How to write a software brief that gets accurate quotes

A good software brief fits on one or two pages and covers six things: the business goal, who will use it, the three to five workflows that matter most, the systems it must connect to, the data it will hold, and your constraints on budget, time and ownership. Screens and features come later; workflows are what vendors can price accurately.

Why do quotes for the same project vary so much?

Because each vendor fills the gaps in a vague brief with their own assumptions. One assumes a simple admin panel, another assumes role-based access, offline mode and five integrations. A precise brief removes those guesses, so the quotes you receive are for the same thing and you can compare them.

What should a software brief include?

  1. Goal: the business result in one sentence — "cut the time from enquiry to invoice", not "build an ERP".
  2. Users: every role that will log in (owner, sales, accounts, field staff) and roughly how many of each.
  3. Workflows: the three to five journeys that matter most, written as steps — "a lead comes in from IndiaMART, sales calls within an hour, a quotation is sent, the customer accepts, a proforma is raised".
  4. Integrations: every system it must read from or write to — accounting, WhatsApp, payment gateway, email, existing spreadsheets — and whether they have an API.
  5. Data: what records it holds, what already exists and must be migrated, and anything sensitive (health, finance, personal data).
  6. Constraints: budget range, launch date, platforms (web, Android, iOS), languages, and who must own the code, hosting and data afterwards.

What should you leave out of the brief?

  • Detailed screen designs — they fix decisions before the workflows are agreed.
  • A technology stack, unless you have a real reason (an in-house team, an existing platform).
  • Long feature wish-lists without priorities — mark each item must-have, should-have or later.

What does a good workflow description look like?

Vague versus priceable requirements
VaguePriceable
CRM with lead managementLeads arrive from the website, IndiaMART and walk-ins; each is assigned to a salesperson who must log a follow-up within 24 hours; overdue follow-ups show on the owner's dashboard
Inventory moduleGoods are received by scanning a barcode; stock reduces when an invoice is raised; alert when a product falls below its minimum level
ReportsA monthly lead-to-invoice conversion report by salesperson and lead source, exportable to Excel

What should happen after you send the brief?

A serious vendor should come back with questions, not just a number. Expect a short discovery call, a written scope that restates your workflows in their words, and a quote broken into stages or milestones. If a quote arrives with no questions at all, the gaps in your brief have been filled with assumptions you have not seen.

How long should a software brief be?

One to two pages is enough for an accurate first quote. Longer documents usually add screen-level detail that is better decided with the vendor during discovery. What matters is that the goal, users, key workflows, integrations, data and constraints are all stated clearly.

Should I include a budget in the brief?

Yes, as a range. It lets vendors propose the right scope for your money instead of their largest version, and it saves both sides time when the expectation and the scope are far apart.
