Three steps, then a list every morning.
Add it to your store
Nextstock reads your sales and stock from Shopify on its own. No files to upload.
Tell it how long orders take
Tell it how many days your orders take to come. One number for the whole store is fine. Your list shows up once you do.
Check your list
It updates every night. Open it when you are about to place an order. You make the call.
Coming from Stocky?
Stocky shut down on August 31, 2026. Shopify still has purchase orders. Nextstock tells you what to put on them: which products, how many, and by when. Then you make the order in Shopify.
Nextstock does not bring over your Stocky data. It reads your sales straight from Shopify. It is not made by Shopify or by the Stocky team.
Every row shows its math
Each row tells you where its number came from, in plain words. You can check it on paper.
- How many to order, and about what it costs if your costs are in Shopify
- The day to order by, so it comes before you run out
- When you will likely run out, and how soon if sales run high
- Each step of the math that got there
You sold 108 in the last 30 days, up 15% from the 30 days before. We plan on about 3.6 a day. Ember Goods takes 14 days to deliver. You order every 7 days and want 30 more days of stock. That is 51 days. 51 days at 3.6 a day is 184. We take off 3 because most weeks sell a little under the average. We add 17 more to be safe (Balanced). That makes 198. You have 52 on hand and 0 on order, so you need 146. Order 146 (about $584). You will likely run out around Oct 6, or as soon as Oct 3 if sales run high. Order today. It comes Oct 5, 2 days after you may run out.
| 51 days × 3.6 a day | 184 |
|---|---|
| Take off | −3 |
| Add to be safe | +17 |
| Stock to aim for | 198 |
| On hand | −52 |
| Order | 146 |

Straight answers
A forecast is a best guess
Nobody knows next month's sales for sure. So each row gives a likely run-out date and an early one. It also says which numbers we guessed.
We look back 2 years
When you add the app, we read up to 2 years of your sales. So the list can see last year's busy season. After that, each night we only read what changed.
We don't keep customer details
We read what sold, how many, and when. We never ask Shopify for your customers' names, emails, or addresses.
Real people answer
Write to support@nextstock.app and a person reads it.
About $1 a day to stop running out.
What did your last empty best seller cost you? Nextstock starts at $29 a month. Every row shows its math, so you can check it before you trust it.
Starter
One person, one store.
Up to 500 active products
or $290 a year
Standard
A busy store with lots to reorder.
Up to 2,000 active products
or $590 a year
Growth

Up to 5,000 active products

Bigger store
More than 5,000 active products? We will set up a plan for your store.
Every plan has every feature. We count products the way your Shopify Products page does. A shirt in 3 sizes is 1 product. We only count the ones that sold or had stock in the last 90 days. The app counts yours and tells you which plan fits. Pay for a year and get 2 months free.
14 days free. Remove it before day 14 and you pay nothing. You pay through your Shopify bill, and you can change plans any time.
Go over your plan? Nothing stops working and nothing is charged by itself. We only ask you to move up if you stay over for two months in a row.
Founding shops: the first 20.
The first 20 shops from the early-access list keep their price for as long as they keep Nextstock installed. If we raise prices, they do not pay more, even if they move to a bigger plan. They also get a setup call with the founder to put in their supplier lead times, and the founder's direct email. We ask for one short call after 30 days.
Before you ask
What does Nextstock read from my store?
Your orders, products, stock, and locations. From each order we keep what sold, how many, when, which sales channel it came through, and any returns.
What does it never read?
Who your customers are. We never ask Shopify for your customers' names, emails, addresses, or phone numbers. If Shopify sends any of that anyway, we throw it away. Our privacy policy has the full list.
Will the numbers always be right?
No. They are estimates. Sales can surprise anyone. That is why each row shows its math and an early run-out date. If a number looks wrong to you, go with your gut and tell us.
How does the free trial work?
Every plan starts with 14 days free. The 14 days start when you pick a plan. You pay nothing during the trial. If you remove the app before it ends, you owe nothing. If you remove the app and add it back, you may not get a new trial. Used Stocky? Say so in your early-access email and we will make your trial 30 days.
What is an active product?
It is a product, counted the way your Shopify Products page counts it. A shirt in 3 sizes is 1 product. We only count products that sold or had stock in the last 90 days, and only ones Shopify keeps a stock count for. The app shows you your number before you pick a plan.
How do I cancel?
Remove the app from your Shopify admin. Shopify stops the plan right away. If you paid for a year, the months you did not use are not paid back. We delete your store's data about two days later. Our nightly backups hold a copy for up to 27 days, then that is gone too.
When can I install it?
Soon. Shopify checks every app before it goes in the App Store, and Nextstock is getting ready for that. Email us and we will tell you the day it is ready.
