The shipping cost squeeze#
For a US e-commerce seller doing $500,000 in annual revenue, shipping typically represents $75,000-100,000 — the second largest cost after inventory. Carrier rates increased 5.9 percent on average in 2025 (UPS and FedEx general rate increases), and dimensional weight pricing means oversized packaging is now more expensive than ever. Yet most small sellers ship on a single carrier's default rates without comparing options per package.
How AskBiz optimises shipping#
Upload your shipping history (tracking data, carrier invoices, or platform export). AskBiz analyses every shipment across three dimensions: rate comparison (would UPS, FedEx, or USPS have been cheaper for each specific shipment based on weight, dimensions, and destination zone?), packaging analysis (are you using boxes that trigger dimensional weight surcharges when a smaller package would work?), and zone distribution (where are most of your customers, and would a second fulfillment location reduce average zone and transit time?).
Real scenario: an Etsy seller in Oregon#
Rachel sells handmade candles on Etsy, shipping 400 orders per month. She used USPS Priority Mail for everything because it was 'easiest.' After uploading her shipping data to AskBiz, the analysis showed: 35 percent of her orders (lightweight, close zones) would be cheaper via USPS Ground Advantage at $3.20 less per package, her 8x8x8 boxes triggered dimensional weight for candle sets that would fit in a 6x6x6 (saving $1.80 per shipment), and 42 percent of her orders went to East Coast zones 7-8 — suggesting a fulfillment partner in the Midwest could cut those shipments from $12.40 to $8.60 average. Total annual savings identified: $18,200.

Carrier negotiation leverage#
AskBiz shows your shipping volume breakdown in a format you can present to carrier reps when negotiating discounted rates. Knowing your exact volume, average weight, and zone distribution gives you leverage most small sellers lack.
Free shipping math#
'Free shipping' is never free — you pay for it. AskBiz calculates exactly how much free shipping costs you per order and helps you set the minimum order threshold that makes free shipping profitable rather than margin-destroying.
