Illustrative two-week test
From a first conversation to one paid customer.
A product photographer wants to sell a small package: five finished images of one item, one minor revision round, delivered within five working days for $250. The buyer supplies the item. All details and numbers in this example are hypothetical; they are not a reported client result or recommended market price.
Customer and route: local makers preparing an online product listing. At a market, the photographer has spoken with 12 suitable owners who agreed to receive the package details. This test uses those conversations, not an assumed audience of everyone with a shop.
First approach: “You mentioned needing images for the new item. Here is the five-photo package we discussed, with a sample, timing and what is included. Would that fit the listing, or do you need a different kind of image?” Answer questions, confirm scope with interested buyers and follow up only as agreed.
Limit: allow six hours and $60 of acquisition expense across the two weeks, excluding the cost of fulfilling any purchased job. Record the time as well as money. A small test is useful only if the business can afford its downside.
12 details sent
Record each agreed contact, the offer sent and the date. Do not count the same person again as a new prospect when following up.
Four replies; two suitable jobs
One reply asks for lifestyle photography outside this offer; one needs work later. Two buyers have a matching job and receive a confirmed scope and price.
One paid purchase
One buyer purchases. The other has not decided. A quote, a compliment and an unpaid expression of interest are not additional customers.
What did the sale leave? The $250 order has $95 of variable fulfilment costs, leaving $155 toward acquisition, fixed overhead and profit. Subtract the $60 acquisition expense: $95 remains before overhead and acquisition time. Valuing the six acquisition hours at $25 would add $150 of time cost, leaving a negative $55 on that comparison. Cash expenditure and the value of your time are different measures; show both. Do not count hoped-for repeat purchases as money already earned.
What changes next? The photographer has evidence that one buyer accepted this offer, not a proven scalable channel. Review why the second buyer paused and whether the same route can reach more suitable people at less effort. If nobody replies, check contact delivery and relevance. If replies show a different need, adjust the offer or customer choice. If people buy but the work loses money, change the economics before repeating it.
Keep a simple record: source, contact date, buyer need, reply, next step, quoted amount, paid order, fulfilment cost, acquisition expense and time. The SBA’s marketing guidance recommends setting a sales approach, budget and review process. This example adds the actual arithmetic and distinguishes early evidence from a guarantee.
