TikTok Shop Moves at TikTok Speed. Keep Up.
TikTok Shop is part storefront, part content engine, part affiliate network, and it moves faster than any other platform in this list. Creator partnerships, LIVE commerce, shoppable videos, Fulfilled by TikTok, and a compliance layer that's still evolving: there's a lot to absorb. This glossary breaks down the TikTok Shop ecosystem term by term, so you can build with clarity instead of guessing under pressure.
TikTok & Affiliate Specifics
What is TTS?
TikTok Shop. The shorthand abbreviation for the platform itself, used commonly in seller communities, agency communications, and internal dashboards.
Why it matters: You'll see TTS everywhere in seller forums, agency reports, and tool integrations. Knowing it's simply shorthand for the platform prevents confusion when switching between TikTok's own documentation (which uses "TikTok Shop") and third-party seller resources (which frequently abbreviate it).
What is UGC (User-Generated Content)?
Content created by real users or creators that feels authentic and unscripted. On TikTok Shop, UGC-style content — filmed on phone, natural setting, genuine reactions — consistently outperforms polished brand content.
Why it matters: TikTok's algorithm and its audience both reward content that feels native to the platform. A raw, genuine product review filmed on a phone typically outconverts a professionally produced brand video because it matches how users already consume content on TikTok. Building a consistent flow of UGC through your affiliate programme is one of the highest-leverage activities on the platform.
What is a TikTok Shop Sample Campaign?
A TikTok Shop program where sellers send free product samples to creators in exchange for video content promotion. Creators apply for samples and must post within a set timeframe.
What is Commission Clawback?
When affiliate commission is reversed due to order cancellation, return, or refund. The commission is deducted from the creator's future earnings by TikTok.
What is TAP (TikTok Affiliate Portal)?
Often used interchangeably with Affiliate Programs. The system within TikTok Shop that connects sellers with affiliate creators — allowing sellers to set commission rates, manage creator applications, send samples, and track affiliate performance.
Why it matters: TAP is the engine behind TikTok Shop's creator-commerce model. Sellers who build strong TAP programmes with the right commission structure and product-creator fit consistently outperform those relying on paid ads alone, because affiliate content generates organic sales alongside any ad spend.
What is Spark Ads?
A TikTok ad format that allows sellers to amplify an existing organic creator post — running it as a paid ad from the creator's own handle, carrying all their real engagement (likes, comments, shares) into the promoted version.
Why it matters: Spark Ads are the highest-performing format for most brands because the content already has social proof baked in. Unlike cold brand ads, Spark Ads carry authenticity signals that drive stronger CTR and conversion. They require a Spark Ad authorisation code from the creator whose post you want to promote.
What is TC / OC (Total Commission / Open Commission)?
TC (Total Commission) is the full commission percentage a seller sets on a product for affiliate promotion. OC (Open Commission) is the portion of that commission made publicly available to any creator who applies — as opposed to a targeted, invite-only rate.
Why it matters: Setting your OC too low means creators won't bother promoting your product when higher-commission alternatives exist. Setting it too high eats into your margins — especially when stacked with ad spend and platform fees. Balancing TC and OC is a core part of running a profitable TikTok Shop affiliate programme.
What is an MCN (Multi-Channel Network)?
An agency or organisation that manages a roster of TikTok creators, handling their contracts, commission sharing agreements, and brand partnerships on their behalf.
Why it matters: Agencies functioning as both Creator Management Agency (MCN) and Affiliate Partners take both the TAP commission from Campaign Commission, as well as the MCN commission based on the Commission Sharing Agreement signed with the binding creators. As a seller, understanding MCN structures helps you calculate the real cost of creator partnerships — commission doesn't always flow entirely to the creator you think you're paying.
Operational Metrics
What is EDD (Estimated Delivery Date)?
The date shown to the customer at checkout by which their order is expected to arrive.
Why it matters: EDD is the promise TikTok Shop makes to your buyer on your behalf. If your fulfilment or supplier doesn't meet it, your On-Time Delivery Rate drops, your Shop Score takes a hit, and repeat purchase behaviour suffers. Sellers who consistently beat their EDD build stronger reviews and better retention than those who use it as a stretch target.
What is TikTok Shop Score?
TikTok's internal quality rating for every seller account — measuring fulfilment reliability, product satisfaction, and customer service quality on a scale that directly controls your shop's reach and privileges.
Why it matters: Low scores trigger reach throttling; high scores unlock priority placement. When your Shop Score falls below 3.0, your active participation in affiliate marketing or campaigns is terminated — all existing affiliate plans are removed, and you must reach 3.5 or higher to regain eligibility. It is both a trust signal and an enforcement mechanism.
What is FBT (Fulfilled by TikTok)?
TikTok Shop's first-party fulfillment service where TikTok stores, picks, packs, and ships your products from their warehouses, similar to Amazon FBA — though many dropshippers fulfill via third-party suppliers (like CJ Dropshipping or Zendrop) instead.
What is Cart Abandonment Rate?
The percentage of shoppers who add a product to their cart but leave without completing the purchase.
