Billing that stays aligned when your usage shifts

BirdyFoot turns metered events into billable line items. You can pass through provider cost, apply margin rules, and generate records your finance team won’t argue with.

Built for
B2B SaaS billing flows
Outputs
Invoices and exports
Controls
Entitlements and limits

Capabilities

Billing is more than invoices

It is pricing logic, entitlements, enforcement, and records that survive month-end.

Invoice
capability

Invoices from usage events

Turn normalized usage into line items with a clear mapping back to customer, SKU, and service.

Plans
capability

Tiers, bundles, overages

Included usage, overage pricing, and feature-based SKUs without spreadsheets that rot.

Pricing
capability

Pass-through, markup, blended margin

Choose how provider costs flow through, then apply explicit margin rules per unit.

Exports
capability

Exports that finance can use

Warehouse feeds, billing stack exports, and reconciliation-ready outputs with a source-of-truth ledger.

Pricing model surface

Keep units consistent across providers

The point is not to invent a new billing unit. The point is to normalize provider units into a stable event schema so your pricing stays sane as infrastructure shifts.

Accuracy

No mystery rollups

Line items trace to raw usage events, with explicit pricing rules.

Control

Entitlements by plan

Limits, alerts, and overage behavior tied to the same underlying units.

Billable units
Tokens
input and output tokens, model variants, per-SKU pricing rules
Vector
queries, writes, deletes normalized across stores
Storage
GB-month, retention bands, egress signals
Compute and tools
internal SKUs alongside AI usage for full unit economics
Bundles
included usage with consistent overage units

Workflow

A billing pipeline that stays legible

Different layout from metering: a horizontal rail instead of cards.

Turn usage into invoices without losing the trail

Billing should not be a disconnected spreadsheet. Keep usage, pricing rules, and invoices linked.
