FAQ
Can you convert my Excel or Google Sheets calculator?
Yes. Provide the formulas and several sample calculations with expected results. I can reproduce supported spreadsheet logic as a responsive web calculator. Macros, add-ins, and complex multi-sheet dependencies may require a custom offer.
Which website platforms do you support?
I can integrate calculators into WordPress, WooCommerce, Shopify, Wix, Squarespace, Webflow, and custom HTML, PHP, or JavaScript websites. Please confirm your platform before ordering.
How do I choose the right package?
Basic covers one simple calculation path with up to 6 inputs. Standard supports up to 15 inputs, conditional logic, and lead capture. Premium supports complex server-side logic and one database, API, or CRM integration.
What counts as one input?
An input is one visitor field or choice, such as a number field, dropdown, checkbox, slider, text field, or date field.
Can the calculator capture leads or send results?
Yes. It can collect contact details, email results, generate a PDF, save submissions, or send data to a CRM or Google Sheet. Some features are packages or paid extras.
Can visitors see my formulas?
Formulas running only in the browser can be inspected. For proprietary calculations, select Secure Formula Logic or the Premium package so the calculations can run server-side.
What counts as a revision?
A revision is an adjustment to the agreed design or functionality. New formulas, fields, pages, or integrations are additional scope.
Is installation included?
Basic includes embed code and a setup guide. Standard and Premium can include installation on one supported website when the required access is provided. Please confirm the platform before ordering.
