EngineerOffice Pricing Explained (2026): Real Costs for UK Field Service Firms

EngineerOffice has no public price list you can add up in five minutes. It is sold by BQE Software on a per-user, per-month basis, normally billed annually in US dollars, with different rates by user type and separate modules for things like accounting and CRM. So the honest answer to "how much does EngineerOffice cost" is: whatever your quote says, plus implementation, plus currency and card costs, plus the module you did not realise was extra.

There is a bigger point, though, and nobody ranking for this term makes it. EngineerOffice is a practice management tool for engineering consultancies. It exists to track time against projects and turn billable hours into invoices. If you run vans, issue certificates and get called out at 4pm on a Friday to a dead chiller, you are looking at the wrong category of software, and no amount of price comparison will fix that. This piece prices EngineerOffice honestly, converts it into a real annual cost in pounds, then gives you a two-minute test so you know which shortlist you should actually be building.

What EngineerOffice actually is (and who makes it)

EngineerOffice comes from BQE Software, a US vendor whose product family also includes ArchiOffice for architecture practices and the newer CORE suite. The design brief for all of them is the same: time and expense capture, project and phase tracking, work in progress, accounts receivable, and billing that survives an audit by a client's quantity surveyor.

That is genuinely useful software for a structural, civil or M&E design consultancy billing on hourly rates and stage fees. It is not field service management. There is no engineer job board, no reactive callout scheduling, no asset register per site.

One thing to know before you make contact: BQE's own website now leads with CORE rather than EngineerOffice, so a request for EngineerOffice pricing today will usually come back as a CORE quote. If you are searching "engineers office" hoping to find something that gets job sheets off paper, that is a sign you are in professional services territory rather than trades territory.

EngineerOffice and BQE CORE pricing structure

The model, rather than the numbers, is what matters here. BQE publishes indicative pricing on its own pricing page, and you should treat that as your live source rather than any figure quoted in a blog post, including this one. What to expect structurally:

• Per user, per month, billed annually. Monthly rolling terms, where offered, cost more.
• Tiered user types. A full professional seat, a cheaper time-and-expense-only seat, and read-only access are priced differently. The headline "from" figure is almost always the cheapest seat, not the one your project managers need.
• Modules, not one flat product. BQE promotes a pay-for-what-you-need approach, so time and billing, project management, accounting, CRM and forecasting can be separate lines on the invoice.
• Minimum user counts and annual commitment. Ask what the floor is, because a five-seat minimum changes the maths for a small office.

When you ask for a quote, ask for it itemised by user type and module, in writing, with the contract term stated. A single blended monthly figure is not a quote, it is a headline.

What's included vs what costs extra

For practice management software generally, the first-year invoice is rarely the same shape as the pricing page. Line items to explicitly confirm before you sign:

• Core seat licences, split by user type
• Accounting or general ledger module
• CRM and opportunity tracking
• Forecasting and resource planning
• Mobile time entry app access
• Data migration from your current system or spreadsheets
• Onboarding, configuration and chart-of-accounts setup
• Training days, per session or per head
• Premium or priority support tiers
• API access and any integration development
• Custom invoice templates and bespoke report writing

Implementation is usually the largest first-year cost with software of this type, and it is almost never on the pricing page. Get it quoted as a fixed fee with a defined scope, not as an open-ended day rate.

The true annual cost in GBP for a UK firm

Here is the build-up for a hypothetical 12-engineer, 2-office-staff contractor. Do not take my multipliers as your quote. Take the structure, and fill in your own figures.

| Cost line | How to work it out | Your figure | |---|---|---| | Full seats | Office staff, owner, anyone raising invoices | | | Time-entry seats | 12 engineers, if they enter time at all | | | Modules | Accounting, CRM, forecasting as quoted | | | Annual commitment | Multiply monthly by 12, not by 10 | | | Currency cost | USD list price converted, plus fees | | | VAT position | Reverse charge on imported services | | | Implementation | Fixed fee, first year only | | | Training | Days x rate x heads | | | The gap | Whatever you still pay for site paperwork | |

Three lines deserve explanation.

Currency. If you are billed in dollars on a card, you pay the conversion rate plus a non-sterling transaction fee, which MoneySavingExpert puts at around 3% with typical UK cards. On a five-figure annual subscription that is a real line, and your renewal price moves with the exchange rate whether the vendor raises prices or not.

VAT. Buying services from an overseas supplier means accounting for VAT yourself under the reverse charge rules set out in HMRC's VAT Notice 741A. Recoverable for most contractors, but worth confirming with your accountant rather than assuming.

The gap. This is the line people forget. If the software cannot produce a fire alarm service record or an EICR on a phone, you are still running paper, Word templates or a second app alongside it. Price that honestly, including the admin hours spent chasing and retyping.

Then divide the whole lot by 12 engineers and by 12 months. Cost per engineer per month, all in, is the only number worth comparing.

