The system
How do I get started?
Click Start now to create your ERP.AI account, then use Proto to configure Subscription Billing. Bring your accepted plans, customer accounts, meter definitions, billing review process and payment connections.
What happens when the same usage event arrives twice?
An identical source event identity and payload returns its earlier accepted result. The quantity is not added again. A changed payload under the same identity becomes a conflict for investigation.
Does a successful payment request mean the invoice is paid?
The provider outcome must be verified. Pending, authorised and unknown attempts remain separate from settled receipts. A timeout keeps the original instruction identity until reconciliation prevents an accidental second charge.
Will dunning cancel a subscription automatically?
A dunning stage records collection follow-up. A service change requires the accepted subscription policy and an explicit authorised lifecycle transition. Sending a reminder alone does not cancel the agreement.
Processes and approvals
How do you handle late usage?
The billing candidate records its occurrence-time interval and receipt cutoff. Late accepted usage can enter an unissued replacement candidate or a reviewed adjustment for an already issued interval, preserving the earlier invoice.
Does this calculate recognised revenue?
The app reports accepted recurring commitments, issued billing and actual collection on a stated basis. Revenue recognition and general-ledger posting belong to the configured accounting system and its approved policies.
Pricing and implementation
Can plans combine a recurring fee and metered usage?
A published plan can define its base amount and an explicit contracted or metered quantity basis. The accepted allowance, aggregation and pricing mode determine how the variable amount is calculated.
What is the difference between graduated and volume pricing?
Graduated pricing rates the units in each used band. Volume pricing selects a band from total billable quantity and applies that band’s configured rate to the quantity. Published tier boundaries and examples make the calculation reviewable.
Can customers change plans during a billing period?
Accepted changes retain an effective instant and both sets of terms. A plan with actual-seconds proration shows the old unused credit and new remaining charge separately; a no-proration plan follows its accepted rule.
Can we correct an invoice after it is sent?
Preserve the issued document and independently review the difference from its corrected source. An undercharge can produce a linked correction invoice or later billing line; an overcharge produces credits tied to the actual remaining billed line amounts. If cash needs to be returned, a separate refund request retains its own approval and observed provider outcome.
