Frequently asked questions

How does TWICE handle unique, one-of-a-kind violins?

Every instrument in TWICE is tracked as its own serialized item, not just a generic SKU. You can store detailed condition notes, setup information, maker or workshop, provenance, intake source, price history, certificates, and repairs per violin. This makes it easy to see what’s available, where it is, and what stage of the resale process it’s in — without relying on manual logs.

Can TWICE support trade-ins, consignments, and buyback programs for violins?

Yes. TWICE is built for multiple sourcing models. You can manage trade-ins and buybacks with tracked acquisition costs, or run consignment programs with defined commissions, settlement cycles, and automated payouts. All intake types live in the same system, so your used violin pipeline stays structured and scalable.

Can I connect my in-store violin sales with my online resale channels?

Yes. TWICE centralizes inventory across physical locations, pop-up events, and your online store. When a violin sells in-store or online, stock is updated in real time so the same instrument cannot be sold twice. You get one source of truth for availability, regardless of where the sale happens.

How does TWICE help standardize grading and pricing of used violins?

TWICE lets you define grading templates with the specific fields your experts use — condition, level, repairs, setup, and more — so staff capture information the same way every time. You can layer pricing rules by segment, maker range, and condition to suggest consistent price bands, while still allowing expert overrides where necessary.

Can I keep my existing website and use TWICE only for my used violin inventory?

Absolutely. You can continue using your current website as your primary brand presence and plug TWICE in as your recommerce engine. Surface used violin listings via links, embedded components, or integrations while TWICE manages inventory, orders, and lifecycle tracking in the background.
