Pirate Ship compares USPS and UPS only; GoatLabels quotes UPS and FedEx on every domestic parcel, and USPS up to 70 lb, with DHL on international lanes, so the cheapest option wins even when it's FedEx.
USPS up to 70 lb; DHL joins on international lanes. The winner is decided per parcel, not per account.
Card, Apple Pay, Google Pay, ACH, or crypto — one prepaid balance behind every carrier.
Rate shopping has two variables: how good each carrier's price is, and how many carriers you are allowed to ask. Most comparisons obsess over the first. The second is what actually caps your savings, because a carrier that is not in the list wins zero parcels no matter how well it would have priced them.
| GoatLabels | Pirate Ship | |
|---|---|---|
| Carriers quoted per parcel | USPS (up to 70 lb), UPS and FedEx on domestic parcels at the same time; DHL joins on international lanes. | Two: USPS and UPS (pirateship.com/rates, checked 2026-10-23). |
| How the winner is chosen | Per parcel. Weight, size, and destination re-decide it every time. | Per parcel too — from a shorter list of candidates. |
| Bulky, low-density parcels | A dimensional-weight answer from each carrier to compare. | Two answers, both from the platform's carriers. |
| Express and time-definite | Includes the two carriers whose networks compete hardest on speed. | Whatever USPS and UPS offer for that lane. |
| What the number means | One all-in price per carrier, and that exact amount leaves your prepaid balance. | Their rates — check their current site. |
| Cost of running the comparison | None. No monthly fee on Free (up to 50 shipments a month), and unlimited free API calls to rate anything. | Also no subscription: the model worth keeping. |

A light parcel in a big box is billed on the space it takes up, and carriers apply that math differently. This is the single most common case where the carrier that wins your small parcels loses your bulky ones, and you only find out by asking every carrier.
Price steps up by zone, and the steps are not the same shape for every carrier. A parcel crossing the country can flip to a different winner than the identical parcel going two states over, which is why the comparison has to re-run per parcel rather than per account.
The moment a buyer needs a date, the candidate set changes: economy services drop out and the express networks compete. That is a different contest with a different winner, and running it with half the carriers missing is how you overpay for speed.

The mechanic is simple and it runs on every order regardless of how the order arrived. Weight, dimensions, and destination go in; USPS, UPS and FedEx are priced for that exact parcel (DHL too on international lanes); and the all-in numbers come back sorted, each one being precisely what will leave your prepaid wallet if you buy it. Nothing is locked to an account-level carrier choice, so a bulky box and a padded mailer packed the same afternoon can go out on different carriers without anyone deciding a policy. Orders can arrive by store sync, by API call, or as a pasted DM or screenshot that Billy reads into a draft, and the comparison is identical in all three paths.

No monthly fee on Free, up to 50 shipments a month. The comparison re-runs on the next parcel from scratch.
Shopify, Etsy, WooCommerce, eBay and Wix sync into To Ship and push tracking back when you print. A pasted DM or a screenshot goes through Billy instead. Either way the parcel gets the same carrier comparison before anything is bought.
The subscription-free model stays on Free, up to 50 shipments a month. What changes is how many carriers get to compete for each parcel — and around that, a wallet that shows one honest number, AI drafting, and an API that can run the same comparison from your code.
Card, Apple Pay, Google Pay, ACH bank transfer, and crypto all top up the same balance, and whichever carrier wins is debited from it. Void a shipment and, after the carrier accepts the void, the credit lands back in the wallet.
A DM, a comment thread, a voice note, a screenshot: Billy reads any of them and drafts the parcel details that drive the price, then runs the carrier comparison and preselects the winner.

Quotes are free on both plans, so running comparisons never costs anything. Free has no monthly fee for up to 50 shipments a month; past that, Pro is one flat $40 monthly plan with unlimited shipments, and a shipping review compares your current rates with ours on your real parcels.
USPS, UPS and FedEx priced on the same domestic parcel as live all-in numbers, DHL added on international lanes, and the one you pick is the exact amount that leaves your balance. The point is not that any one of them is always cheapest, it is that which one wins changes with weight, size, zone, and deadline, so the only way to be right consistently is to ask every carrier every time. Shopify, Etsy, WooCommerce, eBay and Wix sync into To Ship and get tracking pushed back when you print, but a connector is never a prerequisite.
REST and JSON, one Bearer header, idempotency keys so a retry cannot double-buy a label, and signed webhooks for tracking and label events instead of polling. One rate call returns every carrier that serves the parcel, so your backend can pick the winner too.
Label ready
CL-1038 · Brooklyn, NY
Nobody compares carriers by hand at a packing table, which is precisely why the savings go uncollected. The phone runs the comparison, shows the spread, and buys the winner from your prepaid balance in the same tap.
Say the parcel out loud: where it is going, roughly how big, how fast it needs to be there. Billy prices it across USPS, UPS and FedEx (DHL on international lanes), tells you which one won and what the runner-up would have cost, and queues the label against your prepaid balance. This is the real product, not a render.

Plain English in: names, addresses, weights, carriers, services · every eligible carrier priced · reads the all-in rate back before a cent leaves the wallet · phone, browser, or Telegram on Pro.
One parcel priced by more than one carrier at once, each an all-in number that is exactly what leaves your prepaid balance. That spread is the entire argument for rate shopping — and it is invisible if the carrier that would have won is not on the list.

Pro is a flat monthly fee for unlimited shipments. Neither is a minimum you have to hit before a label prints.

High-volume shippers can ask about custom pricing, which we review account by account. Compare it against what you pay on
ShippoPirate ShipShipStationLabel prices are quoted live from USPS, UPS and FedEx on domestic parcels and DHL on international lanes, shown as one all-in number — the same number that leaves your wallet. Pirate Ship's rates move, so compare against their current site rather than a figure on ours. Full pricing details
Uniform parcels going short distances rarely change winners. Variety is what makes the comparison worth running — different sizes, different zones, different deadlines.
TikTok Shop & live commerce
A drop ships mailers and boxes in the same night to every zone at once. That is the maximum-variance case, and it is exactly where a two-carrier list leaves money behind.
Etsy & independent creators
When the next order could be a print or a framed piece, no single carrier stays cheapest. Re-running the comparison per parcel is easier than maintaining rules about which carrier gets what.
