bookd. doesn't just file payroll. Every run produces a SHA-256 locked audit pack — worker status, deductions, holiday entitlement, CIS verification — built automatically, before anyone asks for it.
Files RTI. Sends payslips. Marks the job done. It was built for an older set of rules, in a world where the liability stayed where it started.
Every payroll run is treated as a compliance audit. The payslip is the output. The evidence pack is the product.
Same payroll. Different level of protection. Built for the world that exists now, not the one from 2018.
Every run produces a timestamped, SHA-256 locked evidence pack. Not because you asked. Because when HMRC or a claimant's lawyer arrives, the file is already built.
Under the Finance Act changes, unpaid tax liability travels up the supply chain. Agencies, contractors and umbrella operators are now in the frame. bookd. evidences every penny, every decision, every run.
The Fair Work Agency launched April 2026. The 12.07% flat rate is wrong for variable pay workers. bookd. calculates the true 52-week rolling average and flags every discrepancy — automatically.
The same compliance engine surfaces the risk that matters most to you.

CIS compliance →Most bureaus produce payslips. bookd. produces evidence. Every run is sealed with SHA-256 integrity verification — a tamper-evident record of every decision, deduction, and status call, to the penny, at the time it was made.
The 52-week rolling average has been mandatory since 2020. Most bureaus still flat-rate at 12.07% because it's hard to automate. The FWA now has enforcement powers — and variable-hours workers in hospitality, agencies and construction are the first in the firing line.
