Most SME owners underprice. Not because they do not know what their costs are, but because they set prices defensively — based on what they think customers will accept, what competitors charge, or simply what they charged last year plus a bit.
This article explains how to build a pricing decision from first principles: cost floor, market position, value delivered, and the psychology of price anchoring. It is not about charging as much as possible — it is about charging what is correct given the value you deliver.
Start with your cost floor — not your competitor's price
Before you look at what anyone else charges, you need to know the minimum price at which selling your product or service makes commercial sense. That floor is:
Minimum viable price = Total unit cost ÷ (1 − Target gross margin %)
If your total unit cost is £28 and you need a 40% gross margin, your minimum price is £28 ÷ 0.60 = £46.67. Selling below this — regardless of what competitors charge — is loss-making at the gross level.
This sounds obvious. But a surprising number of businesses set prices by starting with the competitor rate and working backwards, never checking whether that price actually covers their costs at the required margin.
Know your total unit cost — not just your purchase price
For product businesses, the cost floor is only valid if it reflects your true landed cost. That means purchase price, freight, duty, port handling, customs clearance, packaging, and the cost of any returns or quality allowance. For service businesses, it means your true delivery cost including the time of everyone involved, not just the most senior person billing.
Undercosting is the most common cause of underpricing, and it is usually invisible until margins have been eroding for months.

Position against the market — but do not anchor to it
Competitor pricing tells you what the market currently believes value is worth — but it does not have to define your price. If you match the market average, you are implicitly saying your offer is average. If you want to charge above market, you need to be able to answer one question clearly: Why would a customer pay more for what we offer?
If you cannot answer that question in two sentences, you are not ready to price above the market. If you can, your job is to make sure that answer is front and centre in every piece of sales communication.
The three pricing signals that erode trust
Pricing is not just arithmetic — it is communication. The way you present a price tells customers something about your confidence in your offer. Three patterns consistently undermine credibility:
- Immediately discounting from your stated price. If you drop 20% the moment anyone pushes back, you have told them your real price was always lower. They will always push back now.
- Odd psychological pricing on B2B products. £4,997 instead of £5,000 works in consumer retail. In B2B, it reads as evasive. Round numbers project confidence.
- Pricing that varies too widely by customer. If two customers compare notes and find a 40% difference for the same service, you have a credibility problem and a client relationship risk.
How to test a price increase without full commitment
The safest way to test a higher price is on new customers only. Leave your existing customer base at their current rates and apply the new pricing to all new enquiries for 60 days. Measure your conversion rate. If it does not materially change, your market will bear the higher price. If conversion drops significantly, you have data — not just an assumption — to work with.
The compounding effect of small price increases
A 5% price increase on £400k revenue adds £20k to gross profit with no increase in costs, volume, or headcount. Applied over three years with no compounding, that is £60k. With compounding, it is more. Most SME owners spend enormous energy trying to grow revenue by 20% when a 5% price increase on existing products would deliver equivalent or better margin improvement with a fraction of the effort.
Rule of thumb: On a 35% gross margin business, a 3% price increase has the same gross profit impact as an 8.5% increase in volume. You need to sell significantly more to match the effect of pricing correctly.
Document your pricing decisions
Pricing decisions made verbally, without documentation, drift. Six months later no one remembers why a particular price was set, whether the cost basis has changed, or when it was last reviewed. A one-page pricing record — cost floor, market benchmark, positioning rationale, review date — takes 20 minutes to create and saves hours of confusion later.
