The hidden cost

What this is really costing you

In the ecommerce industry, managers spend too much time calculating order costs by pulling product prices from Shopify, checking tax rates in Avalara, and estimating shipping with UPS calculators. Each order demands careful review and manual entry, leading to frequent mistakes and slow turnaround. This tedious workflow frustrates both staff and customers, especially during busy sales periods.
