The TRUTH about choosing between Open Source vs SaaS for eCommerce (...this will save you $100,000's in the long run):
Most businesses default to SaaS platforms like Shopify because they're "easier."
Big mistake.
As a team that helps B2B ecommerce sites grow, we've seen this pattern repeatedly. Here's why open source is the clear winner for serious eCommerce businesses:
1️⃣ Total Ownership — With open source, you OWN everything.
Let's break this down:
With SaaS platforms like Shopify or BigCommerce:
- You're essentially renting your store
- Platform changes affect your business without your input
- Migration is expensive and complex if you want to leave
- You're locked into their ecosystem
With Open Source:
- You own the code outright
- Choose any hosting provider
- Select your own development partners
- Freedom to modify anything
- No vendor lock-in
Real-world example: One of our clients needed to integrate their store with a complex ERP system. With Shopify, this would have been impossible. With open source, we built exactly what they needed.
2️⃣ Lower Long-Term Costs
Let's look at the actual numbers for a business doing $1M in annual sales:
SaaS Costs (5-year total):
- Platform fees: $299/month = $17,940
- Transaction fees (2.9%): $145,000
- Basic customizations: $25,000
Total: $187,940
Open Source Costs (5-year total):
- Initial development: $50,000
- Hosting: $6,000
- Maintenance: $36,000
Total: $92,000
That's nearly $96,000 in savings over 5 years!
3️⃣ Unlimited Customization
Here's what you can do with open source that's impossible with SaaS:
- Create custom pricing rules for different customer groups
- Build unique checkout flows
- Integrate with any third-party system
- Modify core functionality
- Create custom shipping calculations
- Design unique product configurations
We recently helped a manufacturer implement complex bulk pricing rules that would have been impossible on Shopify.
4️⃣ Data Control
This is crucial but often overlooked:
With SaaS platforms:
- Your customer data lives on their servers
- They can analyze and monetize your data
- Platform changes can affect your data access
- Migration can be challenging
With Open Source:
- Data stays on your servers
- Complete control over security
- Easy compliance with privacy laws
- Full access to all your data
- Simple backup and migration options
Think about it:
The internet runs on open source (Linux, Apache, MySQL).
These aren't trends. They're battle-tested solutions that have powered business growth for 30+ years.
