Used instrument inventory is highly unique. TWICE uses single-item tracking so every instrument has its own profile with specs, condition, serial number, intake source, cost, price, and history. You always know where a piece is, what it’s worth, and which channel it’s listed on — without relying on manual spreadsheets.
Yes. TWICE is built to handle multiple intake models in parallel. You can manage trade-in deals, buybacks, and outright purchases alongside consignor agreements, commission structures, and payout cycles. All flows live in one system, so sourcing secondhand instruments stays organized and scalable.
Yes. TWICE centralizes inventory across physical stores, warehouses, and your online channels. When you take in a trade and list it, stock updates in real time wherever you sell, so you don’t double-sell one-off instruments. In-store POS flows and online checkout run on the same inventory source of truth.
TWICE lets you define grading criteria tailored to instruments — from fret wear and hardware condition to replaced parts and repair history. Your team captures this data during intake, then applies pricing rules by brand, model, category, or condition. That keeps valuations consistent across staff and locations while still allowing expert overrides when needed.
Absolutely. You can keep your current website and use TWICE as the engine behind your secondhand program. Link out to your resale catalog, embed components, or integrate via APIs depending on your setup. TWICE handles inventory, pricing, orders, and lifecycle tracking — your main site remains the primary brand destination.
