Choosing the right crypto payment gateway can make or break an online business. Processing fees, settlement times, supported currencies, and ease of integration all factor into the decision. This guide breaks down four major options — BitPay, Coinbase Commerce, Binance Pay, and Comet Payment — so merchants can pick the solution that fits their operation.
For businesses looking for a single platform that covers all of these providers alongside additional options, bitpay coinbase commerce binance pay comet offers a unified checkout experience across dozens of payment processors.
NOWPayments Overview
NOWPayments operates as an aggregator, giving merchants access to multiple payment processors through one API integration. Instead of managing separate accounts with BitPay, Coinbase, Binance, and others, a single integration routes transactions to the appropriate provider. The platform supports over 100 cryptocurrencies and offers both fixed and variable rate options. Standard fees start at 0.5% per transaction, with no monthly charges or minimum volume requirements. Settlement can go to a personal wallet, exchange, or NOWPayments’ own balance. The platform also provides plugins for WordPress, Shopify, WooCommerce, and other e-commerce systems.
Fee Structures Compared
Merchant fees are the most immediate differentiator between these payment gateways. Here is how each one stacks up on cost.
| Provider | Base Transaction Fee | Additional Charges | Payout Currency |
|---|---|---|---|
| BitPay | 1% | Withdrawal fees apply | USD, EUR, GBP |
| Coinbase Commerce | 0% platform fee | Network gas fees only | Crypto only |
| Binance Pay | 0% for Binance users | Small conversion spread if applicable | BNB, BUSD, USDT |
| Comet Payment | 0.5%– 1% depending on volume | None disclosed | Multi-crypto |
| NOWPayments | 0.5% | Optional withdrawal fees | Any supported crypto |
BitPay charges a flat 1% per transaction, which sits in the middle of the competitive landscape. Coinbase Commerce does not take a platform cut, making it the cheapest option on paper — but merchants still pay network gas fees and may face higher spreads when converting to fiat. Binance Pay runs at zero commission for transactions staying within its ecosystem, though currency conversions introduce implicit costs. Comet Payment positions itself with lower rates starting at 0.5%, scaling down with volume. NOWPayments sits at 0.5% base and adds flexibility by supporting multi-provider routing.
Hidden Costs to Consider
Beyond the headline percentage, several factors affect true processing costs. Currency conversion spreads can add 0.5% to 2% on top of stated fees. Chargeback protection varies significantly — BitPay offers seller protection on select transactions while Coinbase Commerce leaves dispute resolution entirely to the merchant. Minimum payout thresholds differ too; some platforms require $10 before initiating transfers while others allow instant withdrawals regardless of amount.
Supported Cryptocurrencies and Coverage
The range of accepted coins matters for reaching international customers who prefer specific tokens.
BitPay supports roughly 25 major cryptocurrencies including Bitcoin, Ethereum, Litecoin, Dogecoin, and stablecoins like USDT and USDC. It focuses on well-established assets rather than chasing every new token. This conservative approach reduces risk but limits appeal among audiences who favor altcoins.
Coinbase Commerce covers around 40 assets, including Bitcoin, Ethereum, Dai, USD Coin, and various Layer-2 tokens. Its connection to Coinbase Exchange means automatic conversion to major coins is straightforward. Merchants who want broad coverage without managing individual wallets benefit from this setup.
Binance Pay leverages the Binance ecosystem, supporting hundreds of tokens native to the exchange — including BNB, CAKE, SHIB, MATIC, and many more. If the target audience already trades on Binance, the friction drops dramatically since users can pay directly from their exchange balances.
Comet Payment supports 30+ cryptocurrencies with a focus on popular tokens and high-volume stablecoins. The selection prioritizes liquidity over sheer count.
NOWPayments goes further with support for 150+ cryptocurrencies, including niche tokens and DeFi assets that the other platforms do not handle.
Integration Complexity and Developer Experience
How quickly a merchant can go live affects cash flow during onboarding. Each platform takes a different approach.
