CIS subcontractors & construction trades

The Key Difference: CIS Support
QuickBooks Self-Employed — the plan most sole traders use — has no CIS support at all. If you're a CIS subcontractor, you'd need to upgrade to at least the Simple Start plan at £30/month and then configure CIS manually, which requires accounting knowledge.
FlashBill handles CIS on every plan, including the free one. Select the deduction rate (0%, 20% or 30%), and the correct amounts are calculated and shown on the invoice automatically.
Pricing for UK Tradespeople
QuickBooks Self-Employed costs £10/month but won't do CIS. QuickBooks Simple Start (with CIS) costs £30/month. FlashBill Starter with full CIS costs £9/month — a third of the price.
When QuickBooks Makes Sense
If you're a sole trader who doesn't deal with CIS, and you want help tracking mileage, connecting your bank account, and preparing for Self Assessment, QuickBooks Self-Employed is reasonable. It does those things well. But if CIS is part of your working life, it's the wrong tool.
