Legal Documents for SaaS Products

SaaS is different from a standard website. You're not just collecting emails — you're running ongoing accounts, charging recurring payments, and giving users access to software that may affect their work or business. The legal requirements reflect that.

Here's what a SaaS product needs.

1. Terms and Conditions (Terms of Service)

Your terms are the contract between you and every user. For SaaS they need to cover more than a basic website.

Essential clauses:

• Subscription terms — billing cycle, renewal, cancellation
• Acceptable use policy — what users can and can't do with your software
• Account termination — when you can suspend or delete an account and what happens to the user's data
• Service availability — uptime expectations (or the lack of any guarantee)
• Limitation of liability — capping your exposure if your software fails
• Intellectual property — you own the software; they own their data
• Changes to the service — your right to modify, deprecate, or discontinue features

2. Privacy Policy

Required the moment you collect any personal data — which for SaaS starts at account creation.

For SaaS specifically, your privacy policy needs to cover:

• Account data (name, email, payment details)
• Usage data (feature usage, session logs, error reports)
• User-generated content stored in your platform
• Third-party integrations (Stripe, analytics, customer support tools)
• Data portability — how users can export their data
• What happens to data when an account is closed

3. Cookie Policy

SaaS products typically use cookies for session management, analytics, and feature tracking. You need a cookie policy and a consent banner for non-essential cookies.

4. Refund Policy

UK law gives consumers a 14-day cancellation right. For SaaS, you need to be explicit about:

• Whether the 14-day period applies to your product
• Whether a refund is available mid-subscription or only at renewal
• How cancellations are processed and when billing stops

Many SaaS businesses offer "cancel anytime, no refund for current period" — that's fine, but it needs to be stated clearly.

5. Data Processing Agreement (DPA)

If any of your users are businesses — and especially if they're EU or UK businesses — they will ask for a DPA before signing up. This is a formal document establishing you as a data processor under GDPR.

B2B SaaS without a DPA will lose enterprise deals.

6. Acceptable Use Policy (AUP)

Sometimes included in terms, sometimes a standalone document. Defines prohibited uses: spam, illegal activity, scraping, abuse of other users. Protects you from liability if a user misuses your platform.

What SaaS businesses most commonly miss

• No account termination clause — if a user abuses your platform and you close their account, they can argue there was no contractual basis
• No data deletion timeline — GDPR requires you to state how long you keep data after account closure
• No DPA — fine until your first enterprise customer asks for one and you lose the deal
• Vague subscription terms — leading to chargebacks when users expect refunds you didn't intend to give
