Service overview

Our services
in detail

From payment integration to accounting export – everything for professional crypto payments.

Payment integration

Payment Integration

What this service is

We help businesses accept cryptocurrencies as payment – whether in e-commerce, via direct B2B payments or through API integration into existing systems.

Why this matters

Without professional integration, security gaps, booking errors and poor user experience arise. Poor shop integration leads to cart abandonment and technical problems.

What’s included

  • E-commerce platforms (WooCommerce, Shopify)
  • Custom API integrations for B2B & direct payments
  • Multi-currency support (BTC, ETH, USDC, etc.)
  • Automatic price conversion & real-time payment confirmations
  • Checkout optimization

Your concrete benefit

✓New customer groups & international reach
✓Seamless integration into existing systems
✓Low transaction costs
✓Optimised conversion, fewer abandonments
Ramps

On- & Off-Ramps

What this service is

We integrate services that enable the exchange between traditional currencies and cryptocurrencies.

Why this matters

Without ramps, users rely on external exchanges – increasing friction and lowering conversion.

What’s included

  • Fiat-to-crypto purchases
  • Crypto-to-fiat payouts
  • KYC-compliant provider integration
  • Multi-currency support

Your concrete benefit

✓Better user experience

POS

POS Solutions

What this service is

We implement crypto payments for physical points of sale – from tablet terminals to integrated cash register systems.

Why this matters

In brick-and-mortar retail, payment must be fast and seamless – otherwise frustration arises for customers and staff.

What’s included

  • Mobile POS terminals
  • QR code-based payment
  • Integration into existing registers
  • Offline-capable solutions

Your concrete benefit

✓Fast settlement
✓Easy operation
✓Offline capability
✓Professional appearance
Reporting

Settlement & Reporting

What this service is

Why this matters

Without structured reporting, booking errors, compliance issues and high manual effort arise.

What’s included

Your concrete benefit
