The Amazon FBM shipping problem

Amazon FBM sellers are penalized for late tracking submissions and high defect rates. Most shipping software makes you manually upload tracking, which introduces delays and errors. And if you're only using USPS, you're absorbing every rate hike without the ability to route to a cheaper carrier.

What LogixVast does for amazon fbm sellers.

Native Buy Shipping API

Orders sync directly from Amazon Seller Central. No CSV, no plugin. Tracking uploads back to Amazon the moment a label is generated.

Multi-carrier rate shopping

For every FBM order, LogixVast compares USPS Ground Advantage, UPS Ground, FedEx Home Delivery, and DHL simultaneously. The cheapest route is highlighted.

Free BYOCA

Bring your own negotiated FedEx or UPS account. Use your volume-discounted rates through LogixVast — free on every plan.

Seller metric protection

Late dispatch rate, tracking rate, and valid tracking rate are all maintained automatically. No manual tracking uploads means no submission errors.

Multi-channel if you sell elsewhere

Add Etsy, Shopify, TikTok Shop, or Walmart alongside Amazon. All orders in one queue, one rate comparison engine.

Exception alerts

When a shipment stalls or a carrier scan goes missing, you're notified before Amazon's A-to-Z clock expires.

Up and shipping in 10 minutes.
