Sell on six marketplaces.
Ship from one screen.
Arub pulls orders out of Etsy, Amazon, Walmart, Temu, TikTok Shop and Shopify into a single queue, puts USPS, UPS and FedEx in a price race for every parcel, and pushes the tracking number back to the shop it came from. The listing side lives here too.
We wrote it for our own warehouse first.
Arub was not designed in a workshop. It was written to keep a real multi-marketplace operation moving, and it has been running that operation every day since 2020. Every awkward thing on this list exists because it broke for us on a Tuesday.
Figures are the live production instance as of 31 July 2026, not a projection. Carrier split to date: FedEx 199,588 · UPS 115,422 · USPS 66,779.
Shipping Hub moves the parcels.
Listing Manager fills the shelves.
They share an account, a permission system and a bill. Take one or both. Most people start with shipping because that is where the daily pain is.
Shipping Hub
Order import, live rate shopping, label buying, batch printing, packing slips, inventory, customers and reports. Ships with a REST API and a Windows print agent.
Listing Manager
A proper editor for Etsy, Amazon, Walmart, Temu, TikTok Shop and Shopify listings: photos, video, variations, personalization, attributes and tags, with Arub AI writing copy against marketplace rules rather than generic prose.
Three carriers, one race, every parcel.
Put in a size and a weight and Arub asks USPS, UPS and FedEx at the same time, then lays the answers out cheapest first with the delivery date beside each one. Services that normally hide from a rate shop, like UPS Ground Saver and FedEx Ground Economy, get their own request so they actually show up.
- Your accounts or ours. Plug in your own negotiated USPS, UPS and FedEx contracts, or ship on Arub's rates with no volume commitment.
- Pick a service and it sticks. The choice is stored on the order, so a batch run buys what you picked instead of quietly defaulting to cheapest.
- Multi-package and customs. One shipment across several boxes, and electronic customs papers built from the order for anything crossing a border.
Everything about one order, without a second tab.
Address, notes, gift wrap, personalization, the buyer's custom artwork, discount lines, package presets and the label itself sit on a single screen. Arrow keys walk you through the queue in the order you filtered it, so a packing session is a rhythm rather than a series of page loads.
- Merge and split. Combine two orders from the same buyer into one parcel, or split one order across several, with tracking still going back to the right place.
- Rules and presets. Auto-tag by channel, content or destination. Save your real boxes as presets and stop typing dimensions.
- Hold until a date. Park an order and it returns to the queue by itself when it is time to ship.
Find out what shipping actually costs you.
Nine reports over your own data: postage spend over time, spend and volume by carrier, which services you lean on, fulfilment speed, where orders go, what sells, orders due today, parcels bought but not moving, and whether tracking made it back to each shop.
- Bought but not moving. Labels paid for where the carrier has not scanned anything yet, which is where money quietly leaks.
- Tracking sent to shops. Every push-back attempt, why it failed, and a button to retry it.
Edit a listing properly, then push it once.
Marketplace listing forms are hostile. Arub gives Etsy, Amazon, Walmart, Temu, TikTok Shop and Shopify a real editor, holds your changes as a reviewable set, and sends them when you say so rather than the moment you touch a field.
Arub AI knows the rules
Titles, descriptions, tags, bullets and alt text written against each marketplace's character limits and policies. It will not put a brand name in a title it has no right to use.
Photos and video
Reorder by dragging, replace, duplicate, enhance, drop a white background in, stage a scene or generate a short lifestyle video. Fifteen minutes of undo on every photo edit.
Profiles instead of retyping
Save a set of variations, personalization questions or category attributes once and apply it to hundreds of listings. Change the profile and Arub offers to update everything linked to it.
What connects today, and what does not.
Beta software with a straight answer about its own edges. If something matters to you and it is not here, say so and it may move up the list.
| Connection | Orders in | Tracking back | Listings |
|---|---|---|---|
| Etsy | Yes | Yes | Full editor |
| Amazon | Yes | Yes | Full editor |
| Walmart | Yes | Yes | Full editor |
| Temu | Yes | Yes | Full editor |
| TikTok Shop | Yes | Yes | Full editor |
| Shopify | Yes | Yes | Full editor |
| USPS, UPS, FedEx | n/a | Live rates and labels | n/a |
Etsy, Amazon, Walmart, Temu, TikTok Shop and Shopify connect through Arub's own marketplace apps, so you authorise a shop rather than hunting for developer keys.
A first afternoon, roughly.
Connect a shop
Sign in to Etsy, Amazon, Walmart, Temu, TikTok Shop or Shopify from inside Arub and approve the connection. Orders start importing within a few minutes and keep arriving on a schedule.
Add a carrier, or don't
Enter your own USPS, UPS or FedEx account numbers to keep your negotiated pricing. Skip it and you can ship on Arub's rates immediately instead.
Buy one label
Open an order, take a rate, print. Once that feels right, group a day's orders into a batch and print the whole thing as one PDF in the correct paper size.
You are not left to work it out alone
The beta includes direct access to the people who wrote the software. If an import looks wrong or a carrier refuses a label, you get a real answer rather than a help centre article.
There is an API, and it is not an afterthought.
Ninety-four operations across sixty-seven paths. Anything you can do by hand in the Shipping Hub, your own software can do over HTTPS, including buying a label.
# every path starts at https://api.arub.com/v1 curl "$BASE/orders/50231/rates" \ -H "Authorization: Bearer $KEY" \ -d '{"length":14,"width":11,"height":5,"weight_lb":4}' curl "$BASE/orders/50231/label" \ -H "Authorization: Bearer $KEY" \ -d '{"rate_id":"usps_ground_advantage"}'
Try it on a real day's orders.
The beta is free, there is no trial timer, and you can keep your existing carrier accounts. You will need an invite code, which we hand out to keep onboarding manageable.
