The following outlines the different use.

Please be aware
Due to support of underlying finance systems (ERP), Upodi will handle all decimals when calculating tier and volume pricing, by supplementing quantity with 1 x the calculated price and adding the full quantity of this to the invoice line. ERP systems often calculate pricing of amount x quantity price, rendering the full amount wrong if decimals becomes larger than 2.
### **Flat-fee**
A _flat fee_ pricing model bills a subscription a fixed amount in the term of the subscription. Flat fee pricing models ignore the quantity of the subscription charge, however, a subscription charge quantity of 0 will ignore the fee in a billing cycle.
Flat fee pricing models are usually used for sign-up fees, cancellation fees and based level subscription fees.
### **Per-unit**
A per-unit pricing model, multiplies the per-unit amount with the quantity of a subscription charge. The following formular is used
Per unit fees are often used in SaaS subscription plans (per user) or mobile data plans (per gb data).
### **Tiered pricing**
A tiered pricing model offers a flexible billing based on the quantity amount of a subscription. A tiered pricing model is calculated based on the quantity tier and type of that tier multiplying each tier of the full quantity.

Each tier can be charged by _per-unit pricing_ level (see above), or a _[Flat fee](🔗)_ level (see above).
#### Example:
A tiered pricing model is calculated by the sum of all tiers matching the volume. Let's try to define this by looking at a sample table.
Tier | Pricing level | Pricing | Range |
A | Per-unit | $20 per unit | 1-100 |
B | Per-unit | $15 per unit | 101-200 |
C | Per-unit | $10 per unit | 201-300 |
A tiered pricing model for a quantity of 130, will sample calculation of _tier A_ plus _tier B_ but not _tier C_. Calculation is done as follows:
### **Volume pricing**
A volume pricing is often called a "discount ladder". A volume pricing models looks for a given tier of the volume pricing model, and calculates the total quantity of this tier.
#### Example
Using the sample table from above (tiered pricing), a volume pricing model, calculated with a quantity of 130, is done as follows. 130 matches tier B:
### **Procentage total**
Upodi only support one _Procentage total_ pricing model per product plan. In addition, the _Procentage total_ pricing model, is the last pricing model to be calculated on if present.
The calculation of this pricing model, is done as a procentage of total, of all previous charges summed together. Hence the name.
The _Procentage total_ pricing model, can be used to apply credit card (i.e. 0.5%) feeds or typed discounts onto a product plan.
