The back office for contract recruitment

BookKept holds one record from vacancy to paid invoice: the placement, its weeks, both invoices, the paperwork and the proof, joined. Built for UK agencies running contractors, where the compliance is the work.

What it holds

• Key Information Documents under regulation 13A, right-to-work records, AWR clocks and umbrella evidence for joint and several liability, each rule cited next to the thing it governs.
• Self-billed purchase invoices under HMRC Notice 700/62 and your own sales invoices, raised from the same client-approved week.
• Every compliance-relevant action on a hash-chained audit trail, assembled into an evidence pack in one click.
• Compliance rules as dated configuration, so the 1 October 2026 right-to-work reform arrives on its own date rather than in a release.

The rules are about to change again

Joint and several liability for umbrella payroll failures is already in force, right-to-work checking changes on 1 October 2026, umbrella regulation lands from April 2027, and Make Work Pay is still in consultation. The guides below set out what each one asks and what your records must show.

• The compliance timeline, 2026 to 2027
• Right-to-work checks from 1 October 2026
• Umbrella compliance and joint and several liability
• IR35 and where the fee-payer risk sits
• All compliance guides
