The Opportunity

An app that lets merchants price products by area, including irregular shapes, with quoting rules and safeguards against undercharging. It would support flooring, rugs, fabrics, sheet goods, stone, and other made-to-measure products.

"Merchants selling custom-sized products struggle to price irregular shapes accurately without manual quoting, which causes underpricing, slow fulfillment, and inconsistent margins."

Detailed Analysis

Proposed Solution

Provide a visual or formula-based calculator where customers enter dimensions, upload shape sketches, or choose predefined shape types. The app calculates area, applies pricing rules, adds waste/margin buffers, and can route complex requests to manual approval before checkout.

Target Audience

Shopify merchants selling custom-sized materials such as flooring, rugs, textiles, countertops, signage, and sheet goods

Competitive Landscape

Measurement Price Calculator, Price On Request apps, custom product options apps with dimension pricing, product configurator apps

Implementation Notes

Build product-level pricing rules based on unit area, linear dimensions, minimum charge, waste factor, rounding rules, and optional bounding-box vs true-area modes. Add file upload or sketch input for irregular shapes, admin approval workflows, estimate-to-order conversion, and safeguards to prevent checkout underpricing.
