Business growth consultant: a manufacturing director’s guide to hiring one

A buyer asks for your best price on 12,000 machined parts a year. Sales sees a new account worth pursuing. Production wants to know whether the parts will run in batches of 1,000 or arrive as fifty urgent call-offs. Finance has a different question. Who pays for the material if the buyer only takes the first batch?

All three are looking at the same enquiry. Until somebody gets those answers, the board doesn't know how much the work is worth, whether it fits, or what it will cost to win.

A business growth consultant helps owners decide where growth should come from and what has to change to achieve it. In a manufacturing or engineering business, that means following a commercial decision far enough to see what happens on the shop floor and in the bank. Sometimes the right outcome is a new market. Sometimes it is a better agreement with a customer who already buys from you.

What does a business growth consultant actually do?

You should be able to name the decision you are buying help with. “Grow sales by 10%” is an ambition. “Decide which two customer groups deserve our only applications engineer's time next quarter” is a brief. It gives the consultant something to investigate and the managing director something to act on.

The work usually has three parts. First, establish what is happening using orders, quotes, job costs and conversations with buyers and staff. Second, put credible options in front of the people who own the decision, with the costs and consequences of each. Third, agree who will put the chosen option into practice and how the business will judge the result. Some engagements stop after the decision. If you expect someone to stay through implementation, price and agree that at the outset.

Take the 12,000-part enquiry. A consultant might sit with the estimator, reconstruct the price at three batch sizes, ask purchasing for the material commitment and join the account manager on a call with the buyer. The deliverable might be one page showing which price and call-off terms the business can accept. That page could be worth more to the owner than a new sales strategy.

Why the manufacturing brief is different

In the Department for Business and Trade’s 2025 survey, 79% of UK manufacturing SME employers aimed to grow sales over the next three years, up from 75% in 2024. Across SME employers as a whole, the proportion held at 71%. At the same time, more manufacturers identified energy prices and late payment as obstacles.

These are survey responses. They tell us about ambitions and pressures, not how many firms achieved growth or how many of the same firms gave both answers. They do suggest a useful opening question for a board meeting. If the order book grew by the amount you want, which bill would you have to pay first? Read the government survey and underlying tables.

When is it worth bringing someone in?

One good reason is a disagreement that the business has the evidence to settle. Sales wants another account manager because enquiries are going unanswered. Engineering says it spends Friday afternoons pricing jobs that were never going to be placed. Both could be right. An outside pair of hands can follow a sample of enquiries, speak to the buyers and put a value on the time being lost.

A second reason is a decision that would be expensive to reverse. Before funding a second shift, find out how much of the forward demand is covered by purchase orders, how much is a forecast and which work needs the same few skilled people. Ask what happens to the case for recruitment if the largest customer's next release slips a month.

There are also cases where the owner already knows what needs doing. If quotes are ready on time but sit in a shared inbox awaiting the owner's signature, run a two-week trial with a delegated approval limit. You may get the answer before you've finished interviewing consultants.

Which kind of help fits the problem?

One person may cover two of these roles. What matters is whether the proposal says who will do Monday morning's work. A workshop on account management and a day spent calling lapsed buyers with your sales manager are different purchases.

Where should the consultant look first?

At Fox Healey & Co we use six areas to frame the investigation. An owner can use the same questions before speaking to anyone.

Start small. Pick a repeat order, a lost quote and a job that everyone remembers being difficult. Ask sales, production and finance to walk through each one together. Three jobs cannot establish a pattern, but they can show which records to pull for a proper test. Often the most revealing moment comes when the estimator and the production supervisor use the same word, “setup”, to mean different amounts of work.

There is a local example of why this matters. Abbey Group in Knowsley had invested in processes including laser cutting, fabrication and CNC machining. As its capabilities expanded, so did the demands on programming, quoting and scheduling. Made Smarter's account describes how Abbey brought factory machines and commercial planning together through a material requirements planning system. The case documents a change in how the business worked. It gives no basis for assigning a sales uplift to a consultant. Read Made Smarter’s Abbey Group case study.

A worked example: which order would you want more of?

Imagine a precision engineering firm with one fully booked finishing cell. Two prospective orders can use it. The customer names and numbers below are illustrative. Both orders can be delivered and both customers are equally likely to pay.

Order A brings in £900 more contribution in total. Order B earns £30 more for every hour on the operation that limits output. Choosing B frees 50 hours. To beat A, the business must earn more than £900 from those 50 hours, or more than £18 per freed hour on average. If those hours stand idle, A earns more. If there is suitable work waiting, B may be the better order. This is why the sales director needs the production planner in the conversation.

