UK construction SMEs (contractors with 5 to 50 employees) face a specific software problem. The enterprise platforms (primarily Procore) are technically capable but priced and scoped for businesses with £20 million or more in annual revenue. The simpler tools lack the job costing depth, document control, and subcontractor management that even a mid-sized contractor needs. This guide covers what the main platforms actually cost, what features matter most for SMEs, and where the gaps are.

| Product | Pricing | Best for | Main limitation |
|---|---|---|---|
| Procore | Quote only (enterprise) | Larger contractors with the revenue to justify it | Cost, and low adoption among on-site trades |
| Buildertrend | Quote only (custom) | Residential builders and remodelers | US-focused; weak VAT handling for UK work |
| Simpro / Joblogic | Quote only | Field service and M&E contractors | Lighter on main-contractor project management |
| BuildersAI | Free in beta (early 2026) | Small UK contractors, 3 to 50 staff | Lacks back-office depth (CIS, accounting) |
| Bespoke (ESRE) | One-off build; no per-user fees | Contractors whose workflow spans estimating, delivery and back office | Higher upfront; built in weeks |
Which fits depends on your size and model. A larger contractor gets the depth of Procore. A house builder leans to Buildertrend. A field service or M&E firm goes to Simpro or Joblogic. The smallest firm takes a light tool such as BuildersAI. If no single platform covers estimating, delivery and the back office without running three systems, a bespoke build is the alternative. ESRE's working construction demo opens without a login.
Procore is the dominant platform in construction project management globally, and it holds 4.5/5 on Capterra from 2,665 reviews (checked July 2026). It does not publish pricing; it is quoted on application by company size and module selection. The market says the same thing everywhere. It is expensive. A small contractor usually pays tens of thousands of pounds in the first year, once you add the set-up and the training.
Its depth is real. Document control. RFIs. Drawings, with a record of each version. Job costing, by phase and by category. Subcontractor records. Financial reports. All of them are full. The problem for a smaller firm is not what it can do. It is the cost, which needs an income most smaller firms do not have. Site staff also use it less than they should. Project managers use it; trades and subcontractors use WhatsApp. The system is only as good as the data people put in. A UK site holds workers from several subcontractors. Getting them all to record the same way is hard.
The job costing part draws its own complaints. Reviewers call it very painful when the margin differs from item to item. The system cannot hold an unusual price structure correctly.
Buildertrend is US-based and residentially focused, and rated 4.5/5 on Capterra from 2,486 reviews (checked July 2026). It no longer publishes fixed monthly tiers; pricing is now a custom quote based on builder type and construction volume. The client portal is strong. A client can see how the job is going, approve their choices, and send messages through it. That matters most on house renovation and new-build work, where talking to the client takes a lot of time.
The job costing part has a known fault. It handles VAT badly. Reviewers say it spreads VAT across cost codes at random, so the budget figures cannot be trusted. Some UK contractors have standard-rated and zero-rated work on the same job. That is common on a refurbishment with both homes and commercial space. For them this fault matters.
Note: CoConstruct was acquired by Buildertrend in February 2021 and has received no meaningful feature updates since. Existing CoConstruct users are being migrated to Buildertrend rather than CoConstruct being developed further.
Simpro and Joblogic are field service management platforms that have strong construction-adjacent functionality: job scheduling, asset management, compliance tracking, and invoicing. Both price on custom quotes. They suit contractors who operate a field service model (maintenance contractors, M&E subcontractors, facilities management companies) more than main contractors running complex multi-trade projects. The project management depth (variation orders, programme management, drawing control) is limited compared to Procore or Buildertrend.
Based on how UK SME contractors use project management software in practice, the features that deliver the most value are:

The platforms above sit at the enterprise end. The gap is real. No well-known mid-market product serves a UK smaller firm below £500 a month. Not one that covers job costing, document control and subcontractor compliance without a serious weakness in one of them.
BuildersAI, a UK-developed platform for SME contractors with 3 to 50 employees, was in beta as of early 2026 and free during that phase. It works without a connection, and it holds the programme, the budget and the documents. It has less back office than the older platforms. It does not cover invoicing, CIS, or a link to your accounts.
The gap named above is worth explaining, because it is not an accident. Nobody built the product because nobody could afford to.
A vendor must build the whole thing before it sells one licence. Job costing, document control, CIS, retention, drawings, a client portal. That is years of work, and it must then be paid for by contractors below £500 a month. Only the large end of the market covers that cost, so that is where the products go.
We build the other way round. Every contractor we build for shares one foundation, and that foundation already holds what all of them have in common. A job, a cost line, a subcontract, a document, an audit trail. Each firm pays only for the part that is its own. The sum that used to need a whole market now needs one contractor.
That is why a system of your own now costs less than the rent. We give the figures in what does it cost to own and run your own systems. We explain the foundation in bespoke software for a whole sector.
Some contractors work in a way that is truly their own. A specialist subcontractor with unusual costs. A contractor who needs a client portal in its own name. A business that builds and also sells products, or manages property. No single ready-made platform covers all of what they do. A system of your own makes sense in two cases. The other choice is three separate systems, with somebody moving data between them. Or you need a connection that no standard connector makes. That may be to your own estimating system, to the platform of a client, or to your ERP. A system of your own also has no licence for each user, so it does not cost more as the team grows. We usually build and deliver it in weeks, not months.
You can see this in a working system. The ESRE live construction demo opens with no login, and it shows the work in this guide. Sign in as project manager and see the live task board with Part L evidence, or as client and check progress. It is a working system, not a screenshot.
