no changes to the rest of our workflow. After reviewing payment gateways, 0xProcessing was deemed more feasible than others. The setup was simple and once it ran, never required day-to-day attention. The ability to create payment requests is hassle-free and clear for daily transaction uses; hence, there is no confusion.

    Competitors: CoinGate, RIZON
    Pros:    Quick to get started|Supports multiple cryptocurrencies|Simple payment request|Clear transaction status
    Cons:    More detailed reporting would be useful|Dashboard customization is limited

    The goal is to move BitPay in order to utilize it globally.

    Following numerous payment drops and unexpected compliance holds with BitPay, we switched our primary checkout flow to 0xProcessing. Our global clients rely on cross-border technology, services, and products. We needed a payment gateway that is used to handling payment processing and won’t raise flags about something this usual. Actually the onboarding as merchant was quite easy. The API integration into Vettrack’s custom billing stack has taken the dev team the best part of about two afternoons and the docs don’t leave much to the imagination.

    To run its day-to-day operations, Stable is used. We rely heavily on this payment links feature, which is completely automated. The VRCS feature converts incoming volatile assets to stablecoins automatically. The latter aspect alone has given adequate protection to our margins during the dips which get tied up in the afternoon. The 18 supported networks includes nearly everything our clients use. The processing time in so minimal, and we have still yet to have our first chargeback or false fraud flag since we started using it. The interface is effective but has glitches.

    Competitors: BitPay, CoinGate, RIZON, Coinbase
    Pros:    Vrcs effectively mitigates market volatility risk|Supports a wide range of native tokens and|Transparent fee structure with no hidden billing surprises
    Cons:    Ui dashboard feels overly basic for complex financial analysis|No native fiat payout options available
