The cost of a software project depends on the work needed to deliver and operate it. A feature list is a starting point, but a useful estimate also needs to account for users, business rules, integrations, quality requirements and uncertainty.
Before comparing the totals in two proposals, check whether they describe the same product and the same responsibilities.
Start with complete user journeys
Consider an illustrative request: “Customers should be able to view their orders.” That could describe a simple read-only page. It could also require separate accounts, several permission levels, information from multiple systems, downloadable documents and support for incomplete records.
The feature label is the same. The work behind it is different.
Describe what the user needs to accomplish, where the information comes from and what should happen when something goes wrong. Ask the provider which scenarios the estimate includes.
Investigate integration assumptions
An integration is easier to scope when the interface, access requirements and data format are understood. If those details are unknown, the proposal should make the uncertainty visible.
Ask whether the scope covers authentication, data mapping, synchronization, error recovery and operational visibility. Also identify who is responsible for obtaining access and working with the other system's owner.
Where a critical interface is uncertain, a small discovery task may provide a better basis for the wider estimate.
Define the standard the software must meet
Specify the environments and devices the product needs to support. Discuss essential user journeys, expected usage, accessibility needs, release checks and any specialist review your organization requires.
Do not assume that a broad phrase such as “production ready” means the same thing to every provider. Ask for the checks and responsibilities behind it.
Include the work around the build
Design, test environments, deployment, documentation and handover all require attention. Your proposal should explain which of these are included and which are your team's responsibility.
Separate the project fee from recurring costs such as hosting, external services and an ongoing maintenance agreement. Ask what assumptions have been used, especially where costs depend on usage.
Understand how uncertainty and change are handled
A useful estimate records what is known, what is assumed and what still needs investigation. It should also explain how a new requirement affects the plan.
If a target date is fixed, discuss which scope can change. If the scope is fixed, discuss the dependencies that may affect the schedule. These conversations are more useful before delivery begins.
Compare proposals on a common basis
Use these questions when reviewing an estimate:
| Question | What to look for |
|---|---|
| What will users be able to do? | Named journeys and acceptance criteria. |
| Which dependencies are included? | Systems, interfaces and access assumptions. |
| How will quality be assessed? | Defined coverage and release checks. |
| What must our team provide? | Content, decisions, access and reviewers. |
| What happens after launch? | Handover, maintenance scope and operating responsibilities. |
| What could change the estimate? | Visible uncertainties and a change process. |
An estimate becomes useful when you can understand the work behind the number. The aim is a scope both sides can assess and a plan that makes important assumptions visible.
