The checklist: descriptor match, delivery-expectation copy, alert enrollment, review-queue capacity plan, carrier cutoff calendar, return-policy refresh, fraud-rule tuning, evidence-capture audit, dispute-notification routing, and a fight/fold policy written down. Every item is a 30-minute fix in September and a crisis in November. Volume multiplies whatever posture you enter with.
Why September
BFCM math: 3–5x order volume → 3–5x dispute volume, arriving on the 90-day tail through February. Every weakness scales with it: a descriptor mismatch worth 5 disputes/month in September is worth 25 in December; a review queue that takes 30 minutes daily takes 3 hours.
And fixes deployed during peak are fixes deployed badly. The window for calm configuration is now — October is for tuning, November is for executing.
The ten items
- [Descriptor](/blog/payment-descriptor-optimization) = storefront brand. Five minutes; kills the unrecognized-charge class.
- Delivery estimates at checkout — with holiday-realistic dates, updated as carrier cutoffs approach.
- [Alert enrollment](/blog/chargeback-alerts-shopify-setup) — takes weeks to activate; start now to be live for November.
- Review-queue capacity plan — who reviews flagged orders at 4x volume? Decide before the queue backs up.
- Carrier cutoff calendar — 'order by Dec 18 for Christmas' copy staged and dated.
- [Return policy](/blog/shopify-returns-policy-chargeback-defense) refresh — extended holiday windows, prominently displayed (that display is dispute evidence).
- Fraud-rule tuning — Flow rules reviewed against this year's patterns, not last year's.
- Evidence-capture audit — order data, delivery confirmations, policy snapshots all flowing.
- Dispute-notification routing — alerts to a watched channel with a named owner and an SLA.
- Fight/fold policy written — thresholds decided calmly now, executed mechanically at volume.
Or compress items 3–10: Aurai automates detection, evidence, triage, and submission — installing it in September is the single largest line-item on this list.
Frequently asked questions
When do BFCM chargebacks actually arrive?
December through February — cardholders dispute up to 120 days post-charge. November's sales are Q1's dispute queue.
What's the single highest-ROI prep item?
Descriptor match if it's wrong (5 minutes, 30–45% of unrecognized-charge disputes). Otherwise alert enrollment — it has the longest activation lead time.
