Three crypto checkout providers dominate the conversation when a merchant decides to accept stablecoins: Coinbase Commerce, BitPay, and Crossmint. They look superficially alike (a button, a hosted page, a webhook) but they target different buyers, settle in different currencies, and price transactions on different scales. This comparison ranks them on the eight dimensions a payments lead actually negotiates: fee, supported coins, supported chains, settlement, payout speed, ecommerce integrations, API quality, and KYC.
​

Coinbase Commerce is the cheapest pure stablecoin processor at 1% flat (Coinbase docs), BitPay runs 1–2% plus $0.25 with bank-fiat settlement (BitPay pricing), and Crossmint quotes credit-card on-ramp pricing alongside crypto on a per-plan basis (Crossmint pricing). Pick by destination, not by brand familiarity.

Per the Coinbase Commerce help docs, the product charges 1% per transaction with no monthly fee or setup cost, and pushes merchants toward USDC on Base where settlement clears in roughly two seconds at sub-cent network cost. The product sits inside a Coinbase Business account, so KYC is whatever Coinbase already requires for the parent entity.
​

The product moved decisively in 2026. Coinbase rebuilt Commerce around its Commerce Payments Protocol on Base, partnered with Shopify and Stripe to bring USDC checkout to the Shopify ecosystem natively, and announced a broader Coinbase Payments stack aimed at large ecommerce platforms. Merchants must export historical transaction data from the legacy Commerce dashboard before the protocol cutover; current docs at help.coinbase.com reflect the new flow.
​

Where it fits: a SaaS company billing $40,000 invoices to enterprise clients in USDC, or a B2B services firm whose customers already hold treasury USDC, will pay 1% and get the funds in seconds. A coffee shop processing 200 sub-$10 tickets a day will not, because no per-transaction floor exists, but the operational lift of running a hosted checkout for low-ticket retail is rarely worth it versus a card processor.
​

The published BitPay pricing page lists volume-tiered fees: 2% + $0.25 under $500,000 per month, 1.5% + $0.25 between $500,000 and $999,999, and 1% + $0.25 above $1 million. Settlement defaults to local fiat currency (USD, EUR, GBP, CAD, AUD) deposited to a bank account in 1–2 business days, with the option to settle in stablecoin or split the two.
​

BitPay supports the widest cryptocurrency catalog of the three. The processor accepts Bitcoin, Bitcoin Cash, Ethereum, Litecoin, Dogecoin, XRP, plus stablecoins including USDC, GUSD, and DAI, and adds new assets selectively. The plugin library is also the deepest: Shopify, WooCommerce, Magento, BigCommerce, WHMCS, and a QuickBooks integration for invoicing.
​

KYC is the friction. Merchant onboarding requires government-issued ID, business documentation, and bank verification, with approval typically running 1–7 business days and longer for high-risk industries. That same gate is the reason BitPay can deliver fiat to a US bank account, so merchants who care about clean GAAP accounting and predictable cash flow tend to accept the trade.
​

Crossmint occupies a different slice of the market. It started as an NFT credit-card checkout (buyer enters a Visa or Mastercard, Crossmint mints the NFT to the buyer's wallet or creates one on the fly) and expanded into a broader payment and wallet orchestration platform. Per the official crossmint.com/pricing page, fees are calculated per transaction and depend on subscription plan, volume commitment, card type, geography, currency, and blockchain.
​

Where Crossmint differentiates: credit and debit cards work alongside crypto, Apple Pay and Google Pay are built in, the platform supports buyers in 197 countries, and it spans 50+ blockchains for orchestration. Wallets are free up to 1,000 monthly active wallets and $0.05 per MAU after that, with tokenization actions starting at $0.01 per the same pricing page.
​

This shape fits NFT marketplaces, ticketing platforms, in-game item shops, and any product where the buyer might not own a wallet yet. It is less natural for a B2B invoice tool, where the buyer is sophisticated and the seller cares about a single fee line.
​

