Choosing the right crypto payment processor can make or break an online business that accepts digital currencies. With dozens of options on the market, merchants need a clear picture of what each platform offers before committing. This guide compares three popular solutions — NOWPayments, CoinGate, and BTCPay Server — to help you pick the best fit for your store.
Whether you’re running a small e-commerce shop or a large-scale SaaS platform, understanding the differences in fees, supported coins, customization, and control is essential. Below, we break down each processor, compare their strengths and weaknesses, and provide actionable guidance for making your decision.
NOWPayments
NOWPayments positions itself as a non-custodial crypto payment gateway, meaning funds never touch your merchant account — they go straight from the buyer to your wallet. The platform supports over 100 cryptocurrencies and stablecoins, includes a built-in multi-wallet system, and offers both fixed and floating rate conversion. Merchants can accept payments via checkout widgets, payment buttons, APIs, or plugins for major CMS platforms like WordPress, WooCommerce, Shopify, and Magento.
One of the standout features is the ability to auto-convert incoming payments into any supported coin, which helps merchants avoid volatility risk without managing multiple wallets manually. The platform also supports staking rewards on certain assets through its native NPS token ecosystem.
Fees and Payouts
NOWPayments charges a flat 0.5% fee per transaction across all payment methods, including the Fixed Rate Plus and Floating Rate options. There are no monthly fees, setup costs, or hidden charges. Minimum fees vary by payout coin but typically start around $1 equivalent. Settlements are instant when sending directly to external wallets.
Key Features
- Support for 100+ cryptocurrencies and stablecoins
- Auto-conversion between assets
- Non-custodial architecture
- Built-in donation pages and subscription billing
- Merchant API and webhooks for custom integrations
- Free plugin ecosystem for popular platforms
CoinGate
CoinGate is a established crypto payment processor founded in 2014, based in Europe. It supports more than 70 cryptocurrencies and offers a range of products including a payment gateway, light terminal for in-person sales, invoice creation, and a marketplace widget. CoinGate also provides a fiat settlement option, allowing merchants to receive payouts in traditional currencies like EUR, USD, or GBP.
The platform integrates with WooCommerce, Shopify, PrestaShop, OpenCart, Magento, and other e-commerce systems. Its API is RESTful and well-documented, suitable for developers building custom checkout flows. CoinGate also runs its own Bitcoin Lightning Network node and supports LN payments natively.
Fees and Payouts
CoinGate’s standard merchant fee is 0.9% for crypto settlements and 1.5% for fiat settlements. For high-volume businesses processing over €1 million annually, custom pricing is available. The platform applies a minimum fee of €0.01 per transaction. Withdrawals to external wallets are free, while payouts to bank accounts may incur additional charges depending on the provider.
Key Features
- 70+ supported cryptocurrencies
- Fiat settlement in major currencies
- Lightning Network support
- In-person light terminal
- Invoice and payment link generation
- Chargeback protection on select products
- Multi-user access with role-based permissions
BTCPay Server
BTCPay Server is a self-hosted, open-source Bitcoin and cryptocurrency payment processor. Unlike CoinGate and NOWPayments, it requires you to run your own server instance, giving you complete control over funds, data, and configuration. There are zero transaction fees because BTCPay Server connects directly to your blockchain nodes — no middleman takes a cut. The software supports Bitcoin, Lightning Network, Litecoin, Dogecoin, Zcash, and many other coins and altcoins.
Because it’s fully self-custodial, BTCPay Server appeals to privacy-focused merchants and organizations that prioritize financial sovereignty. However, this comes with technical overhead: you need to manage server infrastructure, keep your nodes synced, handle security hardening, and perform updates yourself. A hosted version called StacksBit exists but still mirrors the same self-hosted philosophy.
Fees and Payouts
0% transaction fees. You only pay the underlying blockchain network fees (miner fees and Lightning routing fees). There are no platform markups, no monthly subscriptions, and no withdrawal charges. This makes BTCPay Server the most cost-effective option for high-volume merchants.
Key Features
- Fully open-source and self-hosted
- Zero transaction fees
- Direct integration with your own full nodes
- Lightning Network support with multiple LND implementations
- Multi-currency support beyond Bitcoin
- Built-in point-of-sale system
- Multi-signature wallet support
- Plugins and themes community-driven

Which Processor Should You Choose?
The right choice depends on your priorities. If you want the lowest fees and don’t mind managing infrastructure, BTCPay Server is unbeatable. Running your own payment processor eliminates intermediary costs entirely and gives you total control over how transactions flow. The tradeoff is technical complexity — you’ll need DevOps knowledge or someone who can maintain your servers and node infrastructure.
If you prefer a managed solution with minimal setup effort, NOWPayments offers the simplest onboarding experience. Its 0.5% flat fee is competitive, the 100+ coin support covers virtually every asset buyers might use, and the auto-conversion feature removes the headache of holding volatile balances. It’s ideal for small to mid-sized stores that want crypto acceptance up and running in minutes.
CoinGate sits between these two extremes. It’s a fully managed service like NOWPayments but adds fiat settlement capabilities that matter if you want to convert crypto revenue into traditional currency automatically. The slightly higher fee structure reflects this added convenience. CoinGate is also a solid choice for merchants who already process significant fiat volume and want a single vendor handling both streams.
Decision Checklist
Consider NOWPayments if:
– You want the fastest setup with zero technical overhead
– You need broad altcoin support beyond Bitcoin and Ethereum
– You want automatic coin conversion to manage volatility
– Your transaction volume is moderate and the 0.5% fee is acceptable
Consider CoinGate if:
– You need fiat payout options alongside crypto acceptance
– You operate in-person retail locations (Light terminal)
– You value an established provider with European compliance infrastructure
– You want chargeback protection on select products
Consider BTCPay Server if:
– Minimizing fees is your top priority
– You have technical resources to manage servers and nodes
– Privacy and self-custody are non-negotiable
– You process enough volume that avoiding per-transaction fees matters significantly
All three platforms support the major e-commerce integrations and offer developer-friendly APIs. Test them with small transactions before committing — each behaves differently under real-world conditions, and what works perfectly in documentation might feel different during peak traffic periods.
