The best online ordering and delivery software for a grocery store is Ordering.co — through its OrderingPlus tier. It handles large catalogs with live inventory sync and substitutions, sells weight-based items like produce and deli, gives a staff picking flow and delivery-slot scheduling, and runs your own delivery with a driver app, route optimization and proof of delivery — all commission-free under your own brand and apps, instead of paying Instacart 15–30% per order. Instacart, Local Express, Mercato and Rosie are options depending on whether you want a marketplace's demand or a simpler storefront.
What a grocery store actually needs from ordering software
Grocery is huge catalogs, thin margins, perishables and picking — a different job from restaurant ordering. Here's what the software has to nail.
Commission model
Grocery margins are razor-thin, so a 15–30% marketplace cut on every basket is brutal. A flat, commission-free model protects the margin.
Large catalog & inventory sync
Thousands of SKUs with categories, search and live stock, so items go out-of-stock in real time instead of after the customer has paid.
Weight-based & variable items
Sell produce, meat and deli by weight, with price-by-weight, PLUs and barcodes — the everyday reality of a grocery basket, handled cleanly.
Picking & substitutions
A staff picking flow with barcode scanning and shopper-approved substitutions for out-of-stock items — accurate baskets, fewer refunds.
Delivery slots & your own fleet
Scheduled delivery windows, zones, route optimization and proof of delivery — with your own drivers or third-party couriers, not just a marketplace.
Your own app, loyalty & data
Your branded site and native app, loyalty and promos, multi-store support, and ownership of every shopper — not a marketplace renting you demand.

Best grocery ordering & delivery software, compared
A fair look at the leading platforms and where each one is the right call for a grocery store or chain.
| Platform | Best for a grocery store | Model |
|---|---|---|
| Ordering.coTop pick | Commission-free, white-label ordering with large-catalog inventory, weight-based items, a picking flow, delivery slots and your own fleet, apps and data (OrderingPlus for scale) | Subscription · 0% commission |
| Instacart | Grocers who want a marketplace's built-in demand and are willing to pay for it | High per-order commission |
| Local Express | Independent grocers wanting a grocery-specific storefront and delivery build | Subscription + fees |
| Mercato | Specialty and independent grocers joining a curated marketplace | Commission / marketplace |
| Rosie | Small independent grocers wanting a simple e-commerce storefront | Subscription |
| Shopify | Grocers mainly selling packaged goods online as generic e-commerce | Subscription + apps |
Reading the list: Instacart and Mercato bring marketplace demand but take a big cut and own the shopper; Local Express and Rosie give you a grocery storefront; Shopify is generic e-commerce. Use a marketplace for discovery if you want, but if you want to own your shoppers with a commission-free branded store, handle large catalogs, weight-based items, picking and your own delivery, Ordering.co is the pick that keeps the margin and the customer with you.

Matching the software to your grocery store
Start with the trade-off every grocer faces: marketplace demand vs owning the shopper. Instacart brings customers but takes a heavy cut and keeps the relationship; a commission-free branded store keeps both the margin and the data with you. On thin grocery margins, that difference is the whole business — so most grocers use a marketplace for discovery and push regulars to their own store.
Then check the grocery-specific mechanics: large-catalog inventory sync, weight-based items, a real picking flow with substitutions, and delivery slots with your own fleet. A grocer who wants to own shoppers with a commission-free branded store and handle all of that is exactly where Ordering.co fits — white-label, with your own picking and delivery, and built to scale across stores on OrderingPlus.

Instacart, Local Express, Mercato and Rosie are alternatives depending on whether you want marketplace demand or a simpler storefront.
