Every guitar in TWICE is tracked as an individual item with its own data: brand, model, serial number, specs, condition, mods, intake source, cost basis, and sales history. You can see exactly where each instrument is, what state it’s in, and which channels it’s listed on — without juggling spreadsheets or manual notes.
Yes. TWICE is built to handle multiple intake models in a single system. You can track trade-in values, cash offers, and in-store credit; manage consignor agreements, splits, and settlement cycles; and record outright purchases and refurbishment costs. All these flows roll up into clear inventory, margin, and payout reporting.
Yes. TWICE centralizes your inventory across physical stores, warehouses, pop-up events, and online sales channels. When a one-off guitar sells in-store or online, stock updates instantly everywhere else, reducing the risk of double-selling and keeping your team aligned on what’s actually available.
TWICE lets you define standardized grading criteria for different instrument types, so your team records the same condition details every time. You can configure pricing rules by brand, model, year, condition, and demand, while still allowing manual overrides for rare or unusual pieces. This keeps valuations consistent, defendable, and fast to execute at the counter.
Absolutely. You can keep your existing website and use TWICE as the resale engine behind it. Connect via integrations, use embedded components, or link to a dedicated secondhand store powered by TWICE. The platform manages inventory, orders, and lifecycle tracking for your used guitars, while your current site remains the front end of your brand.
