Looking for a Simprosys alternative? AdNabu is a “Built for Shopify” app that pairs AI feed optimization with instant Shopify sync, headless store support, and plenty of other advanced features to help you boost your Shopify sales.
Simprosys has long been one of the most trusted and popular feed management software in the Shopify landscape. However, just like any other tool, it also has its shortcomings, such as:
Merchants describe a sudden spike in Merchant Center errors after setup, with fixes that proved difficult to undo once products were affected.
Long waits and repeated follow-ups to get an issue resolved, with some merchants left without timely help during urgent feed problems.
Some products have reportedly kept appearing in paid ads after selling out, so merchants paid for clicks on items shoppers could not buy.
Plans are tied to product count, so costs rise as your catalog grows, causing uncertainty about total costs.
These are not universal experiences, and many merchants are happy with Simprosys. But if any of them sound like a risk for your store, then considering an app like AdNabu (a.k.a Nabu for Google Shopping feed) can be worthwhile.
AdNabu is a Shopify product feed management app that helps merchants optimize their products with smart AI for Google Shopping and other leading channels, including Meta, TikTok, Bing, and Pinterest, all in line with each platform's data requirements.
Once products are optimized, the app syncs them and their attributes to Google Merchant Center and other channels accurately and instantly, through direct submission or a data feed URL.
AI feed optimization: AI generates product titles, descriptions, highlights, etc., and also assigns a score to each item so that you can understand how well your listing is optimized for performance.
Bulk editing of 70+ attributes: Edit product titles, identifiers, gender, color, size, and dozens of other key attributes across many products at once, rather than fixing them one by one.
Product review integration: Pull verified reviews from Judge.me, Loox, Okendo, Yotpo, and more into your Google Shopping listings to build trust and support approvals.
Import and export: Import and export product data in and out of the app in bulk with CSV files, so large catalogs and edits are quick to manage.
Keyword suggestions: Top keywords sourced from Google Keyword Planner help you optimize listings for the terms shoppers actually search.
Multilingual and multicurrency feeds: Create feeds in multiple languages and currencies to sell across countries from one store.
AdNabu has Shopify's prestigious “Built for Shopify” status, which means it meets Shopify's highest standards for speed, design, and merchant value. Simprosys does not currently carry this badge.
Our app lets merchants instantly sync any product data edit, whether minor or major, from Shopify to Google. This keeps your Google Shopping listings, Merchant Center feed, Shopify website, and real stock levels aligned, so shoppers always see accurate prices and availability, and you reduce the risk of disapprovals and account suspension.
AdNabu's support team is known for being fast, responsive, and genuinely helpful, and is available around the clock for any question or concern. Having worked with a wide range of stores and account types, the team brings practical, proven guidance to help your Google Shopping campaigns succeed.
AI credits power unsupervised feed enhancement that keeps optimizing your products in the background. This is especially useful for stores with thousands of SKUs and several target markets, which is often the case for Plus merchants.
The app integrates with Shopify Flow, product review apps, and currency and translation apps, and supports Shopify Product Taxonomy, metafields, metaobjects, and headless storefronts. This ensures you can leverage all of Shopify's capabilities seamlessly.
Start using AdNabu for free with no monthly fee, then move to a paid plan as you grow. You can set up your feed and see value before you commit to a subscription.
Here is a tabular comparison of how AdNabu differs from Simprosys:
The Google and YouTube app starts for free and is fine for a basic connection between your Shopify store and Merchant Center. AdNabu is built for merchants who want granular control over product data enrichment and item-level visibility on Google Shopping, making it the stronger choice for merchants who want their feed to actively drive performance and sales.
The headline difference is how each app handles scale. With Simprosys, a growing catalog moves you into higher tiers and adds AI and feed charges on top, so the real monthly cost can climb well beyond the base price.
With AdNabu, the paid plans remove product limits entirely and bundle in AI optimization and multi-country feeds, so your pricing stays predictable as you grow.
Support matters most when a feed issue puts your ads at risk, and you need a quick resolution. Here is how the two compare:
Both apps are well regarded for support. The difference is access: Simprosys reserves dedicated account management mainly for enterprise and agency partners, while AdNabu includes it with priority support on the Plus plan.

Migrating from Simprosys to AdNabu is straightforward if you follow the steps listed below carefully:
Open your current Merchant Center product list and note the exact ID pattern Simprosys uses, whether variant ID, product ID, SKU, or handle. Set that same format in AdNabu before anything is pushed, because if products go live under new IDs, their performance history is lost.
AdNabu opts all products in and pushes once a plan is active, so turn off auto push first. Point the app at your existing Merchant Center feed container rather than creating new ones, and for multi-country stores, reuse each market's container and match the ID format across every locale. Keep your product titles unchanged to be safe.
Connect AdNabu and check right away that products are syncing under identical IDs, reviewing each market separately if you sell across countries. Only once everything checks out, disconnect Simprosys. Never run both pushing at once, since that causes ID collisions and disapprovals, then watch Merchant Center for a few days to catch any issues early.
If you need a hand during the move, the AdNabu support team can help you match your IDs and check your feed so nothing is lost in the switch.
