The trade-offs
Strengths and Limitations
BOOK ON
Strengths
- One published rate of £2.95 per worked officer, with all platform features included
- Controllers, managers and office users are not counted towards the bill
- Approved shifts feed timesheets, payroll and client invoices from the same record
- SIA licence, BS 7858 vetting and right-to-work records held against each officer
- Officer app for iOS and Android for booking on, check calls, patrols and incident reports
Limitations
- Licensing and vetting records are built around UK security rules (SIA, BS 7858, ACS)
- Exports to accounting and payroll packages are confirmed per package during onboarding rather than listed
- Minimums, setup and contract length are set in each company's commercial agreement, not on the pricing page
- The vendor states its records support SIA, ACS, BS 7858 and ISO work but do not award certification or guarantee compliance
eResource Scheduler
Strengths
- Billed per resource rather than per user, and archived resources drop out of the count
- Modules are bought individually, so a team that only needs the schedule does not pay for timesheets or financials
- Requests are matched to people by skill and ranked with a match score, with gap reporting on requested against assigned
Limitations
- No task breakdown; it books people to projects rather than to tasks
- Timesheets, financials, forecasting and single sign-on are all priced on top of the core module, so the entry price is not the running cost
- Google Calendar, Outlook Calendar and n8n integrations are announced as coming rather than shipped
Plans

How we check reviews
Before sending, the author has to confirm three things: that they have used the product themselves, that they work neither for the vendor nor for a competitor, and that nobody is paying them for the review. We also ask whether the vendor invited them to write it. That answer is required, either answer is accepted, and it stays with the review.
Every review is read by a person before it appears. An email address is required and is confirmed: we send a link to it, and a review does not reach us until the author opens that link, so a review has a sender who was reachable at least once rather than being anonymous. Where what somebody writes needs backing, we ask them for evidence that they used the product, and a review that does not get it is not published. We publish positive and negative reviews alike, we pay nothing and offer nothing for a review, and we accept none that was bought or incentivised.
What we cannot do is verify a purchase. There is no shop here and no account, so whether the author really used the tool rests on their own declaration, on whatever we ask them for, and on the plausibility of what they write. We say so rather than implying a check that does not exist.
A vendor cannot buy a review, and cannot have one removed or changed because they dislike it. We remove or edit a review only if it breaks our rules or the law, for example a false statement of fact. Paid placement has no effect on which reviews appear or on any score.
