Inventory Management: Never Run Out Mid-Job
Simple systems prevent expensive problems.
Running out of supplies mid-job is embarrassing and costly. A simple reorder system — knowing your usage rate and setting reorder points — keeps you stocked without tying up money in excess inventory.
The Cost of Running Out
- Time lost: Trip to the store mid-day = 30-60 min gone
- Money lost: Paying retail instead of bulk/wholesale
- Reputation: Looks unprofessional to clients
- Stress: Scrambling instead of working smoothly
What to Track
Core Consumables
CHEMICALS: □ All-purpose cleaner □ Car wash soap □ Glass cleaner □ Interior dressing □ Tire dressing □ Wheel cleaner □ Leather cleaner/conditioner □ Spray wax/sealant SUPPLIES: □ Microfiber towels (by count) □ Applicator pads □ Brushes (replace when worn) □ Clay bars □ Polish/compound OTHER: □ Spray bottles □ Trash bags □ Nitrile gloves
The Reorder System
Step 1: Know Your Usage
Track how much you use per month:
- 1 gallon of APC lasts ~3 weeks
- 20 towels need replacing every 2 months
- Tire dressing lasts ~6 weeks
Step 2: Set Reorder Points
When stock hits a certain level, order more:
APC: Reorder when down to 1/4 gallon Towels: Reorder when 20 or fewer usable Glass cleaner: Reorder at 1 bottle left Tire dressing: Reorder at 1/3 bottle
Step 3: Have Backup
Keep at least 2 weeks of supplies on hand. Orders get delayed; you don't want to wait.
Inventory Check Schedule
Daily (Quick Glance)
End of day: Anything critically low for tomorrow?
Weekly (Full Check)
Sunday planning: Go through your list. What's at or below reorder point?
Monthly (Audit)
Full count. What's expiring? What's not moving? What's overstocked?
Buying Smart
Bulk/Concentrate
Pro-grade chemicals are concentrated. One gallon makes 5-20 gallons ready-to-use. Much cheaper than retail spray bottles.
Consistent Suppliers
Pick 2-3 suppliers and stick with them:
- Lower shipping with combined orders
- Possible volume discounts
- Consistent product quality
Don't Overbuy
Cash tied up in inventory is cash not in your pocket. Buy 1-2 months ahead, not 6 months.
Storage and Organization
- Label everything: Dilution ratios, purchase date
- First in, first out: Use older stock first
- Designated spots: Everything has a home
- Climate control: Some products degrade in heat/cold
Inventory Costs
Common Mistakes
→ You can't reorder at the right time if you don't know how fast you go through things. Track it.
→ Set reorder points before you're empty. Account for shipping time.
→ Emergency purchases are expensive. Plan ahead and buy wholesale.
→ Too much inventory ties up cash. 1-2 months ahead is plenty.
→ Weekly inventory check should be part of your Sunday planning.

Keep a 'reorder list' running in your phone. When you notice something getting low during the day, add it immediately.
Frequently Asked Questions
How much inventory should I carry in my vehicle?
Enough for 2-3 full details plus backups of critical items. Restock daily or every few days from home base.
Where should I buy supplies?
Detailing suppliers (P&S, Chemical Guys, Detail Garage) for chemicals. The Rag Company for towels. Amazon/local for general supplies.
What about towel management?
Track towel count by type. Replace worn towels regularly. A towel that could scratch paint is worse than no towel.
Should I use a spreadsheet?
Simple system is fine. A notes app list works. Spreadsheet is better if you want to track costs over time.
