• Fraud Prevention: Stripe offers built-in fraud detection and prevention tools, such as Radar, which uses machine learning to identify and block fraudulent transactions, helping businesses minimize chargebacks and financial losses.
• Subscription Management: For businesses with recurring revenue models, Stripe Billing provides a sophisticated system for managing subscriptions, invoicing, and dunning processes, automating much of the complexity associated with recurring payments.

The company positions itself as a partner focused on long-term value rather than short-term gains, emphasizing clarity in its fee structure.

Key Features:

• Interchange-Plus Pricing: Payment Depot operates on an interchange-plus pricing model. This means you pay the direct interchange rate set by the card networks (like Visa and Mastercard), plus a small, fixed markup from Payment Depot.

• Dedicated Support: Having a dedicated account manager ensures that businesses have a single point of contact for all their processing needs, fostering a stronger client relationship.

• Not Ideal for Low Volume: Businesses processing only a few thousand dollars per month might find the monthly fee outweighs the savings from interchange-plus pricing, potentially making other, simpler flat-rate solutions more economical.

Pricing:

Payment Depot offers a pricing structure that includes a monthly membership fee of $59. On top of this, transaction fees are set between $0.07 and $0.15 per transaction, in addition to the direct interchange rate. The first month of service is provided free of charge.

Payment Depot stands out for its commitment to transparent, wholesale-level pricing through a clear interchange-plus model and a predictable monthly membership fee.
