Terms you’ll come across while using Sideboard.
Sideboard terms
Buylist — A published list of cards your store will buy from customers at set prices. Customers visit your buylist page, add cards they want to sell, and submit an order. You receive the cards, grade them, and pay out.
Catalog (or Catalogue) — The full set of card products Sideboard knows about for a given game. Refreshed daily from our data source. You don’t manually add products to the catalog — it’s the source-of-truth pool from which you build inventory.
Calculated price — The sell or buy price that pricing rules produce for an item. Stored alongside the item so it doesn’t need to be recomputed for every page load. Recalculates automatically when the underlying market price or rule changes.
Card detail — The game-specific attributes of a card (e.g., a Magic card’s mana cost, a Yu-Gi-Oh card’s ATK/DEF). Used by pricing rules and filters.
Card game — One of the eight TCGs Sideboard supports: Magic: The Gathering, Yu-Gi-Oh!, Pokémon, One Piece, Star Wars Unlimited, Gundam, Disney Lorcana, and Riftbound. Each is subscribed to separately.
Condition — The grade of a single card: Near Mint, Lightly Played, Moderately Played, Heavily Played, Damaged. Prices vary by condition.
Customer — A person who sells to or buys from your store. Has a record in Sideboard with contact info, transaction history, and store credit balance.
Edition — A printing run for some games (e.g., Yu-Gi-Oh’s 1st Edition vs Unlimited vs Limited). Editions affect price and SKU.
Inventory — Your actual stock: a list of items you physically have, with quantities, conditions, variants, languages, editions, and prices. Distinct from the catalog (which is every possible product).
Inventory item — A single line of stock: one product in one condition+variant+language+edition combo, with a quantity and price.
List price — The number you’d put on the price tag. Comes from either a manual override or a pricing rule.
Manual override — When you set an item’s price by hand instead of letting pricing rules compute it. Useful for one-off items (signed cards, errata, rare conditions).
Market price — The reference price Sideboard pulls from our market data feed. Refreshes every 6 hours for in-stock items, every 24 hours for everything else.
Pricing rule — A pattern that says “when these conditions match, use this price formula.” For example: “All Modern Standard staples in NM = 95% of market price.” Rules cascade in order — the last matching rule wins.
Presale — A product that hasn’t been released yet but is already listed in our catalog source. Sideboard reads the presale signal and flags affected products throughout the system (catalog badge, special tag on Shopify, hidden from customer-facing buylists, excluded from CardTrader).
Product — A specific card identity in the catalog (e.g., “Lightning Bolt from Strixhaven Mystical Archive, JP Alt Art”). Distinct from an inventory item, which is a specific copy you own.
Quantity rule — A buylist rule that caps how many copies of each matching card you want to buy.
Set — A release of cards from the game publisher (e.g., MTG’s “Bloomburrow”, Yu-Gi-Oh’s “Battles of Legend: Glorious Gallery”). Sets have codes, names, and release dates.
SKU — A unique identifier for a specific inventory item, used for in-store scanners and Shopify catalogs. Generated automatically.
Store credit — A balance a customer holds with your store, usable on future sales. Issued from buylist payouts, sales refunds, or manual adjustments.
Variant — A finish or special edition of a card: Normal, Foil, Etched, Showcase, Borderless, Holofoil, etc. Variants are priced separately from normal cards.
TCG industry terms (Sideboard adopts the same vocabulary)
Bulk — Common, low-value cards. Bought in large quantities at flat per-card rates rather than individually priced.
Etched (foil) — A foil treatment with a distinct stamped pattern. MTG-specific.
Foil — Cards with a metallic shimmer treatment. Priced separately from non-foils.
LGS — Local Game Store. The kind of business Sideboard is built for.
MSRP — Manufacturer’s Suggested Retail Price. Sealed product reference.
Reverse holofoil — Pokémon-specific. A foil treatment on commons/uncommons (opposite to “holofoil rare”).
Sealed — Boxes, packs, and bundles — products that haven’t been opened. Distinct from singles (individual cards).
Singles — Individual cards. The other half of TCG inventory, alongside sealed.
TCGPlayer — The largest secondary marketplace for trading cards in North America. Their data feeds power most pricing in the TCG ecosystem.
Variant — See above.
