Website Requirements Checklist for Businesses: 50 Decisions to Make Before Development Starts
A good website is easier to build when the important decisions are made before design and development begin. This checklist helps businesses define what the website must achieve, which pages and features are required, what systems must connect, how SEO and accessibility should be handled, who owns the accounts and what support is expected after launch.
Project brief vs requirements checklist: what is the difference?
A website project brief explains the business context: why the website is being built, who it is for, what the business wants to achieve and what constraints exist.
A requirements checklist goes one level deeper. It converts the brief into decisions developers can scope: pages, user actions, content types, forms, ecommerce, integrations, CMS, search requirements, accessibility, analytics, hosting, ownership and support.
Before the checklist: classify every requirement
Without it, the site cannot perform its primary business function.
Important, but can be phased if budget or deadline requires.
Not needed at launch, but architecture should not make it unnecessarily difficult later.
This stops a project from treating a contact form, a CRM integration and a decorative animation as if they have equal business value.
The 50-point website requirements checklist
1. Business goals and success criteria
Lead generation, ecommerce sales, bookings, credibility, recruitment, self-service, membership or another measurable outcome.
What should the most valuable visitor do: call, WhatsApp, submit a quote, purchase, book or apply?
Examples: brochure download, email signup, account creation or callback request.
Different audiences may require different journeys, landing pages or proof.
Local, state-wide, India-wide, international or remote delivery changes content, location pages and lead qualification.
2. Pages and information architecture
Home, About, Services, Products, Industries, Locations, Resources, Contact and legal pages as genuinely required.
Dedicated pages usually explain high-value services better than one overloaded “Services” page.
Create them when customer needs, examples, workflows or proof differ meaningfully by industry.
Location pages should add real service, logistics or market relevance—not simply swap city names.
Blog posts, case studies, jobs, events, products, FAQs, resources, team profiles or portfolio items may need reusable templates.
3. Lead-generation and conversion features
Decide which action should dominate the site and which actions are secondary.
Specify required fields, conditional questions, file uploads, confirmations and which team receives each enquiry.
Mobile click-to-call, WhatsApp prefilled messages and business hours should be intentional.
Available slots, staff calendars, confirmations, cancellations and payments may require third-party integration.
Every form or booking should confirm success and support reliable conversion tracking.
4. Ecommerce requirements, if applicable
Simple products, variants, bundles, subscriptions, digital products or services all require different catalogue logic.
Payment gateways, COD, partial payment, international currency and refund process should be confirmed early.
Zones, rates, free-shipping thresholds, courier integrations, pickup and delivery-time communication.
GST, invoice generation and tax treatment should align with the business’s accounting process.
Stock, backorders, low-stock alerts, returns, cancellations and ERP/accounting synchronization where required.
5. CMS, content and editing
Business staff, agency or both. This affects CMS choice, editor permissions and training.
Text, pricing, team, services, FAQs, banners, products and locations should be identified explicitly.
Editors should not automatically receive access to payments, plugins, hosting or other sensitive settings.
Count existing pages, posts, products, files and media that need to move, merge, rewrite or retire.
Clarify who writes copy, supplies images, creates graphics, uploads data and approves final content.
6. Integrations and business systems
HubSpot, Zoho, Salesforce or another CRM may require field mapping, lead source capture and automation.
Email marketing, transactional email, Meta Pixel, Google Ads, remarketing and consent requirements.
ERP, inventory, courier, accounting, booking, LMS, membership or custom internal systems.
Document what data needs to move between systems, how often and who controls the API credentials.
What happens if the CRM, payment gateway or external API is unavailable? Critical workflows should fail gracefully.
7. SEO and discoverability requirements
Google’s technical minimum is straightforward: Googlebot must not be blocked, the page should return HTTP 200, and it needs indexable content.
Services, categories and locations should not depend on fragile temporary URLs that will be changed immediately after launch.
Important pages should be reachable through crawlable links; Google recommends standard link structures so pages can be discovered.
Existing URLs, duplicates, protocol/domain variants and retired pages need a migration plan where relevant.
Clarify which structured data types genuinely apply and who will verify indexing after launch.
Current Google references: technical requirements, SEO for developers and canonicalization guidance.
8. Accessibility and responsive requirements
Menus, forms, dialogs and interactive components should not require a mouse-only interaction.
Inputs should have programmatically associated labels, clear required-field guidance and understandable error feedback.
Meaningful images need useful alt text; decorative images should not create noise for assistive technology.
WCAG 2.2 Level AA specifies at least 4.5:1 for normal text and 3:1 for large text, subject to defined exceptions.
Navigation, forms, tables, cards and CTAs should remain usable on mobile rather than merely shrinking visually.
Accessibility reference: W3C WCAG 2.2 Quick Reference. Accessibility requirements should be scoped according to the business, jurisdiction and risk profile.
