Pricing

Published, per agency, by contractor count

Almost nothing in this market publishes a price. The back office that comes free with your funding costs one to three per cent of invoice value and is never quoted; the timesheet vendors bill per sheet, including the ones your client sent back. Here is the whole rate card, and what sits behind each number.

Free

£0

Up to 3 active contractors. The whole system, not a trial: the same evidence chain, the same audit trail.

No card
Starter

£99 /mo

Up to 10 contractors. The first desk that has more compliance than one person can hold in their head.

£9.90 each
Core

£199 /mo

Up to 25 contractors. The band most agencies we talk to are in, and the one this was designed around.

£7.96 each
Growth

£399 /mo

Up to 60 contractors. Several consultants, more than one umbrella in the chain, a real quarterly return.

£6.65 each
Scale

£699 /mo

Up to 150 contractors. Beyond that the shape of the problem changes and so should the conversation.

£4.66 each

Excluding VAT. Over a tier's ceiling it is £5 per contractor per month rather than a jump to the next tier.

Why contractors and not seats

The work this system does scales with the number of people on assignment, not with the number of people who log in. Charging per seat would mean an agency paying to let its own bookkeeper see an invoice, which is a tax on using the thing properly. So a consultant, a director, the accountant and anyone else you want in there are included at every tier, and the number that moves the price is the one that also moves the compliance burden.

Two models are deliberately not used here. Per timesheet is what most of this market runs on, and it charges you again when a client rejects a sheet and the worker resubmits it. A percentage of invoice value is the financing model, and it is not a software price at all.

What every tier includes

All of it. There is no tier where the compliance half is switched off, because the compliance half is the reason the product exists and a cheaper version without it would be a fourth timesheet tool.

The chainPlacement, timesheet, invoice, Key Information Document, status determination, umbrella check, held as one record rather than six systems that agree by hand.
Both invoice seriesSelf-billed purchase invoices under HMRC Notice 700/62 and your own sales invoices, raised from the same client-approved week, each sequential, with Xero exports for both.
The statutory artefactsKIDs under regulation 13A, right-to-work records with method and date, AWR clocks that understand breaks and pauses, the reg 21 assignment confirmation, and the quarterly intermediaries return built from placements.
The umbrella registerEvery umbrella you pay through, its evidence file, expiry chasing, and the placements running through it. Since 6 April 2026 this is the only protection there is.
Four facesStaff desk, client portal, worker portal and job board, all reading and writing the same record.
The audit chainHash-chained, never edited, never deleted, and assembled into an evidence pack for a placement in one click.
Getting in and outThe importer reads your own column headings. The offboarding bundle hands the whole tenant back, round-trip verified, whenever you ask.
SupportIncluded. Some vendors in this market bill £45 to £80 per phone call, which teaches people not to ring when something is wrong.

What is not in the price

What it replaces

The comparison worth making is not against one product, because no single product does this. An agency covering the same ground today is usually paying two vendors that do not talk to each other.

TodayRoughlyWhat it does not do
A back-office or timesheet system£98 to £129 a month at this sizeNo KID generation, no umbrella register, no intermediaries return
Plus a compliance platform£99 to £299 a monthNo timesheets, no invoicing, so the rate data is rekeyed by hand
Both, unconnected£197 to £428Nothing holds the join, which is the thing an inspection asks about

Core is £199 and holds the join. That is the argument, and it only stands because KID generation, the umbrella register and the intermediaries return are in the product now rather than on a roadmap.

If your funder gives you a back office free

Many agencies at this size fund their payroll through an invoice financing provider, and the back office arrives with it: pay, bill, chase, credit control, bad debt cover. That is genuinely valuable and this does not replace it. We have read what those providers publish, and none of it mentions Key Information Documents, right to work, AWR, umbrella due diligence, IR35 or the intermediaries return.

Their back office is money-shaped. This one is evidence-shaped. They move your money. The question is who is holding your proof, and if the answer is a folder and somebody's memory, that is what this costs to fix.

Honest about the stage

Two things you should know before deciding, because finding them out later would be worse.

Early agencies get founder pricing held for 24 months, and the terms are written down before anything starts.
