Fixed fees (also called Service Fees) are charges with a set price that are billed on a defined schedule or event, regardless of the amount of usage a customer has accumulated. In Vayu, fixed fees can be billed using four payment models: 
  • One-Time Fee
  • Subscription
  • Contract Terms
  • Commission

​
One-Time Fee

A One-Time Fee is a fixed, single charge, typically used for things like setup, onboarding, implementation, or an upfront service charge (a contract can include multiple one-time fees). One Time Fee Modification options on a One-Time Fee Products:
  • Pricing Settings
    • Credit Purchase
      When enabled, the one-time fee is treated as a prepaid credit purchase (the customer pays upfront to receive credits that can be applied to future charges).
    • Product Description
      A custom line-item description shown on the invoice to clarify what the fee is for.
    • Add Discount
      Apply a discount to the one-time fee amount by a specified fixed amount or a specified percentage (%).
  • Schedule
    • Custom Start Date
      Controls when this one-time fee is billed by setting a specific charge date for the fee instance. By default, the fee is billed on the contract start date.
    • Custom Date Range
  • Payment
    • Issue as Separate Invoice
      When enabled, this one-time fee is billed on its own invoice instead of being grouped with other products on the same invoice.

​
Subscription Pricing

A Subscription product is a fixed-fee product that generates a recurring charge on a defined billing interval (e.g., monthly, quarterly, yearly) for as long as the contract is active.
It is commonly used for ongoing service charges like platform fees or support plans. Click on Modify when creating the subscription plan so you can edit any default settings that you want.  Modification options on a One-Time Fee Products:
  • Pricing Settings
    • Product Description – A custom line-item description shown on the invoice to clarify what the fee is for.
    • Add Discount – Apply a discount to the subscription using a specified fixed amount or percentage (%). You can set how many recurring charges the discount applies to, or apply it to every subscription charge for the full duration of the subscription.
    • Add Seats – Adding seats will multiply the price according to the number of seats added. So, if the subscription price is $100 per month, and you add five seats, the monthly price will be $500. The number of seats can be adjusted throughout the contract’s lifecycle. Add Seats
  • Schedule
    • Period / Billing Interval – Period defines the time unit the subscription price applies to (e.g., a monthly price, quarterly price). Billing Interval defines how often Vayu generates the charge/invoice line for the subscription.

      Example: If the subscription is $100 per month (Period = Monthly) and you bill every quarter (Billing Interval = Quarterly), Vayu will generate one charge every 3 months for $300 (3 × $100). By default, Subscriptions are set for a monthly period & monthly billing interval
    • Contract Upfront – When enabled, Vayu charges for the entire contract term upfront (based on the subscription’s monthly price), overriding the standard period and billing interval behavior.
    • Custom Start Date – Controls when subscription billing begins by setting a specific start date for this product. Commonly used when billing should start after implementation is finalized or after a free trial period. By default, the subscription starts billing on the contract start date.
  • Payment
    • Issue as Separate Invoice – When enabled, each subscription charge is billed on its own invoice instead of being grouped with other products on the same invoice.

Commission

Designate a percentage of the total as a commission in your plan. Commission adds an extra percentage on top of the final invoice total.
