Key takeaways
A strong business case for paid social is a small, capped test, not a big ask. Show the goal, what a customer is worth, the most you can pay per enquiry, the proven organic content you will advertise, a three-month budget with a cap, how results will be tracked and the result that would mean stop. Keep organic in the plan.
- Ask for a capped 3-month test, not an open budget.
- Show affordable cost per enquiry from customer value.
- Name the proven organic content you will advertise.
- Agree in advance what result means stop.

Chat on WhatsApp →What should a paid social business case include?
A business case should be one page with the numbers a director needs.
- Goal and deadline.
- Customer value and affordable cost per enquiry.
- Proven organic content to advertise.
- Three-month budget with a cap.
- How results will be tracked.
- Stop, change or scale criteria.
Why propose a test rather than a budget?
A capped test limits risk and makes the decision easy to approve. Meta's budget tools let you set a lifetime cap so spending cannot exceed the agreed figure. A clear end date and success criteria turn a debate into an experiment.
How do you show it can pay back?
Work back from customer value to the cost per enquiry you can afford, then show organic evidence that the content brings enquiries. Explain that the first weeks are learning time. Track results as GA4 key events or platform conversions and check against your own records.
- Payback time: when organic and paid social earn it back
- Organic vs paid cost per lead: comparing like with like

Chat on WhatsApp →How do you keep organic in the case?
Explain that paid will amplify proven organic content and that organic keeps the profile credible for people who click ads. The IPA's research supports combining brand building with activation. Cutting organic to fund ads usually makes ads more expensive.
What objections should you prepare for?
Prepare for 'we tried ads before', 'organic is free' and 'how do we know it worked'. Answer with what will be different this time, the real cost of organic time and the tracking plan.
What does this look like in practice?
A pattern we see: a marketing manager's request for an ongoing ad budget was turned down twice. A one-page proposal for a £1,200 capped three-month test, behind two posts that had already brought enquiries, with a stop rule at £80 per enquiry, was approved in one meeting.

Frequently asked questions
How do I convince my boss to spend on social media ads?
Propose a small, capped test rather than an open budget. Show what a customer is worth, the most you can afford per enquiry, the proven organic content you will advertise, how you will track results and what result would mean stopping. Directors approve limited, measurable risks more readily.
How much should I ask for in a paid social test?
Enough to learn: for many UK small businesses, about £300 to £500 a month on one platform for three months. Set it as a capped lifetime budget. Asking for a modest, fixed amount with clear success criteria is usually easier to approve than a large ongoing budget.
What if the test does not work?
Agree in advance what you will change, such as creative, offer or audience, and when you will stop. A failed test still teaches you something about your audience and content. Keep organic running so the business does not depend on the test's outcome.
