How to Write a Technical Brief for a Website or App: A Client's Guide

"Make us a nice, modern website" is how a lot of projects start — and often how they end up stretching into months of revisions and frustration on both sides. A technical brief isn't a box-ticking formality; it's a tool that saves budget and nerves. Here's how to put one together, even if you've never done it before.

Why You Need a Brief When You Could Just Explain It

Verbal agreements get interpreted differently: what a client considers "obvious" may never make it into the developer's estimate. A written brief locks in scope, timeline, and price, protecting both sides. For the client, it's a guarantee that the features they paid for actually ship. For the contractor, it's protection against endless "let's just add one more thing" without revisiting the budget.

What a Good Brief Should Include

• Project goal and target audience — why the site or app exists and who it's for.
• A list of pages or screens — the site structure or app map, with a short description of each section.
• Functional requirements — contact forms, a customer account, a shopping cart, filters, search, notifications.
• Integrations — CRM, 1C, payment providers (Payme, Click, Uzum), a Telegram bot, warehouse systems.
• References and anti-references — sites you like the style of, and examples of what to avoid.
• Content ownership — who's responsible for copy, photos, and translations into the required languages.
• Technical constraints — existing hosting, domain, and systems the project needs to work with.
• Timeline and budget — realistic ranges, plus the milestones payment is tied to.
• Acceptance criteria — exactly how you'll verify the work is done.

Common Mistakes Clients Make

• "Make it like our competitor, but better" — without specifics, this can't be scoped or priced.
• No references at all: everyone pictures a design description differently.
• Forgetting about content — copy and photos get prepared at the last minute, delaying launch.
• Budget and timeline set independently of scope — "two weeks and $3,000" with no link to the actual features.
• Post-launch support never discussed — who fixes bugs and adds small tweaks a month after handover.

What If You Can't Write One Yourself

You don't need to be technical to write a good brief — a clear description of the business problem and your expectations is enough. A good contractor will help turn that into a technical spec during the discovery phase. At Global Soft, every project starts with a free discovery call where we work with the client to define scope together, so both sides know exactly what's being built.

Conclusion

A good brief isn't bureaucracy — it's how a project reaches a result without stress or overpaying. The more detail you provide on goals, features, and responsibilities, the more accurate the timeline and budget will be. Not sure where to start?
