I will build a custom web calculator or interactive client tool
Peter Tsavdaris
About this gig
If you have a spreadsheet, formula, or repetitive question your customers keep asking, I can turn it into a clean web tool they can use themselves.
I build custom calculators and interactive client tools for pricing, quotes, ROI, measurements, assessments, and lead capture. The goal is simple: give visitors an immediate useful answer while saving your team time.
I can help with:
- Pricing and instant-quote calculators
- ROI, savings, and cost estimators
- Spreadsheet or formula-to-web conversions
- Multi-step assessment and scoring tools
- Responsive WordPress or website embeds
- Lead capture, email results, webhooks, and CRM connections
Every project is built around your actual logic, tested on desktop and mobile, and explained clearly at handoff. I work especially well with service businesses, coaches, wellness brands, agencies, and local businesses.
Please message me before ordering so I can review the formula, inputs, results, platform, and integration requirements.

I build practical e-commerce platforms, AI-assisted websites, funnels, chatbots, CRM workflows, and customer-conversion systems for small businesses. My work includes a custom online store with a loyalty program and customer dashboard, a med-spa website and lead-conversion platform, and automated WordPress workflows.
I'm a hands-on, self-motivated builder who takes projects from idea through implementation, testing, and refinement. I use WordPress, GoHighLevel, Lovable, Supabase, Cloudflare, ChatGPT, Codex, Claude, Make, and Zapier to build reliable systems that are easy to use and maintain.

FAQ
What do you need from me to get started?
Please provide the formula or decision logic, required inputs, expected results, a spreadsheet or example if available, brand preferences, and the website platform where the tool will live.
Can you convert an Excel or Google Sheets calculator into a web tool?
Yes, provided the formulas and source material can be reproduced in a browser. I will review the file before the order and confirm the appropriate package.
Can the calculator be added to WordPress, Wix, or another website?
Usually yes. It can be delivered as an embeddable tool or a standalone web page. I will confirm platform compatibility before the order.
Can the calculator capture leads or connect to my CRM?
Yes. Lead capture, email or PDF results, webhooks, and one CRM connection are available in the Premium package or through a custom offer.
Is hosting or a third-party subscription included?
Setup and deployment assistance are included where stated, but hosting, domains, paid APIs, plugins, messaging fees, and third-party subscriptions are paid by the client.
Do you provide medical, financial, or legal advice?
No. I build the software around client-provided formulas and approved content. The client is responsible for professional validation, required disclosures, and regulatory compliance.
