Six jobs sellers still do by hand
They start when you add a second marketplace or region. Or when your stock moves to a warehouse or 3PL.
The last size sells twice
It sells on two marketplaces before the stock updates. You cancel one order, pay a fee, and your seller score drops.
On busy daysSales typed into the warehouse
Each marketplace sale is typed into the warehouse system by hand. One typo, and the stock count is wrong.
Every saleDelisting after every sale
After each sale, someone logs in to every other marketplace and ends the listing. Miss one, and it sells again.
Every saleThe supplier stock file
Your supplier sends stock as a file. Someone updates the sizes by hand, line by line.
Every new fileMissing product photos
New items go live without photos. Someone finds and adds them, one product at a time.
Every new productThe daily stock sheet
Each morning, someone exports a CSV and pastes it into Google Sheets for the warehouse or 3PL.
Every morning
We build software that does these jobs for you, made for your platforms and your rules.
Custom ecommerce integrations built for your shop
We build software for the jobs your team does by hand. It works with the platforms you already use, to your rules.
Stock
One stock count for every place you sell. A sale on one channel updates the others and your warehouse.
StockX, Alias, eBay, Shopify, your warehouse system
Orders
Marketplace orders go to your warehouse or 3PL, and tracking goes back. Orders with a problem are held for a check.
Amazon, Walmart, TikTok Shop, ShipStation, your 3PL
Listings
Your products are listed on each marketplace you choose. Each listing gets the photos, condition notes and price that marketplace needs.
eBay, Etsy, Whatnot, Amazon, Shopify
Supplier files
Your supplier's stock file is read when it arrives. Sizes and prices are updated without anyone typing.
CSV and Excel files, email, FTP, supplier APIs
Photos and product data
Products without photos get them from your files or the marketplace catalog. Model numbers are matched to the right product.
Shopify, eBay, StockX, your catalog
Reports and alerts
A stock sheet every morning and sales totals for your books. An alert when an order needs a person.
Google Sheets, Slack, email, QuickBooks
These are examples. We build only what your shop needs.

How a custom build compares
A simple link between one store and one marketplace is often free today. We build for what the apps skip: resale marketplaces, several regions, your warehouse and your own rules.

A small team of engineers in Dhaka, Bangladesh
You talk to the people who build it.
You create the API keys
You make the keys in your own accounts, limited to what the build needs.
You can revoke them any time
Switch a key off whenever you want. We never ask for your passwords.
It runs in your cloud account
We set it up in your own cloud account. The build and its data stay with you.
The source code is yours
You get all of the source code. Any developer can work on it later.
Questions before you start
What is a connection?
One platform or account we build for: your web store, a marketplace account, your warehouse system. Each one is $500, one-time. Take 3 or more and one of them is free.
What does the free trial run?
Your first link, free for 7 days: two of your platforms connected. For example your store and one marketplace, or a marketplace and your warehouse. No card. Keep it and those connections are billed as normal: $500 each, 3 for the price of 2. Don't keep it and we switch it off. You pay nothing.
What if it doesn't work?
Then you don't pay. You pay once, after it runs. If it doesn't do what we agreed, we switch it off and you owe nothing.
Why one payment and not a monthly fee?
You pay for the build. After that, the code is yours and runs in your own cloud account. There is nothing for us to bill each month, and no fee per order.
How long does setup take?
Live in about a day once we have access to your accounts. Some marketplaces must approve API access first, and that can take longer.
What happens after handover?
90 days of fixes are included, also when a platform changes its API. After that, each fix has a fixed price that we agree before we start. Or any developer can work on it, because you have the code.
What if a platform changes its API?
In the first 90 days after handover, we fix it at no cost. After that, it is a fixed price per fix, agreed before we start.
Where does it run, and what does hosting cost?
In your own cloud account. We set it up. The host bills you directly, usually $5–20 a month. We charge nothing monthly.
How do you get access to our accounts?
You create API keys in your own accounts, limited to what the build needs. You can revoke them at any time. We don't ask for passwords.
Am I too small for this?
Maybe. With under about 100 orders a month on two channels, a free app may be enough. A custom build makes sense with more channels, a warehouse or 3PL, or rules the apps don't cover.
Do we have to change the systems we use?
No. We build for what you already use, through its API. If a system has no API, we work from its exports.
What if one of our platforms is down?
The build tries again and continues where it stopped. Nothing is applied twice. Every action is logged, and you get an alert if a run keeps failing.
