Most small and mid-size shippers pay list price because carrier discounts are negotiated on volume they don't have. InsertReady rate-shops every parcel across USPS, UPS and FedEx on our accounts, so you get the discounted rate without the contract, the commitment, or the monthly minimum.
There is no trick to it. Carriers price on volume, and volume is something a platform can aggregate but a single shipper cannot.
Your shipments move on InsertReady's carrier accounts, which are priced on the combined volume of every business on the platform — not on yours alone.
Each shipment is priced across USPS, UPS and FedEx at the moment you create it. You see the real options side by side and pick, rather than defaulting to one carrier out of habit.
No monthly volume commitment, no negotiated-rate agreement to sign, and no penalty for a slow month. Ship one parcel or ten thousand.
It depends on the parcel — which is exactly why rate shopping saves money. There is no single carrier that wins every package.
| Carrier | Usually best for | Watch out for |
|---|---|---|
| USPS | Lightweight parcels under about 5 lb, residential delivery, PO boxes, and Flat Rate when the box is dense. | Weight-based pricing climbs quickly past 5 lb; limited liability without added insurance. |
| UPS | Heavier and higher-value parcels, commercial addresses, and predictable ground transit times. | Residential and delivery-area surcharges add up on consumer shipments. |
| FedEx | Time-definite air, larger dimensional parcels, and lanes where its ground network is strong. | Dimensional weight is applied aggressively — an oversized light box prices as a heavy one. |
The estimator above prices your parcel against all three at once using live carrier rates, so you can see the spread rather than guess at it.
No. InsertReady has no volume minimum and no monthly commitment. Your parcels move on our carrier accounts, so the pricing comes from the platform's aggregate volume rather than yours.
Rate shopping means pricing the same parcel across multiple carriers at the moment you ship it, then choosing the best option. Because no carrier is cheapest for every package — weight, dimensions, destination and residential status all move the price — comparing on every shipment captures savings that picking one carrier cannot.
USPS, UPS and FedEx are rated live on every parcel. You see each carrier's services and prices side by side before you buy a label.
No. You can ship entirely on InsertReady's accounts. If you already have negotiated carrier rates of your own, you can connect those accounts as well and rate-shop your own pricing alongside ours.
No. The estimator returns a modelled comparison for planning only. Final pricing depends on your account, the accessorials you select, carrier surcharges, and the audited weight and dimensions of the piece as measured by the carrier.
Usually dimensional weight or an accessorial. Carriers bill on whichever is greater, actual weight or a volume-derived dimensional weight, and add charges for residential delivery, address correction, signatures and remote areas. Rating on accurate dimensions up front avoids most of the surprise.
