Auditors ranked for e-commerce companies that typically face SOC 2 plus PCI DSS overlap (cardholder data environment), seasonal audit timelines, and Shopify / Stripe / payment-processor integrations.
How we picked: Auditors ranked for e-commerce companies that typically face SOC 2 plus PCI DSS overlap (cardholder data environment), seasonal audit timelines, and Shopify / Stripe / payment-processor integrations.
We filtered for AICPA-licensed firms that hold PCI QSA accreditation OR have documented PCI DSS service capability, since e-commerce companies almost always need both. Peer review status had to be pass or unknown (per AICPA enrollment requirement). We considered fixed-fee availability because e-commerce companies often have unpredictable peak-season cash flow.

Sensiba is AICPA peer-reviewed and serves mid-market but does not hold PCI QSA in the directory data, so e-commerce buyers needing a combined PCI + SOC 2 engagement would have to engage a separate QSA. Prescient Assurance has cybersecurity capability but is not listed with PCI QSA accreditation. KPMG and other Big 4 are out of price band for most independent e-commerce brands.
