A track or release can carry identifiers beyond its own ISRC or barcode. External ID is a reference for your own systems. Aliases are extra identifiers that Qlero matches incoming sales against. Only aliases change what matches.
Editing external IDs and aliases requires write access to Repertoire. Without it you can read both, but the fields are disabled.

External ID

External ID is a optional field on the track and release forms, that can be used to store the item’s identifier in another system, such as a distribution platform or your own database. It is available for cross-referencing and export, but Qlero does not use it for sales matching.

Aliases

An alias is an extra identifier that Qlero will match a sale on. When a sales file quotes a code that is not the track’s ISRC but is one of its aliases, the sale still lands on that track. The usual cases are a second ISRC for the same recording, or a distributor’s own product code. You can also map a YouTube asset to a track by adding the asset ID as an alias, so sales reported against that asset land on the right track. Releases work the same way alongside their barcode and catalog number.

Adding an alias

1

Open the track or release, then the Aliases tab

The tab lists the aliases the item already has and counts them above the list.
2

Click + Add alias

Type the identifier. Qlero checks it as you type and tells you if it is already taken.
3

Save

Remove an alias with the x beside it. Nothing takes effect until you save.

Rules

Unique within its own type. A track alias cannot duplicate another track’s alias or ISRC. A release alias cannot duplicate another release’s alias, barcode, or catalog number. Not case-sensitive. ABC123 and abc123 count as the same alias, so you only need one of them.

Other ways aliases get added

  • From a sales file: when you link an unmatched sale to an existing track, Qlero saves the code from the file as an alias, so later sales quoting it match on their own. See Adding new tracks and releases.
  • From an Excel import: the Aliases column takes several values separated by semicolons. An import sets the whole list, so keep existing aliases in the row if you still want them. See Importing and exporting repertoire.

Next steps

Aliases pay off when sales arrive. Import a file and see what matches. See Income. To set aliases across your whole catalog at once, Importing and exporting repertoire covers the Excel route.
