Understanding Charge Types
When adding additional costs to an invoice, you can choose from three primary calculation methods: Percentage, Fixed Flat Fee, or Per Quantity.1. Percentage Charges
Calculated as a portion of the total invoice value.Best for: Taxes, service fees, or insurance.Example: A 10% service fee on a $500 invoice adds $50.2. Fixed Amount Charges
A set price that stays the same regardless of the invoice total or item count.Best for: Flat-rate delivery, processing fees, or administrative fees.Example: A flat $50 "Standard Shipping" fee applied to the whole order.3. Per Quantity Charges
Calculated by multiplying a set rate by the number of units/items on the invoice line.Best for: Installation fees per item, disposal fees, or per-unit packaging costs.Example: A $5 "Eco-Tax" applied to 10 separate items results in a $50 charge.
Minimum Amount Limit
- This sets a floor for the charge amount.- If the calculated charge is below this minimum amount, the charge will be set to the minimum amount.- For instance, if the minimum charge amount is $5 and the calculated charge is $3, the charge will be adjusted to $5.Maximum Amount Limit
- This sets a ceiling for the charge amount.- If the calculated charge exceeds this maximum amount, the charge will be capped at the maximum amount.- For example, if the maximum charge amount is $10 and the calculated charge is $15, the charge will be capped at $10.
