Spend Monday in a spreadsheet. Or press Send.
ReplenishRadar counts your stock in every place you keep it, works out the day each product runs out, and writes the order in time. You check it and send it.
Doing it yourself takes about 47 minutes every Monday. With ReplenishRadar, a notification says the socks run out in 10 days and the Highland order is written; the order shows 60 in stock across the warehouse, Shopify and Amazon, selling 6 a day so 10 days left, Highland taking 7 days so order today rather than next Monday, 240 socks landing 3 days to spare; one tap sends it and Highland confirms. 14 free days to try it.
Set up a login and connect Shopify or Amazon. About five minutes. We read your products, orders, and stock. First forecast in hours, not minutes.
Sound familiar?
Sellers' own words, from the Shopify App Store, Amazon's seller forums, and Reddit. Under each: the part of this page that answers it.
“My best seller went to zero over the weekend. By the time I noticed, I lost three days of sales and my search ranking dropped.”
The report above names what runs out next, and how many days you have.
“Your vendor says 2 weeks but it takes 4.”
We record the real delivery time from every order, and plan the next one with it.
“My supplier takes orders on Tuesdays. Did I miss the cutoff?”
Each supplier gets its own order day. The reminder comes before it, with the order already written.
“I shipped 500 units to FBA three weeks ago. Amazon says 'Receiving.'”
We watch every shipment until Amazon's warehouse counts it in. If the count is short, we tell you.
Connect once. Get an order you can send.
Three steps from a connected store to an order your supplier can act on. The math happens in the middle, and you can see it.
Connect your stores
We use each store's own link. It takes about five minutes. We read your products, orders, and stock. Nothing in your store changes unless you click.
We do the math
Every product gets its own forecast. Supplier delivery time, smallest order, pack size, and your budget all go in. Enter them once, or we learn them from your past orders. The full working is a few sections down.
You approve and send
One click emails the purchase order to your supplier. It carries a link where they confirm quantities and ship dates. No link needed: email or a PDF works too. When you mark the goods received, your stock count updates.
Sending stock to Amazon, from start to end
You log in, say yes, and hand boxes to a carrier. Everything else is done for you.
Click any step, or just watch
Transfer day: Thursday
Log in on your transfer day. The work is already done when you get there.
Ordering from your suppliers, from start to end
You log in on your order day and say yes. The order is written, sent, watched, and checked in for you.
Click any step, or just watch
3 products. Arrives before you run out.
Next order day
Monday, the 8thEvery supplier has its own rhythm. The order is ready before the day comes.
Built around how sellers actually order
These are the parts that turn a low-stock list into the right order on the right day.
The right quantity, with your supplier's rules built in
Smallest order, pack size, budget, and ship time are worked out as one. You never round by hand, and you never break a supplier's rule by accident.
Reminders on the days you actually order
Each supplier has its own rhythm: weekly down the road, monthly overseas. The reminder comes before the next day you can order, not the day you run out.
Both stores on one screen, kept up to date
Your warehouse, Amazon's, any third-party one, and stock on the way, in one list. Shopify and Amazon send us every change as it happens.
Old stock at Amazon, before the extra charges land
Amazon charges more for stock that sits. We show how long each product has sat there, against our warning bands, so you can run a sale, cut the price, or pull it out in time.
A forecast for every product. And you can see the math
Steady, seasonal, or slow: each product is forecast the way it really sells, from as much as five years of your Shopify history. Returns are taken out. The holiday rush is planned for. Every number opens up to show how we got there.
Ask it in plain English
Which products are at risk, why this one is flagged, what to add to Monday's order. Every answer comes from your own numbers.
What we touch in your stores, exactly
We use each store's own link. You get a plain list of what we read and what we write. And you see results on your own numbers before you pay anything.
What we read
To connect Amazon you must be the main account holder. Or you must be an admin in Seller Central.
What we write, only when you click
Never your products. Never your prices or listings. And never the orders your buyers place.
Disconnect any time and our access ends right then. Delete your account from your dashboard whenever you like.
See it on your own numbers first

Built for Shopify and Amazon sellers. Support answers within 24 hours on work days. The people who reply know stock.
What we don't do
We do not do your books. We are not warehouse software. We do not print shipping labels.
We support Shopify and Amazon. Not ten platforms done poorly. Two done well.
We don't bounce you through a ticket maze. You get answers from people who know stock.
We do one thing: make sure you never run out of what sells, and never sit on what doesn't.
