The SKU: automatic linking (and the storage location)

Open the Purchases page of your dashboard (full guide: Track your purchases). Léa finds the Levi's jean she bought for €8 yesterday (a Vinted purchase arrives on its own; for a purchase made elsewhere, flea market or Leboncoin, click "Add a purchase" at the top of the page). On the purchase's row, she clicks "+ SKU" and types a short code with at least one digit: A12 (without the #: that one only belongs on the listing). She could also have clicked "Generate": Bleam suggests the next free code following your existing ones (after A12, it will suggest A13).

And the code also works backwards. You had written #A12 on some listings, and a few sold before the purchase existed in Bleam? As soon as you set the code on the purchase, those past sales attach immediately (except those where you had already typed a cost by hand).

To remember: one purchase, one code, set once. (For a lot, we will see below that one precise item can also have its own.)

One rule only: the tag (your code preceded by a #, here #A12) must be the very last word of the title or the description. Léa publishes her jean's listing and writes #A12 at the very end of the description.

Depending on how you publish:

- Publishing from Bleam (the "List for sale" button on the purchase's row)? The tag adds itself at the end of the description.
- Publishing directly on Vinted? The small Bleam panel shown on the listing form adds it as soon as you pick your purchase there.
- Listing already online? Edit it and add #A12 at the very end. That's it.

One last detail: the code must contain at least one digit. That digit is what tells it apart from a decorative hashtag like #vintage.

The jean sells for €15. Bleam reads #A12 on the listing and finds Léa's purchase. The cost fills in: the €8 paid. The profit shows: €7 (€15 minus €8). The sale gets its "Linked purchase" pill. Léa did not have to do anything.

If you had already typed a cost by hand on the sale, your entry wins, always.

Léa scales up: a lot of 100 identical jumpers for €450, bought from a wholesaler outside Vinted, to resell one by one. One shared code is enough. This is where most people get lost, so here is the image to keep: this purchase is a box of 100 tickets. All the lot's listings carry the same #PRL1 and draw from that same box. Each time a jumper sells, Bleam takes a ticket: one unit of stock off the purchase, and €4.50 of cost set on the sale (€450 divided by 100).

In practice, for a lot:

- Create the purchase by hand (Léa's comes from a wholesaler, not from Vinted): on the Purchases page of your dashboard (full guide: Track your purchases), "Add a purchase", Number of items 100, Total amount paid €450. (Lot bought on Vinted? Create nothing: the purchase is already in your list, counted as 1 item. Open its detail and click "Is this a bundle? Set the number of items".)
- Set a single code on the purchase: PRL1 (Léa makes it up: any code with a digit will do). No need for 100 references.
- Write the same #PRL1 as the very last word of each of the 100 listings. (If you publish from Bleam with the purchase linked, including in bulk from the Purchases page, the tag writes itself.)

Then everything runs itself. The resale counter climbs (x/100). The "Bundle recovery" gauge, in the purchase detail, shows how much the lot has already brought back against its €450: Léa sells her jumpers for €15, so by the 30th one sold, €450 have come back in and the gauge is full. The 70 remaining jumpers are pure profit. And when the hundredth jumper goes, the purchase turns "Resold".

A hundred listings with the same code: perfect for linking. But when a jumper sells, you still have to find the right one in the pile. That is what you write after a dot in the tag.

Léa stores her jumpers on shelves. On the listing of the jumper stored on shelf 3, she writes #PRL1.E3. On the one from shelf 7, #PRL1.E7. When one sells, this marker shows on the sale and prints on the shipping label: Léa reads E3, walks to shelf 3, and the parcel is ready.

The dot separates two roles. Before the dot: the code, the one that links. After the dot: your marker, which Bleam ignores for linking. #PRL1.E3 and #PRL1.E7 therefore link to the same purchase, exactly like a plain #PRL1. The code and the marker never contain a dot themselves: a single dot in the tag, the one that separates them.

You would rather number your items than note the shelf? Same principle: #PRL1.17 for jumper no. 17. Pick one kind of marker and keep it for the whole lot.

One last thing: the purchase sheet also has a "Location" field. It is your memo at the lot level, and when Bleam publishes a listing for you with that purchase linked, it adds it after the dot in the tag (if it fits in a tag: letters, digits, dashes). If you write your listings yourself, only what you put after the dot counts: the field does not have to match it.

In Léa's lot, one Ralph Lauren jumper is worth far more than €4.50. Two settings exist, from the simplest to the most precise.

Its cost. In the purchase detail, the bundle's items table lists each item. Léa types 40 on its row: the Ralph Lauren keeps its €40, and the remaining €410 spreads over the 99 other jumpers (€4.14 each instead of €4.50). (A hand-typed cost always wins over the automatic split.)

Its own code. Each item in the table can also get its very own reference. "Generate all" numbers every item at once, and "Copy the tags" copies the list, ready to paste into your listings. With an item code at the end of a listing, the sale links to that precise item, with its own cost. The other listings carry on with the shared #PRL1: when an item has its own code, that code wins, and the box's tickets stay for the others. The details are in Track your purchases.

The marker (what you write after the dot) shows everywhere you need it: on the Sales page, in the sale's detail and in the CSV export. It never influences linking: only the code before the dot counts.

When Bleam publishes for you with a linked purchase, the published marker comes from the purchase's "Location" field, if it fits in a tag (letters, digits, dashes). A location with a space, like "Bin B3", is never published.

Your shipping labels can print the listing's last word on the label (the "last word" option in the label settings). Since the tag is precisely the last word, it prints in full, marker included: Léa reads E3 on the label and prepares her parcel without opening Bleam.

The SKU column shows by default on the Sales and Purchases pages. On the Sales side, the code detected on the listing shows even if no purchase carries it: a grey "reference detected" pill, not clickable. Nothing is lost: create the purchase with that code, and all those sales link at once. As soon as the link exists, the pill becomes clickable and opens the original purchase.

The reference also appears on the sale's PDF invoice (see Generate invoices) and in the CSV export, linked purchase or not.
