Quick Decision Framework
- Build Custom if: unique workflows, M-Pesa/eTIMS needed natively, 20+ users, data ownership critical
- Buy Off-the-Shelf if: standard needs, budget under KSh 300K, need it this week
- Hybrid (recommended): Off-the-shelf for standard (accounting, email) + custom for core operations
- Break-even point: Custom is cheaper after 18-24 months for most Kenyan SMEs
The Big Comparison
| Factor | Custom Software | Off-the-Shelf / SaaS |
|---|---|---|
| Upfront Cost | KSh 500K - 20M+ | KSh 0 - 500K (setup fees) |
| Monthly Cost | KSh 0 (you own it) | KSh 5K - 100K/user/month |
| 5-Year TCO (20 users) | KSh 1.5M - 5M | KSh 3M - 12M+ |
| M-Pesa Integration | Built-in, your Paybill | Through vendor (may charge extra) |
| KRA eTIMS | Native integration | Varies — many don't support it |
| Customization | Unlimited — exactly your workflows | Limited to platform features |
| Data Ownership | 100% yours, on your servers | On vendor's cloud |
| Time to Launch | 2-6 months | 1-2 weeks |
| Scalability | You control architecture | Depends on vendor's pricing tiers |
| Vendor Lock-in | None — you own the code | High — switching costs are brutal |
| Support | Direct developer access | Ticket system, often slow |
5-Year Total Cost of Ownership: Real Numbers
Let's compare a real scenario: A Nairobi wholesale company with 20 staff members needs inventory management, invoicing with M-Pesa, and eTIMS compliance.
Custom Software
- Development: KSh 1,500,000 (one-time)
- Annual maintenance: KSh 150,000/year × 5 = KSh 750,000
- Hosting: KSh 15,000/month × 60 = KSh 900,000
- 5-Year Total: KSh 3,150,000
SaaS Alternative (e.g., Zoho/Odoo)
- Setup/customization: KSh 200,000
- Subscription: KSh 3,000/user/month × 20 users × 60 months = KSh 3,600,000
- M-Pesa add-on: KSh 500/user/month × 20 × 60 = KSh 600,000
- eTIMS integration: KSh 300,000 (custom module)
- 5-Year Total: KSh 4,700,000
Custom saves KSh 1,550,000 (33%) over 5 years — and you own it forever.

When to Build Custom
Build Custom When:
- Your processes are unique: Your billing, inventory, or workflow doesn't fit standard software
- M-Pesa is core: You need deep M-Pesa integration with your own Paybill, automatic reconciliation, and real-time callbacks
- eTIMS/EFRIS/EFD compliance: Off-the-shelf often doesn't support East African tax systems natively
- You have 20+ users: SaaS per-user pricing makes custom cheaper
- Data sensitivity: Healthcare, fintech, government — you need full data control
- Competitive advantage: The software IS your business (e.g., a logistics platform, a lending app)
- Multi-country: You operate in Kenya, Uganda, and Tanzania with different tax and payment systems
When to Buy Off-the-Shelf
Buy Off-the-Shelf When:
- Standard needs: Accounting (QuickBooks), email (Google Workspace), CRM (HubSpot), HR (BambooHR)
- Tight budget: Under KSh 300,000 with no ability to wait for development
- Speed is critical: You need to be operational within days, not months
- Small team: Under 10 users where SaaS monthly costs stay manageable
- Testing a concept: Use SaaS to validate your idea before investing in custom
- Industry standard: For functions like accounting where regulations define the process
The Kenya Factor: Why It's Different Here
In Western markets, off-the-shelf usually wins. In East Africa, custom often wins. Here's why:
- M-Pesa dominance: Most global SaaS products don't integrate M-Pesa natively. You'll pay extra for plugins that often don't work well
- KRA eTIMS: Kenya's real-time tax invoice system isn't supported by most international SaaS. You'll need expensive custom modules
- Local pricing: Custom development in Kenya costs 60-80% less than in the US/Europe, making custom affordable for SMEs
- Internet reliability: Cloud SaaS requires constant internet. Custom can work offline and sync later
- Multi-currency: Global SaaS often struggles with KES, UGX, TZS — custom handles this natively
The Hybrid Approach (Our Recommendation)
Most successful Kenyan businesses use a hybrid approach:
| Function | Approach | Example |
|---|---|---|
| Accounting | Off-the-shelf | QuickBooks, Sage |
| Email & Collaboration | Off-the-shelf | Google Workspace |
| Core Operations | Custom | Inventory, billing, CRM |
| M-Pesa Billing | Custom | Integrated with your Paybill |
| Customer Portal | Custom | Your brand, your UX |
| Mobile App | Custom | Android app for field staff |

Frequently Asked Questions
For businesses with under 10 employees and standard needs, off-the-shelf is usually better. But once you hit 15-20+ employees or need M-Pesa/eTIMS integration, custom becomes cheaper over 3-5 years. We also offer modular development — start with one core module (KSh 300K-500K) and add more as you grow.
This is a valid concern. We mitigate it by: providing full source code ownership from day one, using mainstream technologies (not obscure frameworks), writing documentation, and offering ongoing maintenance contracts. Even if you switch developers, any competent team can maintain the code. With SaaS, if the vendor shuts down, you lose everything.
Yes. Custom software can integrate with QuickBooks, Sage, Google Workspace, M-Pesa, banks, and any system with an API. This is actually a major advantage — we build exactly the integrations you need, rather than being limited by what a SaaS vendor supports.
