SumUp for Swiss Freelancers: Is It Right for Your Business?
The complete guide to mobile payment processing in Switzerland. Compare pricing, features, and learn how to integrate with your accounting workflow.

As a Swiss freelancer, you've probably experienced this: A client wants to pay with a card, but you only have your bank details ready. Or worse—you lose a sale because you can't accept payment on the spot.
Payment acceptance is one of those unsexy administrative tasks that can make or break your freelance business. Traditional Swiss payment terminals come with hefty monthly fees and long-term contracts. But what if there was a simpler way?
Enter SumUp—the mobile payment solution that's gained popularity among small businesses and freelancers across Europe. But does it actually work well in Switzerland's unique payment landscape? And how can you integrate it with your accounting workflow?
Let's find out.
What SumUp Offers Swiss Freelancers
SumUp provides mobile card readers and payment processing designed for small businesses. No monthly fees. No long-term contracts. Just pay-as-you-go transaction fees.

Online invoicing tools and reportingSumUp Pricing in Switzerland (2026 Update)
Let's cut through the confusion about SumUp's pricing. You'll see different numbers quoted online, but here's what actually applies in Switzerland today:
Standard Pay-As-You-Go Model
Transaction fees:
- 1.5% for debit card transactions
- 2.5% for credit card transactions (Visa/Mastercard)
- No monthly subscription fee
- No hidden charges
Hardware costs:
- SumUp Air (basic card reader): CHF 99 one-time purchase
- SumUp 3G (with built-in SIM and printer): Higher upfront cost
- No rental fees—you own the device
Example calculation: If you process CHF 3,000 in monthly transactions (split 50/50 debit/credit), you'll pay approximately CHF 60 in fees.
SumUp One Subscription Model
If you process higher volumes, SumUp offers a subscription plan:
"Bezahlungen Plus" pricing:
- 0.99% for Swiss consumer cards
- 1.99% for other cards
- CHF 29 monthly subscription fee
Break-even point: This makes sense if you process over CHF 3,000 monthly in mostly credit card transactions.
The bottom line: For most freelancers doing under CHF 5,000 monthly in card transactions, the standard model works better. No fixed costs means you only pay when you actually get paid.
The Big Swiss Payment Gap: No TWINT or PostFinance
Here's what you need to know upfront: SumUp doesn't support TWINT or PostFinance Card—two of Switzerland's most popular payment methods.
What this means for you:
If your clients are primarily Swiss consumers who prefer these local payment methods, SumUp might not be the best fit. You'll accept international cards just fine, but you'll miss out on customers who only use TWINT or PostFinance.
When SumUp still works:
- You have international or corporate clients who typically use Visa/Mastercard
- You offer services where clients expect to use credit cards
- You work at events or markets alongside other payment methods
- Your transaction volumes are too small to justify traditional terminals with monthly fees
The key is understanding your client base before committing.
SumUp Hardware Options Explained
SumUp offers several card reader models. Here's what matters for Swiss freelancers:
SumUp Air (Solo Lite)
Best for: Mobile freelancers who always have their smartphone
- Connects via Bluetooth to your phone or tablet
- Cheapest option at CHF 99
- Compact and portable
- Requires your phone's internet connection
- Battery lasts for 500 transactions
Ideal if you're: A consultant meeting clients at their offices, a photographer at events, a yoga instructor collecting class fees.
SumUp Solo
Best for: Professionals who want a standalone device
- Works independently—no phone needed
- Built-in 4G SIM card (unlimited data included)
- Touchscreen interface
- Receipt printing via Bluetooth printer (sold separately)
- More professional appearance
Ideal if you're: A craftsperson at weekly markets, a mobile mechanic, anyone who wants to minimize dependence on their smartphone.
SumUp 3G with Printer
Best for: Businesses needing printed receipts
- Integrated receipt printer
- Built-in SIM card for connectivity
- Heavier and bulkier than other options
- Higher upfront cost
Ideal if you're: Required to provide printed receipts, selling at markets where customers expect paper receipts, processing higher volumes.
Our recommendation for most freelancers: Start with the Air. At CHF 99, it's low-risk. You can always upgrade if your needs change.
How SumUp Compares to Alternatives
Let's be honest about where SumUp stands in the Swiss market

