Four shops, three carriers,
one queue
Every connection on this page is built, tested end to end and working today. If a marketplace or carrier is not here, it is not connected yet — we would rather say so than list a logo and let you find out later.
Where your orders come from
Each of these connects through Arub's own marketplace app. You sign in to the shop, approve Arub, and come back — there are no developer keys to hunt for and nothing to paste into a settings box.
Etsy
Orders arrive within minutes of being placed, with the buyer's address, the line items and any personalization note. Tracking goes back automatically when you buy a label, so the order marks as shipped on Etsy without you opening it.
- Full listing editor, including photos, tags, materials and shipping profiles
- As many Etsy shops as you run, on one login
- Cancellations on Etsy pull the order out of your queue
Amazon
Seller Central orders, including Prime and anything with a promised ship-by date. Arub keeps both dates on the order so you can see what is due today rather than working it out from a list of timestamps.
- Full listing editor with bullet points, A+ content and variation families
- Buyer-paid shipping and tax captured on the order, not rounded to zero
- Confirmed shipments pushed back with the carrier and tracking number
Walmart
Marketplace orders in, tracking out, and cancellations handled in both directions — including the awkward case where a buyer asks to cancel while you are already holding a label.
- Full listing editor with price, stock, key features and attributes
- Reusable profiles so a price rule is written once and applied to hundreds of items
- Carrier names translated to the ones Walmart will accept
Shopify
Your own storefront alongside the marketplaces, in the same queue and with the same rate comparison. Fulfillments are written back to Shopify so the customer gets the shop's own notification.
- Full listing editor with variants, options, stock and media
- Several stores on one account, each with its own settings
- Manual orders too, for anything sold off-platform
Temu
Orders in, tracking out and a full listing editor, built the same way as the marketplaces above. It is finished work waiting on release rather than an idea on a roadmap.
TikTok Shop
The same again for TikTok Shop, in the same queue as everything else you sell. No extra charge when it lands — every marketplace is included on every plan.
Every marketplace, on every plan
There is no channel pricing here. Whatever plan you are on, free included, you can connect every marketplace Arub supports and as many shops on each as you run. The ones marked coming soon will simply appear.
Already selling somewhere with another tool?
Your history does not have to stay behind. Arub imports past orders, addresses, line items, shipments and tracking from the platform you are leaving, and if that platform has an API or an export, we can build the import for it. How switching works.
Not on this list?
Then it does not connect yet, and no amount of reading this page will change that. Tell us which one you sell on when you sign up — what customers actually ask for is how the order of work gets decided, and a marketplace two people want beats one nobody has mentioned.
Who actually carries the parcel
Connect the accounts you already hold and you pay your own contracted rate with nothing added by us. Hold none, and there is a managed USPS option so you are not stuck.
| Carrier | Live rates | Labels | Void | Tracking |
|---|---|---|---|---|
| USPS, your own account | Yes | Yes | Yes | Webhooks |
| Arub USPS, managed | Yes | Yes | Yes, refund queued | Webhooks |
| UPS, your own account | Yes | Yes | Yes | Webhooks |
| FedEx, your own account | Yes | Yes | Yes | Webhooks |
Bring your own accounts
Your USPS, UPS or FedEx credentials go in once and the rates you see are the rates you negotiated. Arub takes no percentage and adds no per-label fee, on any plan.
Or use none at all
Arub USPS is there for sellers with no carrier account, priced below the counter and funded from a postage balance you top up. It carries a small margin, shown in the price before you buy.
International and customs
Non-US parcels build their customs declaration from the line items using defaults you set once, and the electronic form travels with the label.
| What | State |
|---|---|
| DHL | Coming soon |
| GoFo | Coming soon |
| Amazon Shipping | Coming soon |
| Seller Fulfilled Prime | Coming soon |
| MCF against your FBA inventory | Coming soon |
Rates, voids and tracking all run against the carrier directly. When a carrier refuses something, you get the carrier's own words for why, translated into plain English rather than reduced to an error code.
Getting the label onto paper
Any printer you already own
Thermal label printers and ordinary office printers both work. Paper size is a setting on the account, so a four-by-six roll and a sheet of letter paper are a choice rather than a surprise.
Windows print agent
A small Windows app that takes labels straight to a chosen printer, so a day's batch does not become a hundred browser print dialogs. Stations can be shared with the team.
One file, in picking order
A batch prints as a single file ordered the way you walk the shelves, with the packing slip behind each label instead of in a separate pile.
If it is not on this page, connect it yourself
Orders, rates, labels, batches, customers, products, inventory and reports are all reachable over a documented REST API, and an MCP server puts the same operations in front of an AI assistant. Carrier scan events arrive over webhooks rather than being polled.
On the free plan, the API buys USPS labels
Reading orders, quoting every carrier you have connected, tracking and reports are the same on every plan. Buying UPS or FedEx labels over the API is part of a paid plan. Inside the app, a free account buys from any carrier it has connected.
Connect one shop and see.
It takes a couple of minutes, nothing on the shop changes, and the free plan has no expiry.
