FAQ
Do I need to know coding to use it on my website?
No. I'll deliver ready-to-embed code. For WordPress, it's a simple copy-paste into any page. For Webflow or Squarespace, I'll guide you in 2 minutes.
Will it work on my WordPress / Webflow / Wix site?
Yes. The tool is built in pure HTML/JS — it works on literally any website platform, no plugins or extra subscriptions needed.
Can you make my calculator match my brand style?
Yes, included in Standard and Premium. Share your colors, fonts, and logo — I'll match it exactly to your brand.
What if my calculation logic is complex?
Message me first and describe it. I've handled tax calculations, compound interest, multi-variable ROI, and more. Most cases are doable.
Can I update the calculator myself later?
Yes. The JS code is clean and commented. Changing values or labels is straightforward even without deep coding knowledge.
