Custom Calculators from Global One Digital are interactive lead-generation tools and self-service utilities embedded on your site — pricing calculators, ROI estimators, sizing tools, mortgage and finance calculators, subscription cost predictors, instant quote builders. Each one designed perfectly for your specific business need, branded to fit your site, and integrated with your CRM so leads flow directly into your sales pipeline.
Standard scope: discovery to define inputs and outputs, calculation logic and edge cases; design that matches your site brand; mobile-responsive front-end; back-end logic with proper validation; CRM integration so each calculator submission creates a lead with full context; analytics tracking so you can see conversion rates from calculator interactions; admin interface where your team can update pricing, multipliers and copy without touching code.
Lead-generation forms convert at one to three percent on most B2B sites. Interactive calculators that give visitors real value before asking for contact info typically convert at three to ten percent. They self-qualify leads (visitors who use the calculator are usually serious buyers), they provide marketing data (which inputs do prospects choose most often), and they create sharable assets your audience uses and references. Worth building if your offering involves complex pricing or estimation.
SaaS companies whose pricing depends on multiple variables (team size, usage volume, features) and who want prospects to self-serve estimates. Service businesses (legal, financial, construction, consulting) where project scope drives cost. Insurance, mortgage and lending businesses where customers expect instant quotes. Ecommerce brands selling configurable products. B2B businesses with high-consideration purchases needing strong lead-magnet content.
The calculator is only as useful as its math. We work with your team — sales, finance, operations — to define realistic formulas, edge cases (what happens with extreme inputs), and how outputs should round and display. For complex calculators we run validation against historical sales data to make sure the calculator output matches what you would actually quote. The goal is calculators prospects trust because the numbers feel right.
A landing site: 4-6 weeks. A mid-size web app or ecommerce platform: 8-12 weeks. Complex multi-language platforms: 16+ weeks. Discovery call narrows it down for your specific scope.
For frontend: React, Next.js, Vue, Nuxt. For backend: Node, Laravel, Python, PHP. For CMS: WordPress (mature) and Strapi (headless). We pick the stack that fits your project, not the other way round.
Yes. We frequently embed into existing engineering teams, work in your repository, follow your code review process and hand off cleanly when our work is done.
Both. We have senior designers who specialise in B2B and SaaS. If you already have design (Figma, Sketch), we work directly from your files.
Every project includes a bug-fix window (1-3 months depending on tier). After that we offer maintenance retainers from $400/mo. Most clients stay on a retainer for ongoing iteration.
Yes. Migrations are a regular part of our work — WordPress to headless, Wix to Shopify, custom CMS to modern stack. We preserve content, redirects and SEO equity.
