Frequently asked questions

How does TWICE handle unique Lego items like mixed lots, rare sets, and individual minifigures?

TWICE is built for one-of-a-kind inventory. Each item — whether a sealed set, incomplete set, mixed kilo lot, or rare minifigure — gets its own record with serialized tracking. You can store set numbers, themes, condition notes, missing or substituted parts, photos, source, and pricing history, so you always know what you have, where it is, and how it’s performing.

Can TWICE support both trade-in programs and direct purchasing of used Lego?

Yes. TWICE supports multiple intake models in one system. You can run trade-in programs with store credit, cash payouts, or consignor splits, and you can also purchase collections outright. Costs, commissions, and payouts are all tracked at the item level, making your Lego sourcing more predictable and scalable.

Does TWICE help manage completeness, missing parts, and substitutions for Lego sets?

TWICE lets you define and standardize how you capture completeness and condition. You can record whether sets are sealed, complete, near-complete, or missing key elements, and note any substituted or aftermarket parts. These details are surfaced on your product pages, so customers get transparent information and you reduce returns and support requests.

Can TWICE connect my existing Lego webshop or marketplace accounts?

Absolutely. You can keep your current website and marketplace presence and plug TWICE in as the recommerce engine behind the scenes. TWICE manages inventory, condition data, pricing, and orders. Your existing site and channels stay customer-facing while TWICE keeps all Lego stock and sales synchronized in the background.

How does TWICE help with pricing used Lego sets and bulk collections?

With TWICE, you can combine standardized pricing rules with your team’s expertise. Set dynamic pricing by theme, set number range, condition, completeness, or time on shelf, and log your purchase costs for clear margin visibility. This helps your team evaluate collections faster, keep valuations consistent, and protect margins as you scale.