The field service gap: what EngineerOffice does not do

Specifically, and not as criticism, because it was never built for this:

• No engineer-facing job board with travel, on-site and complete status
• No drag-and-drop scheduling for reactive callouts alongside planned maintenance
• No dynamic mobile forms for fire alarm service records under BS 5839, EICRs under the private rented sector electrical safety regulations, F-Gas logs or gas certificates issued by Gas Safe registered engineers
• No offline-first app that keeps working in a basement plant room on one bar
• No asset history per site, so nobody can see what happened to that AHU last November
• No photos tied to the job record
• No parts or van stock

A design consultancy proves its work with a drawing and a timesheet. You prove yours with a signed certificate, a photo and a date. Different problem, different software.

EngineerOffice vs field service platforms: how the pricing models differ

| | Practice management (EngineerOffice, CORE) | Field service platform | |---|---|---| | Pricing unit | Per licensed user, by user type | Per engineer or per van, admin seats often cheap or free | | Minimum term | Annual commitment typical | Monthly or annual, varies widely | | Setup fee | Paid implementation is the norm | Increasingly none, but always ask | | Modules | Accounting, CRM, forecasting priced separately | Core job management usually bundled | | Mobile app | Time and expense entry | Full job execution on site | | Offline working | Rarely a design goal | Essential, verify it in a real basement | | Certificates | Not applicable | Sometimes included, sometimes an add-on |

Verify every row in writing. And be aware that older field service contracts can combine the worst of both worlds: multi-year lock-ins, paid modules and an engineer app that nobody opens. That is not a category problem, it is a specific-product problem, and it is why you test with real engineers before you sign.

The 5-question fit test: are you buying the right category?

1. Do you bill clients by the hour against a project, or by the job and the maintenance contract?
2. Does getting paid depend on issuing a compliant certificate?
3. Do your people work from a van or a desk?
4. Do you need planned maintenance schedules against assets at customer sites?
5. Does anyone need to complete work with no mobile signal?

Mostly project and office answers: EngineerOffice or CORE is a legitimate shortlist entry, price it properly. Mostly van and certificate answers: you are in field service management, and you should be pricing that category instead. Three or more van answers and you can close the EngineerOffice tab now.

Alternatives worth pricing alongside it

• BQE CORE is the successor product and what you will most likely be quoted. Per user, per month, modular.
• A generic project tool plus Xero or QuickBooks covers a lot of ground for a small consultancy at a fraction of the cost. Both publish their prices.
• Simpro serves larger UK contractors and quotes on request rather than publishing prices.
• Commusoft and Joblogic both publish tiered per-user pricing for UK trades.
• Klipboard, which now includes BigChange, sits at the enterprise end on a quoted basis.
• Engineer OS is built for independent UK firms running 5 to 30 engineers in fire and security, electrical and M&E, HVAC, plumbing and gas, with mobile forms, certificates and photos in the core product rather than sold as modules.

How to get a quote you can actually compare

Ask for pricing in GBP if the vendor will do it, itemised by user type, with setup and migration stated as separate lines. Get the contract term, the renewal uplift clause and the data export terms in writing before you talk about discounts, because those three clauses decide what year three costs.

Then insist on a trial that uses your own certificate template and two real engineers on their own phones, in a real plant room. Not a demo. Finally, build a three-year total cost sheet rather than a monthly figure, and include the cost of whatever you will still be running alongside it.

The verdict: for an engineering consultancy billing hours against projects, EngineerOffice pricing can represent fair value, and the implementation cost buys you a properly configured billing engine. For a 12-van contractor whose revenue depends on certificates leaving site the same day, it is money spent on the wrong problem, however good the discount.

FAQ

How much does EngineerOffice cost per user? BQE prices per user per month, usually billed annually, with different rates for full professional seats, time-and-expense-only seats and read-only access. Any published starting figure reflects the cheapest seat type. Check the current BQE pricing page and ask for a written quote itemised by user type and module.

Is EngineerOffice the same as BQE CORE? No, but they come from the same vendor. EngineerOffice is the older practice management product for engineering firms, alongside ArchiOffice for architects. CORE is the newer cloud suite that BQE now leads with, so most EngineerOffice enquiries are answered with a CORE quote.

Does EngineerOffice have a free trial or a free version? There is no free tier. BQE offers demos and guided trials through its website rather than open self-service sign-up, and a useful trial normally needs configuration and a sales conversation first.

Is EngineerOffice suitable for a UK field service or maintenance company? Generally not. It handles time, projects, WIP and billing for consulting work. It does not provide reactive callout scheduling, PPM schedules against site assets, dynamic mobile certificates, offline working, job photos or van stock, which is the day-to-day reality of a van-based contractor.

What are the hidden costs of engineering practice management software? Implementation and configuration, data migration, training days, extra modules such as accounting or CRM, premium support tiers, integration work, custom invoice and report templates, currency conversion and card fees on USD billing (typically around 3% on top of the exchange rate, per MoneySavingExpert), and the cost of the paper or second app you still run for site paperwork.

What is the best alternative to EngineerOffice for a firm with 5 to 30 engineers? A field service platform rather than a practice management tool. Commusoft and Joblogic publish their pricing, Simpro and Klipboard quote on request, and Engineer OS is built specifically for independent UK firms in that 5 to 30 engineer range that want mobile forms, certificates and photos included as standard.
