Payment and payout fees
The acceptance fee depends on the payment method and uses the order base price. Kevmi’s commission is included. VAT and payout fees are shown separately.

Accepting one payment#
Add the percentage and fixed components. For a $5 card order, the fee is $0.50 + $0.50 = $1. VAT is $0.80 and is separate from this fee.
The platform share, approximately 5% on average, is already built into these terms. Do not add a second platform percentage.
| Method | Percentage | Fixed fee | VAT |
|---|---|---|---|
| International cards | 10% | $0.50 | 16% of the base price |
| Alipay | 10% | $0.50 | 16% of the base price |
| SBP | 8% | None | None |
| Cryptocurrency | 4% | None | None |
Withdrawing funds#
The source of funds and payout network are separate settings. Using TRC20 does not make every payout fee the same. The payout fee is separate from the acceptance fee.
Keep the fixed fee in its stated currency. Do not deduct RUB 400 from a USD amount or assume $3 equals 3 USDT. The final payout requires an explicit conversion quote.
| Source of funds | Payout fee | Destination |
|---|---|---|
| Cards | 4% | USDT TRC20 |
| Alipay | 4% | USDT TRC20 |
| SBP | 5% + RUB 400 | USDT TRC20 |
| Cryptocurrency | 0% + $3 | USDT TRC20 |
Calculation precision#
Invoice amountMinor is an integer: 500 means 5.00 USD, RUB or USDT in the explicitly stated currency. These are invoice calculation units; USD and USDT are not automatically converted. Fees and VAT use separate half-up rounding.
For a crypto transfer, use the exact decimal coin amount and network returned by the created operation. Do not derive the transfer amount from the rounded invoice price. A calculation cannot produce negative merchant proceeds.
feeMinor = roundHalfUp(baseMinor × rate / 100) + fixedMinor
vatMinor = roundHalfUp(baseMinor × 16 / 100)
// For SBP and cryptocurrency, vatMinor = 0Check before paying#
