Adjustments
Adjustments let you add charges or discounts without editing line items. They support percentage or fixed amounts and respect tax classes. Access requires order/quote manage plus sales.settings.manage to curate kinds and tax rates.

Add an adjustment
- Open Adjustments on the order/quote and click Add adjustment.
- Set label and optional code for reporting.
- Choose adjustment kind (Shipping, Discount, Surcharge, Tax, Custom).
- Pick calculation mode: Percentage or Fixed amount.
- Enter rate or net/gross amount; select a tax class if applicable.
- Set position to control ordering in totals (optional).
- Save with
Cmd/Ctrl + Enter;Escapecancels.

How adjustments roll into totals
- Each adjustment contributes to subtotals and grand totals based on kind and tax class.
- Shipping and surcharge entries increase totals; discounts reduce them; tax adjustments apply the selected rate or amounts.
- Order detail shows grouped totals (net, gross, discounts, surcharges, tax) for transparency.

Tips
- Predefine Adjustment kinds in Sales settings so operators pick from curated options.
- Use percentage for promos tied to the subtotal; use fixed amount for fees like “Stripe processing”.
- Keep tax classes aligned with your catalog pricing for consistent VAT handling.
