Usage-based billing software

Invoicing for consumption-based pricing models


Automate the usage-based billing lifecycle

From consumption to collection.

Data mediation

Stream, batch, or upload metered consumption data. Share pre-rated, partially rated, or unrated files. Process aggregate blocks or discrete units.

Rating engine

Compute charges for flat-rate, volume, tiered, and stair step billing models. Combine with flat-rate subscriptions, percentage billing, and one-time charges.

Overages & allowances

Calculate overage charges for excess usage above subscription allowances. Automate rollovers of credits and track expiration dates.

Pre-paid usage

Manage drawdowns and replenishment of prepaid credits. Track progress towards contract spend commitments and calculate true-ups.

Detailed invoices

Display formulas, calculations, and rating tables for usage calculations on invoices. Enable downloads of usage detail records.

Multi-dimensional rating engine

Ordway’s rating engine supports all the popular discounting models as well as hybrid combinations of usage-based pricing with tiered subscriptions and percentage (commission) pricing models.

Single rate

Apply flat rates to usage for linear pricing models

Example: The customer is billed $0.50 per transaction whether they performed 1 transaction or 1 million transactions.


Apply dynamic volume discounts based upon usage.

Example: The customer is billed if $1/unit if volume is below 1000. Above 1000, all units from 1 to n are billed at a discounted rate ($0.50).


Compute charges at multiple rates for multiple tiers.

Example: The customer is billed $1 for the first 1000 units consumed, $0.50 for the next 1000 units, and $0.25 for any additional units.

Stair step

Tiered packages – each with a max allowance.

Example: Package A includes 500 units for $100/month. Customers of package A are billed $100/month whether they use 0, 250, or 500 units.

Contract structures

Convert month-to-month customers into long-term contracts


Attract new customers with low risk and low cost entry point models that allow them to realize the value of your offering.

  • Freemium and free trials: Offer 30, 60, or 90 day free trials that auto-convert into paid plans. Or limited feature, free forever plans with usage caps.
  • Pay-as-you-go: No commitment plan in which the customer pays only for what they consume each month with the option to cancel at any time.


Convert month-to-month customers into long-term contracts with predictable revenue models that are more like recurring.

  • Prepaid usage: Pay in advance for a fixed number of units or dollar value of services. Automated or sales assisted replenishment as needed.
  • Subscription: Packaged offering that allows usage within a certain volume range or up to a certain maximum in exchange for a monthly fee.


Grow customer revenues with enterprise contracts that allow multiple teams to use multiple products across the account.

  • Monthly minimums: Spend either 1) actual fee based upon usage or 2) a minimum dollar amount per month in exchange for a discount.
  • Spend commitments: Achieve a certain spend threshold per year in exchange for discount. True up payment is owed if commit not realized.

Prepaid credits with drawdowns and replenishment

Convert pay-as-you-go customers into long-term contracts with recurring revenue by offering prepaid usage options.

Drawdowns: Track revolving balance of vendor-issued and customer prepaid credits. Debit based upon actual consumption month-to-month.
Replenishment: Create workflows to auto-replenish pre-paid credits based upon triggers or thresholds. Alternatively, notify customers for approvals.
Usage pooling: Allow customers to apply credits to usage across their multiple business units and your various product offerings.

Spend commitments

Offer volume discounts to customers in exchange for spend commitments to incentivize greater adoption of usage-based products:

Cumulative spend

Track the aggregate spend (and usage) on eligible products on a quarterly, annual or contract term basis.

Remaining obligations

Calculate remaining balance based upon contract obligations and historical billings across various products and departments.

True up calculations

Determine amounts owed by customers for spend deficits. Perform true up calculations on monthly, quarterly, or annual basis.

Usage allowances, rollovers, and overages

Offer customers with lower consumption the flexibility to rollover credits to future periods. Monetize excess usage with overage charges.


Support pricing models with allowances for a certain number of units or transactions per month as part of a fixed fee package.


Manage rollover units along with the any associated usage caps, policies, and expiration dates.


Calculate charges for overages based upon pre-negotiated discounts, standard price lists, or by applying premium surcharges.
