What is Shift4?
Shift4 starts its Q4 venue rollout in canary while Customer Hub adds enterprise modifiers.
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R1 reached canary venues on October 20, with global release planned for October 27. Customer Hub 2026w43 lets operators promote modifiers to the Enterprise level.
What is Stigg?
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.

Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Shift4 vs Stigg: editorial side-by-side
Shift4
5.0FINANCE
Shift4 starts its Q4 venue rollout in canary while Customer Hub adds enterprise modifiers.
◆ Current state
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R1 reached canary venues on October 20, with global release planned for October 27. Customer Hub 2026w43 lets operators promote modifiers to the Enterprise level.
◆ Where it's heading
The cadence is steady and staged: quarterly venue bundles go canary, then global, then get patches, while Customer Hub ships weekly. Recent Customer Hub builds lean toward multi-location and enterprise management, including Payment Links for Opera and now enterprise-level modifiers. The feed truncates most details, which limits how far this can be read.
◆ Prediction
Q4-R1 should go global around October 27, followed by a patch about a week later as in Q3. The specific features are not visible in the truncated notes.
Stigg
6.3FINANCE
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
