TikTok Shop this week published its comprehensive guide to the Shop Performance Score inside its US Academy, a document that lays out the full mechanics of a scoring system that determines whether sellers can access affiliate marketing, run platform campaigns, settle payments in one day rather than eight, and maintain any meaningful search visibility on the platform at all.

What the Shop Performance Score actually is

The Shop Performance Score (SPS) is a dynamic rating on a scale from zero to five. According to TikTok Shop, sellers receive a score automatically once they have delivered at least 30 orders - excluding fake orders, sample orders, or gift orders - within the preceding 90 calendar days. Sellers below that threshold do not hold a score, and the distinction matters: a null SPS is treated differently from a low SPS in several eligibility calculations across the platform.

The score rests on three dimensions: product satisfaction, fulfillment and logistics, and customer service. Each dimension is itself built from two specific metrics, giving six total input variables. The weighting applied to each metric is relative to the seller's primary category. TikTok Shop uses the shop's bestselling category over the last 90 days to determine which category benchmark applies, meaning the same raw performance figures can translate to different normalized scores depending on where a seller competes.

The six metrics in detail

Negative Review Rate (NRR) covers the percentage of delivered orders in the last 60 days that received an initial one- or two-star product review. Edits and updates to existing negative reviews do not count - only the initial rating is factored in. The performance benchmarks TikTok Shop publishes for this metric are stark. According to the document, a Negative Review Rate below 40% earns one point or less, placing a seller in the poor performance band. Reaching the excellent band of four points or more requires an NRR below 1.2%. That gap between poor and excellent is 38.8 percentage points, and the consequences of sitting near the bottom of that range compound across the other metrics.

Non-Buyer Fault Return and Refund Rate (NBFR) measures the percentage of delivered orders in the last 60 days that resulted in a return or refund request because of a problem caused by the seller or a logistics partner - damaged packaging being a primary example. This metric is based on all orders delivered and not canceled within the measurement window.

Seller Fault Cancellation Rate (SFCR) covers orders placed in the past 30 days that were canceled due to the seller's fault, which includes running out of stock, late shipping, and pricing errors. Issues tied to Fulfilled by TikTok logistics services are excluded from this calculation. The formula divides the number of seller-fault cancellations by the total number of orders that were not canceled in the same period.

On-Time Delivery Rate (OTDR) is the percentage of orders delivered by their designated deliver-by date out of all orders expected to arrive within the last 30 days. Certain product categories - made-to-order, pre-order, backorder, and custom handling items - are exempt from OTDR calculations.

IM Dissatisfaction Rate captures the percentage of chat conversations in the past 60 days where customers gave a low satisfaction rating of one or two stars in a post-chat survey. TikTok Shop excludes IM negative reviews from chatbot and FAQ channels from this calculation, with the stated aim of fairer assessment.

After-Sales Handling Time is the average time sellers take to handle refund, return, cancellation, or replacement requests in the past 60 days. It counts only requests the seller actively reviewed or set rules for - not those the system approved automatically by default. The calculation runs across two stages: the Request Approval Time, which is the initial assessment window; and, where a return is approved, the Item Inspection Time, which begins when the product has been returned and delivered back to the seller.

According to TikTok Shop's worked example, a seller with two after-sales cases - one involving a 4-hour approval and 12-hour inspection, the other a 3-hour refund-only approval - would produce an average handling time of 6.33 hours across three total review rounds.

How time-weighting changes the calculation

One technical detail that affects how quickly score changes take effect is the exponential decay applied to older orders. According to TikTok Shop, each order's impact decreases over time using a decay factor of 0.7 per 15-day period. An order delivered within the past 15 days carries full 100% weight. An order delivered 16 to 30 days ago carries 70% weight. At 31 to 45 days the weight drops to 49%, at 46 to 60 days it falls to roughly 34%. The practical consequence is that recent operational improvements feed into the score faster than the raw time windows might suggest, while older problems lose influence before the formal metric window closes.

Category benchmarks and normalization

Scores across all six metrics are normalized to a 0-to-5 scale using category-specific benchmarks rather than platform-wide averages. The document describes a two-anchor system. A performance level of one point or less indicates poor performance; four points or more indicates excellent performance. The position of those anchors varies by category, meaning a seller in one product category faces different absolute performance requirements than a seller in another.

A seller whose Product Satisfaction score falls below one triggers a specific adjustment mechanism. According to TikTok Shop, if the product satisfaction score is below one, the overall SPS is automatically adjusted to the lowest of the three dimension scores - product satisfaction, logistics and fulfillment, and customer service. This makes product quality the structural floor of the entire scoring system.

The NRR component has an additional graduated adjustment mechanism. When a negative review rate is worse than the industry average and the number of negative reviews exceeds three, the SPS is adjusted downward. The adjustment is not immediate: the document describes an escalating intensity where the impact is "very slight" on first breach and intensifies as the rate worsens.

Protections for smaller sellers

TikTok Shop applies a floor for sellers with low order volumes, including new stores and sellers of high-priced products. The protection activates when the number of affected orders does not exceed three, the number of completed orders is 30 or fewer, and the store has been operating for fewer than 180 days. Under those conditions, if a seller's score on any of the four metrics - NRR, NBFR, OTDR, or SFCR - falls below 3.5 points, the score for that metric is set to 3.5 points until either the score rises above 3.5 independently or the conditions no longer apply. For the IM Dissatisfaction Rate, the lowest score is raised to a floor of 2 points.

What the score unlocks - or removes

The benefit structure operates on four threshold levels: 2.5, 3.5, 4.0, and 4.5. Each level is cumulative, meaning a seller at the 3.5 tier retains all benefits from the 2.5 tier as well.