Why it matters: On TikTok Shop, where the checkout is built directly into the app, abandonment is lower than on traditional stores — but it still happens. High abandonment often points to price friction, shipping cost surprises, or a checkout flow that loses momentum. Monitoring it tells you where conversion is leaking after the hook has already worked.
Financial Metrics
What is COGS (Cost of Goods Sold)?
Total direct cost of acquiring the products you sell. On TikTok Shop specifically, accurate COGS must include supplier cost, shipping to fulfilment, and any FBT inbound fees.
What is AOV (Average Order Value)?
Average revenue per completed order. On TikTok Shop, raising AOV through bundles and LIVE upsells is one of the most efficient ways to grow revenue without increasing ad spend.
What is NR (Net Revenue)?
Total revenue after subtracting returns, refunds, platform referral fees, and payment processing fees from gross merchandise value (GMV).
What is Gross Revenue?
The total income from all sales before any deductions such as fees, refunds, returns, or discounts. On TikTok Shop, gross revenue equals your total GMV before platform fees and other costs are subtracted.
What is Gross Merchandise Value (GMV)?
The total value of all products sold through your store or platform before any deductions — returns, refunds, fees, or discounts.
Why it matters: GMV is TikTok Shop's headline performance metric and the number most often cited in seller dashboards. It looks impressive but it's not the same as revenue or profit. A seller doing $100K GMV with 25% returns and 40% total costs is in a very different position than one doing $60K GMV with 8% returns and 25% costs. Always look behind the GMV number.
What is ROAS (Return on Ad Spend)?
The revenue generated for every dollar spent on advertising — calculated as total revenue from ads divided by total ad spend.
Why it matters: ROAS is your primary advertising efficiency metric. A 3x ROAS that ignores the affiliate commission line is not really a 3x — on TikTok Shop, where creator commissions stack on top of ad costs, your true ROAS must account for both to reflect real profitability.
What is CAC (Customer Acquisition Cost)?
The total marketing and ad spend divided by the number of new customers generated. On TikTok Shop, factor in both paid ad spend and affiliate commissions when calculating true CAC.
What is Lifetime Value (LTV)?
The total revenue a customer generates over their entire relationship with your business, from first purchase to last.
What is Customer Retention Rate?
The percentage of customers who continue purchasing from your shop over a specific time period. It measures your ability to keep existing customers rather than constantly acquiring new ones.
What is Churn Rate?
The percentage of customers who stop purchasing from your store within a given time period — measuring how well you retain buyers after their first order.
Why it matters: Acquiring a new customer costs significantly more than retaining an existing one. A high churn rate signals product dissatisfaction, poor post-purchase experience, or lack of follow-up. On TikTok Shop especially, where impulse purchases are common, building repeat purchase behaviour is what separates sustainable businesses from one-hit sellers.
Inventory Management
What is GTIN (Global Trade Item Number)?
The umbrella standard that encompasses UPC, EAN, and other product identifier formats — any barcode number used to uniquely identify a product in global commerce.
Why it matters: When platforms ask for a GTIN, they're asking for whichever product identifier applies — UPC in the US, EAN internationally. GTIN exemptions exist for certain custom or handmade products, but for any mass-produced item, a valid GTIN is the foundation of a compliant, trustworthy listing.
What is UPC (Universal Product Code)?
A 12-digit barcode standard used primarily in North America to uniquely identify a product at retail.
Why it matters: Amazon, Walmart, and TikTok Shop all use UPCs to match listings to product catalogue records. Listing without a valid GS1-registered UPC can trigger listing suppression, catalogue mismatches, or counterfeit flags. Purchasing UPCs from unofficial resellers rather than GS1 is a common mistake that causes long-term listing problems.
What is EAN (European Article Number)?
A 13-digit barcode standard used globally to uniquely identify retail products — the international equivalent of a UPC.
Why it matters: Required for listing products in most European marketplaces and many international platforms. Without a valid EAN, your product cannot be properly catalogued, discovered, or processed through automated fulfilment systems. For cross-border sellers especially, EAN compliance is a listing prerequisite.
What is Inventory Turnover?
The number of times your total inventory is sold and replaced within a given period — usually calculated as COGS divided by average inventory value.
Why it matters: High inventory turnover means your capital is working efficiently — products are moving quickly and not sitting idle. Low turnover is an early warning sign of overbuying, weak demand, or pricing problems. On platforms where storage fees compound over time, low turnover products become increasingly expensive to hold.
What is Reorder Point?
The inventory level at which you must place a new order to ensure stock arrives before you run out — calculated using average daily sales multiplied by lead time, plus safety stock.
Why it matters: The reorder point removes guesswork from your restocking decisions. Rather than checking inventory levels manually and hoping for the best, a correctly set reorder point triggers replenishment automatically at the right moment — keeping sales continuous and metrics clean.
What is Safety Stock?
A calculated buffer of extra inventory held above your expected demand to protect against supplier delays, demand spikes, or forecast errors.
Why it matters: Safety stock is your insurance policy. Without it, any delay from a supplier — even a few extra days — can trigger a stockout on your best-performing products. The formula typically considers lead time variability and average daily sales to determine how much buffer is appropriate.
What is Stockout Rate?
