The first promotion many people run is also the most damaging: 20% off everything, broadcast on Instagram, valid for a week. At first sight it looks attractive - more clients, more visibility, energy. In practice, three bad things happen at once. First: you attract discount hunters who come once and never return. Second: you give 20% off to regular clients who were going to pay full price (direct margin loss). Third: you train your audience to expect regular promotions, and when you don't run them it feels like absence.
Good news: a well-done promotion can bring 30-50 new clients in a month, fill dead hours, and showcase services no one was asking about. Here are the 5 rules that separate promoting well from burning margin.
The math many forget
Simple rule: the discount you give comes out of net margin, not price. Hairdresser charging €30 with €15 margin (50%): 20% off (€6) drops margin to €9. In volume it grows, but net profit can even drop if the new clients don't become regulars. Always have this in mind when designing a promotion.
Rule 1: Promote to a specific audience, not everyone
Universal promotion is a design failure. Every euro of discount must have an identified recipient and clear reason. Here are the 4 audiences where well-done promotion works:
| Audience | Reason | Type of offer |
|---|---|---|
| Inactive clients (>90 days) | Reactivate at low cost | 10-15% or extra service |
| Friends of clients (referral) | Reduce first-visit barrier | 10% or treat |
| Empty slots (Tuesdays, mornings) | Fill dead time | 10-15% only on specific hours |
| Those who never tried new service | Make it known | Promo price 1st visit |
Rule 2: Promote a specific service, not everything
Promoting everything dilutes the signal and maximizes margin damage. Promoting a single service (or specific pair) concentrates attention and protects most of the margin. Strategies that work:
- New service: 1st visit to the new service at special price. Gives it legs to launch.
- High-margin service: promote what has highest margin, not what you sell most. High margin absorbs the discount better.
- Two-service combo: massage + scrub for X. Lifts booking value without direct discount.
- Pre-paid pack: 5 sessions with 10% off paid upfront. Client pays first, keeps coming.
- Dead-hour exclusive: 15% off only on Tuesday 2pm-5pm bookings. Fill time, not the whole calendar.
Rule 3: Short, clear deadline
Always-valid promotion dilutes. Valid 7-14 days creates healthy urgency. The urgency is part of what makes the client decide now instead of postponing (and forgetting).
Always communicate exact end date (until May 31), not vaguely (for limited time). Concrete creates pressure; vague dilutes it.
Rule 4: Personalized communication (not mass)
Mass messaging converts 5-10%. Personalized messaging with name converts 25-40%. Huge difference for 30 extra seconds of work per message.
| Mass (Instagram post) | Personalized (DM/WhatsApp) | |
|---|---|---|
| Promo: 15% off everything! | ✓ Hi [name], 15% off color for you | |
| Typical conversion | 5-10% | 25-40% |
| Effort per message | Almost zero | 30 seconds |
| Margin impact | Hurts everyone | Only those you want to reach |
| Wrong clients reached | Many (hunters) | Almost none |
Rule 5: Measure real return
Promotion without measurement is guesswork. After each campaign, in 3-7 days, calculate:
How many used the promotion
In Bookings or Reports > Revenue, filter by promotion dates. Count how many bookings used the discount.
How many were new clients vs regulars
Cross with the client card. If they were regulars who would pay full, direct loss. If new or reactivated inactives, gain.
Extra revenue vs margin lost
Revenue generated in the campaign minus discounts applied minus direct costs. Compare with same period without promotion.
How many returned in the next 4 weeks
The most important metric. Well-done promotion = at least 30-40% of new clients return within 30 days. Poorly done = <15%.
Decide: repeat, adjust or stop
If margin came out positive and clients return: repeat in similar format. If margin negative or weak retention: adjust segment, deadline or offer type.
Typical mistakes that destroy promotions
- Announcing discount without deadline: client postpones, forgets, never comes.
- Applying discount to all services: dilutes signal, hurts margin.
- Recurring monthly promotion: trains market to always expect promotion.
- Communicating only once: client forgets. Repeat 2-3 times across channels with clear reminder.
- Not preparing capacity: if promotion attracts 20 new bookings and you only have 10 slots, it's chaos.
- Not measuring: campaign ends, you don't know if it worked, repeat the same mistake next time.
Suggested yearly promotion calendar
| Period | Promotion type | Reason |
|---|---|---|
| January | No promotion | Slow month; promotion discounts the little that comes in |
| February | Inactives (15% off) | Reactivate those gone silent |
| March/April | New service (launch price) | Spring energy, openness to novelty |
| May | Mother's Day offers (combo) | Natural occasion, high demand |
| June/July | No promotion | High demand, don't dilute margin |
| September | Back-to-routine (referral push) | Return from holidays, new client profile |
| November | Discreet Black Friday (10%) | Cultural trend, controlled |
| December | Gift voucher (full price) | Voucher = advance revenue |
Frequently asked questions
How many promotions per year are healthy?
3-5 well-designed campaigns annually. More than that trains the market to expect promotions; fewer and you miss natural occasions (Mother's Day, etc.). 1 per quarter is healthy cadence.
Does BookHero have automatic discount codes?
Not yet. Apply discount manually at checkout (direct discount field as value or %). For high-volume campaigns, keep a mental list or simple sheet of who's using the promotion.
Can I run a promotion only for Instagram followers?
Yes, but communicate clearly: exclusive offer for those who follow us on Instagram. And at checkout, they have to prove (show phone). No proof, no discount - otherwise you're giving to those who lie.
Should I do Black Friday?
If you do, do it discreetly. 10% off for 3 days on a specific service. Don't get caught in the retail discount war - your business model is different. Black Friday in services usually is marketing laziness, not strategy.
What if a client demands discount outside promotion?
Firm and friendly response: our rates are the same for all clients throughout the year. During promotion periods, we communicate to those who follow us - if you'd like to keep up, [Instagram link]. Never give in to bargaining. Give in once = give in always.
