How to keep pre-order and in-stock items in separate Shopify orders
When customers mix pre-orders with in-stock items, someone eats the shipping cost. Here is how to block mixed carts so each order ships on its own schedule.
New Back-in-Stock Alerts are now part of Dash

One app, four jobs
Everything between cart and confirmation.
Use each tool on its own or together. They all live in one Shopify app, with one place to manage your rules.
01
Order Limits
Quantity, price, weight, and per-customer limits that hold up in cart and checkout, plus customer memory that works across orders.
- Per customer
- Max quantity
- Time-based
- Lifetime
- Mixed cart
- Weight
02
Bulk & wholesale orders
Mark hundreds of pickup orders ready in one click, and set wholesale minimums by customer tag.
03
Checkout Rules
Hide, rename, or reorder shipping options and payment methods based on cart, customer, or destination.
New
Back-in-Stock Alerts
Shoppers tap “Notify me” on sold-out products, and Dash emails them the moment you restock, so you can still make the sale.
01
Order Limits
Control what, how much, and how often.
Set quantity, price, weight, and customer-based limits, and show shoppers a clear, translatable message when they hit one.
Limits that remember your customers
Track lifetime purchases per customer. Cap by quantity or spend over a day, week, month, year, or lifetime.
Enforced where it counts
Rules are validated in real time in cart and again at Shopify Checkout, so shoppers can't get around them and you don't oversell.
Fair access on big drops
Use one-per-customer caps, VIP early access, and wholesale minimums to keep high-demand launches orderly.
Every kind of limit, one rule builder.
Pick the rule you need. Each one has a guide with setup steps and examples.
Customer purchase limits
Caps that count a customer's past orders along with the current cart.
Maximum quantity limits
Set a max per product, variant, or the whole cart.
Time-based limits
Daily, weekly, monthly, or yearly windows that reset on their own.
Lifetime purchase limits
Caps like “Max 5 per customer, ever,” backed by purchase history.
Mixed cart limits
Rules that apply across a group of products sharing one cart.
Weight order limits
Keep carts within the weight you can actually ship.
Wholesale minimums
Minimum order quantities by customer tag for B2B buyers.
Limit one per customer
The classic drop rule, enforced at Shopify Checkout.
02
Bulk order management
Hundreds of pickup orders, ready in one click.
Stop clicking through orders one by one. Select your pickup orders, run one bulk action, and every customer gets Shopify's standard pickup notification.
Bulk ready for pickup
Mark multiple orders ready at once, right inside your Shopify admin.
Built for busy pickup days
Made for stores handling POS and in-store pickup, where rush periods mean dozens of orders at a time.
Wholesale minimums by customer tag
Require minimum order quantities for wholesale buyers while retail customers keep normal rules.
03
Checkout Rules
A checkout that adapts to every cart.
Each shopper sees only the shipping and payment options that apply to their cart, which means fewer confused customers and fewer support tickets.
Shipping rules
Hide express shipping for oversized carts, put the free option first, or rename methods so they make sense to shoppers.
Payment rules
Hide Cash on Delivery above a certain order value, reorder payment methods by preference, or limit options by country.
Conditions you already think in
Cart subtotal, customer tags, logged-in status, products in cart, countries, and zip codes. Combine them however you need.
04
Back-in-Stock Alerts
Sold out shouldn't mean sale lost.
A sold-out product page usually means the shopper leaves. Back-in-stock alerts let them sign up instead, and Dash keeps the list and emails them when you restock.
Capture demand while you restock
A notify-me form appears on sold-out products automatically. Shoppers leave an email address and don't need an account.
Alerts send themselves
When inventory comes back, Dash emails everyone who asked. Set thresholds, batch sizes, and delays so drops don't oversell.

Under the hood
Built on Shopify's own checkout platform.
Dash uses the same building blocks Shopify gives its own checkout, so your rules don't break on the next theme update and behave the same way everywhere.
Shopify Functions
Order limits and checkout rules run on Shopify Functions, without checkout.liquid or theme hacks.
Checkout extensions
Works natively with Shopify Checkout, the same checkout your customers already use.
130+ languages
Limit messages translate automatically. Back-in-stock emails can be written per locale.
Customer memory
Lifetime purchase tracking, so caps like “5 per customer, ever” mean exactly that.

Tips, guides, and case studies for Shopify merchants
Best back in stock apps for multi-location Shopify stores (2026)
Most restock alert apps only see your total inventory, so a warehouse restock on another continent can email customers who cannot buy from it. We compared six apps on per-location triggers, notify thresholds, and oversold handling.
