Listing Settings

SKU Generation

Choose a SKU source, build a format, and set missing and duplicate SKU rules.

Last updated 2026-09-08

In short

Choose whether SECND generates SKUs, reads them from product photos, or expects manual entry. If you generate them, build and publish a format before creating new products.

Choose a SKU source

1.

Open SKU format

Open Listing Manager → SKU format.

Generate automatically builds a SKU from your saved format. Read from product photos looks for a photographed label. Enter manually leaves the value for staff to type during listing.

Note

SKU source and format validation are separate. Turning format validation on does not switch products to automatic generation.

Build a format

Start with a preset or add up to eight sections. Available sections include product data such as brand, category, size, cost, and consignor, plus fixed text, dates, batch, and a sequence. Reorder the sections and choose a separator while watching the SKU preview.

A section can define its own formatting. For example, brand can use initials, cost can use whole units or cents, and dates can use short or padded values. Generated letters use uppercase for consistent scanning.

Sequence settings

A sequence gives each generated SKU a changing number. Choose its digit count and when it resets. A sequence that never resets is the simplest choice when every SKU must stay unique across the catalog.

Heads up

Format changes apply to new SKUs. Existing products keep the SKU they already have.

Validation and policies

Turn on Validate entered SKUs to compare typed or photographed values with the saved format. For missing SKUs, choose whether SECND warns, blocks publishing, or omits the SKU. For duplicate SKUs, choose whether SECND warns or blocks.

Publish or save the finished SKU settings before relying on them during intake. Test one new product and confirm its preview, separator, and sequence.
