Does TrueProfit let me set different supplier costs based on order quantity?

Yes. On the current COGS setup (Version 3), if your supplier charges less per unit at higher quantities (a common tiered-pricing structure), TrueProfit lets you enter each quantity tier's exact cost, so your COGS and net profit reflect the real cost, not a flat per-unit estimate.

For example, if your supplier quotes:

1 unit = $11.94

2 units = $19.78

3 units = $27.37

4 units = $36.40

You enter those tier costs once. TrueProfit automatically applies the largest matching bundle first on every order.

(a 45-unit order = ten 4-unit bundles + one 3-unit bundle + one 2-unit bundle).

See Set up cost of goods sold and bundle costs (Version 3) for setup.
