For self-employed · Sole traders · CIS subbies

The self-employed moat
The parts your
accountant does at year-end.
Do them now, all year, with 5-second logging. Fewer receipts lost, less stress in January.
Expenses Hub
Mileage + 6 categories + receipts
Business mileage (HMRC 45p/25p auto-split), materials, tools/PPE, phone, training, subsistence, other. Snap receipts from your phone camera. Everything drops your set-aside in real time.
CIS mode
Construction 20% / 30% + materials split
Registered subbies: 20% (or 30% unregistered) CIS deduction at source. Log materials/plant hire inline on the pay period card — HMRC exempts them from CIS, Clok shows exactly what you save.
Set aside tracker
Class 4 NI + Income Tax, live
Every shift you log, Clok annualises your profit and shows the running HMRC bill. When CIS is deducted at source or expenses log, "set aside remaining" drops so you know what to keep back.
HMRC mileage
45p for the first 10k. 25p after.
Simplified Expenses done right. Clok tracks the 10,000-mile threshold across the tax year — cross it mid-year and the rate drops on the next log automatically.
Invoices & payslips
PDF invoices + Self Assessment ready
Generate a proper A4 invoice with your details baked in. Payslip PDF shows all deductions + expenses claimed line so your accountant can just plug in the numbers.