For a recurring $20 stablecoin charge, Coinbase Commerce wins on raw fee per Coinbase docs: 1% equals $0.20, with no fixed component. BitPay's $0.25 floor (bitpay.com/pricing) means a $20 transaction costs at least $0.45 (2.25%) at the entry tier. Crossmint pricing is custom per crossmint.com/pricing, but headless crypto checkout typically lands between Coinbase Commerce and a card processor depending on volume.
​

The recurring constraint changes the answer. None of the three offers true subscription billing the way Stripe does. Merchants on Coinbase Commerce stitch recurring charges through the Commerce API plus their own scheduler. BitPay supports invoice automation but each invoice is a fresh approval. Crossmint supports recurring through its checkout SDK on supported chains. If recurring billing is the primary requirement, a stablecoin payment processor with native subscription primitives will outperform all three.
​

Coinbase Commerce setup is the lightest. Open a Coinbase Business account, complete merchant verification, generate API keys in the Commerce dashboard, and either install the Shopify or WooCommerce plugin or POST a charge to api.commerce.coinbase.com. A merchant who already has Coinbase Business KYC can be live in under an hour.
​

BitPay setup takes 1–7 days. Apply for a merchant account at bitpay.com/merchant-signup, submit KYC documents, link a bank account for fiat settlement, then install the platform plugin or integrate the BitPay Invoice API. Settlement currency, daily payout threshold, and fee tier are configured before going live.
​

Crossmint setup runs through a console at staging.crossmint.com (test) and www.crossmint.com (production). Create a project, configure supported chains and currencies, drop in the Pay Button or call the headless checkout API, and configure webhooks for order events. NFT-checkout flows additionally require a contract address.
​

For high-ticket B2B (large invoice values, treasury-grade counterparties, USDC preferred), Coinbase Commerce is the default per Coinbase's documentation. The 1% fee is the lowest published rate among the three, settlement on Base is fast enough that finance teams stop asking questions, and the brand satisfies risk committees that already know Coinbase as a custodian.
​

For crypto-native consumer brands and merchants who need fiat on the other side, BitPay is the answer. A merchant accepting payments from holders of BTC, LTC, or DOGE, who needs USD or EUR in a bank account by Friday, gets that with one provider and one reconciliation file. The fiat-conversion guarantee is the product.
​

For NFTs, in-app purchases, ticketing, and any flow where the buyer pays by card and the seller settles onchain, Crossmint is the only one of the three built for that pattern. Its stablecoin-orchestration product also picks up cross-chain settlement work that the other two do not target.
​

Beyond the three, two other categories matter for stablecoin checkout. Card-rail processors with stablecoin acceptance (notably Stripe, which lets merchants accept USDC and settle in fiat through the standard Stripe payout) make sense for merchants already on Stripe; see the how to accept stablecoins on Stripe writeup for the exact flow. Platform-native plugins such as the Shopify USDC integration covered in how to accept stablecoins on Shopify often beat third-party gateways on fee.
​

Pure onchain processors (NOWPayments, Paymento, Aurpay) compete with Coinbase Commerce on price but lag on enterprise trust signals. B2B-specific tools (Request, Otto, Bitwave for accounting) target invoice flows; the comparison in best B2B stablecoin invoicing tools 2026 covers that bracket directly. Effective fees vary widely; the breakdown in stablecoin payment processor fees compared 2026 normalizes them on a single basis.

Pricing and feature claims pulled from the official Coinbase Commerce, BitPay, and Crossmint documentation in May 2026. Stablecoin supply context (USDC at $78.1B, USDT at $189.5B, DAI at $4.6B, PYUSD at $3.4B) sourced from DeFiLlama as of May 4, 2026. Where official documentation does not publish a number (Crossmint's per-transaction rate is plan-dependent), the comparison says so rather than estimates.
