Why Teams Switch from Tabs to Vayu

Tabs bills from contracts. Vayu bills from real activity.

Problem

Tabs reads the contract and generates invoices based on legal terms, not operational delivery.

Why it matters

Works for static SaaS, breaks for usage-based, API-based, or volume-based revenue.

Vayu solves it

Connects to your systems (databases, APIs, logs) and bills based on what actually happened in real time.

Tabs requires CRM/ERP as the data source

Problem

Tabs depends on Salesforce / HubSpot / Netsuite fields, not product or usage systems.

Impact

Finance can’t see real consumption, margin, or delivery in one place.

Vayu solves it

Directly ingests usage + delivery data, eliminating spreadsheets and manual reconciliation.

Usage billing is add-on only, not native

Tabs

Tabs supports usage only through Stripe-based integration or custom mapping.

Vayu

Vayu is built for 1M+ usage events per day- API calls, compute, storage, datasets, seats, or entitlement tiers.

Tabs automates invoicing. Vayu automates the full revenue lifecycle.

Tabs

Tabs = contract ingestion → invoice creation

Vayu

Vayu = pricing → metering → billing → rev rec → forecasting → margin analytics (in one platform)
