If you searched for how to build a product catalog, you have probably landed on the same advice everywhere: use InDesign, set up master pages, apply paragraph and character styles, then automate with Data Merge or a plugin like EasyCatalog. This advice is not wrong. For a lot of teams, it is still the right starting point. But it comes with a ceiling, and most catalog owners do not find that ceiling until they are already deep into a launch, staring at 2,000 SKUs and a spreadsheet that refuses to behave.
This guide breaks down what InDesign, Data Merge, and EasyCatalog are actually good at, where each one starts to strain, and when it makes sense to move to a platform built specifically for catalog automation, like Catalogy.
For catalogs with a stable design and infrequent updates, InDesign is still one of the most capable tools available. The core building blocks are:
Master or parent pages Set up your repeating layout once, then apply it across dozens or hundreds of pages in a few clicks. This is the single most important InDesign skill for catalog work, and it is why designers consistently recommend it over Illustrator or Word for anything with repeating product layouts.
Paragraph and character styles Define your type specs once (font, size, color, spacing) and apply them across the whole document. Need to change every price to a new color or size? Update the style, not each individual text box.
This setup works well when:
Where it starts to break down: every one of those four conditions tends to disappear as a business grows. Product counts climb, marketing wants faster turnaround than design bandwidth allows, and "just update the InDesign file" becomes a bottleneck instead of a shortcut.
Once a catalog outgrows manual updates, the next step is usually one of two paths.
Data Merge Built into InDesign, Data Merge pulls from a CSV and populates a rigid, repeating layout, most commonly used for tables and simple, uniform product grids. It works well for straightforward data. It struggles the moment you introduce varied layouts, multiple images per product, or any product family that does not fit neatly into one template shape. Teams using Data Merge for image-heavy catalogs often end up doing extra manual work just to get metadata and images to merge cleanly, which defeats some of the point of automating in the first place.
EasyCatalog A third-party plugin built for heavier automation and larger, more frequently updated catalogs. It connects to more complex data sources and handles bigger volumes than Data Merge alone. The tradeoffs are real:
For design agencies working on retainer, this is a common and reasonable calculation, license once, bill many. For an in-house marketing or sales team that just needs catalogs to go out the door, it is often more overhead than the job requires.
Across InDesign, Data Merge, and EasyCatalog, the same three friction points keep showing up:
None of this makes InDesign or its plugins bad tools. It makes them tools built for a design-led production process, not a marketing-led, high-frequency update process. That distinction is the whole story.
Catalogy was built around the exact friction points above, specifically for teams whose catalogs update often and whose day-to-day owner is marketing or sales, not a trained designer.
Master feed instead of master pages: Connect your product data once (CSV, Excel, Google Sheets, PIM, or ERP), and every page pulling from that feed updates automatically when the source data changes. No re-import, no re-merge, no manual re-entry. One sync and hundreds or thousands of SKUs update at once.
No per-template charges, no plugin license: Build as many templates as you need. There is no EasyCatalog-style annual subscription to absorb or mark up, and no vendor-imposed template cap, as with some legacy pagination tools.
Built for non-designers: Templates are built once, either by your team using a drag-and-drop editor or by Catalogy's internal design team based on your brand guidelines. After that, updating a catalog is a drag-and-drop action, not a design task. This is the single biggest shift for teams currently bottlenecked on "waiting for the designer to have time."
Image handling without the workaround: High-resolution zoom and detail views work natively inside the catalog. Buyers do not need a separate Drive link to inspect a product closely, and you do not need to choose between a bloated file and a degraded image. On top of that, products can be turned shoppable, with clickable links that take buyers straight to an order form, quote request, or product page, so the catalog does more than showcase, it converts.
Visibility InDesign was never built to give you: Once a PDF or printed catalog ships, you have no idea what happened to it. A live, data-connected catalog comes with analytics: views, clicks, time on page, and heatmaps showing exactly which products buyers engaged with. That is information InDesign has no way to surface, automation plugin or not.
Most of the scenarios above describe a catalog at a specific size, before growth, before update frequency picks up, before a designer becomes a bottleneck instead of a resource. InDesign, Data Merge, and EasyCatalog are fine until that shift happens. Catalogy is built for what comes after: a master feed that syncs automatically, no design skill required to publish, and analytics that show what buyers actually engaged with.
The one real exception is a distributor requiring a native InDesign file. No platform changes that, so keep InDesign for that specific deliverable. But that's a narrow exception, not a reason to run your whole catalog operation through a design-led workflow, and it's usually the last piece standing once teams make the switch.
Is InDesign still worth learning for catalog work in 2026?
Yes, particularly for anyone doing design work across multiple mediums, not just catalogs. But for a marketing or sales team whose only goal is fast, frequent catalog updates without designer involvement, InDesign expertise stops being the constraint that matters. The bottleneck moves from "can we design this" to "can we update this fast enough."
What is the real difference between Data Merge and EasyCatalog?
Data Merge is free, built into InDesign, and best for simple, rigid, table-style layouts from a CSV. EasyCatalog costs money (license plus annual subscription), takes longer to learn, and handles larger, more complex, more frequently updated catalogs with more data source flexibility. Neither one removes the need for InDesign skill to operate them.
Do we have to give up InDesign entirely to automate our catalog?
No. Many teams keep InDesign for specific deliverables, like a distributor requiring a native file, while moving their primary catalog production to a platform that does not require design skill for routine updates.
How much SKU volume justifies moving off manual InDesign updates?
There is no universal number, but a strong signal is time, not volume. If updating your catalog now takes longer than a day, happens more than twice a month, or routinely waits on a single designer's availability, the workflow has already outgrown a manual process, regardless of exact SKU count.
Can a platform like Catalogy still give buyers a downloadable PDF if they need one?
Yes. A live, web-based catalog can typically still export a print-ready or downloadable PDF version, so buyers who prefer that format are not left out while the primary experience runs as an interactive, automatically updating catalog.
