Smokewana: White-Label WMS & Multi-Channel SaaS
Designing an end-to-end B2B warehouse platform, zero-code storefront customizer,
and native shopping apps for licensed distributors in the US legal market.
Modernizing regulated commerce with a turn-key white-label suite
The US legal cannabis and vape industry operates under strict state regulations: mandatory 21+ age verification, seed-to-sale inventory compliance, wholesale excise taxes, and warehouse logistics. However, licensed distributors and warehouse operators were constrained by 10-year-old legacy software that couldn't sync with consumer storefronts.
At Phantasm Solutions, we engineered white-label e-commerce and logistics infrastructure for major high-volume US distributors, including American Distributors and Splash Distributors LLC. Our mission was to build Smokewana from scratch — an integrated ecosystem delivering high-traffic B2C/B2B consumer web storefronts, native shopping mobile apps (iOS & Android), a zero-code layout builder, and a robust cloud Warehouse Management System (WMS) syncing thousands of daily consumer retail and wholesale orders with backend dispatch.
Our 4-person design & product team
Transforming complex legal B2B requirements into clean software through synchronized ownership and rapid screen design.
Sainath · Product Manager
Led client discovery with US distributors and warehouse stakeholders. Translated legal compliance constraints and business goals into structured sprint requirements.
Naveen Pullagura · Lead UX & Research
Audited legacy competitor tools, mapped user journey flows, authored documentation, built wireframe skeletons for admin/dispatcher dashboards, and co-designed production UI screens.
Prakash Sannisetti · UI Designer
Architected the visual design system, color tokens, and typography. Transformed wireframes into high-fidelity UI components and created Option 2 landing page concepts.
Graphic Designer · Merchandising
Produced photorealistic 3D vape hardware mockups, promotional banners, and visual merchandising kits that enabled white-label clients to launch with retail polish.
From Wireframe Skeletons to Production Screens
Sainath brought raw inputs and compliance requirements from distributor interviews. I synthesized them into user flows, information architecture maps, and wireframe skeletons for the admin and storefront tools. Prakash and I then co-designed the production UI screens, ensuring that complex warehouse tables, delivery maps, and storefront settings were visually clean and effortless to use.
Auditing legacy tools & identifying the gaps
We audited existing enterprise warehouse tools and uncovered major operational bottlenecks holding back US distributors.
Siloed Inventory & Stockouts
Legacy software kept warehouse counts on offline servers, resulting in frequent stockouts, double-booking, and slow phone verifications. We designed real-time inventory sync across facilities and digital storefronts.
Rigid Layouts & Dev Costs
Updating a promotional banner or category required hiring developers. We built a modular zero-code customizer so business owners can change headers, footers, and brand colors in minutes.
Manual Wholesale Tier Pricing
Distributors negotiated bulk prices via offline spreadsheets. We designed an automated setup tool that applies volume case discounts and state excise taxes dynamically upon login.
Frictionless 21+ Age Compliance
Blunt overlay gates caused 40%+ bounce rates. We designed a compliant age verification pattern that stores consent securely across sessions without blocking product browsing.

Zero-Code Storefront Customizer
A visual layout builder empowering non-technical operators to customize navigation bars, headers, footers, promo carousels, and brand colors without writing a single line of code.
B2B Warehouse & Inventory Hub
Centralized multi-facility stock management: live inventory counts, barcode scanner intake, batch/lot tracking for seed-to-sale compliance, and automated low-stock PO triggers.
Fleet Delivery Dispatch & Logistics
Complete last-mile delivery infrastructure: driver route assignments, state compliance manifest checklists, digital proof-of-delivery signatures, and real-time customer tracking.
Wholesale Tier Pricing & Setup Tool
A comprehensive setup module for configuring legal licenses, warehouse zones, dynamic bulk case discounts (1-10, 11-50, 50+ cases), state tax rules, and instant B2B invoicing.

Connecting the Storefront Customizer to Client Success
Flying Kush: Flagship Dispensary Experience
To validate the white-label customizer engine, we launched Flying Kush — a production-ready shopping platform across responsive web, iOS, and Android. It directly synchronizes with Smokewana WMS for real-time inventory, features 21+ compliance verification, strain terpene profiles, and live delivery driver dispatch tracking.
Client Pitch Landing Pages & 3D Merchandising
When onboarding prospective US vape and distributor clients, our pod presented two distinct concept landing page directions. Option 1 (Naveen) focused on structured conversion architecture, clear hardware specs, and wholesale sample requests. Option 2 (Prakash) delivered bold lifestyle brand storytelling. Both were supported by photorealistic 3D vape hardware renders created by our graphic designer.
Impact achieved across US distributor partnerships
By taking a systems-first approach to UX research, wireframe skeletons, and collaborative UI production, our 4-person pod transformed an outdated industry vertical into a turn-key commercial SaaS platform.
What designing for regulated US commerce taught me
Designing Smokewana and the Phantasm ecosystem reinforced a fundamental product design truth: the best UX work happens where extreme operational complexity meets non-technical human reality.
Warehouse workers need ruthless visual clarity, high-contrast status feedback, and zero-latency barcode scanning while packing bulk orders in busy facilities. Similarly, dispensary owners shouldn't have to hire engineers just to update a promotional banner or store hours. Collaborating closely with PM Sainath, UI Designer Prakash, and our graphic designer taught me how to operate as a high-velocity product design engine — synthesizing ambiguous business inputs into defensible wireframe architectures, co-designing polished UI screens, and delivering measurable enterprise value.
