Avalara timeout masks express pay

When tax quote latency exceeds 920ms, the checkout template hides accelerated payment buttons. Mobile paid social traffic abandons at 18.4% above baseline.

Ready: select an issue or run sample trace.

Built for teams that already know checkout is a system.

The sprint produces evidence your designer, ecommerce lead, and engineering team can all act on without debating whether the bug is real.

One sprint, four hard outputs.

CartCaliber is sold as a productized service because checkout diagnosis fails when scope keeps expanding. The boundary is strict: one primary purchase path, measured deeply.

01

Instrument

We add a temporary trace layer to capture client errors, latency, route changes, discount state, and third-party script timing.

02

Replay

We reproduce failure paths with real catalog rules: tax zones, coupon stacking, inventory holds, wallet payments, and consent states.

03

Rank

Every issue is scored by recoverable revenue, implementation risk, and dependency owner so the queue is easy to sequence.

04

Handoff

Your team receives tickets, test cases, trace evidence, and a launch checklist for the first patch release.

Reserve a checkout trace sprint.

Start with the fit check below. The button intentionally stays disabled until the minimum operational details are present.
