Bookd helps UK construction contractors manage subcontractor verification, CIS deductions, monthly returns, statements and HMRC filing through a controlled workflow built for the realities of construction.
CIS usually goes wrong because the process is loose. A subcontractor starts before their details are checked. A UTR is missing. Materials are not separated properly. A deduction rate is assumed. Statements are left until later. The monthly return becomes a scramble.
Bookd's view is simple: CIS should be managed like payroll. Data in. Verification checked. Deductions reviewed. Client approval captured. CIS300 filed. Statements issued. Evidence retained.
That is the difference between admin and control.
Bookd turns CIS from scattered subcontractor admin into a controlled monthly compliance workflow.
A practical operating framework covering every part of monthly CIS: who CIS affects, how verification works, deduction treatment, the 12-step monthly control process, common mistakes and when to outsource. The full picture in one place.
