Add the modules you need
Per user, per month, on top of the flat core fee — pay for exactly the seats each module needs. Switch any module on or off whenever you like.

Comms is included free for your whole team, on every plan — no seats to count.
No setup fee. Nothing upfront.
Most business software charges an implementation fee before you've done a thing — often thousands, on top of the subscription. We don't. We open your account with your chosen modules and one free admin login, so you can import your data and build your workflows first. Your monthly price starts when you add your second user — when your team actually comes on.
Seats, per module
Not everyone needs every module. Tell us the mix you need — 15 HR seats, 5 CRM seats, whatever fits your team — and we'll set that allocation up for you. Need to add or drop seats later? Just ask, and it applies from your next billing cycle.
AI assistant, included
Every plan includes a built-in AI assistant with a monthly token allowance that scales with the modules you enable — 40,000 tokens per enabled module, per month. Need more? It tops up automatically at £1 per extra 1M input tokens and £5 per extra 1M output tokens — a transparent price barely above what it costs us to run.
OpSemble Complete
Every paid module, one price — instead of £59/user when bought individually. Comms is free either way.
What that adds up to
Three teams of the shape we usually see, priced straight from the rates above. Yours won’t match exactly — that’s what building your plan is for — but there is nothing in these totals that isn’t on this page.

Price a plan like thisEvery line is the published rate — the flat £29 core fee, plus the seats each module actually needs. Once someone needs most of the modules, Complete at £39/user comes out cheaper than adding them up: those same 25 people on every paid module would be £1,004/month on Complete, against £1,504 bought individually. Building your plan does the swap for you and tells you which way is cheaper. All prices exclude VAT.
The maths on a typical 20-person business
Running sales, projects, HR, safety and training on separate tools adds up fast — in cost, logins and copy-paste.
| Need | Typical standalone tool | Typical list price | 20 users |
|---|---|---|---|
| CRM | e.g. HubSpot Sales Starter | ~£18/user/mo | £360 |
| Projects | e.g. monday.com Standard | ~£11/user/mo | £220 |
| HR | e.g. BrightHR (quote-based, est.) | ~£5/user/mo | £100 |
| Health & Safety | e.g. Mitti (formerly SafetyCulture) Premium | ~£19/user/mo | £380 |
| Training | e.g. a typical eLearning/LMS provider | ~£8/user/mo | £160 |
| Five tools, five logins, five invoices, no shared data | ~£1,220/mo | ||
| OpSemble Core (£29 flat) + CRM, Projects, HR, H&S & Training (£38 × 20 users) | £789/mo | ||
Around 35% less — before counting the hours saved by having one login, one support contact, and data that flows between modules (training completions updating HR records, safety actions linked to incidents, quotes linked to deals). Competitor figures are approximate list prices at the time of writing, converted and rounded; actual pricing varies by plan, billing period and seat count. They are examples of well-known tools in each category, not like-for-like feature comparisons.
