Most decisions in a small business are made in the dark. Hire or not? Raise prices or not? Open on Sunday? Buy more supplies? Run a campaign now or in a month? Without numbers, any of these decisions is guesswork dressed as instinct. And when guesswork fails, it costs - money that doesn't come back and months to fix the mistake.
Good news: you already have the data you need. Every booking you accepted, every checkout you closed, every service you delivered, is recorded. What's missing is the habit of looking - 15 minutes a week, week after week. Here's the complete system to turn data into decisions.
The 4 metrics worth 80%
There are literally dozens of metrics you can track. Most don't help - noise. Focus on these 4. If you look at them once a week, you'll know more about your business than 90% of professionals.
Each metric answers a different question about your business. Revenue = is money coming in? Occupancy = is your calendar being used? Average booking value = is what you sell valued? Retention = do clients come back? When any of them drops, you know exactly where to investigate.
1. Revenue: where the money goes
Look at revenue in three windows: day (spot drops), week (see trends) and month (year-over-year). Each window tells a different story.
- Daily: serves to detect surprises. If a Wednesday dropped 50% and the rest is normal, it was a fluke (holiday, bad weather, local event). Don't draw conclusions.
- Weekly: the most useful view. Patterns emerge - which days fill, which stay empty, what's the normal weekly curve.
- Monthly: only compare against the same month of the previous year. Comparing July with June says nothing (seasonality); July-2026 vs July-2025 says everything.
2. Occupancy: the metric nobody sees and should
Occupancy is the percentage of your weekly slots filled with bookings. If you work 40 hours a week and only 24 of those have clients, your occupancy is 60%. The other 40% is paid (or at least available) time without return.
Healthy thresholds:
- Below 50%: you have lots of idle capacity. Focus on filling (campaigns, reactivation, marketing).
- 50-70%: healthy, room to grow with small actions.
- 70-85%: ideal. You have flow but with some space for reschedules and urgent clients.
- Above 85%: overcrowded. Risks: fatigue, errors, lack of buffer. Consider hiring or raising prices.
3. Average booking value: growth without more clients
Average booking value = total revenue ÷ number of completed bookings. It's the most underrated metric in small business management. Raising the booking value is often more profitable than winning new clients - same client, more value per visit.
Ways to raise the booking value:
- Sell product at end of service: client who buys product lifts booking value by 20-40%.
- Suggest complementary service: cut + beard, manicure + gel polish, massage + foot scrub.
- Premium tier of same service: classic cut €18 vs premium cut €25 (with wash included).
- Pre-paid pack: 5 sessions with 10% off paid upfront.
In Reports > Revenue > by service, you see which services pull the booking value up and which take time without much margin. Those that take time without margin are candidates to redesign (change duration, change price, include product).
4. Retention: the real thermometer of your business
If 80% of clients return within 90 days, you're doing something right. If only 40%, there's a problem - in service quality, in follow-up, or with competition. Retention is the naked truth about your client experience, no filters.
How to measure in BookHero: in Clients, sort by last visit. Count how many have last visit > 90 days ago and divide by total. For example: 100 active clients in last year history, 35 with last visit > 90 days = 90-day retention is 65%.
- Above 80%: excellent. Your clients are fans.
- 60-80%: healthy, always room to improve.
- 40-60%: yellow alert. Investigate where the relationship breaks.
- Below 40%: red alert. Some pillar (quality, communication, price) is misaligned.
The 15-minute weekly routine
Just having the numbers isn't enough - you need to look at them regularly. Ideal routine is 15 minutes Sunday evening or Monday morning. Always the same moment, week after week. Here's the checklist:
Weekly revenue vs previous week
In Reports > Revenue > Weekly. Up, flat, or down? If down by more than 10%, note and investigate during the week.
Next week's occupancy
Look at the calendar. How many empty slots? If more than 30% empty 7 days out, consider a quick reactivation campaign.
Month-to-date average booking value
Total month revenue ÷ completed bookings. Compare with previous month. Up? Flat? Reflects what you're doing.
New inactive clients
In Clients, sort by last visit. Who crossed into >90 days inactive this week? Add to next month's reactivation list.
Notes for next week
1-2 concrete actions based on what you saw. E.g., promote Tuesday slots, contact 5 inactives, suggest product to Saturday clients.
Alarm signals: when to act now
- Weekly revenue drops more than 20% vs 4-week average: investigate (competition? failed campaign? unforeseen seasonality?).
- Average booking value drops more than 10% with no clear reason: you're selling cheaper (unplanned discounts) or fewer extras.
- 90-day retention drops below 50%: systemic experience problem. Call 5 clients who didn't return.
- Occupancy above 90% for 4 weeks straight: overload, consider hiring or raising prices.
- Same weekday with <30% occupancy for 8 weeks: that day probably should close (or have reduced hours).
How to cross-reference data to find opportunities
Looking at each metric in isolation gives sense; cross-referencing reveals opportunities. Practical examples of cross-references worth gold:
| Cross | Question it answers | Typical action |
|---|---|---|
| Revenue per staff × avg booking value | Who sells more and who sells more value? | Training for those with low booking value |
| Occupancy per day × revenue per day | Are there full days with low booking value? | Raise price only on peak days |
| Retention × service type | Which services bring clients back? | Promote high-retention services |
| Top 20% clients × frequency | Do top clients come back regularly? | Special program for the top |
The monthly close: the complete ritual
On the last business day of the month, dedicate 30-45 minutes to a complete monthly close. It's not the same as the weekly routine - it's deeper. Note in a notebook or simple sheet:
- Total month revenue.
- Comparison vs same month previous year (% up or down).
- Revenue per staff (for commissions payroll).
- Top 10 clients by spend - send thank-you note to top 3.
- List of inactive clients to reactivate next month.
- 1-3 decisions to make based on this data (price adjustment, campaign, hire).
Frequently asked questions
Do I really have to do this every week?
Yes. Looking at numbers once a month leaves you 4 weeks behind. 15 minutes a week is the most profitable investment you'll make in your business. Put it on the calendar as a fixed commitment.
I'm not good with numbers, is this for me?
Especially for you. Reports don't require math - they're clear charts and lists. The skill you build is noticing patterns, and that's learned in a few weeks just by looking regularly.
What retention rate is good?
Above 70% at 90 days is strong for most services. Above 80% is excellent. But it depends on service type. Hairdressers have naturally higher retention (~85%) than personal trainers (~60%) or tattoo artists (~30%). Compare with yourself, month over month.
What if I see data but don't know what to do with it?
That's fine - the first month is about learning to look. From the second on, you'll start having ideas automatically. If there are numbers you don't understand, ask us - help@bookhero.app replies in hours.
Worth exporting reports to Excel?
For complex ad-hoc analysis, yes. For weekly routine, no - just look inside BookHero. Export only when you want to cross with external data (costs, VAT, etc.) or for accounting.
