What Tradespeople Should Look For
1. Rugged & Durable Build
Job sites are tough on equipment. Look for water-resistant (IP54 rating minimum) and drop-proof terminals. SumUp readers and Square Terminals both survive typical job site conditions.
2. Long Battery Life
You can't charge between jobs. Essential battery specs:
- SumUp Air: 500 transactions per charge (multiple weeks)
- Square Reader: Full working day (8-10 hours)
- Zettle Reader 2: 8 hours continuous
3. Offline Transaction Processing
Critical for trades working in basements, rural areas, or locations with poor signal. SumUp stores unlimited transactions offline via Bluetooth, syncing when you return to WiFi. Square and Zettle also cache payments.
4. Digital Receipts
Eliminate the need for printer and thermal paper. Email/SMS receipts are professional, eco-friendly, and customers prefer them (can file digitally for tax/warranty). All major providers support digital receipts.
5. Invoicing Capability
For larger jobs (£500+), sending professional invoices with integrated payment links streamlines collection. Square Invoices and SumUp Invoices are both free and allow deposit collection.

- Cheque: 5-7 days to clear after receiving
- Bank transfer: 1-3 days if customer pays promptly

Do Tradespeople Need Contracts?
No. Unlike retail businesses, tradespeople benefit from no-contract providers:
- SumUp: No contract, cancel anytime
- Square: No contract, pay-as-you-go
- Zettle: No contract, month-to-month
This flexibility is perfect for trades where business volume fluctuates seasonally or by project availability.
Common Tradesperson Questions
Do I need WiFi to accept card payments on-site?
No. Mobile card readers work via smartphone Bluetooth connection. Your phone provides the internet connection (WiFi, 4G, or 5G). Even without signal, terminals store transactions offline and sync later.
Can I take deposits before starting work?
Yes, and you should. Use payment links (Square, SumUp) to collect 30-50% deposits. This protects you from customer cancellations and improves cash flow for materials purchasing.
What if a customer disputes the charge?
Card disputes (chargebacks) are rare in trades (under 0.5%). Protect yourself by: Getting signed quotes, taking before/after photos, sending itemized invoices. Most providers support you in disputes if you have documentation.
Do I need a business bank account?
Yes. All UK card machine providers require a business bank account in your trading name. Sole traders can use accounts in their personal name if trading under their own name.
How long until I receive payment?
Next working day for most providers (Dojo, Square, SumUp). Some offer same-day settlement for a fee. Significantly faster than 30-day invoice terms common in trades.

- Digital transaction records - All sales automatically logged
- VAT reporting - Automatic VAT calculations and reports
- Export to accounting software - Square, SumUp integrate with Xero, QuickBooks