The verdict on alternatives:
SumUp vs. Worldline (formerly SIX Payment Services)

SumUp vs. Traditional Bank Terminals

Real Freelancer Scenarios
Let's look at when SumUp makes sense—and when it doesn't.
Scenario 1: Mobile Consultant (IT, Business, Design)
Profile: You visit corporate clients at their offices, invoice CHF 2,000-5,000 per project, occasional same-day payment requests.
SumUp fit: ✓ Excellent
- Carry the Air in your laptop bag
- Accept payment immediately after presentations
- No monthly fees during slow months
- Professional appearance
Magic Heidi value: Invoice before or after meetings, track project time and expenses, prepare for VAT registration as you grow.

SumUp fit: ⚠ Good with limitations
- Solo terminal works independently
- Accept cards from tourists and locals
- Problem: Many Swiss customers prefer TWINT
- Consider carrying a TWINT QR code alongside SumUp
Magic Heidi value: Track market revenue vs. expenses, manage material costs, handle VAT when you exceed threshold.
Scenario 3: Fitness Instructor or Therapist
Profile: Yoga classes, personal training, massage therapy. Monthly memberships plus drop-in sessions. Swiss consumer clients.
SumUp fit: ⚠ Limited
- Many clients prefer TWINT or direct debit
- Credit cards work for tourists and expats
- Consider as backup payment method
Magic Heidi value: Recurring invoice automation, session tracking, expense management for equipment and space rental.
Scenario 4: B2B Service Provider (Electrician, Plumber, Contractor)
Profile: On-site services for homeowners and businesses. Invoice CHF 500-3,000 per job. Older client demographic.
SumUp fit: ⚡ Moderate

Magic Heidi value: Quote-to-invoice workflow, expense tracking for materials, project-based accounting, VAT-compliant invoicing.
The pattern: SumUp works best for freelancers with international clients, mobile work, or credit card-preferring customers. It's less ideal if your client base heavily uses TWINT or PostFinance.

Cost-Benefit Analysis: Is SumUp Worth It?
Let's run the numbers for a typical Swiss freelancer.
Scenario: Freelance Consultant
Monthly payment acceptance:
- CHF 4,000 in card transactions
- 60% debit cards, 40% credit cards
SumUp costs:
- Debit: CHF 2,400 × 1.5% = CHF 36
- Credit: CHF 1,600 × 2.5% = CHF 40
- Total monthly fee: CHF 76
Alternative: Traditional Swiss bank terminal
- Monthly rental: CHF 35
- Debit cards: CHF 2,400 × 2.0% = CHF 48
- Credit cards: CHF 1,600 × 3.0% = CHF 48
- Total monthly cost: CHF 131
Annual savings with SumUp: CHF 660
But remember: This doesn't account for TWINT transactions you might lose by not accepting them.
When SumUp Becomes Expensive
Break-even point: If you process over CHF 8,000-10,000 monthly, traditional acquirers often become more cost-effective, especially if you need TWINT support.
The flexibility value: Even if SumUp costs slightly more, the no-contract flexibility is worth something. During slow months, you only pay transaction fees. Traditional terminals charge you regardless.
Common Questions Answered

Yes. SumUp offers payment links and a basic online store builder. Generate a payment link, send it to your client, and they can pay via browser. The transaction appears in your SumUp dashboard just like in-person payments.
What happens if a client disputes a payment?
SumUp handles chargebacks according to card network rules. If a client disputes a charge, SumUp will notify you and may freeze the disputed amount pending resolution. Keep good records of services delivered—Magic Heidi's invoice and project notes help here.

SumUp primarily accepts Visa and Mastercard. American Express acceptance varies by region and typically carries higher fees. Check your SumUp dashboard for available card types in Switzerland.

Magic Heidi tracks your annual turnover and alerts you when you're approaching CHF 100,000. Once you register for VAT, notify Magic Heidi of your VAT number, enable VAT on all future invoices, and use Magic Heidi's VAT reporting tools for quarterly filings.

Absolutely. SumUp works identically in German, French, and Italian-speaking regions. Magic Heidi offers full multi-lingual support, so your invoices can match your client's language preference.
