Check Supported Features
Does it support Lightning Network? Fiat settlement? Subscription payments? Multi-currency? Mobile optimization?

Review Support & Reliability
What's the uptime guarantee? Is support available 24/7? What do user reviews say about their support quality?

⚠️ Common Mistakes to Avoid
- Focusing only on headline fees — hidden costs (settlement fees, conversion fees, network fees) can double your total cost.
- Choosing a gateway without testing — always run a test integration before committing to a gateway.
- Ignoring customer support quality — when payments fail, you need fast, competent support.
- Overlooking regulatory compliance — ensure the gateway is licensed in your jurisdiction if you need fiat settlement.
- Not considering future growth — choose a gateway that can scale with your business volume.
- Choosing a gateway that doesn't support your customers' preferred coins — if your customers use TRON/USDT, make sure your gateway supports TRC20.
