Cryptocurrency payment processing is one of those areas where the fine print matters more than most merchants expect. A seemingly small percentage difference in transaction fees can add up quickly when you are running an online store, subscription service, or digital marketplace that handles dozens or hundreds of payments every day. Understanding how different platforms charge for their services helps you pick a solution that actually fits your business model instead of bleeding margins on hidden costs.
A crypto payment gateway sits between your store and the customer’s wallet, converting crypto into settlement currency if needed, handling blockchain confirmations, and depositing funds into your account. Every step along that chain carries a price tag, and those tags look very different from platform to platform.
How Payment Gateway Fees Actually Work
Before comparing specific providers, it helps to understand what makes up the total cost of accepting cryptocurrency. Most gateways layer multiple charges on top of each other.
| Fee Component | What It Covers | Typical Range |
|---|---|---|
| Transaction fee | Percentage charged per payment processed | 0.1% – 1% |
| Network (miner) fee | Blockchain confirmation cost, passed through or absorbed | Variable by chain |
| Conversion fee | Spread applied when converting crypto to fiat or stablecoin | 0.25% – 0.8% |
| Withdrawal fee | Cost to move settled funds out of the gateway | Fixed or percentage |
| Chargeback / refund fee | Administrative cost when reversing a transaction | $0 – $5 per reversal |
The transaction fee is usually the headline number. Platforms advertise “0.5% per payment” and that sounds straightforward until you discover there is also a conversion spread on top, or network fees are passed directly to the merchant during periods of high blockchain congestion. The real question is what the all-in cost looks like for your typical transaction size and volume.
NOWPayments Fee Structure
NOWPayments operates as a non-custodial payment processor, which means funds pass through its infrastructure but never sit in the company’s wallets. This design affects how fees are calculated and whether the platform can offer certain pricing tiers.
Base Transaction Rates
NOWPayments charges a flat 0.5% fee on most crypto-to-crypto transactions. This rate applies regardless of the coin being sent — Bitcoin, Ethereum, Solana, or any of the 200+ supported tokens. There is no volume discount built into the standard tier, but the fixed percentage keeps things predictable for businesses of any size.
For merchants processing over $50,000 monthly, negotiating custom rates is possible through direct contact with the sales team. This is not a self-serve feature; you need to reach out and get a tailored quote.
On-chain Network Fees
Network fees are handled differently depending on the integration method. When using the NOWPayments widget or hosted checkout page, the platform absorbs the miner fee for smaller transactions and passes it only when the underlying blockchain cost exceeds a defined threshold. With the API integration, merchants can choose to pass network fees directly to customers at checkout, effectively eliminating that cost entirely.
This flexibility matters most for low-ticket stores selling digital products under $10. Absorbing network fees on small orders eats into margins faster than the 0.5% transaction cut.
Currency Conversion Costs
If a customer pays in an altcoin and you want to receive USDT, BTC, or USD, NOWPayments applies a conversion spread on top of the base transaction fee. The spread typically ranges from 0.25% to 0.5% depending on liquidity conditions at the moment of conversion. During volatile market periods this can widen slightly, though the platform generally maintains competitive rates compared to centralized exchanges.
No Hidden Charges
NOWPayments does not charge account setup fees, monthly subscriptions, withdrawal fees, or minimum balance requirements. You do not pay anything unless a transaction goes through. For new businesses testing whether crypto payments make sense for their audience, this zero-fixed-cost model removes financial risk from the equation.
Plisio Fee Structure
Plisio positions itself as a lightweight payment processor focused on simplicity and speed rather than an extensive feature set. Its fee model reflects that philosophy.
Standard Transaction Fees
Plisio charges between 0.4% and 0.6% per transaction depending on the selected plan. New merchants start on the basic tier at 0.6%, while established businesses processing consistent volume can qualify for the 0.4% rate after manual approval. Unlike some competitors, Plisio does not publish a transparent volume-based pricing table — rate changes require contacting support and going through a review process.
Additional Cost Layers
Beyond the base transaction cut, Plisio applies a 0.3% fee on currency conversions. This is separate from the transaction fee and stacks on top, making the effective cost of accepting a random altcoin and receiving stablecoins closer to 0.7%– 0.9%.
Withdrawals from Plisio to external wallets carry a small fixed fee that varies by coin. For Bitcoin, this typically runs around 0.0005 BTC per withdrawal, while Ethereum withdrawals average approximately 0.002 ETH. These amounts fluctuate with network conditions and are adjusted periodically without extensive advance notice.
Plan-Based Features
Plisio offers three tiers: Basic, Pro, and Enterprise. The Basic plan includes standard payment processing with the highest transaction fee. The Pro plan requires verification and monthly volume thresholds, offering reduced rates and priority support. Enterprise pricing is fully custom and targets high-volume merchants needing dedicated infrastructure. Each upgrade requires manual application rather than automatic qualification.
Comparing Total Cost of Ownership
Headline transaction fees tell only part of the story. Here is how the two platforms compare when you factor in the most common scenarios.
| Scenario | NOWPayments | Plisio |
|---|---|---|
| Customer pays BTC, you receive BTC | 0.50% | 0.40% – 0.60% |
| Customer pays LTC, you receive USDT | ~0.75% | ~0.70% |
| Customer pays ETH, you receive USD | ~0.75% | ~0.70% |
| Monthly fixed costs | $0 | $0 |
| Account setup fees | $0 | $0 |
| Custom rate negotiation | Available for $50k+/month | Available via support |
The numbers shift depending on exact conversion timing and blockchain network conditions, but they illustrate a consistent pattern: Plisio’s base transaction fee can be slightly lower on the Pro tier, while NOWPayments maintains a simpler, more predictable structure with fewer variables to track.
Which Platform Saves More Money
The answer depends entirely on your transaction profile. If you accept many different altcoins and frequently convert them into stablecoins or fiat, NOWPayments’ straightforward 0.5% plus conversion spread model is easier to predict and budget for. Merchants who value transparency over marginal savings tend to prefer this approach.
If you primarily process payments in major coins like BTC, ETH, or USDT and qualify for Plisio’s Pro tier at 0.4%, you might save a fraction of a percent per transaction. Over thousands of payments, that adds up. However, you trade some predictability for those savings — rate changes require manual intervention, and withdrawal fees vary by coin on a schedule you do not control.
High-volume merchants should request quotes from both platforms and run the numbers against their actual transaction mix. The difference between 0.4% and 0.5% becomes substantial when you are processing $100,000 or more in crypto payments each month.
Red Flags to Watch For
Regardless of which platform you choose, several practices signal potential problems down the line. Be cautious of gateways that hide conversion spreads behind vague language like “competitive exchange rates.” Transparent platforms disclose their spread explicitly. Also watch for withdrawal limits that force you to keep funds sitting in the processor’s custody longer than necessary — extended custody periods introduce counterparty risk that no fee discount compensates for.
Finally, test the refund and dispute process before you need it. Some platforms charge steep fees for reversals or take days to process them, which frustrates customers and creates operational headaches during peak shopping periods. Both NOWPayments and Plisio handle refunds within reasonable timeframes, but verifying current policies directly with each provider before committing remains the safest approach.
