Questions
- What format does the calculator come in?
- An HTML/CSS/JS embed snippet you can drop into any website: Webflow, WordPress, Squarespace, or plain HTML. It's self-contained, no external dependencies.
- Can I request changes after delivery?
- Starter includes 1 revision round. Pro includes 3. Custom includes 30-day revisions. I'll get it right.
- What information do you need from me?
- After you book, you'll fill out a short brief: what the calculator should do, the key inputs and outputs, your branding colours, and any examples you like. That's it.
- Do I need to be technical?
- No. If you can copy and paste, you can embed it. I'll send step-by-step instructions for your specific platform.
- What if I need something more complex?
- The Custom tier (£499) covers API integrations, database-backed logic, conditional flows, and custom domain hosting. If you're not sure which tier fits, book a Starter and describe your full vision in the brief and I'll flag it if it needs upgrading.