The percentage of time a product is unavailable for purchase due to running out of stock.
Why it matters: Every stockout is lost revenue and lost ranking. Platforms penalise sellers who consistently go out of stock by dropping their algorithmic placement — and that visibility loss takes time to rebuild even after inventory is replenished. Maintaining buffer stock on winning products is non-negotiable.
What is Dead Stock Inventory?
Products that have been in your inventory for an extended period with no sales activity — unsellable at current pricing and occupying storage or cash that could be working elsewhere.
Why it matters: Dead stock is capital that's stopped moving. It ties up funds, accumulates storage fees (especially in WFS or FBT), and clutters your catalogue. The earlier you identify slow-moving inventory and either discount it, bundle it, or return it to supplier, the less damage it does to your overall business health.
What is Inventory Shrinkage?
The difference between your recorded inventory and the actual physical stock on hand — caused by supplier errors, damage, theft, or fulfilment mistakes.
Why it matters: Shrinkage silently erodes your margins. If your records show 500 units but you can only fulfil 430, you have a 14% shrinkage problem that you'll discover at the worst possible moment — during a high-demand period. Regular reconciliation between your records and actual stock prevents surprise shortfalls.
Sales & Conversion Metrics
What is Sales Velocity?
The rate at which a product sells over a given time period — typically measured as units sold per day or per week.
Why it matters: Sales velocity drives algorithmic visibility on every platform. TikTok Shop, Amazon, and Walmart all reward products with strong, consistent velocity with better placement in search and recommendations. A sudden spike in velocity (from a viral video or ad) can also trigger stockout risk if inventory isn't prepared to absorb it.
What is Conversion Rate?
The percentage of visitors or viewers who complete a purchase — calculated as orders divided by total sessions or product page views.
Why it matters: Conversion rate tells you how effectively your listing, pricing, and reviews turn interest into sales. On TikTok Shop, strong UGC content and creator social proof are the biggest conversion drivers. A high CTR with low conversion usually means the product page or reviews aren't matching the promise made in the video.
What is Units Per Transaction (UPT)?
The average number of individual items a customer purchases in a single order.
Why it matters: A higher UPT means more revenue per order without increasing your customer acquisition cost. Bundling products, offering volume discounts, or recommending complementary items are all tactics to raise UPT — and on TikTok Shop's LIVE sessions, hosts actively push UPT through real-time bundle offers.
Marketing & Advertising Performance
What is Reach?
The number of unique users who see your content or advertisement at least once. Unlike impressions, reach counts each person only once regardless of how many times they see it.
What is Ad Frequency?
The average number of times each unique user sees your advertisement. Optimal frequency ensures awareness without causing ad fatigue.
What is Attribution Window?
The time period after a user interacts with an ad during which any resulting purchase is attributed to that ad. TikTok Shop default is 7-day click-through and 1-day view-through.
What is Blended ROAS?
The ratio of total revenue to total advertising spend across all channels and campaigns combined. Unlike per-campaign ROAS, blended ROAS gives you the overall picture of ad efficiency.
What is CTR (Click-Through Rate)?
The percentage of people who click on your ad, listing, or link after seeing it — calculated as clicks divided by impressions.
Why it matters: CTR is your first signal of whether your creative, thumbnail, or listing title is working. A low CTR means you're paying to be seen but not compelling enough to be clicked. On TikTok Shop, a strong hook directly drives CTR on video ads — and a weak one drains your budget without generating traffic.
Dropshipping Specific Expressions
What is a Winning Product?
A product that converts consistently, generates strong ROI, and scales without the margin collapsing — typically validated by real sales data rather than trend assumptions.
Why it matters: Not every product that looks good in research becomes a winner in practice. A winning product has the right combination of demand, visual appeal (especially on TikTok), acceptable return rates, reliable supply, and margin that survives ad spend. Finding one is the foundation everything else is built on.
What is Product Research?
The systematic process of identifying products with strong sales potential — analysing demand, competition, pricing, margins, and trend signals before committing to a listing or supplier.
Why it matters: Listing the wrong product is expensive in time, ad spend, and supplier relationships. Solid product research answers three questions before you invest: Is there demand? Is the market too competitive? Can I make margin after all fees? Tools, platform data, and competitor analysis all feed into this process.
What are Hooks?
The opening seconds of a video or ad — typically the first 1 to 3 seconds — designed to stop a viewer from scrolling and capture their attention immediately.
Why it matters: On TikTok especially, the hook is everything. Live viewers convert at 10x the rate of regular video viewers, but they only get there if the content stops them first. A strong hook — a bold statement, unexpected visual, or direct call-out — is the difference between a video that drives sales and one that gets scrolled past in under a second. Testing multiple hooks against the same video content is one of the most impactful optimisations a TikTok Shop seller can make.
What is Blind Dropshipping?
Fulfilling orders through a supplier while removing all supplier branding, invoices, and packaging inserts — so the customer receives the product with no indication of where it actually came from.
Why it matters: Protects your supplier relationships and business model. Customers who receive a package with a supplier's name and pricing on it may go directly to the source for future orders, cutting you out entirely. Most reputable suppliers offer blind shipping by default or upon request.
