Billing & Contract Modifications

Billing Built for
Constant Change.

Your customers upgrade mid-month, add seats on a Tuesday, and switch models in Q3. GAAPX.ai handles every permutation without a single manual journal entry or broken invoice.

Supported Models

Every billing model. One platform.

The Hard Problem

Mid-Cycle Modifications.
Without the chaos.

When Acme Corp upgrades from a flat $2,500/month plan to usage-based billing on day 14, most platforms either break the invoice or require a manual credit memo. GAAPX.ai handles it in real time.

01

Amendment Detected

Salesforce CPQ sends an amendment event: Acme Corp upgrades from Flat Fee $2,500/mo to Usage-Based on day 14 of 30.

02

Pro-Rata Credit Calculated

GAAPX.ai computes credit for unused days: $2,500 × (16/30) = $1,333.33 credit applied to next invoice.

03

Usage Meter Activated

API call counter starts from day 14. 847,200 calls × $0.008 = $6,777.60 billed for remainder of month.

04

Invoice Reconciled

Net invoice: $6,777.60 − $1,333.33 = $5,444.27. Zero manual intervention. ASC 606 schedules updated automatically.

Native Salesforce CPQ Sync

In the CRM means no billing errors.

External billing systems require integrations. Integrations require maintenance. Maintenance fails. Being native eliminates the category of failure.

Zero-Lag Sync

Contract changes in CPQ propagate to billing in real time — no nightly batch jobs, no Monday morning surprises.

Single Opportunity ID

Every invoice traces back to a single Salesforce Opportunity ID. One click from CFO report to signed contract.

Override Protection

GAAPX.ai validates every invoice against the CPQ order. Manual overrides require a four-eyes approval workflow.

Ramp & Commit Support

Multi-year ramp deals, minimum commits, and true-ups handled natively without custom code or spreadsheets.
