From $15K/Month to $45K/Month: The VietHawaii Case Study

They were paying DoorDash 30% of every order. Now they keep 97% and tripled their volume. Here's exactly how we did it.

The Problem: Death by a Thousand Cuts

When VietHawaii came to us, they were bleeding money in ways they didn't even realize.

The Visible Problems:

  • 2+ hours/day on phone orders

  • Constant order errors

  • Maxed out on phone capacity

  • Losing to competitors with online ordering


The Hidden Problems (the real killers):
  • DoorDash taking 30% of every order

  • Uber Eats taking 30% of every order

  • No customer data (platforms own it)

  • No way to market to past customers

  • Reputation controlled by algorithms


Let me show you how insane the math was:

Monthly online orders (via apps): 600
Average order value: $35
Monthly revenue: $21,000
Platform fees (30%): $6,300

They were paying $6,300/MONTH just for someone else to process their orders.

That's $75,600/year. Gone. To companies that don't care if they succeed or fail.

The Solution: Own Your Customers

We built VietHawaii a custom ordering system. Their own. Forever.

For Customers:


  • Full menu with photos

  • Easy customization

  • Save favorite orders

  • Real-time status updates

  • Scheduled ordering


For the Restaurant:


  • Orders print directly to kitchen

  • Zero phone time

  • Complete order accuracy

  • Full customer database

  • Marketing capabilities


The Investment:


  • Custom system: $18,000

  • Monthly costs: $20 hosting + 2.9% payment processing

  • No subscription fees. No commission. They own it.


The Results: 300% Revenue Increase

Online Order Volume

Before: 15-20 orders/day via third-party apps
After: 60-80 orders/day via their own system

That's a 300% increase in online order volume.

Same food. Same location. Same staff. Just removed the friction and kept the profits.

Phone Time Eliminated

Before: 2+ hours/day taking phone orders
After: 10-15 minutes/day for edge cases

That's 1.75 hours/day × $15/hour × 365 days = $9,581/year in labor savings

Plus: Staff now focused on food quality and customer experience instead of answering phones.

Platform Fees Eliminated

Before: $6,300/month to DoorDash/Uber Eats
After: ~$600/month in payment processing (2.9%)

Monthly savings: $5,700
Annual savings: $68,400

The system paid for itself in less than 4 months just on fee savings.

Order Accuracy

Before: 5-10 wrong orders per week (phone miscommunication)
After: Zero wrong orders

Each wrong order costs ~$15 in remakes + angry customers.

That's $3,900-7,800/year in hidden costs. Eliminated.

The Real Numbers: Total Impact

Monthly Revenue Before: $15,000
Monthly Revenue After: $45,000

Monthly Costs Before: $6,300 (platform fees) + $1,500 (labor on phones)
Monthly Costs After: $600 (processing) + minimal labor

Monthly Profit Increase: ~$36,000

Investment: $18,000
Payback Period: 15 days (yes, days)

The 5 Features That Made the Difference

1. Mobile-First Design

85% of orders came from phones. We designed for thumbs, not mice. Big buttons. Easy scrolling. Zero friction.

2. One-Page Checkout

Name. Phone. Payment. Done.

No account creation required. No endless forms. Under 60 seconds from menu to confirmed order.

3. Kitchen Integration

Orders appear on a kitchen display. Clear formatting. Station routing. No ticket confusion.

4. SMS Updates

"Order received" → "Being prepared" → "Ready for pickup"

Customers know exactly when to arrive. No crowded lobby. No "is my order ready?" calls.

5. Repeat Order Button

"Order Again" shows your last 5 orders. One tap to reorder your usual.

60% of their orders are now repeat customers using this feature.

The Owner's Take

"I was paying DoorDash $6,300 every month for the privilege of having them own my customers. Now I keep that money, I own my customer data, and I'm doing 3x the volume. The system paid for itself before I even finished paying for it."

Why This Matters for YOUR Business

VietHawaii isn't special. They're a local restaurant doing good food with limited resources.

What made the difference:

  • Eliminating platform fees (you're paying 30% for what?)

  • Owning customer relationships (your data, your marketing)

  • Removing friction (every click costs customers)

  • Automation (phones don't scale, systems do)


This works for:
  • Restaurants

  • Service businesses

  • Retail

  • Anyone giving 30% to middlemen


The Question You Should Be Asking

How much are you paying in:

  • Platform commissions?

  • Phone labor?

  • Order errors?

  • Lost customers due to friction?


Add it up. I bet it's more than $18,000/year.

Which means a custom system pays for itself in Year One and prints money every year after.

Let's run the numbers for YOUR business.

I'll calculate exactly what you're losing, exactly what a system would cost, and exactly when you'd break even.

If it doesn't make sense, I'll tell you. But I've never had it not make sense for a business doing 50+ orders per day.

The question isn't whether you can afford to do this.

It's whether you can afford not to.
