It is difficult to give an accurate answer to a question such as how much a system will cost without knowing the scope and expected quality. Even two projects with the same theme can require very different amounts of work.
An estimate becomes a useful decision tool when budget and scope are considered together instead of separately.
An estimate is not determined by feature names alone

Customer management might mean only registering customers, or it might include permissions, history, CSV export, integrations, and notifications. The development effort changes with each of those choices.
When requesting an estimate, explain which workflow is involved, who uses it, and how much operational detail is required.
- Number and complexity of input fields
- Permissions and approval flows
- External system integrations
- Data migration
- The scope of post-launch support
Include the cost of operating after launch

After launch, there may be infrastructure fees, small corrections, questions from users, changes to the workflow, backups, and security work. These are part of the decision even when they are not part of the initial build.
Summary
- An estimate is not determined by feature names alone
- A shared budget range makes proposals more realistic
- Consider scope and priorities together
- Include post-launch support and infrastructure costs
- Do not judge by the initial fee alone
