For subcontractors

Job management for subcontractors, in one app.

Get paid right, and keep your CIS in order. Subcontracting is its own admin job on top of the actual work. CIS to get right, materials to keep out of the deduction, invoices to raise and a year of statements to hold onto for the refund. Sitewise keeps the whole of the subcontractor's side in one place, so the money that lands is the money you expected and year end is already added up.

The admin that eats your week

CIS eating your cash flow

Stuck on the 30% rate, or letting CIS come off your materials, so money sits with HMRC all year that should be in your account.

Invoices and statements everywhere

Splitting labour and materials by hand, retyping the same figures, then hunting for deduction statements when the tax return lands.

No clean record of your pay

Days worked scattered across texts, and no tidy proof of what you were paid or what was deducted on each job.

How Sitewise helps

One app for the subcontractor's side of the job

  • CIS worked out on the labour. Sitewise splits labour and materials and works the 20% deduction out for you, so none of your material money gets tied up with HMRC by mistake.
  • Every deduction statement kept. Each payment and deduction statement is filed against the job, so at year end your totals are already added up for the refund.
  • Invoices straight from your hours. Raise a CIS invoice from the work you logged, with labour, materials and the net figure shown before you send.
  • A clean record, all in one place. Hours, invoices, materials and CIS sit on the job they belong to, which is exactly what keeps you compliant and paid on time.

Subcontractors and Sitewise: common questions

Is there a job management app for subcontractors?
Yes. Sitewise is built for UK subcontractors and trades to run CIS, invoices, hours, materials and records in one place, rather than across paper, spreadsheets and group chats. It is in development, and you can join the waitlist for early access.
Does Sitewise handle CIS for subcontractors?
Yes. It works out the CIS deduction on the labour, splits labour and materials on invoices, and keeps every payment and deduction statement against the job, so year end is far simpler. The free CIS deduction calculator shows what actually lands in your account.
Can it help me claim my CIS deductions back?
Sitewise keeps every deduction statement filed against the job, so when you file your Self Assessment your total CIS deductions are already added up and simple to set against your bill.
When can I use Sitewise?
Sitewise is not yet generally available. Join the waitlist and we will let you know the moment early access opens, and you will be among the first in.
