How do we stop tax-exempt wholesale, school, and nonprofit orders from getting charged sales tax by mistake in Shopify and QuickBooks?
Aria operates a Google Cloud Run tax-exemption bridge (`fundraiser-blankets-api`) that validates 50-state resale and 501(c)(3)/school exemption certificates at checkout in under 120ms, blocks erroneous tax collection automatically, and stages draft QuickBooks Online ledger adjustments for controller signoff.
