Stigg Buys Received.ai to Tie AI Usage Controls to the Invoice

Stigg has acquired Received.ai, extending a platform built to control what software customers can use into the work of translating contracts and metered usage into invoices. The pitch is not to replace a billing stack, but to connect the custom terms in a sales-led deal with the systems that enforce access and calculate charges.

The acquisition, announced August 18, brings usage-based invoicing and contract-management technology into Stigg. Stigg already provides pricing and entitlement infrastructure: tools that meter usage, manage credits and permissions, and enforce product and pricing rules in real time. An entitlement is the permission that defines what a customer, user, team or agent may do.

That puts access control beside a separate commercial task. The entitlement layer applies a customer’s access rules; contract management captures the deal terms, and invoicing turns them into charges. Stigg says the acquisition brings contract-to-invoice automation into the same platform as its usage controls.

From signed terms to invoice logic

The acquired functions cover the points where a custom contract has to become a working billing setup. Stigg says its contract-management feature can automatically provision entitlements when a deal closes, linking the access rules to the agreement sales signed.

What the acquired layer adds

• Billing schedules, prorations and credit handling that follow contract dates.
• Formula-based pricing, which calculates charges at invoice time from usage and other variables rather than hardcoding rates.
• Consolidated invoicing, which combines charges across multiple products or usage measures into one customer invoice.

Stigg’s central distinction is coexistence. Customers can retain Stripe, NetSuite, Airwallex, Checkout.com or other billing systems while enabling the added functions. The company describes those functions as additive and toggle-on; it also says existing product-led checkout flows are unchanged.

For a company without a payment-rails provider, Stigg says the expanded platform can handle the path from entitlements through invoicing. That is a different offer from adding contract and access-control functions around an established billing system.

The target is the exception-heavy deal

The case for that connection is strongest in customized enterprise deals. Stigg and Received.ai say software companies increasingly use pricing with usage thresholds, credits, prorated charges and mid-contract changes. Those terms can be difficult to translate into billing systems, leaving sales, finance and engineering teams to handle exceptions manually.

That separates a standard checkout from a negotiated arrangement. Stigg says a product-led flow can continue as before. The acquired layer is aimed at the changes after a sales-led contract is signed: different dates, credits, usage measures and amendments that must reach both access rules and the invoice.

The technology is fully integrated into Stigg, but the contract-management and invoicing functions are in public beta. That makes the immediate release an early-access product, rather than the completed general rollout Stigg has planned.

Shai Betito, Received.ai’s founder and CTO, has joined Stigg as vice president of engineering to lead the integration. Stigg plans broader general availability through 2026, leaving beta customers as the first users of the combined contract, entitlement and invoicing workflow.
