10 Questions to Ask Before Buying Any SaaS for Sale


If you're exploring the world of SaaS acquisitions, a great place to begin is Sitefy’s curated marketplace of SaaS businesses for sale: https://sitefy.co/product-category/saas-businesses-for-sale/
— a clean, focused platform where you can browse real, revenue-generating SaaS products without noise.

Buying a SaaS can be one of the smartest moves you make—but only if you go in with the right questions. The truth is, most problems in a SaaS business aren’t obvious from the listing alone. You uncover them by asking thoughtful, strategic questions that reveal how the business actually works behind the scenes.

Below are the 10 questions every buyer should ask before making any offer.

  1. Why Are You Selling the SaaS?

This is the single most important question, because motivations expose risks.

Healthy reasons:

New project or startup

Time constraints

Burnout

Lack of marketing ability

Red flags:

Revenue declining

Mounting support complaints

Competitors overtaking them

Look beyond the words—listen for hesitation or vagueness.

  1. What Is the Current MRR Trend Over the Last 12 Months?

MRR alone is not enough; the trend tells the real story.

Ask for:

Month-by-month revenue

Spikes or declines

Seasonal patterns

A stable or rising trend is a strong indicator of product-market fit.

  1. What Is the SaaS’s Churn Rate?

Churn is the silent killer of SaaS businesses.

You need to know:

How many users cancel monthly

Why they cancel

What patterns exist in cancellation behavior

High churn means you’ll constantly fight to stay above water.

  1. Where Do Customers Come From?

A SaaS without reliable acquisition channels is a risky buy.

Clarify:

SEO / organic traffic

Paid ads

Social/communities

Integrations or referrals

Word of mouth

Repeatable acquisition = sustainable growth.

  1. How Much Time Does This SaaS Require Weekly?

Support and maintenance vary wildly from product to product.

Ask:

What tasks they do weekly

What tasks they do monthly

The average number of support tickets

How much is automated vs manual

This helps you match the SaaS to your lifestyle and schedule.

  1. Can You Walk Me Through the Codebase and Tech Stack?

Even if you're not technical, you need an overview.

Get clarity on:

Languages/frameworks used

Documentation quality

Tech debt

Integrations that may break

Hosting or infrastructure costs

If needed, hire a developer to audit things before closing the deal.

  1. What Are the Biggest Challenges You’ve Faced Recently?

A good founder will openly share what’s not working.

Examples include:

Bugs that need fixing

Slow-moving features

Problems with growth

Customer complaints

Pricing challenges

This gives you a realistic picture of the road ahead.

  1. Are There Any One-Time Revenue Sources Included in the MRR?

Some SaaS listings inflate the numbers.

Confirm:

True recurring revenue vs one-time sales

Setup fees

Consulting income

Custom work

Make sure the MRR is real recurring revenue.

  1. Is the Revenue Concentrated With a Few Customers?

If 20–40% of revenue comes from one client, losing them could sink the business.

Ask for:

Revenue distribution

Customer size and type

Renewal patterns

You want broad, diversified revenue—not dependency.

  1. What’s Included in the Sale?

Never assume anything.

Clarify:

Domain

Codebase

Customer database

Integrations

Documentation

Email lists

Social accounts

Branding assets

Knowledge transfer

Transition period support

A clean, complete transfer prevents future headaches.

Final Thoughts: Smart Questions Lead to Smart Acquisitions

Buying a SaaS isn’t about finding the cheapest deal or the flashiest dashboard—it’s about understanding the inner workings of the business. When you ask the right questions, you uncover hidden risks, validate strengths, and set yourself up for long-term success.

The best SaaS acquisitions happen when buyers dig deep, think logically, and choose opportunities aligned with their skills and goals.
