Frequently Asked Questions

Got questions? I have answers

I can convert any Excel file with formulas — pricing calculators, cost estimators, quotation tools, engineering calculations, inventory trackers, budget planners, and more. If it has formulas, I can convert it.
Depending on the complexity: Lite package takes 3 days, Standard takes 7 days, and Premium takes 14 days. Simple calculators can sometimes be delivered even faster.
Yes. I rebuild every formula and calculation in code. The web app produces the exact same results as your Excel file. I test thoroughly before delivery.
Absolutely. Every package includes an embed code. Just paste one line of code into your website and the calculator appears. Works with WordPress, Wix, Squarespace, Shopify, and any custom website.
Yes. Full source code is included in every package. You own everything. No vendor lock-in, no monthly fees for the code itself.

Standard and Premium packages include an admin panel where you can update prices, rates, and other values without touching any code.
Each package includes revisions (2, 3, or 5 depending on the plan). Additional changes after that are billed at a fair hourly rate.
