Frequently asked questions

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

TWICE is built for single-item inventory. Each antique is tracked as its own record with serialized ID, photos, condition notes, provenance documents, purchase terms, and pricing history. You always know where a piece is, which channel it’s listed on, and what has been promised or sold — without relying on manual logs or memory.

Can TWICE support both consignment and owned antique inventory?

Yes. TWICE is designed for mixed intake models. You can manage consignor agreements, commission rates, payout schedules, and settlement reporting, alongside items you purchase outright. Both workflows run in the same system, so you can see true margins and profitability across consignments, buyouts, and estate purchases.

Does TWICE help with provenance and authenticity records?

TWICE lets you attach provenance documents, certificates, appraisals, expert opinions, and correspondence directly to each item. These records stay with the item through its lifecycle and can be selectively surfaced in listings or retained for internal reference, helping reinforce trust with buyers and partners.

How does TWICE connect showroom, fairs, and online antique sales?

TWICE centralizes inventory across your physical shop, warehouses, fairs, and online channels. Items reserved or sold at a fair or in-store update stock in real time, preventing double-selling online. You can manage holds, private offers, and public listings in one backend — while using whichever front-end channels fit your clientele.

Can TWICE support complex shipping and handling for antiques?

Yes. TWICE supports flexible shipping workflows, including custom quotes, white-glove delivery, in-store pickup, and local courier options. You can set shipping rules by category, size, weight, or price point, and capture packing and insurance requirements as part of each order’s workflow.
