When to Choose SaaS

Standard Needs

Your requirements match what's available — CRM, email marketing, accounting, project management.

Immediate Start

You need to be operational today, not in 4 weeks.

Limited Budget

Predictable monthly costs matter more than long-term savings.

When to Build Custom

Unique Process

Your business workflow can't fit into off-the-shelf tools without significant workarounds.

Competitive Advantage

Technology IS your differentiator — you need features competitors don't have.

Data Sovereignty

You need full ownership and control of your data for compliance or strategic reasons.
