# Granular Billing with Pick Charge Subtypes

> Differentiate pick charges by subtype — full, part, and pickface — so you can automate distinct rates for each type of pick task.

The billing engine supports **pick charge subtypes**, giving you more precision over how warehouse operations are charged. You can apply different rates to full, part, and pickface picks, all automated through your charge cards.

## How it works

The system recognises three distinct pick scenarios:

* **Full**: triggered when the entire contents of a pallet are picked (for example, 10 of 10 items).
* **Part**: applied when only a portion of a pallet's stock is picked (for example, 5 of 10 items).
* **Pickface**: triggered whenever stock is picked from a designated pickface location.

## Applying a subtype

<Steps>
  <Step title="Open the charge card">

  </Step>

  <Step title="Assign the subtype">
    Assign the desired subtype — **Full**, **Part**, or **Pickface** — to your charge line.
  </Step>
</Steps>

## Important considerations

To keep your billing accurate, keep the following in mind:

<Warning>
  **Unit of Measure (UoM):** if you set your UoM to **Item**, you lose the ability to charge for full pallet picks separately.
</Warning>

<Note>
  **Rate card alignment:** make sure charges are applied against the correct task type — for example, distinguishing pallet pick rates from case or item pick rates — so they stay aligned with your specific rate cards.
</Note>
