Mercado Livre Full: when and how much stock to send

Mercado Envios Full is a powerful lever: faster delivery, more visibility in search results, and higher conversion. But it also flips a risk. Outside Full, your stock is in your own warehouse, flexible. Inside Full, you're betting upfront: send 200 units, you've committed capital and space. If they sell fast, great. If they sit, you have idle cash and possibly aged inventory fees.

That's why the Full decision isn't "yes or no." It's a replenishment calculation, SKU by SKU. And it revolves around three questions.

Question 1 — Is this SKU selling enough to justify it?

A product that sells one unit every two weeks shouldn't occupy your Full space. The first filter is volume: in the last 30 days (or your chosen window), has this SKU sold the minimum that justifies replenishment? If the answer is no, the capital and space likely yield more in another product.

Question 2 — What is the real daily demand?

Here's the number that changes everything: daily demand. If a SKU sold 189 units in 30 days, demand is approximately 6.3 units per day. That's the engine of the calculation.

But be careful: daily demand isn't a simple average. Products that sell irregularly — three in one week, zero in the next — trick the simple average. A good replenishment calculation weights recent periods more and handles intermittency. Otherwise, you over-replenish after a good week and under-replenish after a slow one.

Question 3 — How many days of coverage do you want?

"Coverage" is how many days you want the sent stock to last. The math is straightforward:

Quantity to send = daily demand × days of coverage (rounded up).

In the 6.3/day example, with 30 days of coverage: 6.3 × 30 = 189 → send ~189 units. Increase coverage to 45 days? Send more, lower risk of stockout, but tie up more capital. Reduce to 15? Less capital tied up, but you'll replenish more frequently. There's no magic number — there's your cost of capital versus your cost of stockout.

The detail almost no one looks at: the same SKU across multiple listings

A SKU often appears in more than one listing (MLB). And here lies a costly mistake: you look at one listing, see it's "in Full," and assume the SKU is covered. But sales of that SKU might be spread across three listings — one in Full, two outside. The product appears as "partially in Full."

The right way to decide is to consolidate the SKU's demand by summing all listings and see the full picture:

Outside Full (no listing for that SKU is in fulfillment): strong candidate to send, because all demand is being met outside.
Partial (some listings in Full, others not): worth evaluating consolidation, otherwise you split the SKU's selling power.
100% in Full: already covered, no suggestion needed.

When NOT to send

Slow-moving SKU: space and capital yield more in another product.
Seasonal product nearing end of season: you replenish and end up with leftovers.
Tight margin + Full fees: do the net calculation, not just the turnover one.

What to take from this article

The Full decision is per SKU, not for the whole account.
Quantity to send = daily demand × days of coverage.
Good daily demand considers intermittency, not a simple average.
Consolidate the SKU across all listings before deciding — "partial in Full" is a common trap.
Higher coverage = fewer stockouts, more tied-up capital. Choose consciously.

At Jodda, the Full suggestions screen already does this work: it aggregates the SKU's demand across all listings, classifies as "outside" or "partial," calculates daily demand handling irregularity, and suggests the send quantity based on the coverage you set. You get a ready list of "what to send and how much," not a blank spreadsheet.
