TWICE Commerce is an **operating system for circular commerce** — a complete platform built to handle the complexity of rental and resale businesses. Unlike traditional e-commerce tools designed for linear "buy once, sell once" models, TWICE is built around the unique demands of circular business models where **products have lifecycles**, **inventory is serialized**, and **every item has its own journey**. Understand why we chose an operating system approach and how it adapts to your operations, not the other way around. ## Why TWICE Commerce? Track every item through multiple lifecycles — from purchase through rental cycles, refurbishment, resale, and beyond. TWICE natively understands that products in circular commerce don't just move once. Every unit is tracked individually with its own condition, location, income, expenses, and timeline. Whether managing thousands of rental units or curated vintage pieces, handle complexity at scale. Use dynamic attributes to structure your data exactly how your business works. No forced fields, no rigid workflows — configure TWICE to match your operations, not the other way around. Sell, rent, and buy back inventory across your own online stores, retail locations, and marketplaces — all synced in real-time to eliminate double-bookings and overselling. ## Supported Sales Models Turn returns and secondhand goods into profit with condition tracking, multi-source inventory, and streamlined refurbishment workflows. All-in-one platform for seamless short-term and long-term rentals with availability management, dynamic pricing, and automated fulfillment. ## Supported Operations Beyond direct sales, TWICE handles the operational complexity that comes with circular commerce and product lifecycles: Serve customers wherever they shop — online through your storefront or in-person at physical locations. Create orders seamlessly across channels with unified inventory visibility, ensuring consistent pricing and availability whether customers browse online or walk into your store. Keep inventory, pricing, and availability synchronized in real-time across all your sales channels. Whether you sell through your own online store, retail locations, or third-party marketplaces — eliminate double-bookings and overselling with centralized control. Build comprehensive customer profiles with complete transaction history, preferences, and lifecycle value. Track every purchase, rental, return, and interaction to deliver personalized service and identify high-value customers. Accept used products from customers, appraise their condition, and offer credit or cash. Track each trade-in through refurbishment and resale with full lifecycle documentation. Process returns efficiently with **unique item identification**, **condition appraisal**, and **automated routing** (resell, refurbish, or liquidate). Track each returned unit individually to maximize recovery value. Sell customer returns, demo units, or refurbished products as distinct SKUs with **condition grading**, **item-level tracking**, and transparent condition disclosure at checkout. Transform excess inventory into profit. **Identify and appraise dead stock**, then route it through the right channel — liquidation sales, employee stores, or charitable donations with proper documentation. Log and track maintenance events, costs, and service history for every individual item. Schedule preventive maintenance, monitor repair cycles, and calculate total cost of ownership across your fleet. Manage inventory owned by third parties with **separate ownership tracking**, **automated commission calculations**, and **payout workflows**. Track consignor agreements, performance, and settlements. Oversee large fleets of equipment across multiple locations. Track utilization rates, movement between sites, service schedules, and lifecycle metrics to optimize asset performance and ROI. ## See TWICE in Action Explore the below demo stores, and see how different businesses use TWICE Commerce for their specific needs: Browse a curated collection of pre-owned items with both owned inventory and consignment listings.
