Choosing a webshop builder for large catalogs

Which webshop builder to use for a store with many different products

A brand manager for one of the biggest book shop chains in southern Europe is wrestling with a tough platform decision. Their physical catalog runs over 100,000 items, but their webshop – built on Magento Commerce – only displays about 10,000. That gap means missed revenue. With roughly €15 million in lifetime webshop sales, they know the right platform can unlock the other 90,000 products. But finding a builder that handles both massive SKU depth and a clean, modern storefront isn't straightforward.

The core problem isn't just number of products – it's how customers find them. A cluttered layout on Magento makes browsing hard for shoppers. The brand manager wants a refresh that scales. This mirrors a challenge many growing retailers face: you start with a few hundred items, then inventory explodes, and the platform that worked at 1,000 SKUs chokes at 10,000.

From an operator's perspective, the choice comes down to three variables: cost per SKU, search and filtering capabilities, and the ability to maintain load speed when you add hundreds of categories. BigCommerce, Shopify Plus, and open-source options like WooCommerce each trade off differently. The book chain's experience suggests that if you're sitting on a large offline catalog, moving online should be gradual – but only if the new platform supports bulk import, custom attributes, and tiered pricing out of the box.

Why this migration matters for large-catalog retailers

The book chain's situation isn't an outlier. Many retailers in categories like books, spare parts, or craft supplies hold inventory in physical stores or warehouses that never makes it online. They lose walk-in traffic that could become repeat web buyers. The push to bring those 100,000 items online is driven by a simple math: even a 5% conversion rate on the missing 90,000 products adds significant top-line revenue at minimal marginal cost.

This trend is especially relevant for Shopify store owners who are moving beyond a single niche. If you're currently selling 500 jewelry SKUs and planning to add 5,000 book titles or home goods, the platform decision you make today determines whether you'll spend six months migrating later. The source case study makes one thing clear: don't assume Magento scales gracefully – it requires heavy custom development for large catalogs, which eats margin.

For suppliers on our platform, this shift creates a clear sourcing angle: bookstores and large-catalog retailers upgrading their webshops often refresh their product lines too. They look for unique accessories, gift items, and reading aids that differentiate their store from Amazon. Products like creative book page holders, literary jewelry, and stress relief items for customers browsing long catalogs become easy upsells.

Who needs this decision framework

This article serves three distinct operator profiles. Each faces a slightly different version of the same problem – scaling a product catalog without breaking the user experience or the bank.

Bookstore owner with 50,000+ SKUs

You're sitting on a mix of in-print and backlist titles. Migrating from an old Magento setup? You'll need a platform that handles custom product attributes like ISBN, author, and publication date efficiently.

Multi-category retailer scaling from 1,000 to 10,000 SKUs

You currently sell via Shopify but plan to add categories like home, accessories, and gifts. The book chain's experience proves that platform speed and search filters must be tested before you launch the new catalog.

Wholesale buyer sourcing for bookstore chains

You want to supply items that complement large catalogs – book accessories, reading aids, and gift bundles. Knowing the retailer's platform constraints helps you pitch products that fit their new storefront's layout.

How to sell products to large-catalog retailers upgrading their webshop

When a chain like the one in our source revamps its online store, it doesn't just change platforms – it rethinks the entire customer experience. That opens doors for products that enhance browsing, reduce cart abandonment, or increase average order value. You want to position your items as solutions to specific problems their new storefront will face. Focus on three angles: first, sell book-themed accessories that act as impulse buys on product pages. Second, offer organizational tools that retailers themselves might use for inventory management (though you'll sell those B2B, not retail). Third, bundle gift sets that test the new platform's upsell capabilities at low risk. The products below with high margin and low SKU complexity work best for these approaches.

Etsy and own Shopify store (B2C)$5.61 per page holder, $1.35 per locket

Target book lovers who shop on bookstore sites. List the Resin Thumb Book Page Holder (ID 274083) as a 'perfect gift for the reader' at $6.99, sourcing cost $1.38. Also pair with the Vintage Stainless Steel Book Locket Necklace (ID 300622) in a 'bookish jewelry' collection.

⚠ Low differentiation – many book accessories are generic. Differentiate with original packaging or bundle discounts.

B2B wholesale to bookstore chainsWholesale: $0.70-$1.00 per sticker book, $0.15 per coloring book

Pitch the Reusable Jelly Sticker Book (ID 314534) and Adult Stress Relief Coloring Book (ID 291007) as add-ons for children's and relaxation sections. Offer bulk discounts on 100+ units. Margins hold better when selling wholesale.

⚠ Longer sales cycle – bookstore chains may take 3-6 months to onboard new suppliers.

