One Feature, Estimated

01 Overview

Deciding whether to build a feature is hard when you cannot tell if it is two days of work or two weeks. Describe one feature you are considering, along with your current stack, and an engineer replies with a realistic estimate in working days, the approach we would take, the parts most likely to take longer than expected, and what would make it cheaper. It is an estimate for planning, not a fixed quote, and it is written so you can hand it to any developer.

02 Deliverables

4 items

What you receive at handover

  1. D01 A realistic estimate in working days, given as a range rather than a single number
  2. D02 The approach we would take, in enough detail to follow
  3. D03 The parts most likely to take longer than expected, and why
  4. D04 One or two changes to the idea that would make it noticeably cheaper to build

03 Outcomes

What should be true once it ships

  • A realistic size for a feature for ₹300, before you commit to building it
  • An approach and risk list any developer can work from
  • A cheaper version of the idea, where one exists

04 Process

How the 4 stages run

  1. Describe You set out the feature, your stack and what it must do
  2. Question We come back once if a deciding detail is missing
  3. Estimate A written estimate, approach and risks, sent by email
  4. Discuss One round of follow-up questions is answered in writing

05 Fit & inputs

A good fit for

  • Founders deciding whether a feature is worth commissioning
  • Teams planning a sprint who need a realistic size for one item
  • Anyone comparing an internal build against buying an off-the-shelf tool

What we need from you

  • A clear description of the one feature and what it must let people do
  • Your current stack, and any constraint such as a deadline or budget

These inputs are collected through the technical brief in your dashboard after payment. The duration is counted from when they arrive.

06 Answers

Questions about this engagement

No. It is a planning estimate. If you later want a fixed-scope engagement from us, ask separately and we will scope it.

This engagement covers one. For a set of features, describe the most important one here and mention the rest.

We say so and outline how we would break it down, so the estimate still tells you something useful.

This is technology work delivered digitally — nothing is shipped. Work is delivered into systems you control within the duration stated above, and the delivery and refund policies set out what happens if a date is missed.
