Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Zoho Billing can take money outside a subscription — and is now deciding who may touch what.
The window splits three ways. Collection expanded first: hosted payment pages for individual items, shareable as a URL, QR code, iframe or HTML button, followed by a redesigned single-page checkout in early access with abandoned-cart recovery and saved progress. Reporting was cut along subscription-planning dimensions — active subscriptions by country and by product, plus a payment-method summary flagging cards near expiry. The newest thread is access control, with role-based permissions arriving on the SKU field in July and on extensions in August.

Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.

Two of these directions matter. Zoho Billing now collects for a single item outside any subscription, records the payment and raises the invoice, which puts it in reach of transactions it previously had no surface for. The access-control work points somewhere else: per-field and per-extension permissions are what a catalog shared by a larger team needs, not what a small biller asks for. Reporting by country, product and card expiry is groundwork for retention and dunning rather than accounting output.
Expect the redesigned checkout and item payment pages to leave early access and reach organizations created after the July cut-off, with role-based access continuing to spread field by field.
