The Free Workshop That Ate the Week
Elena runs a small accounting practice in Burgas with 2 employees. She wants to grow by attracting small e-commerce clients. Her idea is to run free monthly workshops on VAT and invoicing for online sellers, then convert attendees into paying clients. She has run two workshops so far. Each took her about 20 hours to prepare and promote, cost BGN 300 in venue and materials, and drew 12 and 15 attendees. From 27 attendees she has gained 2 clients worth BGN 600 a month each in recurring fees. Her billable hourly rate is BGN 80, and she had to turn down about 10 billable hours to prepare each workshop. She is now considering running them twice a month and paying BGN 500 per event for targeted social media advertising.
1. Calculate whether the workshop model is currently profitable and identify the hidden cost.

Value Elena's time at her opportunity cost. Each workshop takes 20 hours at BGN 80, which is BGN 1,600 of foregone billable work, plus BGN 300 direct cost, so the true cost per workshop is about BGN 1,900. Two workshops cost roughly BGN 3,800. The return is 2 clients at BGN 600 a month, or BGN 1,200 recurring monthly revenue. On a one-month view the model looks like a loss, but the clients are recurring, so the payback period matters. If each client stays 12 months, the two clients are worth BGN 14,400 of revenue, which comfortably exceeds BGN 3,800, before accounting for the cost of serving them. So the model is not unprofitable; it has a long payback and a conversion rate of 2 out of 27, about 7.4%. The hidden cost is Elena's time, which is invisible in the BGN 300 cash figure and is the largest cost. The real question is whether the conversion rate and client lifetime value justify scaling.
2. Evaluate the proposal to double frequency and add BGN 500 of advertising per event.

Doubling frequency doubles both cost and output only if the conversion rate holds. With advertising, cost per workshop rises from about BGN 1,900 to about BGN 2,400 including the BGN 500 ad spend. If attendance rises, say to 25 per event, and conversion stays at 7.4%, that is about 1.85 new clients per event, or BGN 1,110 of new monthly recurring revenue per event. At two events a month, that is BGN 2,220 of new recurring revenue monthly against BGN 4,800 of monthly cost, so cash goes out before it comes back, and Elena must fund the gap from reserves. The risk is that conversion falls as audiences grow colder, and that Elena's 20 hours per event becomes unsustainable at twice the frequency. A better approach is to test the advertising on one event, measure attendance and conversion, and only then decide. She should also reduce preparation time by reusing materials and recording a version, which lowers the opportunity cost per event.
3. Recommend how Elena should redesign the growth idea to protect her billable capacity.

The constraint is Elena's time, not the idea. She should decouple preparation from delivery: build the workshop once, record it, and reuse slides so preparation drops from 20 hours to perhaps 5. She could have an employee deliver or co-deliver, which converts her BGN 80 hourly cost into a lower internal cost. She should qualify attendees before the event, for example with a short registration form asking about turnover and current accounting setup, so the audience is warmer and conversion rises. She should add a paid follow-up consultation, which both filters serious prospects and generates immediate revenue. Finally, she should set a clear test: run three events with advertising and measure cost per acquired client against the BGN 600 monthly fee and expected client lifetime. If cost per client exceeds a few months of fees, the model should be changed or dropped. The principle is to test small, measure conversion and payback, and only scale what the numbers support.
