Comparison
Commusoft is a serious all-in-one field service platform aimed at UK gas, plumbing, electrical and HVAC businesses. Job management, digital certificates, quoting and invoicing, engineer scheduling, parts and stock, customer database - it's built for established multi-engineer companies that want one system running the whole operation.
Bookso does one thing. It automatically rebooks your existing customers by sending a reminder with a one-tap booking link when their next service is due. That's it - no job management, no certs, no invoicing, no parts.
So these are genuinely different tools at a genuinely different scale and price class, and this page will say so plainly. If you're a multi-engineer firm looking for an operational spine, Commusoft is the right shape of tool. If you're a solo trade or small team whose priority is repeat work rebooking itself for under £15 a month, Bookso is the right shape.

Commusoft is genuinely strong for established gas, plumbing, electrical and HVAC firms with several engineers on the road. The pitch is real: one system for the whole operation - jobs coming in, engineers scheduled, digital certificates completed on site, parts tracked against jobs, invoices out, service contracts and assets kept properly against each customer. If the pain you're solving is operations at scale, it's a good platform and it earns its price.
It's especially well suited to firms with recurring commercial contracts - maintenance visits, service agreements, asset-based work - where you need to know exactly what's been done on which boiler or unit and when the next visit is due against a contract, not just a customer. Bookso doesn't compete with any of that and isn't trying to.
Bookso wins on one very specific thing: the rebooking loop, ending in a confirmed booking rather than just a reminder sent. When a customer's next service is due, Bookso emails them from your business name with a one-tap booking link. They pick a slot, the job lands in your diary as a confirmed booking, and you get notified. If they ignore the first email a chaser goes out automatically, and on paid plans one SMS follow-up too.
It's also priced per business, not per user. A Commusoft-class platform is often overkill and over-budget for a one-person trade with a solid book of regulars - you'd be paying for scheduling, parts, contracts and multi-engineer workflow you don't need. Bookso is £14.99/month on Pro for unlimited customers, no per-user fees, no minimum licences, no contract.
Setup is about 5 minutes: add a customer, pick a service interval, done. And Bookso is designed to complement full field service platforms rather than replace them - it's not trying to be the whole operational spine, just the piece that quietly brings the next job in.
Yes. Larger firms sometimes keep Commusoft for operations - jobs, engineers, certs, invoicing - and add Bookso alongside for the customer-side rebooking loop, especially where they want the confirmed-booking flow with a one-tap link.
Honestly though, if you're already deep into Commusoft, its own reminders may be enough on their own - it's a full platform and the reminders are part of the workflow. Bookso's sweet spot is the solo trade or small team that Commusoft was never really built for: too small to justify a full field service platform, but big enough that repeat work walking out the door genuinely hurts.
The honest framing for Bookso vs Commusoft isn't a feature war - it's a scale difference. Commusoft is enterprise-ish field service management, aimed at firms with multiple engineers, commercial contracts, real operations to run. Bookso is a single-purpose tool priced for a van-and-a-phone business whose main pain is that repeat customers quietly slip away when nobody reminds them the next service is due.
So the right question isn't 'which is better' - it's 'which one matches the size and shape of your business today?' A three or four engineer heating firm running commercial contracts and issuing dozens of CP12s a month is a Commusoft-shaped business. A solo gas engineer or plumber with 150 to 300 regulars on the book, doing their own paperwork on the side, is a Bookso-shaped business. Both are legitimate; they just live in different places on the same trade.
The pricing shape tells the same story. Full field service platforms are priced per user because they scale with your team - the more engineers you put through it, the more it costs, which is fair because that's what it's for. Bookso is priced per business because it scales with your customer list, not your headcount - free for the first 5 customers, £14.99/month on Pro for unlimited customers, £44.99/month on Business if you need a small team. That's why a Bookso-shaped business almost never needs Commusoft, and a Commusoft-shaped business sometimes still adds Bookso for the piece a full platform doesn't focus on: the confirmed-booking rebooking loop.
Only if what you actually need is the rebooking piece. Bookso is a fraction of the price, but it doesn't do job management, digital certificates or invoicing - and it isn't trying to. For a lot of solo trades that's exactly the point: you don't need a full field service platform, you need repeat customers to rebook themselves. If you need the operational spine that Commusoft provides, Bookso won't replace it.
Yes. Some larger firms keep Commusoft for operations - jobs, engineers, certs, invoicing - and add Bookso alongside for the customer-side rebooking loop. There's no direct integration today; in practice you'd add the customer to Bookso when you complete a job in Commusoft, set the service interval, and let Bookso handle the reminder and booking link nearer the next service date.
For pure rebooking on a solo budget, Bookso - it's built around that one loop, priced per business, and running in about 5 minutes. If you're a one-person business but you also need full job management, digital certificates, invoicing and scheduling in one place, look at the full field service suites (Commusoft, Joblogic, Gas Engineer Software and similar) - they're a different shape of tool for a different shape of pain.
No, by design. Bookso doesn't produce or store CP12s, LGSRs or any other certificates. If you need those on your phone, pair Bookso with a dedicated certs tool (Gas Engineer Software, Commusoft, Joblogic or similar) - Bookso stays focused on rebooking your existing customers.
