This is where fundraising becomes a real business lesson. Revenue is the money that comes in. Profit is what remains once you have paid for what it took to earn it. When a teenager can see that difference, they start making stronger choices about pricing, reinvesting, events and the next idea.
Give every pound a clear category
Keep the record simple enough to use. Create separate lines for income from services, products, events, support and grants. Create separate lines for materials, printing, travel, packaging, venue costs and any other direct expense. Do not worry about business jargon; the habit of recording clearly is the point.
For physical cash, agree a routine with a parent or guardian. Count it together after an event, write down the amount and store it safely. A clear routine protects the relationship as well as the money.
Learn the difference between a good sale and a good business decision
Suppose you sell ten handmade items for £50. It sounds like a £50 success until you remember £22 of materials and £5 of packaging. The true profit is £23. That does not mean the idea was bad; it means you can now decide whether to increase the price, reduce costs, buy materials more carefully or choose a different product.
That is the Expedition Treasurer mindset: look at the complete picture before deciding what to do next.
Treat receipts as information, not clutter
A receipt tells you what something really cost. Take a photo or put the receipt in one named envelope, then add the amount to your record as soon as you can. At the weekly check-in, compare receipts to the original plan. Were the materials more expensive than expected? Did an extra cost appear? The answer improves the next job.
Keep personal family spending separate from fundraising spending wherever possible. If an adult pays for something, agree whether it is a gift, a loan to be repaid from profit or a cost that belongs in the business record.
Make a weekly money meeting feel useful
Fifteen minutes is enough. Look at what came in, what went out, what is safely set aside and what decision is next. A teen should be able to explain the numbers; the adult should help with safety, questions and bigger decisions. This is not about taking over. It is about building confidence through a regular, calm routine.
Worked example: a car-wash morning
A Saturday car-wash session brings in £96 from eight cars. The team used £12 of shampoo, £4 of cloths and £6 of poster printing, so the true profit is £74. At the weekly review they notice that two customers asked about a monthly slot. Before buying more supplies, they decide to test a monthly booking option with those customers. The record has turned a busy morning into a decision about repeat income.
The five-line money review
Common mistakes that cost time or money
- Celebrating sales total without subtracting materials and other costs.
- Mixing cash from an event with household money.
- Throwing away receipts before the weekly review.
- Using a vague “miscellaneous” line instead of explaining the cost.
- Spending the next week’s working money before checking whether it is needed.
Do this this week
- Create one shared income-and-cost record.
- Choose a physical or digital receipt routine.
- Agree cash-handling boundaries with a parent or guardian.
- Record the next fundraising activity before it happens.
- Hold a 15-minute review at the end of the week.
- Choose one decision from the numbers, not from guesswork.
