I will build a web calculator, quote calculator, pricing tool, or excel to web
Humam
Acerca de este Servicio
Do you need visitors on your website to get an instant price or quote, instead of guessing or waiting for a manual reply?
I build custom web calculators that turn your pricing logic into a clean, working tool: enter a few details, get an instant result. No generic templates. I work out the calculation logic around your actual business rules first, then build it clean in HTML, JavaScript, and PHP.
I run a digital agency where I use these exact tools every day, including a financial dashboard that processes 31 months of real business data and a 10 module ERP that runs my own company's invoicing and finance. Every calculator I deliver is shaped by that same operational thinking, not a tutorial project.
What you get:
A calculator built around your specific formula and inputs
Clean, responsive design that works on mobile and desktop
A source file you fully own
A clear explanation of how the logic works, so you are never locked in
Common use cases: service quote estimators, cost or production price calculators, shipping or fee calculators, savings or ROI calculators
Message me with your pricing rules or an example calculation, and I will confirm the exact scope before you order

Hi, I'm Humam. I build practical web tools for small businesses and freelancers: pricing calculators, conditional order forms, and custom business dashboards.
I run a digital agency and use these exact tools daily: a 10 module ERP for clients and invoices, a production dashboard for a food business, and a dashboard for a government transportation department.
Every tool I build is shaped by real operational needs. I get the logic right first, then build it clean in PHP, MySQL, and JavaScript.
If you need a tool that reflects how your business runs, let's talk.

FAQ
Can you build a calculator without me writing any code?
Yes. Just describe your formula and the inputs you need, or send an example calculation, and I will build the entire tool for you.
Can I add my calculator to my existing website?
Yes. I can deliver a standalone file you host yourself, or set it up to embed directly into your existing site.
What if my pricing logic changes later?
You get the full source file, plus a clear explanation of how the logic works, so you or another developer can update it. I also offer ongoing edits as a separate order.
Do I need to provide a working formula myself?
Yes, or at least a clear example calculation with sample numbers and the expected result. If you are unsure how to define it, message me and I can help clarify it before you order.
Can the calculator export results as PDF or send them by email?
Yes, this is included in the Premium package.
