Website Building Requirements: Small Business Checklist

Website building requirements are the plain-English scope for what the site must do, what pages it needs, what features it needs, who will maintain it, and how everyone will know the build is finished.

The short answer: define the job of the site before choosing a platform or hiring a builder. A lead-generation site, portfolio, ecommerce store, content hub, and custom workflow do not need the same requirements. If you skip that distinction, every later decision turns into a tiny argument wearing a hoodie.

Website building requirements checklist

Direct answer

A useful website requirements document should answer seven questions:

1. What job does the site need to perform?
2. Which pages and page types are required at launch?
3. Which features are mandatory, optional, or explicitly out of scope?
4. Which systems must connect to the site?
5. Who will update content after launch?
6. How will the client or owner accept the finished work?
7. What ongoing costs and maintenance tasks are expected?

The internal builder-selection guide says to start with the real site job: local lead generation, portfolio and brand presentation, ecommerce and checkout, content and SEO, or a custom workflow that may outgrow simple builders. The contract guide says to list pages, features, integrations, CMS, responsive behavior, third-party services, acceptance criteria, milestones, change control, IP/licensing, maintenance, and support. The cost comparison guidance adds a practical warning: the real bill includes domains, storage, bandwidth, booking features, paid apps, plugins, transaction needs, and time.

What to put in the builder or agency brief

A strong brief does not need to be fancy. It needs to be specific.

Include:

• Business type and audience.
• Primary conversion goal.
• Required pages and page templates.
• Required features and integrations.
• Content owner and image owner.
• Examples of sites you like, with reasons.
• Accessibility and mobile expectations.
• SEO requirements for URLs, metadata, and internal links.
• Launch deadline and review milestones.
• Maintenance expectations after launch.
• Out-of-scope items.

The phrase “build me a website” is not a requirement. It is a trapdoor. A requirement says what should exist, how it should behave, and how it will be approved.

Common mistakes to avoid

• Choosing Wix, Squarespace, WordPress, Shopify, or Webflow before defining the site job.
• Listing pages but not features.
• Asking for “SEO” without specifying editable metadata, URLs, content structure, and internal links.
• Forgetting who owns copy, images, approvals, and post-launch updates.
• Treating apps, plugins, domains, storage, booking tools, and maintenance as invisible costs.
• Launching without acceptance criteria for forms, mobile pages, analytics, redirects, and content review.
• Leaving change requests informal, then acting surprised when the scope grows tentacles.

FAQ

What are website building requirements?

Website building requirements define the pages, features, integrations, content responsibilities, design expectations, acceptance criteria, timeline, maintenance plan, and budget assumptions for a website project.

Do I need requirements for a small website?

Yes. A simple one-page brief can prevent missed pages, unclear form behavior, surprise app costs, and vague approval standards. Small sites still need scope.

What should a website requirements document include?

Include the site goal, required pages, must-have features, integrations, CMS needs, mobile expectations, SEO basics, timeline, acceptance criteria, change-control process, and maintenance owner.

Should requirements come before choosing a website builder?

Yes. Choose the builder after the requirements. A portfolio site, ecommerce store, booking site, and content hub need different tradeoffs.

How detailed should acceptance criteria be?

Detailed enough that both sides can tell whether the work is done. Examples include approved pages, tested forms, working analytics, mobile review, redirects, and launch checklist completion.
