Automating E-commerce Order Fulfillment - 85% Time Reduction and 99.7% Accuracy

An e-commerce company was drowning in manual order processing. With 2,000 daily orders across multiple sales channels, their team of 12 spent 8+ hours daily on repetitive data entry, inventory updates, and shipping label generation. Errors were costing $50,000 monthly in returns and re-shipments. Six months after implementing our automation solution, they're processing 10,000+ orders daily with 99.7% accuracy and a team of just 3.

Client Testimonial

"This automation transformed our entire business. We went from dreading order surges to actively seeking them. What used to take 12 people can now be managed by 3, with higher accuracy and customer satisfaction. The best part? We're now accepting wholesale contracts we had to reject before. The ROI paid for itself in 4 months, and we've scaled 5x without hiring a single additional fulfillment staff member."