At 2.5, sellers gain eligibility to create and launch Flash Deals, and receive an estimated 10% increase in visibility from search and recommendations. TikTok Shop describes the visibility increase as an estimate based on historical data rather than a guaranteed outcome.

Reaching 3.5 unlocks a substantially larger set of tools. Affiliate Marketing access opens at this tier - sellers can create affiliate plans and collaborate with creators on commission-based product promotion. The platform's documentation makes the downside equally clear: when a merchant's SPS falls below 3.0, active affiliate marketing and campaigns are terminated immediately. All existing affiliate plans and campaign products are removed. A seller must reach 3.5 again to regain eligibility. The difference between 3.0 and 3.5 is the gap between a functional affiliate program and none at all.

The 3.5 tier also activates access to campaigns, which are promotional events inside the TikTok Shop ecosystem. Accelerated Settlement - reducing the standard 8-day post-delivery payment window to 5 days - is another 3.5-level benefit. Visibility is estimated to increase by 20% at this tier, compared to the 10% at 2.5. TikTok-funded promotions become available, as does CRM access for sending personalized marketing messages to customers.

CRM access has its own sub-tier behavior. When SPS sits between 3.0 and 3.5, CRM permissions are frozen - existing plans continue running, but no new plans can be created and existing ones cannot be edited. If SPS drops below 3.0, access is revoked entirely and all created plans are paused.

At 4.0, sellers become eligible for Express Settlement, which compresses payment timing from 8 days to 1 day after delivery. The Star Seller Program - covering both Gold and Silver Star Seller badges - requires a minimum SPS of 4.0. The Gold Star Seller badge applies to independent sellers with a Shop Reputation Score above 10,000, a Positive Product-Rating Rate of 80% or higher, at least one sellable product, and an uploaded shop logo. The Silver Star Seller badge carries the same criteria except the Reputation Score threshold is above 2,000 rather than 10,000. Both badges refresh monthly.

The 4.5 tier adds an estimated 30% visibility increase via search and recommendations, stacking on top of the 20% at 3.5.

Countdown Bidding and the 2.5 minimum

The SPS threshold extends beyond the benefit tiers listed in the main guide. As PPC Land reported when TikTok Shop documented its Countdown Bidding feature in June 2026, sellers need a Shop Performance Score of 2.5 or higher to list products in that auction format. A null SPS also satisfies the requirement, but a score below 2.5 excludes the seller entirely, with no override pathway in the documentation.

Smart Promotion eligibility, the platform's promotion program that has become a prerequisite for major brand campaigns, flash sales, and weekly promos, requires a minimum SPS of 3.5 for sellers who have completed at least 30 orders in the past 90 days. The SPS threshold for Smart Promotion enrollment and the SPS threshold at which affiliate marketing is revoked are the same number.

How the appeal mechanism works

TikTok Shop's guide acknowledges that score drops can result from factors outside the seller's control - buyer mistakes, logistics problems, or system errors. The SPS Appeal feature allows sellers to dispute specific metrics they believe have been calculated incorrectly. According to TikTok Shop, step-by-step instructions are provided in a separate Complete Guide to SPS Appeals document. The platform specifies that sellers can access the appeal pathway through Seller Center, under Account Health.

The broader compliance context

The Shop Performance Score sits within an expanding compliance architecture that TikTok Shop has built across 2025 and 2026. The logistics mandate issued in January 2026 ended independent seller shipping effective February 25, 2026, forcing US merchants into TikTok Shop Logistics Services or a restricted list of approved providers. That structural change affected the Seller Fault Cancellation Rate and On-Time Delivery Rate metrics directly.

TikTok Shop's tightening of content and listing policies in May and June 2026 introduced posting limits, made-in-USA origin claim rules, and the upcoming replacement of the Violation Points system with an Account Health Rating from July 2026. The AHR operates differently from the SPS but intersects with it: Smart Promotion requires an AHR above 150, and Countdown Bidding carries the same AHR threshold alongside the 2.5 SPS minimum.

The Creator Enforcement Policy published on June 2, 2026 formalizes a 90-day repeat-violation window for creators, and commission freezes that can extend settlement timelines from the standard 15 days after delivery to 31 days. The SPS operates in parallel with the Creator Health Rating (CHR) that governs the creator side of the same affiliate relationships.

The Promotion Performance Score (PPS) introduced on June 3, 2026 rates affiliate creators on a 0-to-5 daily scale, with thresholds of 2.5 and 4.0 unlocking specific reach amplification and badges. Sellers whose SPS falls below 3.0 lose affiliate access - at the same moment that creators whose PPS falls below 2.5 lose enhanced distribution. The two scoring systems are not technically linked, but they share the same commercial outcome: a gap in either score disrupts the seller-creator commerce relationship.

For the marketing community, this architecture matters because it determines which sellers are accessible to affiliate programs at all. A brand or media buyer building a TikTok Shop affiliate strategy needs to understand that the pool of eligible sellers is defined not just by product category or price point, but by six time-weighted performance metrics evaluated against category-specific benchmarks. TikTok Shop's DFYD campaign guide from June 4, 2026 illustrated the layered nature of this scoring infrastructure: even a seller who enters a campaign in good standing can lose access mid-event if their scores shift. The same logic applies to the SPS - a seller at 3.6 today is one logistics cluster away from dropping below 3.5 and having their affiliate plans removed.

TikTok Shop reached $15.82 billion in US e-commerce sales in 2025, growing 108% year over year, according to EMARKETER data cited by TikTok. At that scale, the scoring infrastructure is not a peripheral compliance detail. It is the mechanism that determines which fraction of the seller base can access the promotional tools, payment timing, and creator partnerships that make competing at scale viable. Sellers who track their SPS only when a benefit disappears are engaging with the system in reactive mode. The guide published today makes the mathematics of that system visible in enough detail that proactive management is possible.
