Shipping Rate Automation & Carrier Integration
Last Updated: Mar 13, 2026
Manual shipping rate management creates three expensive problems. Your team spends 3-5 hours per week manually calculating rates adjusting orders and fixing pricing errors. Undercharging for shipping costs you money on every order - even $2-3 per order adds up to thousands in lost margin while overcharging kills conversions. Customers confused about shipping costs flood your support team with questions. Most Shopify stores try to solve this with apps like ShipperHQ ($50-300/month just for rates) or custom development ($10,000-50,000 to build). Both approaches are expensive and don't include delivery date selection. Flare automates shipping rate calculation AND delivery date selection in one app for $39-599/month - giving you complete checkout automation at a fraction of the cost.
How Flare Solves It.
