Reputation isn’t vanity: it shows up in your cost spreadsheet

Green reputation isn’t just a nice badge on your profile. It’s a discount on shipping cost. Mercado Livre’s shipping table is different for each thermometer color, and MercadoLíder or green sellers pay less for the same package. When your color drops, the cost goes up at the same time for all your listings above R$ 79, without you changing a single price. It’s a cost increase applied to your entire catalog at once.

That’s why I treat reputation as a cost line, not a marketing topic. And that’s why it’s so frustrating when someone loses green over three late-shipped orders in a busy week.

#What counts in the math, and what doesn’t

Three things count, all objective and measured by the platform:

Complaints opened by buyers. This is the heaviest metric, and to stay in good standing you need to keep it below 3% of sales.

Shipping delays, counted when you use Mercado Envios. Note that this metric only affects those with a minimum volume of shipped sales, so small stores sometimes don’t see the effect yet.

Cancellations made by you. This is the most self-inflicted of all, and I’ll get back to it.

What doesn’t count: the review the buyer writes about the product or the star rating. They influence conversion—a lot—but they’re not the thermometer. Mixing the two makes people waste energy in the wrong place: replying to old reviews instead of fixing the shipping process.

#Why shipping delay is the cheapest problem to solve

Because it doesn’t depend on the supplier, the carrier, or luck. It depends on you printing the label and dropping off the package on time.

In practice, almost every delay has the same cause: an order that came in after the cutoff time and no one noticed, or a Friday order that was only checked on Monday. It’s a routine problem, not a capacity problem.

Two changes solve most of it: have a fixed processing time every day—including Saturday when your category needs it—and make pickup the last step of the day, not the first thing the next morning.

In practice. A stationery store lost green in a December week. No new complaints, no defective products. Seven orders were shipped one day late because the team prioritized assembling Christmas kits. Green came back in three weeks, but in the meantime they paid the highest shipping table on the entire catalog above R$ 79, right in the busiest month of the year.

#Canceling for lack of stock is the worst possible deal

You lose the sale, lose reputation, and still upset a customer who was ready to buy. Three losses in one go.

And the cause is almost always the same: out-of-date stock across channels. The product sold on another marketplace, in the physical store, or wholesale, and the listing kept showing units that didn’t exist.

The rule I recommend is to keep a safety margin for SKUs you sell in more than one place. If you have five units left, list three. The sale you miss out of caution costs much less than a cancellation.

#On Shopee the mechanics are different, but the logic is the same

Shopee has its own seller performance indicators, with metrics for cancellations, late shipping, and dispute resolution, and consequences that range from loss of visibility to restrictions on campaign participation.

The name changes, the formula changes, but the principle stays the same: the marketplace is measuring if you can be trusted to deliver, and charges a high price when the answer gets worse.

#The two metrics to check every week

You don’t need to track ten indicators. Two are enough.

Percentage of complaints on sales from the last 60 days. If it’s rising toward 3%, look for the responsible SKU before you look for the customer. Complaints are almost never spread evenly across your catalog: usually two or three products concentrate them all.

Orders shipped late this week. The target is zero, and when it’s not zero you want to know the same day, not at the end of the month.

Everything else is a consequence. A store that ships on time and doesn’t cancel orders rarely loses its green reputation, and a store that does almost always failed in one of those two.

If you want to see the cost of this in reais, the way is to look at the margin per order with the actual shipping cost you paid. That’s what Milewa shows, and that’s where a drop in reputation shows up before it becomes a problem.
