Settings: currency, tax, defaults and warnings

What every setting does, and which ones to change first.

Last reviewed 2026-11-13

Settings change how prices are shown and what every new calculation starts with. Set them once and you rarely come back.

Set up in four steps

  1. 1Your business: choose your store currency, decimals and how numbers are written. The Preview line shows the result.
  2. 2Pricing defaults: choose margin or mark-up and the profit you usually want. Choose a rounding, for example up to the next 0.50.
  3. 3Tax: type your VAT rate and tick the box if your shop prices already include VAT.
  4. 4Warnings: set the margin below which a price counts as thin. Then press Save settings.
Settings page with five cards: Your business, Pricing defaults, Tax, Warnings and start page, and Your data and account

What each one does

  • Margin is a share of the selling price. Mark-up is a share of your cost. A 25% margin is a 33% mark-up.
  • Rounding always goes up, so it never lowers your profit.
  • Minimum price: no price comes out lower than this.
  • Orders per month: monthly costs like rent are divided by this number in new calculations.
  • Thin margin below: prices earning less than this are amber on the Dashboard and in Catalog check.
  • Open this page first: choose what you see after signing in.

Tip. Changing settings does not change calculations you already saved.
