Overview
Overview
In specialty tobacco retail, compliance rides on every single sale. This retailer was carrying that weight on tools never built for the trade.
Age-restricted products were checked from staff memory, and generic software kept flattening a catalog of e-liquids that splits into dozens of flavors.
I built the frontend for a point-of-sale that treats regulation as a feature, not a chore. Age verification is wired into the checkout flow itself, so no regulated sale can skip it.
The catalog tracks products down to the individual flavor, matching how the retailer stocks and sells.
Stock stays in step with that catalog as sales happen, and clear analytics put real numbers behind restocking and buying decisions — delivered July 2023.

Approach
Challenges & Solutions
Age-restricted sales
Every regulated sale hinges on age verification — the register had to enforce it, not leave it to staff memory.
Age checks in the flow
Age verification is built into checkout for regulated products, making the compliant path the default path.
Catalog of variants
E-liquid lines multiply across flavors; generic POS categories flatten the product detail this store trades on.
Specialty catalog
Detailed product categorization with e-liquid flavor tracking, mirroring how specialty tobacco is stocked and sold.
Fast, error-proof checkout
Checkout had to stay quick and unambiguous, with the regulated steps impossible to skip or fumble under pressure.
Built for speed and clarity
An interface tuned for fast, error-resistant checkout, with the regulated steps kept front and center so the compliant path is the default.
Flying blind on stock
Restock timing and product decisions needed flavor-level stock counts and sales data behind them.
Inventory & analytics
Barcode-scanned stock intake and inventory management tied to the catalog, with comprehensive analytics behind stocking and business decisions.
