The real cost of an unclear brief

Most disagreements between small firms and their consultants are not caused by bad work. They are caused by two reasonable people believing they agreed the same thing. A client says "we need more leads" and pictures a full campaign with landing pages and follow-up emails. You hear the same words and price a strategy document with a priorities list. Neither reading is wrong, which is exactly why it becomes expensive.

You can usually spot the warning signs early. Revision rounds that never quite close. Emails becoming shorter and more formal. Questions about invoices that were previously waved through. In a business with tight cash flow, a single disputed invoice can knock a quarter sideways. Sorting expectations at the start is not bureaucracy — it is the cheapest risk management available to a small firm.

Agree the outcome before you discuss the activity

Begin every engagement by getting the client's goal in the client's own words. Ask what success looks like in 90 days, how it will be measured, and who inside the business has the authority to sign things off. Then write those answers down and read them back. If the client hesitates, you have found the gap early, when it is still free to fix.

Turn broad ambitions into testable criteria. Instead of "improve our marketing", agree "three named deliverables by 14 March, plus a monthly one-page report covering enquiries, conversion rate and cost per enquiry". Useful specifics include:

• Deliverables: what is handed over, in what format, and by when.
• Acceptance criteria: what "done" looks like, so sign-off is not a matter of taste.
• Out of scope: an explicit list. This protects you and reassures the client that nothing important has been forgotten.
• Dependencies: what you need from them — access, data, approvals, a named contact — and by when.
• Response times: how quickly each side will reply to questions and approve work.

Put it in writing, in plain English

A short, readable statement of work will serve you better than forty pages nobody opens. Cover the commercial essentials clearly: scope, deliverables, milestones, fees, expenses, payment terms, VAT treatment, notice period, confidentiality, and who owns the intellectual property and at what point. If you work on a retainer, state the monthly scope, what happens to unused time, when the arrangement is reviewed, and how either side can end it.

Payment terms deserve particular attention. Fourteen days is reasonable for a small supplier; thirty is common. If invoices slip, the Late Payment of Commercial Debts (Interest) Act 1998 gives you a statutory right to interest, but it is far easier to agree a deposit up front and staged payments against milestones than to chase later. Keep the language plain enough that both parties could explain the deal to a colleague in two minutes. If they cannot, it is not clear enough.

Build in regular reviews

Projects drift quietly. A twenty-minute call each week for active work, or once a month for a retainer, catches most problems while they are still small. Use the same agenda every time so nobody has to prepare from scratch:

• Progress against the agreed milestones.
• Blockers, and who is clearing them.
• Decisions needed, with a date attached.
• Budget and time used against the plan.
• Risks, flagged with a simple red, amber or green status.

Follow up in writing within a day: three bullets, decisions taken, actions with owners and dates. That short note becomes your audit trail, and it quietly removes the "I thought you were doing that" conversation from the relationship.

Handle changes without friction

Change is normal, so give it a route. Any request that falls outside the agreed scope gets a one-page change note: what is being asked for, the effect on cost and timescale, and what moves if it is added. Set a threshold — say, work under two hours is absorbed as goodwill, anything above is quoted — and apply it consistently. Silently absorbing extra work feels generous for about a fortnight, then it turns into resentment, rushed delivery and a strained relationship. Nobody wins that trade.

Measure success from both sides

Halfway through, and again at the end, ask two questions: did the client get the outcome they wanted, and did you deliver it profitably? Both answers matter. A project that delights the client but loses you money is not a success, and neither is a profitable one that leaves them underwhelmed.

Close the loop properly. Note which assumptions turned out to be wrong, what you would write differently in the next contract, and which parts of the working relationship should be repeated. If the outcome was strong, ask for a testimonial or an introduction while the goodwill is fresh. For longer relationships, hold an annual review of the arrangement itself — scope, rates, and ways of working — rather than waiting for a problem to force the conversation. Clear goals, agreed in writing and checked regularly, are what let both sides measure success and avoid the surprises that cost the most.
