Monthly Financial Review: The 30-Minute Habit
30 minutes a month keeps your business healthy.
A 30-minute monthly review keeps you in control of your business. Check five key numbers, compare to last month and last year, and catch problems before they become crises. The habit is more important than perfection.
Why Monthly Reviews Matter
Most detailers have no idea if they're profitable until tax time. By then, it's too late to fix anything.
A monthly review takes 30 minutes and tells you:
- Are you making money?
- Is the business growing or shrinking?
- Where's the money going?
- What needs to change?
The Five Numbers to Check
1. Total Revenue
All money that came in this month.
- Compare to last month
- Compare to same month last year (if available)
- Trend up, down, or flat?
2. Number of Jobs
Total jobs completed.
- Volume tells a different story than revenue
- Revenue up + jobs down = higher prices (good)
- Revenue down + jobs same = discounting (bad)
3. Average Ticket
Revenue ÷ Number of Jobs = Average Ticket
- This number should grow over time
- Declining average ticket = red flag
- Target: increase 5-10% per year
4. Total Expenses
All money that went out.
- Supplies, insurance, fuel, subscriptions, etc.
- Watch for unexpected increases
- Monthly expenses should be predictable
5. Net Profit
Revenue - Expenses = Net Profit
- This is what you actually made
- Target: 30-50% for solo operators
- 20-35% with employees
The 30-Minute Review Process
MONTHLY REVIEW CHECKLIST (30 min) Minutes 1-5: GATHER □ Pull revenue total from payment processor □ Pull job count from calendar/software □ Export bank/credit card statements Minutes 6-15: CALCULATE □ Total revenue □ Total jobs □ Average ticket (revenue ÷ jobs) □ Total expenses (categorized) □ Net profit (revenue - expenses) Minutes 16-25: COMPARE □ vs. last month (better/worse/same) □ vs. same month last year □ vs. your targets Minutes 26-30: DECIDE □ What's working? Do more of it. □ What's not? Fix or stop. □ One action for next month
What the Numbers Tell You
Revenue Up, Profit Down
You're working more but keeping less. Check expenses — something increased. Or you're underpricing.
Revenue Down, Jobs Same
Average ticket dropped. You're discounting or doing more low-value work.
Revenue Same, Jobs Down
Average ticket increased. You're getting better clients. Good sign.
Everything Down
Business is shrinking. Marketing problem? Seasonal? Competition? Investigate.

The Cost of Not Reviewing
Common Mistakes
→ Revenue means nothing without expenses. A $20K month with $18K expenses is worse than $12K with $4K expenses.
→ Numbers without context are meaningless. Always compare to last month and last year.
→ Five numbers, 30 minutes. Don't build a complex system you won't use.
→ Busy months are when problems hide. Schedule it like an appointment — non-negotiable.
→ A review without decisions is just looking at numbers. End with one specific action.
Schedule a recurring 30-minute calendar block for the 1st of each month: 'Financial Review.' Do your first one this week, even if the month isn't over.
Detaild tracks revenue and job counts automatically. Pull your numbers in seconds instead of digging through records.
Keep a simple notes section in your review: what happened this month? Big jobs, weather issues, marketing changes. Context explains numbers.
Frequently Asked Questions
What if I don't have good records?
Start now. Pull what you can from bank statements and payment processors. It gets easier each month.
Should I use accounting software?
For monthly reviews, a simple spreadsheet works. Software helps with tax prep and detailed tracking.
What about weekly reviews?
Weekly is great if you have time. But monthly is the minimum. Start there and add weekly if it helps.
When should I review with a CPA?
Quarterly is ideal. Monthly reviews are for you; quarterly with a CPA catches bigger issues.
