ShuntflowWhat it watches
Chargebacks
Share of orders that end in a chargeback over the last 30 days, the signal card networks monitor most closely.
Refunds
Amount refunded over amount sold. A high, sustained rate usually points to delivery, quality or description problems.
Order value and volume spikes
Sudden jumps compared with the previous 30 days, a pattern often seen around fraud and viral campaigns.
International payments
How your mix of billing countries shifts from what is usual for your store.
How it helps
Alerts only when something changes
You hear from Shuntflow when a signal moves between levels — including when it improves — so every alert is worth reading.
Email alerts
On the Pro plan, one email per analysis with every change, the figures behind it and a link to the app.
Appeal dossier
A checklist of the documentation payment providers commonly ask for, with your own notes, ready before you need it.
Who it is for
Shopify merchants who want to keep an eye on the numbers that payment providers care about: growing stores, stores running big campaigns, dropshipping and pre-order businesses, and anyone who has had funds held before and would rather not go through it again. Chargeback monitoring needs Shopify Payments; every other signal works with any payment provider.
What it is not
Shuntflow monitors publicly known risk factors and does not represent or replace Shopify Payments' actual risk assessment. Alerts are for guidance only and neither guarantee nor predict the platform's decisions.