Amazon FBA (B2C)$2.00-$3.00 per organizer, $0.20 per jar opener

List the Multi-Layer Makeup Organizer (ID 257982) and 4-in-1 Jar Opener (ID 277484) as 'desk accessories for home offices' – a generic angle that works across demographics. Use Amazon A+ content to show multiple use cases.

⚠ High competition on price. Need strong PPC budget to win Buy Box.

Top products for the large-catalog retailer refresh

These items made the cut because they align with two scenarios: (1) products that bookstores and catalog-heavy retailers can sell as add-ons, and (2) tools that improve the shopping experience for customers navigating many SKUs. All prices are sourcing costs per unit from our platform.

Smart bundles for book-themed stores and large-catalog sellers

Bundling works especially well for retailers with huge catalogs because it increases average order value without requiring customers to search more. These bundles mimic what a bookstore or multi-category store could offer during their rebranding or platform migration.

Book Lover's Gift Set

A customer visits the bookstore's webshop looking for a gift under $30. This bundle fits the browsing budget and adds margin.

Frequently asked questions about webshop builders for large catalogs

Should I migrate from Magento if my catalog is over 50,000 SKUs?▾

The source case shows a major book chain struggling with Magento's layout after building only 10,000 online products. If you're spending more on custom development than on licensing, migration likely pays off in 12-18 months. Test Shopify Plus or BigCommerce with a 1,000-item subset first.

What's the minimum monthly budget for a platform that handles 100,000 products?▾

Expect $2,000-$5,000/month for hosted enterprise solutions like Shopify Plus, plus migration costs. Open-source WooCommerce can be cheaper but requires skilled developers – the source's Magento experience suggests developer cost quickly exceeds platform fees.

How do I keep site speed fast with thousands of products?▾

Use a headless architecture or a platform that offers content delivery networks built-in. The book chain's webshop likely suffered from slow load times with 10,000 products – adding 90,000 would make it worse. Optimize images (WebP format), use lazy loading, and limit the number of attribute combinations.

Can I sell on both Shopify and a separate Magento store?▾

Yes, but complexity grows exponentially. The source has a unified catalog across physical stores and webshop. If you run separate systems, inventory management becomes a nightmare. Stick to one primary platform and use a channel manager (like Linnworks) for marketplaces.

What product categories work best for bookstore webshops?▾

Book accessories like page holders ($1.38 sourcing), book lockets ($2.36), and adult coloring books ($0.34) have high impulse purchase rates. The source's chain could easily add these as upsells on book product pages, leveraging their existing customer base.

How do I handle international domains when selling many products globally?▾

The source's chain operates in southern Europe – they might consider ccTLDs for each country. Shopify Plus supports up to 9 stores under one subscription, which is cheaper than managing separate Magento instances. For 100,000 products, use a single store with multi-currency and geo-redirect instead.

What's the biggest risk when moving from Magento to another platform?▾

Data migration errors – especially product attributes, tags, and tiered pricing. The source mentioned a webshop that 'is not up to date' with only 10% of catalog online. If you migrate incomplete data, you'll lose SEO rankings and confuse customers. Run a full test on a staging environment before go-live.

Is it worth offering bundles for a large-catalog store?▾

Yes – bundles increase AOV by 20-40% in our experience. The book-themed bundles listed above (sourcing costs $1.38 + $2.36 + $0.34 = $4.08) can retail at $24.99, giving the retailer a 84% margin. Just ensure the bundling app you choose doesn't slow down product pages.

How many products should I launch initially after migration?▾

The source chain aims to go from 10,000 to 100,000 – but that's aggressive. A safer approach is to launch your top 30% of bestsellers first, then gradually add the rest over 6 months. This gives the new platform time to index and avoids overwhelming customers with choice paralysis.

What payment gateways work best for large catalogs in Europe?▾

Stripe and Adyen are solid for multi-currency. The source chain's €15M in sales likely had custom integrations with Magento. When moving platform, lock in a gateway that supports your local currencies and doesn't charge per-SKU fees – those add up fast with 100k items.

Should I use a platform that supports custom filters for book categories?▾

Absolutely. For books, filters like author, publication year, genre, and format are essential. Not all platforms handle custom attributes well – test this during trial. The source's dislike for Magento layout may stem from poor faceted search. Shopify Plus's native filtering is decent but may need a third-party app for complex ranges.

What to look for in a supplier when sourcing book accessories?▾

Check their catalog depth – you want at least 20-30 SKUs that match your store's aesthetic. Our platform offers items like the Resin Thumb Book Page Holder (ID 274083) at $1.38, with consistent quality. Ensure the supplier can handle bulk orders and has a returns policy for damaged goods, especially if you're importing.
