I will build a small browser calculator or custom web tool


About this gig
Turn one small task into a browser tool with a clearly defined set of inputs and outputs. Examples include a quote calculator, a checklist or a simple estimator using rules you supply.
Basic: one screen, up to 5 inputs, one calculation flow.
Standard: up to 2 screens and 10 inputs, with result export as CSV.
Premium: up to 2 screens and 15 inputs, CSV import and export, plus local browser storage.
You receive HTML, CSS and JavaScript source files, setup notes, agreed example checks and one revision within scope.
No user accounts, payments, server database, sensitive data, medical or financial decision systems, external APIs or hosting are included. Local storage stays in the browser and is not a shared database.
Before ordering, send the exact rules, sample inputs and expected results. I will check feasibility and confirm the scope. Complex products and undefined features need a separate assessment.

FAQ
Can you build a full SaaS platform?
No. These packages cover small browser tools without logins, payments or a server database.
What does local storage mean?
Data can remain in one browser on one device. It is not a shared or backed-up database.
Will you invent the calculation rules?
No. You provide the rules and expected outputs. I implement and check the agreed examples.
How do you define a revision?
One consolidated round within the approved inputs, outputs and behavior. New features need a separate agreement.
