FAQ
What information do I need to provide before you start?
Just tell me your platform (WordPress, Wix, Shopify, etc.), the type of calculator you need, and your formula or logic, even rough notes work. I'll handle everything else. Not sure? Message me and I'll guide you for free.
Will the calculator work on mobile and match my website design?
Yes, every calculator is fully responsive and built to match your brand's colors, fonts, and style, so it looks like a native part of your site.
How long does it take to build a calculator?
Most calculators are delivered in 3 to 5 days depending on complexity. Multi-step calculators with conditional logic or live data connections may take up to 7 days.
Can you build a calculator with a complex or unusual formula?
Yes, I've built calculators with multi-variable logic, tiered pricing, and conditional rules before. If you're unsure whether your formula is possible, message me your logic and I'll confirm before you order.
Do you provide support after delivery if I need to update the formula later?
Yes, minor formula or logic adjustments after delivery are handled quickly. If you need bigger updates down the line, I'm happy to discuss ongoing support.
