Ship the orders.
Fix the listings.
Every other shipping tool stops at the label. Arub pulls orders out of Etsy, Amazon, eBay, Walmart and Shopify into one queue, puts USPS, UPS and FedEx in a price race for every package and sends the tracking number back — then gives each marketplace its own simple portal to fix the listings that produced the orders in the first place, on the same login.
Shipping Hub and every marketplace portal have a free plan that never expires. You buy your own postage at the carrier's price with nothing added, and Arub AI is charged only if you choose to use it.
What you get, in short
The long version is the rest of this page. This is the whole product in eight lines.
One queue
Every shop's orders in a single list.
Three carriers, one race
USPS, UPS and FedEx priced together.
Labels and slips
Buy, print, and pack in picking order.
Tracking sent back
The shop marks shipped without you.
A portal per marketplace
Edit, bulk change and grow each shop.
Unlimited users
Whole team, every plan, no seat fee.
Free plans
They never expire. No card, no label cap.
API and AI agents
REST, webhooks, and an MCP server.
Designed around the parts that go wrong.
Selling in five places at once breaks in predictable ways: the order that arrives twice, the label bought against the wrong box, the marketplace that will not accept a carrier's name, the listing edited in one place and forgotten in another. Arub is shaped around those moments rather than around a tidy demo.
What the platform covers today, not a roadmap. Screens shown on this site use example data.
Shipping Hub moves the packages.
The portals fill the shelves.
They share an account, a sign-in, a permission system and a bill. Take Shipping Hub, the portals for the marketplaces you sell on, 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, profit per order and reports, on a Dashboard you set up yourself. Ships with a REST API and a Windows print agent.
Marketplace Portals
A simple portal for each of Etsy, Amazon, eBay, Walmart and Shopify, dressed like that marketplace: a real editor, Bulk Changes, Arub AI, orders and sales — plus Competitors in the Etsy Portal.
Three carriers, one race, every package.
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.
- On an order, the same race runs by itself. Rates are fetched against the order and your pick is stored on it, so a batch run buys what you chose 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 package, 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.
Sixteen reports over your own data: orders due today, shipment status, tracking sent to shops, sales and revenue, sales channels, this year versus last year, estimated profit, carriers and shipping cost, carrier performance, fulfillment speed, products and SKUs, customer insights, where orders ship, balance history, postage refunds and USPS adjustments — every one filterable by date range.
- 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.
- Profit per order. Your own cost rules and the marketplace’s fees turn each sale into an estimated profit, split by product category.
Edit a listing properly, then push it once.
Marketplace listing forms are hostile. Arub gives Etsy, Amazon, eBay, Walmart and Shopify each their own simple portal with 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. See every portal.
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.
Bulk Changes
Check the listings you want, pick the change from one window — price, stock, photos, tags, text find-and-replace — and it runs in the background while you keep working.
Etsy Competitors
Inside the Etsy Portal: follow the shops you compete with, their sales and price changes, the tags and keywords that are moving, and where your shop ranks.
Copy to other marketplaces
Copy a listing into another shop, or into another marketplace you sell on, and Arub carries over what fits and clears what does not.
What sells, by listing, by marketplace, by date range.
Reporting covers Etsy, Amazon and eBay — the marketplaces that report views and sales per listing. Pick a report, a marketplace and a date range, and get units sold, revenue, top and worst performers, wasted traffic and price bands, updated from each marketplace's own numbers.
- Best sellers. By units and by revenue, filtered to one marketplace or all of them.
- What isn't selling. Active listings with no sales in the period, sorted worst first.
- Views but no sales. Traffic that never converted, and which listings waste the most of it.
- Trends and price bands. Units and revenue over time, which price ranges sell, and your top categories.
What connects today, and what does not.

Coming from another platform? Bring your history with you.
Arub imports your past orders, buyer addresses, line items, shipments and tracking out of the order management or shipping software you are on now, so your queue, your customer history and your reports start full instead of empty. If your current platform has an API or can produce an export, we can build the import for it — tell us what you are on and getting the data across is our job, not yours. How switching works.
Shipping Hub connects every marketplace on every plan — there is nothing to unlock and nothing priced per channel. The marketplace portals share one plan that covers every portal, and there is a free one. Shops connect through Arub's own marketplace apps, so you authorize a shop rather than hunting for developer keys. The full list of connections says what each one carries; moving from another tool covers importing the history you already have.
A first afternoon, roughly.
Connect a shop
Sign in to Etsy, Amazon, eBay, Walmart 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
Every account comes with 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 center 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. There is also an MCP server, so an AI assistant can work the queue in words rather than requests — ask it what is stuck today, or have it quote an order and tell you the cheapest ground service.
# 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.
Shipping Hub and every marketplace portal are free for your first six months — no card, no trial timer. The only things you pay in that time are your own postage and, if you use it, Arub AI. You will need an invite code, which we hand out to keep onboarding manageable — ask and you will usually have one the same day.
