## A crypto-to-fiat payment gateway converts stablecoins to bank deposits same day without the 2% to 4% conversion fees that bundled processors charge.

The payment is instant. The fiat conversion does not have to take days or cost a percentage of your revenue.

A customer pays you 99 USDC on Base. The transaction confirms in 2 seconds. The stablecoin lands in your wallet. Now you need dollars in your bank account. How fast and how much does it cost?

BitPay: next business day, included in 1-2% processing fee. CoinGate: next business day, plus 2% to 4% fiat withdrawal fee on top of 1% processing. NOWPayments: 1-3 business days, exchange fees apply. With the right architecture and off-ramp: same day, near-zero cost.

## Two operations most merchants confuse, and why separating them saves thousands

Payment acceptance and fiat conversion are fundamentally separate operations with separate fee structures. Most crypto gateways bundle them into a single service and charge a combined percentage on every transaction. This bundling hides the true cost of each operation and prevents merchants from optimizing.

**BitPay** bundles both operations into its 1% to 2% processing fee. You get fiat settlement next business day. The simplicity is appealing, but you cannot opt out of fiat conversion to hold stablecoins without paying the same percentage.

**CoinGate** charges 1% for payment processing and adds 2% to 4% for fiat withdrawal. Total: 3% to 5% per transaction when you want fiat. That is the most expensive bundled option among major crypto processors.

**NOWPayments** charges 0.5% to 1% for processing and offers auto-conversion to fiat through exchange partners with additional fees. Total cost varies but typically runs 1% to 2.5%.

**Plaitr** separates them completely. Payment acceptance: $99 to $999 per month flat with zero per-transaction fee. Fiat conversion: your choice of off-ramp at your negotiated rate. The [crypto payment gateway](/crypto-payment-gateway) handles the payment. You choose how and when to convert.

This separation gives merchants three advantages: lower total cost, flexible settlement timing, and the option to hold stablecoins (earning yield) instead of converting to depreciating fiat immediately.

## Off-ramp options ranked by cost and speed

### Option 1: Circle Mint (best for USDC above $100K/month)

Circle, the issuer of USDC, offers Circle Mint for institutional redemption. USDC to USD at 1:1 with zero fee above $100,000 per month in redemption volume. Settlement: 1 business day via ACH (US) or SEPA (EU).

Circle Mint is the gold standard for USDC off-ramping. The 1:1 peg means no slippage, no conversion spread, and no fee at institutional volumes. Below $100K/month, a small redemption fee applies (typically 0.1% to 0.25%).

**Best for**: Merchants processing $100K+ per month who settle in USDC and want zero-fee fiat conversion.

### Option 2: Exchange withdrawal (best for flexibility)

Send stablecoins to Coinbase, Kraken, Gemini, Bitstamp, or any major exchange. Convert to USD, EUR, or GBP using the exchange's trading engine. Withdraw to your bank.

Conversion fees: 0.1% to 0.6% depending on the exchange, your volume tier, and whether you use market or limit orders. Limit orders reduce the fee to the maker rate (0.05% to 0.15% on major exchanges).

Settlement: 1 to 3 business days depending on the exchange, withdrawal method, and your bank. Some exchanges offer instant ACH for verified business accounts.

**Best for**: Merchants who want flexibility across multiple stablecoins (USDC, USDT, DAI) and fiat currencies.

### Option 3: Hold stablecoins (best for cost and yield)

Receive USDC or USDT. Do not convert. Hold stablecoins in your wallet and use them directly for business expenses: payroll for international contractors, supplier payments, treasury management.

Growing number of vendors, contractors, and service providers accept stablecoin payment directly. Cross-border supplier payments in stablecoins arrive in seconds instead of days and cost cents instead of $25 to $50 in wire fees.

Stablecoins held in DeFi protocols (Aave, Compound, Morpho) earn 4% to 5% APY as of 2026. A merchant holding $500,000 in stablecoin treasury earns $20,000 to $25,000 per year in yield. Converting to fiat and depositing in a business savings account earns 2% to 3% ($10,000 to $15,000 per year).

**Best for**: Merchants with international expenses, crypto-native operations, or treasury management goals.

### Option 4: Gateway built-in (most expensive)

BitPay and CoinGate handle conversion automatically. You receive fiat in your bank account. The convenience costs 1% to 5% per transaction depending on the processor.

**Best for**: Merchants who prioritize simplicity over cost and process less than $20,000 per month (where absolute fee amounts are small).

## Same-day settlement: how the banking rail determines speed

The crypto side of settlement is instant. On-chain confirmations take 0.4 seconds on [Solana](/accept/solana), 2 seconds on [Base](/accept/base), 3 seconds on Tron, and 12 seconds on [Ethereum](/accept/ethereum). The bottleneck is the banking rail on the fiat side.