BitPay requires KYC verification and manual account approval before accepting payments. The API documentation is thorough with SDKs for Python, Node.js, PHP, and Ruby. Checkout customization is possible through hosted pages or embedded widgets. Setup typically takes one to three business days due to compliance checks.
Coinbase Commerce offers the simplest technical integration. There is no mandatory KYC for basic usage — merchants generate API keys and receive webhook URLs immediately. The integration consists of creating a payment request object and redirecting customers. Customization options are limited compared to BitPay but sufficient for most use cases.
Binance Pay integrates through the Binance Payment API, which requires developer registration and sandbox testing. The documentation includes examples for multiple languages. Mobile SDKs exist for iOS and Android. Approval can take two to five business days depending on region.
Comet Payment provides REST APIs with webhook support and SDKs for common frameworks. Onboarding involves identity verification similar to BitPay. The dashboard offers real-time analytics and automated reconciliation reports.
NOWPayments abstracts the complexity further by offering a single API that routes to whichever processor the merchant configures. Plugins exist for every major e-commerce platform including Shopify, WooCommerce, Magento, PrestaShop, OpenCart, and BigCommerce. For custom builds, the API accepts standard POST requests with JSON payloads.
Settlement Options and Liquidity Management
How and when merchants receive funds impacts working capital and tax reporting.
BitPay settles in fiat currencies (USD, EUR, GBP) to linked bank accounts with next-day availability for verified merchants. Crypto settlements are available but incur additional withdrawal fees. Funds held in BitPay wallets earn no interest.
Coinbase Commerce settles exclusively in cryptocurrency. Merchants must independently manage conversion to fiat through external exchanges or custodial services. This approach puts full control in the merchant’s hands but requires active treasury management.
Binance Pay settles directly into Binance accounts, enabling instant trading, staking, or savings products within the Binance ecosystem. Users can auto-convert incoming payments to stablecoins or hold them as yield-bearing assets. This creates opportunities for passive income that other platforms do not offer natively.
Comet Payment allows settlement to personal wallets, exchange accounts, or direct fiat payouts where available in supported regions. Multi-currency holdings are possible within the platform dashboard.
NOWPayments provides maximum flexibility — merchants can route payouts to any external wallet address, send funds to exchange accounts, or keep balances within the platform. The fixed-rate feature locks in conversion prices for 15 minutes during checkout, protecting against volatility between order placement and payment confirmation.
Compliance and Regulatory Standing
Operating a payment gateway touches financial regulations that vary by jurisdiction.
BitPay holds Money Transmitter Licenses in multiple US states and complies with FinCEN regulations. It undergoes regular SOC 2 audits and maintains PCI DSS certification. European merchants benefit from PSD2 compliance. The heavy regulatory footprint means slower onboarding but stronger legal protections.
Coinbase Commerce inherits Coinbase’s regulatory infrastructure, including MSB registrations and state-level money transmitter licenses. The company publishes annual transparency reports and cooperates with law enforcement on suspicious activity investigations.
Binance Pay operates under Binance’s broader licensing framework, which includes MSB status in the US, VASP registration in the EU, and regional licenses in Asia. Regulatory scrutiny has increased globally, affecting all Binance-related services.
Comet Payment complies with anti-money laundering regulations in supported jurisdictions and conducts routine KYC checks on merchant accounts. Specific licensing details are less publicized than the larger competitors.
Which Gateway Fits Your Business
The best choice depends on operational priorities. Merchants who need fast fiat payouts with regulatory backing should consider BitPay. Those who want zero platform fees and handle their own treasury management may prefer Coinbase Commerce. Businesses already inside the Binance ecosystem get the most value from Binance Pay’s integrated features. Companies seeking the lowest base fees with multi-provider flexibility find Comet Payment and NOWPayments appealing.
Volume matters too. High-volume merchants often negotiate custom rates with any of these providers. Low-volume stores benefit most from platforms with no monthly fees and minimal minimums — Coinbase Commerce and NOWPayments lead here.
