Bookd handles subcontractor verification, CIS deduction calculations, CIS300 filing, deduction statements and deadline control through a structured monthly workflow built for UK construction firms.
Most construction firms are not doing CIS wrong on purpose. The process is just weak — and the weaknesses compound every month.
A controlled CIS process should answer five questions every month: who did we pay, were they verified, what deduction treatment applies, what was subject to CIS, and is the return filed and evidenced? Most firms cannot answer all five cleanly.
The rate must come from verification and current records — not from assumption, habit or subcontractor pressure. Gross payment status should never be guessed. If a subcontractor says they are gross, that needs to be confirmed through HMRC before the payment runs.
CIS should not be rebuilt from scratch every month. Bookd gives contractors a repeatable 10-step workflow: subcontractor data in, verification checked, deduction treatment reviewed, return approved, HMRC filed, statements issued and evidence retained.
Bookd uses its own operating workflow to track every part of the monthly CIS cycle. Nothing relies on memory or inbox management. Every period has a clear status from open to closed.

Many CIS subcontractors and sole traders will need cleaner digital records as MTD for Income Tax expands. Bookd is building CIS, payroll and MTD workflows together so construction firms are not dealing with disconnected systems when the obligations arrive.
CIS payroll refers to the process of managing subcontractor payments under the Construction Industry Scheme. It includes subcontractor verification, CIS deduction calculations, monthly CIS300 returns, payment and deduction statements and HMRC reporting.
Yes. Before paying a new subcontractor, you must verify them with HMRC. HMRC tells you what deduction rate applies: gross (0%), standard (20%) or higher (30%). If you skip verification, you are guessing the deduction treatment — which creates risk for your monthly return.
CIS300 is the monthly return contractors file with HMRC to report subcontractor payments and CIS deductions made during the tax month. It is the central monthly reporting obligation under the Construction Industry Scheme.
Yes. Bookd is designed to support construction firms with both PAYE payroll and CIS workflows within one monthly rhythm — covering payslips, FPS/EPS, CIS returns, deduction statements and HMRC filing.
A CIS payment and deduction statement is issued to a subcontractor after each tax month. It shows what they were paid, what was deducted and the tax month covered. Subcontractors rely on these for their own tax records and should receive them consistently — not only when they chase.
