Frequently asked questions

How does TWICE handle heavy and complex used gym equipment?

TWICE is built for one-of-a-kind and complex items. Each unit — from treadmills and selectorized machines to barbells and racks — gets its own record with specs, condition, location, acquisition cost, and service history. You can track where it is (warehouse, showroom, customer site), how it’s graded, and whether it’s reserved, sold, or ready to list, without relying on spreadsheets or manual checks.

Can TWICE support trade-ins, buybacks, and bulk liquidations?

Yes. TWICE supports multiple intake models in the same system. You can run consumer trade-in programs, buy used units outright, or process bulk lots from gyms and corporate facilities. For each intake, you capture costs, ownership, and payout details, so margins and obligations stay clear as inventory moves through refurbishment and sales.

Does TWICE connect my in-store showroom with my online resale channels?

Yes. TWICE centralizes inventory across your showrooms, warehouses, and online channels. When a piece of equipment sells in-store or is reserved for a project, stock updates in real time everywhere, preventing double-selling. Online orders can be routed to the best fulfillment point for local pickup, delivery, or freight.

How does TWICE help with grading, safety, and refurbishment tracking?

TWICE lets you define standardized grading schemes for different equipment types and capture detailed inspection steps: mechanical checks, electronics, frame integrity, upholstery, and more. You can log refurbishment actions, parts replaced, and test results at item level, then surface this information in listings or internal views to support pricing, warranties, and compliance with your quality standards.

Can I use TWICE alongside my existing website or ERP?

Absolutely. You can keep your existing website and use TWICE as the resale and inventory engine behind it. Connect via integrations, embeds, or custom flows depending on your stack. TWICE manages used inventory, orders, and lifecycle data, while your CMS, ERP, or POS continues to handle the elements you already rely on.
