# What SKU Fields Can Lightspeed R-Series Sync to SKU IQ?

## SKU IQ can be customized to accept the Custom SKU, Manufacturer's SKU, or System ID in Lightspeed as the SKU number field.

SKU IQ can be customized to accept the Custom SKU, Manufacturer's SKU, and System ID in Lightspeed as the SKU number field. By default, SKU IQ reads the Custom SKU field. You can request that we modify that by [contacting Support.](https://lp.skuiq.com/support?hsLang=en)

| SKU Field | Description |
| --- | --- |
| System ID | This is a read-only field assigned by Lightspeed Retail R-Series that is also used on labels that you can print via Lightspeed. |
| Custom SKU | Any code or sequence that you would like to use to lookup an item quickly on your Point of Sale. (Check out [this information](https://knowledgebase.skuiq.com/knowledge/data-formatting?hsLang=en#gen-sku) on creating your own SKUs!) |
| Manufacturer's SKU (Manfact. SKU) | This is the Manufacturer's identification number (NOT the UPC or EAN)! |