The customer relationship can still change the decision. A housing order might protect a family of profitable repeat parts. The bracket buyer might need an expensive initial approval before issuing a second order. Ask the consultant to show those assumptions separately so you can see which part of the recommendation rests on judgement. Read more on customer profitability in manufacturing.

How much should a business growth consultant cost?

The most useful comparison is what it will cost you to reach a decision and put it into practice. A day rate tells you little if one proposal includes buyer interviews, job costing and a trial while another allows for two meetings and a report. Request a price for the first defined piece of work. Ask for the number of days, expenses, internal staff time and the price of any implementation support to be shown separately.

A fixed fee suits a bounded question, such as deciding which of three sectors to pursue. A day rate can suit a short investigation where the state of the records is uncertain. Agree a spending limit and a review date. A retainer can make sense when someone will work alongside the team for several months. Specify what happens between meetings and how the arrangement ends.

A fee test you can do on a calculator. Suppose the fee is £6,000 and the implementation requires £2,000 of extra internal or external cost. At a 25% incremental contribution margin, the business needs £32,000 in additional sales to recover the £8,000. At 15% it needs roughly £53,333.

These are break-even examples, not UK fee benchmarks. Allow for capacity, the time it takes to collect the cash and any extra fixed costs. If the benefit is less scrap or fewer paid overtime hours, measure the cost actually avoided instead.

An owner can reasonably ask what happens if the investigation concludes the opportunity is too small. An engagement that gives you a sound reason to avoid a poor investment has done its job. The contract should let you stop there.

What should the first 90 days produce?

Here is a possible brief for a business whose estimates take too long and whose sales team suspects it is losing repeat work. The dates are suggested review points. A business selling capital equipment on a year-long cycle will need longer to see orders land.

Take care with the results. If the trial group contains more repeat buyers than the earlier group, an improved win rate may simply reflect the mix. Count revisions once. Compare quotes issued in equivalent periods and give customers enough time to decide. Keep open quotes visible. For a long sales cycle, an earlier technical approval is useful evidence of progress, even while the eventual order remains uncertain.

For the open opportunities that sit outside the trial, see how to assess the quality of a sales pipeline.

Research on management practices offers some perspective. In an experimental study of British manufacturing businesses using 2015 data, the ONS found that a 0.1 increase in its management score was associated with 6.7% higher labour productivity after adjusting for characteristics including size and industry. The study could not establish causality. There is no credible way to turn that figure into a forecast return on a particular adviser. Read the ONS analysis and methodology.

How do you choose a business growth consultant?

Give each shortlisted consultant the same brief. An anonymised example of a recent order is a better starting point than an hour of presentations. Here are five questions worth asking across the table.

1. What would you need to see before recommending anything? Listen for specifics. Someone reviewing quote performance should want dates, values and outcomes, but also a conversation with the person doing the estimating.
2. Which assumption would you test first? A credible answer might be that late quotes are costing you orders. The next sentence should tell you how the consultant would establish whether buyers agree.
3. Can you show me a comparable decision you helped a client make? Ask what the client did, what changed and over what period. A relevant reference can matter more than an impressive logo.
4. Who does the work on both sides? Establish who will interview customers, reconcile the figures, approve changes and brief the team. If it all falls to your busiest engineer, cost that time into the proposal.
5. What do we keep when you leave? The price model, definitions, decision log and working files should be usable by the people who inherit them. Agree access, confidentiality and ownership before sharing customer data.

Ask one final question if the fee depends on results. How will you separate the consultant's effect from a price rise already agreed, a customer returning after a shutdown or a large order the sales team had won before the project started? Agree the baseline and exclusions while everyone still has the same interest in getting them right.

A brief you can take to the first meeting

Write down the decision in a sentence. Add the date by which it must be made, the person who owns it, the records available and the one constraint the adviser must respect. Then finish this sentence: “We will know this work was worth paying for when we can…”

For the opening enquiry, that might read: “By the next buyer meeting, we need three costed batch options and a view of how much material we can fund. The commercial director will agree release quantities with the buyer. Finance will sign off the maximum exposure before we reserve capacity.”

That is a growth brief people can actually work to. It gives the buyer a better quotation, the planner a credible production requirement and the owner a decision they can defend. For businesses facing a similar gap between orders and cash, our DT&G Engineering working-capital article takes that question further.
