Introduction: The First Big Decision After Choosing ERP
You've recognized the warning signs that you've outgrown spreadsheets. You've compared ERP vs CRM vs accounting software and decided ERP is right for your business. You've even researched what ERP actually is and chosen a system.
Now comes the decision that will significantly impact your budget, operational flexibility, and long-term success: Cloud (hosted) or On-Premise (self-hosted)?
This decision affects:
- Upfront investment (LKR 500K vs LKR 5M difference)
- Monthly costs (predictable vs variable)
- Internet dependency (critical in Sri Lanka)
- Data control (where sensitive data lives)
- Scalability (how easily you grow)
- Customization (how much you can tailor)
The software vendors will push you toward their preferred model (usually cloud, because it generates recurring revenue). But what's actually right for YOUR business, YOUR infrastructure, and YOUR budget in Sri Lanka?
This guide cuts through the sales pitches and gives you the facts.
☁️ What is Cloud ERP? (The "Netflix" Model)
Think of cloud ERP like Netflix. You don't install Netflix on a local server in your office—you just open your browser, log in, and stream. Cloud ERP works the same way.
How Cloud ERP Works:
- Vendor hosts everything: ERP provider runs software on their servers
- You access via internet: Employees use web browser or mobile app
- No local installation: Nothing installed on office computers
- Subscription pricing: Pay monthly/yearly per user
- Automatic updates: New features applied automatically
✅ Cloud Advantages:
- Low upfront cost (no servers)
- Predictable monthly expenses
- No IT infrastructure needed
- Access from anywhere
- Automatic updates
- Faster implementation
- Easy scalability
❌ Cloud Drawbacks:
- Internet dependency (critical in SL)
- Ongoing costs forever
- Less customization
- Data location concerns
- Vendor lock-in
- Privacy considerations
🖥️ What is On-Premise ERP? (The "Own Your Infrastructure" Model)
On-premise is the traditional model. Think of it like owning DVDs instead of subscribing to Netflix—you own the content, you control the player, everything runs in your house (or office).
How On-Premise Works:
- You buy software license: One-time purchase/perpetual license
- You buy/lease servers: Physical servers in your office
- You install software: IT team installs ERP on your servers
- You manage everything: Backups, updates, security
- You own infrastructure: Servers, data, installation
✅ On-Premise Advantages:
- No internet dependency
- Full control over data
- One-time cost (mostly)
- Deep customization possible
- No vendor lock-in (data)
- Complete privacy
- Lower long-term cost
❌ On-Premise Drawbacks:
- High upfront cost (LKR 5-10M)
- IT expertise required
- Hardware management burden
- Backup responsibility
- Manual updates (complexity)
- Limited remote access
- Scaling requires hardware
