“I’ve made 50 sales in the last 60 days. Previously, my reputation was calculated based on a 60-day cycle, but as soon as the new rules went into effect in September, the calculation was switched to a 365-day cycle—a single cancellation from a few months ago will now remain on my record for a full year.” This complaint from a small-to-medium-sized seller on the Mexico marketplace in an online community highlights the most direct impact of Mercado Libre’s September reputation rule changes on small-to-medium-sized sellers.

Starting in September 2026, Meikeduo will officially adjust the way it calculates seller reputation (Reputación). The core of this change is not ”how much stricter the standards have become,” but rather ”a change in the calculation period”—when your order volume falls below the new threshold, the reputation assessment shifts from ”looking at the last 60 days” to ”looking at the past 365 days.” This means that issues such as cancellations and shipping anomalies from the past full year will remain in the statistical scope for a longer period. For small and medium-sized sellers with low sales volumes, the impact of this reform will be most direct. If you are operating a Meituan store and are concerned about the effects of these reputation rule changes, you can contact Qicaiying Group to obtain guidance on store operations and reputation management. Qicaiying Group has a professional team of approximately 400 people and its own accounting firm.

I. What Has Changed in the Reputation Rules: Three Key Changes

Change 1: The threshold for the measurement cycle has been significantly raised

Take the Mexico marketplace as an example: Previously, if a seller had completed more than 40 orders in the last 60 days, the platform would calculate their reputation based on their sales performance over that 60-day period. After the new rules took effect, this threshold was raised to 101 orders. In other words:

• ≥101 orders in the last 60 days: Credit rating calculated based on the last 60 days
• Last 60 days<101单：按过去365天计算信誉

The threshold has more than doubled. A large number of small and medium-sized sellers who typically sell only a few dozen orders per month will be switched from short-term calculations to 365-day long-term calculations. Under the long-term calculation, issues such as order cancellations and delivery anomalies from the first few months will remain in the statistical scope for a longer period.

Change 2: Adjustment to the Permitted Percentage of ”Affected Sales” Under the 365-Day Cycle

If your account is calculated on a 60-day cycle, the relevant tolerance thresholds will remain unchanged. The actual change is that when your account is calculated on a 365-day cycle, the tolerance thresholds for ”affected sales”—such as order cancellations and shipping/delivery issues—will be enforced according to the new standards. This includes: seller-initiated order cancellations, shipping/delivery issues, and buyer complaints.

Change 3: The complaint rate standard remains unchanged

Whether calculated on a 60-day or 365-day basis, the percentage requirement for the complaint rate remains the same. Therefore, what sellers should really focus on this time is not simply pursuing sales volume, but rather controlling cancellation rates, shipping issues, and complaint rates.

II. Implementation Schedule by Country: Not All at Once, but in Phases

This adjustment will not take effect simultaneously in all countries. The timelines for each country are as follows:

• Chile: August 31, 2026 (Effective)
• Mexico, Colombia, Uruguay, Peru: September 9, 2026
• Brazilian: September 10, 2026
• Argentina: The week of September 14, 2026

The thresholds for calculating credibility vary by market. For example, under current rules in Colombia, sellers must complete 60 orders within the last 60 days to enter the 60-day evaluation period; in Chile, the threshold is 50 orders. Therefore, sellers cannot simply apply the 101-order standard from the Mexico market to all countries.

Sellers operating in multiple countries should pay special attention to the following: It is best to check the feedback pages for each marketplace separately to confirm the current reporting period and various metrics. The platforms update this information automatically; sellers do not need to submit a separate request.

III. The Impact of the 365-Day Cycle: Not a Punishment, but an Expansion of the Sample Size

The 365-day calculation shouldn't simply be interpreted as the platform ”penalizing small sellers.” The logic behind it is:

On the positive side: As the sample size of orders increases, the impact of one or two abnormal orders on the overall ratio may become smaller. In a 60-day cycle, if there are only 40 total orders, a single cancellation accounts for 2.51 TP3T; whereas in a 365-day cycle, with 200 historical orders, a single cancellation accounts for only 0.51 TP3T. Therefore, for sellers with a solid sales foundation but relatively low monthly order volumes, a 365-day cycle may actually result in more stable credibility.