**FedNow (US)**: Real-time, 24/7, 365 days per year. Settlement in seconds. Launched July 2023. Over 1,000 financial institutions connected as of 2026. If your bank supports FedNow, stablecoin-to-fiat-to-bank happens same day, any day.

**SEPA Instant (EU)**: Under 10 seconds. Available 24/7 across 36 European countries. Mandatory for all EU banks under the Instant Payments Regulation adopted in 2024.

**ACH (US)**: Same-day ACH settles in 3 to 5 hours during business days. Standard ACH settles next business day. Weekends and holidays add delay.

**SWIFT (International)**: 1 to 5 business days. $15 to $50 per transfer. Correspondent bank deductions of $10 to $30. The slowest and most expensive option.

The combination of instant on-chain settlement and real-time banking rails (FedNow, SEPA Instant) enables true same-day crypto-to-fiat settlement. Plaitr supports both pathways.

## Fee math at $300,000 per month

| Settlement method | Processing cost | Conversion cost | Total annual cost |
|------------------|----------------|-----------------|-------------------|
| BitPay (auto fiat, 1.5%) | $54,000 | Included | $54,000 |
| CoinGate (1% + 3% fiat) | $36,000 | $108,000 | $144,000 |
| NOWPayments (0.75% + exchange) | $27,000 | $10,800 | $37,800 |
| Plaitr + hold stablecoins | $5,988 | $0 | $5,988 |
| Plaitr + Circle Mint | $5,988 | $0 | $5,988 |
| Plaitr + exchange (0.3%) | $5,988 | $10,800 | $16,788 |

A merchant on CoinGate paying $144,000 per year saves $138,012 by switching to Plaitr and holding stablecoins. Even with the most expensive exchange off-ramp, the savings exceed $127,000.

## The custody risk of bundled crypto-to-fiat gateways

When a gateway handles both payment acceptance and fiat conversion, they custody your funds during the conversion window. BitPay holds your crypto until they convert and settle next business day. CoinGate holds funds until SEPA or wire transfer completes.

During that custody window, your funds face counterparty risk: security breaches, regulatory freezes, liquidity events, or account restrictions.

[Non-custodial payment processing](/non-custodial-crypto-payment-processor) eliminates this risk. Plaitr never holds your funds. The payment settles directly to your wallet on chain. You control when, how, and whether to convert to fiat. Your keys, your funds, your timeline.

## Concrete scenario: CloudStack SaaS

CloudStack is a B2B SaaS with $200,000 per month in revenue from 400 business customers across 30 countries. Currently on CoinGate for crypto payments (15% of revenue) and Stripe for card payments (85%).

**Current crypto costs (CoinGate, $30,000/month crypto volume):**
- Processing (1%): $3,600/year
- Fiat withdrawal (3%): $10,800/year
- **Total: $14,400/year**

**With Plaitr ($99/month) + Circle Mint:**
- Processing: $1,188/year
- Fiat conversion: $0 (above $100K/year threshold)
- **Total: $1,188/year**

**Savings: $13,212/year** on crypto payments alone. As crypto adoption grows from 15% to 30% of revenue, the savings double.

## What to do this week

1. [Sign up for Plaitr](/auth/register). $99/month. Zero KYC. 15-minute setup.
2. Accept your first stablecoin payment via payment link or hosted checkout.
3. Decide your off-ramp strategy: hold stablecoins, Circle Mint, exchange, or fiat off-ramp.
4. Compare your total cost (processing + conversion) to your current processor.
5. Read the [stablecoin settlement guide](/blog/receive-crypto-payments-business-stablecoins-fiat-off-ramp) for detailed off-ramp optimization.

The crypto-to-fiat path does not require a percentage-fee gateway in the middle. Separate payment acceptance (flat fee) from fiat conversion (your choice of off-ramp) and the savings compound every month.

## The future of crypto-to-fiat in 2026 and beyond

Real-time banking rails (FedNow, SEPA Instant) are expanding coverage rapidly. By end of 2026, over 2,000 US financial institutions will support FedNow. All EU banks are mandated to support SEPA Instant. This means same-day crypto-to-fiat settlement will be available to virtually every merchant in the US and EU.

The off-ramp market is consolidating around stablecoin-native providers. Circle Mint, Bridge (acquired by Stripe), and institutional exchanges are competing on speed and cost, driving conversion fees toward zero for high-volume merchants. A merchant processing $500,000 per month in stablecoins today pays near-zero conversion fees through Circle Mint. That cost structure will only improve.

For merchants evaluating crypto-to-fiat gateways, the decision framework is straightforward. Choose a processor that separates payment acceptance from fiat conversion. Use flat-fee pricing for payment acceptance. Choose your own off-ramp for fiat conversion. Same-day stablecoin or fiat payout, 100% keep rate, zero KYC.
