Pricing that protects your margin.
A1 OS is an AI operating system for commercial subcontractors — not job-management software. An AI workforce that finds the right work, protects the commercial position, and runs the business with director control. Variations captured, applications submitted on time, cash tracked every day, and the admin that eats your evenings done overnight as drafts awaiting your approval. Choose your plan below or start a 14-day free trial.

Before you start your trial.
Can I start with a free trial?
Yes. Every plan includes a 14-day free trial with assisted rate loading and your live email connected. No credit card required to begin.
Who is A1 OS for?
Commercial subcontractors and specialist trades — roughly five to fifty people — running multiple live projects with applications, variations and retention. Directors who still do too much of the admin themselves.
Is this for domestic jobs?
No. Domestic work is well served by job-management apps. A1 OS is built for valuations, applications, evidence and contract exposure.
Does it replace our accounting software?
No. It runs the commercial side up to the money and works alongside your accounts package — it does not try to be your ledger.
Can site teams use it on mobile?
Yes — and they should. Field Operations is camera-first and built for gloves and site light. Pricing is per company precisely so you can put it on every phone.
What happens after the trial?
You review what the AI workforce prepared — tenders priced, quotes drafted, chases prepared, variations captured, applications tracked. If it pays for itself, you select your plan.
What about additional seats?
Management seats are £25/month each and field seats are £5/month each. External clients and subcontractors are always free.
