Twenty Suppliers, Ninety Minutes: A Practical Margin Review for UK SMEs

Sales forecasts and payroll usually receive management attention because they are visible. Purchasing often does not. A subscription renews quietly, an energy contract rolls over, a professional services retainer continues because the work is useful, and a logistics rate rises with a surcharge that nobody challenges. For businesses turning over between £1m and £10m, the cumulative effect can be several percentage points of margin.

The review below is designed to be completed in 90 minutes. It does not require a procurement team. It requires a list, a calendar and a willingness to ask three or four uncomfortable questions.

Minutes 0–15: list the top 20 suppliers by spend

Start with the bank statements and the purchase ledger, not with the supplier database. Identify the 20 suppliers that account for the largest annual spend. Include utilities, software, professional services, logistics, facilities, telecoms, insurance and any regular contractor. For each, record the annual spend, the contract owner, the renewal date, the notice period and whether the contract auto-renews.

This step often reveals that spend is more concentrated than expected. It is common for five suppliers to account for 60% to 70% of third-party spend. Those are the relationships where a small change in rate or terms has a disproportionate effect.

Minutes 15–30: calculate spend under management

Spend under management is the proportion of total third-party spend that is covered by a known contract, a named owner and a diary date for renewal. If the answer is below 60%, the business is buying by accident. The remainder is spend that renews without review, is paid against outdated rates or is duplicated across departments.

For each of the top 20, mark the contract as active, rolling, expired or informal. An expired contract is not necessarily a problem, but it usually means the original terms no longer reflect the relationship. An informal arrangement with a long-standing supplier may be comfortable, but it is difficult to benchmark.

Minutes 30–45: map renewal dates and notice periods

Put every renewal date and notice period into a single calendar. The notice period matters more than the renewal date. A contract that renews on 31 March may require notice by 31 December. Missing that date can lock in another year at the old rate.

Flag any renewal falling within the next 120 days. Those are the immediate negotiation opportunities. For each, identify the person who will make the call and the information they need: current spend, usage, benchmark rate, alternative quotes and the business outcome if the contract is not renewed.

Minutes 45–60: test the top five for rate, usage and duplication

Take the five largest suppliers and ask three questions. First, has the rate changed since the contract began, and by how much relative to the relevant index? Second, is the business using the volume or service level it is paying for? Third, is the same service being bought elsewhere under a different name?

Software is a frequent offender. A customer relationship management platform may be licensed for 40 users when only 25 log in regularly. An energy contract may include a capacity charge based on outdated assumptions. A logistics contract may include surcharges that were introduced during a period of high fuel costs and never removed. The review is not about squeezing suppliers; it is about paying for what the business actually needs.

Minutes 60–75: rank the opportunities

Rank each opportunity by annual saving and effort. A £12,000 saving on a software renewal that requires one email is more valuable than a £4,000 saving on a facilities contract that requires a tender. For a £3m business, a 2% reduction in third-party spend is £20,000 to £30,000 depending on the cost base. That is often more than a modest price increase on the sales side would deliver.

Minutes 75–90: agree the negotiation plan

Assign an owner and a deadline to each of the top three opportunities. Prepare a one-page brief for each negotiation: current spend, benchmark, desired outcome, walk-away position and the internal approval required. The plan should be specific enough that someone can make the call without further preparation.

Three quick-win negotiation scripts

1. Energy renewal. 'We are reviewing our contract before the renewal date. Our current rate is X pence per kWh, and we have usage data for the last 12 months. Can you confirm your best fixed rate for a 12-month term, and whether the standing charge can be reduced? We are also obtaining a comparison quote, so please include any loyalty or multi-site discount.'

2. Software subscription. 'We are reviewing our licence count ahead of renewal. Our usage report shows 25 active users against 40 licensed seats. We would like to move to a 25-seat plan or agree a reduced rate for the unused seats. Can you confirm the price for that configuration and whether the renewal date can be aligned with our financial year?'

3. Professional services and logistics. For professional services: 'We value the work, but the retainer has increased by 8% without a change in scope. Can we agree a fixed fee for the next 12 months, with a clear list of included deliverables and a review at six months?' For logistics: 'Our volumes have changed since the contract started. Can you re-rate the fixed charges and confirm which surcharges are still applicable? We would like a benchmark against our current cost per pallet before we commit to the next term.'

Make the review repeatable

The first 90-minute review will expose more than the business can action at once. That is normal. The value comes from making it a quarterly routine: update the top 20, check the next 120 days of renewals, and review one category in detail. Over a year, the business moves from buying by accident to buying with a plan.
