Part 2: ROI Analysis for Small Businesses
Calculating Return on Investment
Formula:
ROI = (Revenue Gained - Cost) / Cost × 100
Example:
Revenue gained: $24,000/year
App cost: $1,000
ROI = ($24,000 - $1,000) / $1,000 = 2,300%
Real ROI Examples
Restaurant Ordering App:
Costs:
- AppStruct: $900/year
- Domain: $12/year
- Total: $912
Revenue Impact:
Before: 100% orders through DoorDash (30% commission)
Monthly sales: $20,000
Commission paid: $6,000/month = $72,000/year
After: 40% through own app (0% commission)
Own app sales: $8,000/month × 0% = $0 commission
DoorDash sales: $12,000/month × 30% = $3,600/month
Annual savings: $28,800 in commissions
ROI: ($28,800 - $912) / $912 = 3,059%
Salon Booking App:
Costs:
- AppStruct: $540/year
- Total: $540
Time Savings:
Before: 3 hours/day on phone bookings
3 hours × $25/hour × 260 days = $19,500 value
After: 30 minutes/day managing app
2.5 hours saved × $25/hour × 260 days = $16,250 value
Plus: 25% more bookings (optimized scheduling)
10 extra bookings/month × $75 avg = $750/month = $9,000/year
Total value: $25,250
ROI: ($25,250 - $540) / $540 = 4,576%
Retail Inventory App:
Costs:
- AppStruct: $900/year
- Total: $900
Impact:
Before: 15% lost sales (stockouts) + 20% over-ordering (waste)
Annual impact: -$18,000
After: Real-time inventory management
Stockouts reduced: 15% → 3%
Over-ordering reduced: 20% → 5%
Annual impact: -$3,600
Savings: $14,400
ROI: ($14,400 - $900) / $900 = 1,400%

Part 9: Common Mistakes Small Businesses Make
Mistake 1: Building Too Complex Too Soon

- Takes 3 months to build
- Never launches
- Gets abandoned
✅ Right:
- Start with core 3-5 features
- Launch in 2-3 weeks
- Add features based on real usage
- Iterate monthly
Example: Salon owner wanted booking, CRM, inventory, marketing automation, employee scheduling. Built booking only first. Launched in 1 week. Added other features over next 6 months based on actual needs.
Mistake 2: Not Testing with Real Customers
❌ Wrong:
- Build entire app alone
- Launch without testing
- Discover customers confused
- Scramble to fix
✅ Right:
- Test with 5-10 customers before launch
- Watch them use it (don't guide)
- Fix confusing elements
- Launch with confidence
Mistake 3: Ignoring Mobile Experience
❌ Wrong:
- Design for desktop only
- Assume customers use computers
- Mobile version is afterthought
✅ Right:
- Design mobile-first (most customers on phones)
- Test on actual phones
- Optimize for touch
- Fast loading on mobile data
Reality: 70-90% of small business app usage is on mobile.
Mistake 4: No Marketing Plan
❌ Wrong:
- "Build it and they will come"
- Launch and wait
- Wonder why nobody uses it
✅ Right:
- Plan marketing before launch
- Email announcement to customers
- In-store signage and staff training
- Social media promotion
- Incentives to try (discount on first app order)
Mistake 5: Choosing Wrong Monetization
❌ Wrong:
- Charge customers to download (for service businesses)
- Too expensive for market
- Complicated pricing
✅ Right:
- Free for customers to use (you benefit from efficiency)
- Or simple pricing ($1-2 fee vs commission to competitors)
- Clear value proposition
Example: Restaurant ordering app should be FREE for customers (you save on commissions). Salon booking should be FREE (you reduce no-shows).
