Payments Weekly Status

Week of Oct 12 to Oct 16, 2026

Priya Raman, Engineering Manager, Payments

Five of seven sprint commitments shipped and authorization success hit a six-week high. Two items slipped: EU acquirer routing (blocked on partner certificates) and ledger reconciliation v2. The chargeback rate is above its 0.50% ceiling for the second week running, and that is the risk I most want your attention on.

Decisions needed from you

  1. A call to the acquirer's regional head by Oct 21 to ask for priority on the EU certificates. This is the only thing that protects the Nov 1 pilot date.
  2. Approval for one contractor for 6 weeks ($38,000) to cover Mei's absence and the ledger v2 backlog.
  3. Agreement that if chargebacks reach 0.65% before Oct 30, we pause new-merchant onboarding until the rate is back under 0.55%.