The downside: Past issues remain on record for a longer period. If there was a spike in cancellations or delivery issues in the previous few months, these issues will continue to affect your credibility score over a 365-day cycle until they naturally roll out of the statistical window after one year.

Key Variables: The key factor in determining whether a 365-day cycle is beneficial or detrimental is whether you have accumulated enough ”healthy orders” over the past year. The more healthy orders you have, the stronger the diluting effect on abnormal orders; if you don’t have enough healthy orders, a single abnormal order will be magnified.

IV. Three Self-Assessment Recommendations for Sellers

Suggestion 1: First, check how many orders were sold in the last 60 days.

Go directly to the backend and check the number of completed orders over the past 60 days. If your sales volume hasn’t reached the new threshold, be prepared for your performance to be calculated based on your historical performance over the past 365 days. Sellers with sales volumes in the range of a few dozen orders will be most affected. Also, check your records for the past 365 days for any order cancellations, shipping issues, or other incidents, and assess the extent to which these records will impact your reputation during the 365-day cycle.

Recommendation 2: Inventory must be synchronized in real time; avoid proactively canceling orders whenever possible.

Meike Duo’s reputation assessment takes into account metrics such as seller-initiated cancellations. Frequent cancellations directly impact your reputation score. Within a 365-day cycle, each seller-initiated cancellation has a longer-lasting impact. We recommend that sellers: ensure real-time synchronization of inventory data to avoid forced cancellations due to overselling; maintain close communication with logistics providers to minimize shipping and delivery issues; and regularly monitor the three core metrics: inventory accuracy, order fulfillment rate, and voluntary cancellation rate.

Recommendation 3: Don’t just focus on GMV; pay closer attention to fulfillment quality.

The message conveyed by this rule change is clear: the platform places greater emphasis on sellers” ”fulfillment quality” rather than simply sales volume. Sellers with high GMV will still see their reputation scores drop over a 365-day cycle if they also have high cancellation rates and delivery anomalies. We recommend that sellers conduct a comprehensive self-assessment of their store’s health before the peak season begins: What is your cancellation rate over the past 60 days? What is your delivery anomaly rate? What is your complaint rate? Are all these metrics within the thresholds allowed under the new rules?

V. Reputation Ratings and Their Impact on Stores: The Chain Reaction from Visibility to Traffic

A store’s reputation (Reputación) on Meikeduo directly determines its visibility and traffic allocation on the platform:

Green Rating (Highest Reputation): Enjoy benefits such as priority placement in search results, priority submission for promotions, and priority access to the FULL warehouse. Conversion rates and traffic allocation are significantly better than those of other tiers.

Yellow Tier (Moderate Creditworthiness): Basic exposure remains normal, but some priority benefits have been lost. Submissions for peak-season promotions may be restricted.

Orange/Red Level (Low Reputation): A significant drop in exposure may result in restrictions on opening FULL positions and submitting campaign proposals; in severe cases, the store may be suspended.

In a 365-day cycle, it is easier to drop from green to yellow than to go back from yellow to green—because problem records are retained for a longer period. This means that the focus of credit management is not on ”fixing problems after they occur,” but rather on ”preventing problems from occurring in the first place.”

VII. Conclusion: The rules have changed, and operational logic must change accordingly

The key message behind Meike Duo’s September revision to its credibility rules is that the platform places greater emphasis on long-term fulfillment quality rather than short-term sales spikes. The 365-day cycle has increased the weighting of ”historical performance,” which is forcing sellers to shift their focus from ”pursuing short-term GMV” to ”pursuing long-term, healthy operations.”

For small and medium-sized sellers, the 365-day cycle isn’t necessarily bad news—it also means that the impact of one or two abnormal incidents may be diluted. But for sellers with a history of issues, this means it will take longer to restore their reputation. No matter which situation you find yourself in, the most important thing to do right now is not to worry, but to log into your account to review your data, conduct a self-assessment, and develop an optimization plan.