9. Performance, security and reliability
Hosting, CMS, payment and admin access should use secure credentials and appropriate roles.
Frequency, retention, off-site storage and who is responsible for restore testing should be documented.
Who updates CMS core, plugins/apps, themes, dependencies and security patches after launch?
Optimize images, scripts, fonts and templates for real mobile users; use Core Web Vitals and PageSpeed diagnostics as signals rather than chasing a cosmetic score only.
Lead-generation and ecommerce sites should have a way to detect outages, form failures or checkout problems.
10. Analytics, ownership, handover and support
GA4, Search Console, Google Ads/Meta events, ecommerce revenue, forms, calls and CRM lead outcomes as appropriate.
The business should know who controls the domain registrar, hosting, CMS, analytics, Search Console, ad accounts and payment gateways.
Premium plugins, Shopify apps, themes, email services and APIs can create ongoing costs that should appear in the proposal.
Admin credentials, documentation, basic CMS training and technical handover should be agreed before final payment/launch.
Clarify bug-fix period, response expectations, maintenance, backups, content changes and how future development is priced.
Turn the checklist into a simple requirements sheet
For each requirement, add one of three statuses and one owner.
| Requirement | Priority | Decision | Owner |
|---|---|---|---|
| CRM integration | Must-have | Zoho CRM; map service + source fields | Developer + sales team |
| Blog/resources | Should-have | Reusable WordPress post template | Developer |
| Multilingual | Future phase | Architecture must allow future Hindi version | Developer |
| Product photography | Must-have | Business to provide before upload | Client |
This becomes much easier to estimate than a WhatsApp message saying “Need a professional dynamic website with all features.”
Requirements change by website type
Focus on service architecture, forms, calls, CRM, trust, analytics and qualified lead routing.
Add catalogue, variants, payments, taxes, shipping, inventory, order emails, returns and product feeds.
Prioritize expertise, credentials, case studies, appointment/enquiry flows and strong privacy controls.
Add roles, authentication, dashboards, access rules, data privacy and account support workflows.
Add location architecture, branch data ownership, local conversion routing and scalable location templates.
Add user stories, permissions, data model, API requirements, edge cases, performance and acceptance criteria.
Extra requirements for a redesign or rebuild
If an existing website is being replaced, the new project inherits more than its visible content.
Know which pages receive organic search, backlinks, paid traffic or direct customer use.
Do not discover redirect requirements after the old site has already been replaced.
Rebuilds frequently break hidden operational workflows because only visual pages were documented.
Plan tags, Search Console ownership and ad landing pages before launch.
Use the Redesign vs Rebuild guide and Website Migration SEO Checklist where an existing site is involved.
Use requirements to compare development quotes fairly
A low quote can simply contain fewer requirements. A high quote can contain work you do not need. Ask every provider to respond against the same checklist.
| Ask the developer to mark | Meaning |
|---|---|
| Included | Part of the quoted price and deliverable. |
| Optional | Separate price; can be added now or later. |
| Third-party cost | Requires external subscription, licence, API or payment fee. |
| Client responsibility | Business must provide data, content, account or approval. |
| Out of scope | Not included and would require a change request. |
Requirements red flags before you sign a development agreement
Nobody has defined what “finished” means for important forms, ecommerce or integrations.
The new site is quoted, but nobody owns redirects, content transfer or SEO preservation.
Domain, analytics or payment access may become difficult to transfer later.
Ask whether that means metadata only or also architecture, redirects, canonicals, sitemap and Search Console.
Annual licences, apps, hosting and maintenance should not appear as surprises after launch.
Bug fixes, maintenance and new feature requests need different rules.

Frequently asked questions
What are website requirements?
Website requirements describe what the website must do and the constraints it must meet, such as pages, user actions, forms, ecommerce, integrations, CMS editing, SEO, accessibility, analytics, ownership and post-launch support.
Do I need all 50 requirements?
No. The checklist is intentionally broad. A simple service website may need only a subset, while ecommerce, portals and custom applications need more. Mark each item as must-have, should-have or future phase.
Who should write website requirements?
The business should define objectives, users, workflows, content and operational needs. A developer or agency should help translate those needs into technical requirements and identify missing dependencies.
What is the difference between functional and non-functional requirements?
Functional requirements describe what the website does, such as forms, checkout or booking. Non-functional requirements describe qualities such as performance, accessibility, security, availability and maintainability.
Should SEO be included in website requirements?
Yes. URL structure, crawlability, internal links, redirects, metadata, canonical handling, sitemap and Search Console are much easier to address during development than after launch.
Should accessibility be included before design starts?
Yes. Accessibility affects color, forms, keyboard behavior, content structure and interactive components, so it is more efficient to scope it before the interface is built.
Can Vylino convert this checklist into a development scope?
Yes. Send the completed items—or simply the ones you know—and Vylino can help identify the remaining decisions and prepare a practical development scope.
