Why isn’t the price list applying the correct price to the invoice?

There are several common reasons the expected price might not appear on an invoice line:

If the price list is of the quantity pricing type:

• Make sure the quantity entered on the invoice line equals or exceeds the start quantity of the desired tier, since the system only applies the price of the tier the actual quantity falls into, not any other tier.
• If the quantity is lower than the smallest start quantity defined in the list, no quantity tier price will be applied at all.
• Check that the same start quantity for the same product hasn’t been entered with different prices — if it has, the last saved price for that quantity takes effect, which may not be the intended one.
• Verify that the client or invoice is actually linked to the correct price list that contains these tiers.

If the price list is of the unit pricing type:

• Make sure the product is actually added as an item in that list; if it isn’t, the product’s default price will be used instead of the list price.

In general:

• Remember that a single price list cannot combine unit pricing and quantity pricing — if you try to add an item with a pricing type different from the list’s type, it will be rejected or ignored.
• If you recently imported pricing data, check that the import matched records correctly based on product code and start quantity; if the start quantity differs from what was intended, a new price entry may have been added instead of updating the existing one.

If you’ve checked all of the above and the price is still incorrect, it’s recommended to review the price list’s item listing directly to verify the values actually saved.
