How to Budget for a Software Project You Don't Fully Understand

You don't need to be a developer to budget intelligently. Here's how to plan for software costs when the tech is over your head.

How to Budget for a Software Project You Don't Fully Understand

Here's the truth:

You don't need to understand Kubernetes, APIs, or database schemas to budget for a software project.

You just need a framework that protects you from getting burned.

Here's the one I give every non-technical founder:


1. Get 3 estimates and understand why they differ

Don't just collect numbers. Ask each agency:

→ What are you including that others aren't? → What assumptions are you making? → What could cause this to change?

The cheapest bid usually has the most hidden costs.


2. Budget 20-30% contingency for unknowns

Software projects uncover requirements mid-build. Always.

If your estimate is $50K, budget $60-65K. If you don't spend it, great. If you do, you're not scrambling.


3. Break into phases — don't commit the full amount upfront

Phase 1: Discovery and design Phase 2: Core functionality Phase 3: Integrations and polish

This lets you course-correct before you're $100K deep.


4. Budget 15-20% annually for maintenance

A $100K build costs $15-20K/year to maintain.

That includes hosting, security patches, minor updates, and keeping integrations working.

If someone tells you "it's done and you're all set," they're lying.


5. Include discovery as a line item, not overhead

A paid assessment ($3-5K) gives you:

→ A detailed scope → A technical roadmap → Accurate budgeting data → Clarity on what you're actually buying

That $5K saves you $50K in scope creep.


You don't need to know how the engine works.

You just need to know what questions to ask before you buy the car.
