Source

Source smarter

Whether you buy bulk collections, run in-store trade-ins, accept consignments, or purchase liquidation, TWICE makes Lego intake structured and repeatable. From the first photo to recorded weight, set ID, and buy cost, every lot is tracked and ready to be parted-out, sorted, or listed.

Inspect & grade

Grade and organize with precision

If you run a lean operation, every minute spent sorting, verifying, and listing Lego matters. TWICE helps solo sellers and small teams keep bulk collections organized, manage thousands of unique SKUs without spreadsheets, and list faster across multiple channels from one clean backend.

Toy & hobby stores

Used Lego moves fast and changes daily. TWICE gives toy and hobby retailers a way to manage trade-ins, buybacks, and bulk lots with structured intake, clear pricing rules, and real-time inventory sync between physical locations and online channels — including sets, parts, and minifigures.

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.
