Hiring an estimator vs installing estimating software
Sooner or later every growing firm has the same conversation: the owner cannot keep pricing everything, so do we hire an estimator or put in software? Both can work. Both can be an expensive mistake. The right answer depends on your quote volume, your job complexity, and what problem you are actually trying to solve.
First, name the actual problem
"We need an estimator" usually means one of three different things. One: quotes go out too slowly and jobs are being lost to faster rivals. Two: the owner is drowning and the firm cannot grow past their working week. Three: pricing is inconsistent, some jobs make money, some quietly lose it, and nobody knows which until the end. These are three different problems, and the estimator-versus-software question lands differently for each.
Speed and owner-time problems are mostly processing problems: measurement, assembly, formatting, chasing rates. Consistency problems are mostly knowledge problems: rates and rules living in one person's head. Be honest about which one is costing you money, because you are about to spend real money fixing it. If it helps, our piece on scaling past the owner's head covers how to separate judgement work from processing work.
What a full-time estimator really costs
As a rule of thumb, a competent estimator in most UK regions is advertised somewhere between 35,000 and 55,000 pounds a year, more in London and for commercial experience. Add employer's NI, pension, holiday cover, a desk, software licences and recruitment, and the realistic all-in figure is often half as much again. That is before the risk column: notice periods, sick weeks, the possibility they leave after eighteen months and take the knowledge with them.
None of that makes hiring wrong. A good estimator brings things no tool does: they visit sites, read a client, smell a problem drawing, negotiate with subcontractors and carry relationships. If your work is complex, bespoke or heavily subcontracted, that human layer is the value, not the typing.
What estimating software actually covers
Modern estimating software does the processing layer: it turns a job description or a set of drawings into measured quantities, prices them from a rate book, and assembles the documents. QS Quoter, to use the example we know best, produces a full bill of quantities at your own rates through a structured, reviewable path from measure to send, with a client-facing copy and a private copy showing your costs, and every line editable before anything goes out.
What software does not do is walk a site, charm a client, or negotiate a subcontract package. It also does not remove the need for judgement: someone senior still sets the rates and reviews the output. The honest framing is that software is a processing engine with your knowledge inside it, not a replacement estimator. If a vendor claims otherwise, read our piece on what AI estimating software actually does and does not do before signing anything.
| Factor | Full-time estimator | Estimating software |
|---|---|---|
| Annual cost | Salary plus on-costs, commonly 45,000 to 75,000 GBP all-in | Subscription; installed systems from 2,000 to 10,000 GBP onboarding |
| Workflow | Delegated to a professional estimator | Software-assisted draft with human review |
| Consistency | Good, but varies by person and mood | Same rates applied the same way every time |
| Site visits and client reading | Yes | No, that stays with your team |
| Complex one-off packages | Strong | Needs human review and editing |
| Walks out the door | Can | Rate book stays yours |
| Capacity ceiling | One person's week | Scales with volume |
The third option: an installed system with support
There is a middle path that suits firms past the DIY stage: having an estimating system installed and configured inside the business rather than just buying a login. AGMM does this for commercial clients. The process is a discovery call to map how you price now, a written business case with the numbers, the install itself, then a pilot where the system runs alongside your existing process until the output has earned trust. Onboarding is scoped between 2,000 and 10,000 GBP depending on the size of the job, plus 10 percent of the tracked value the system creates, which keeps the incentive on results. Details are on the commercial page.
The reason this middle path exists is that most software failures in trade firms are adoption failures, not product failures. Somebody has to load your real rates, fit the tool to your workflow, and hold the team's hand for the first month. If nobody owns that, the licence becomes shelfware.
How to decide this month
- Count your quotes. How many went out last quarter, and how many enquiries died unquoted? The dead ones are the cost of the current setup.
- Time one quote honestly. Site visit to send, elapsed days and owner-hours.
- Classify your work. Repeatable domestic jobs, or bespoke one-offs?
- Run the cheap experiment first. Software costs days to trial; a hire costs a year to unwind. Try the tool on your next three real quotes, compare the output against what you would have sent, then decide whether a hire is still needed on top.
The blunt summary
Hire a person for judgement you lack. Install a system for processing you are drowning in. Most growing firms under about ten staff are drowning in processing, which is why the software route usually comes first and the estimator hire, when it happens, arrives later and does a better job standing on top of a system. Whichever way you go, the goal is the same: quotes out fast, priced consistently, without the owner's evenings as the raw material.
