A chargeback comes straight out of your next payout, plus a fee. Win or lose. Measure gives you a more complete picture of your position.

Shopify and Stripe show you one rate for every card together. The card networks each measure differently. Measure measures your dispute rate for Visa, Mastercard, American Express and Discover every day. Beside each rate you see how much of your sales that card carries. Month by month, you see where your rate has been.
With the introduction of VAMP, Visa has lowered the dispute threshold from 2.2% to 1.5%. Shopify and Stripe judge you against their own standard, set below the published network rates.
Measure is free and shows your rate the day you connect.
