How to choose
If you issue fewer than 1,000 invoices annually, Zoho Invoice's free tier is sufficient; exceeding this limit requires a paid upgrade.
Non-CIS sole traders can use QuickBooks Self-Employed at £10/mo, but CIS contractors must upgrade to Simple Start at £30/mo for compliance.
Choose QuickBooks Self-Employed (£10/mo) if mobile receipt capture and bank feeds are your primary workflow needs.
Wave offers free core accounting, while QuickBooks Solopreneur costs $20/month; choose Wave if you can tolerate limited integrations.
Our verdict
QuickBooks Solopreneur is the top choice for US sole traders due to its specific Schedule C categorization and automatic mileage tracking, while QuickBooks Self-Employed offers the best value for UK non-CIS traders at £10/mo.
