Setting prices and margins

Last checked Wed, Oct 7, 2026

Once Works knows what a product costs, it helps you decide what to charge, and shows what each product really earns.

Your target margin

In Settings › Edit settings, the Target gross margin is the share of the price (before tax) you want to keep as profit. Works suggests a price for every product that reaches it. A 40% target on a $9 cost suggests $15: $6 of profit is 40% of $15.

A product's price

A product's price is its Retail price (MSRP): one unit, before tax. Tax is added on top. Set it on the product's Selling card (on its Details or Pricing tab) with Edit.

The Pricing tab shows:

  • Cost per unit,
  • Retail (MSRP), before tax and with your taxes,
  • Profit each, and per print hour,
  • Margin, next to your target.

The price calculator

Also on the Pricing tab. Type into any box and the others follow:

  • Markup %: profit ÷ cost,
  • Margin %: profit ÷ price before tax,
  • Profit: a flat amount on top of cost,
  • Price before tax, or
  • Price with tax. To land on a round price with tax (say $20.00), type it in the last box.

The calculator doesn't save anything. When you've found your price, set it in Selling.

Which products earn the most

Under Sales › Products, switch from By category to Ranked, then rank by:

  • Profit per print hour: what to put on a free printer,
  • Profit per 100 g: what makes the most of your filament,
  • Profit each, or Margin.

Products ranked by profit per print hour

A small, quick print can earn far more per hour than a big one with a higher price. In the demo, a $1.50 cable clip earns more per print hour than a $24 planter.

Small jobs and rush jobs

  • Minimum job charge (Settings): small orders are topped up to it automatically.
  • Rush fee (Settings): a percentage added when you tick Rush in Quick job.
