Delino uses a transparent, credit-based billing system for payment processing. This guide covers subscription tiers, billing cycles, and how credits work.

​
Billing System

​
Credit-Based Model

Delino uses a credit system for precise usage tracking:
​
Conversion Rate
number
$1 USD = 1,000,000 creditsAll internal calculations use credits for precision, with conversion to USD only at invoice generation.
Examples: 
$0.001 USD = 1,000 credits
$0.01 USD = 10,000 credits
$0.10 USD = 100,000 credits
$1.00 USD = 1,000,000 credits
$10.00 USD = 10,000,000 credits

​
Why Credits?

Credits allow for sub-cent pricing without floating-point errorsExample: 150 credits = $0.00015 USD (precise to 6 decimals)
Integer arithmetic is faster and more reliable than decimal calculationsAll database operations use bigint for credits
No rounding errors or currency conversion issuesCredits are the single source of truth for billing
