How to Create a Product Catalog on GeM Portal

Getting your GeM registration approved is only the starting point. Your seller account does not earn you a single rupee until your products actually appear in front of government buyers — and that happens through your product catalog.

This is where most new sellers slow down. They log in, look at the dashboard, and realise that listing a product on the Government e-Marketplace is not like listing on a normal e-commerce site. You cannot simply upload a photo, write a two-line description and set a price. GeM asks you to place the product in a specific category, fill category-defined attributes, match specifications to the actual product, and support your claims with documents where the category demands it.

Get any of these wrong and the listing gets rejected, sits unapproved, or — worse — goes live under a category where no buyer is looking for it.

This guide walks you through the full process of creating a GeM product catalog: what to prepare before you start, how the step-by-step upload works, what usually goes wrong, and how to fix a rejected listing.

What Is a Product Catalog on GeM?

Your GeM product catalog is the complete set of products your seller account offers on the portal. Each product inside it is a structured listing — not free-form text, but a set of fields the portal expects you to fill correctly.

A single listing typically carries the product's category and sub-category, brand and model, technical specifications, images, price, available quantity, and any supporting documents the category requires.

Here is the important difference. Adding a product is a one-time data-entry action. Building a catalog means creating a set of listings that are correctly categorised, technically accurate, and consistent with each other — so that a buyer comparing five sellers can actually see what you are offering.

Government buyers rely heavily on this data. On GeM, a buyer often filters products by category attributes and compares technical parameters side by side before raising a demand or a bid. They are not visiting your website or calling your sales team first. Whatever is written in your listing is your sales pitch. If a required specification field is left blank or filled with a vague value, your product simply drops out of that buyer's filtered view.

This is also why accuracy is a compliance matter, not just a marketing one. What you declare in the catalog is what you are committing to supply.

Why a Well-Created GeM Product Catalog Matters

A carefully built catalog does a few practical things for a seller:

• Better discoverability. Correct category placement and complete attributes mean your product shows up when buyers filter or search within that category.

• Easier comparison. Buyers can evaluate your product against alternatives without having to guess at missing details.

• Fewer listing errors and rejections. Getting the details right the first time avoids repeated correction cycles.

• Stronger buyer confidence. Clear specifications, genuine images and complete documentation signal a serious supplier.

• Cleaner compliance. When your listing matches your actual product, brand authorisation and documentation, you reduce the risk of disputes at the supply or inspection stage.

None of this guarantees orders. What it does is make sure you are actually in the running when a buyer is looking.

What to Prepare Before You Start

Collect this information before you open the listing form. Half of all catalog problems come from sellers who start uploading and then hunt for missing details mid-way.

• Product name, as you want it to appear to buyers

• Brand name (and brand authorisation, if you are not the manufacturer)

• Model number / model name

• Complete technical specifications

• Correct category and sub-category

• HSN code, where applicable

• SKU or internal product identification details

• Product images that meet the portal's image guidelines

• Price and applicable tax details

• Available quantity or stock

• Warranty details, where applicable

• Certifications, test reports, or other supporting documents, where required

One caution: requirements are not uniform across GeM. A category may ask for certifications, mandatory attribute values, or authorisation documents that another category does not. Treat the list above as a preparation checklist, and confirm the exact requirements against the category you are listing under and the latest instructions on the portal.

If you are an authorised reseller rather than the brand owner, sort out your OEM authorisation before you begin. Listing someone else's brand without proper authorisation is one of the fastest routes to a takedown.

How to Create a Product Catalog on GeM Portal — Step by Step

Step 1: Log in to your GeM seller account

Sign in with your seller credentials and complete the applicable authentication. Once you are on the seller dashboard, check that your profile and business details are complete and current. Incomplete seller profiles can block or delay catalog activity.

If you have not completed this stage yet, start with GeM registration first.

Step 2: Open the product/catalog section

From the seller dashboard, navigate to the section where products and catalogs are managed, and choose the option to add a new product. The portal interface is updated from time to time, so the exact menu labels can differ from what you may have seen in an older tutorial. Look for the product/catalog area rather than a specific button name.

Step 3: Select the correct product category

This is the single most important decision in the entire process.

GeM organises products into a very large number of categories, each with its own defined set of attributes. Your category choice determines which specification fields you must fill, which documents may be requested, and which buyer searches your product will appear in.

Search for your product using the terms a buyer would use, then read the category description and its attribute list carefully before confirming. If two categories look similar, compare their attributes — the one whose fields actually describe your product is the right one.

Choosing a loosely related category because it seemed easier to fill is a mistake that costs sellers months. The listing may go live, but it sits somewhere no buyer is looking, and you have no visibility into why nothing is happening.

Step 4: Enter product details

Fill in the title, brand, model, specifications, features and description.

Two rules here. First, every value must match the actual product you will supply — the same model, the same rating, the same dimensions, the same make. Second, fill the attributes completely. Blank or "NA" values in fields that buyers use as filters will quietly remove you from comparison.

Write the title the way a buyer would describe the item, not the way your internal system names it. Keep the description factual and technical rather than promotional.

Step 5: Add product images

Images should clearly show the actual product being offered — not a stock photo of a similar item, and not a photo with another company's branding or watermark visible.

GeM applies image guidelines covering aspects like background, clarity and dimensions, and these can vary by category. Check the applicable requirements before uploading, and use the highest-quality images you have. A blurred or cropped image is often the difference between a buyer shortlisting you and scrolling past.

Step 6: Add price and commercial details

Enter the price along with applicable tax details, available quantity, warranty terms, and any other commercial information the category requires.

Price with your actual cost of supply in mind, including delivery obligations and applicable terms. Pricing rules and the way price is treated can differ between categories and procurement modes, so avoid applying a blanket formula you read somewhere.

Also keep quantity realistic. Declaring stock you cannot actually supply creates a fulfilment problem later, not a sales advantage.

Step 7: Upload supporting documents

Some categories and products require additional documentation — brand authorisation, test certificates, quality certifications, or compliance declarations. Upload documents that are current, legible, and clearly connected to the product being listed.

Mismatched documents (a certificate for a different model, or an expired authorisation) are a common cause of rejection.

Step 8: Review before you submit

Run a quick check on every listing:

• Correct category and sub-category

• Correct brand and model

• Specifications matching the actual product

• All mandatory attributes filled

• Clear, compliant images

• Correct price and tax details

• Correct quantity

• Valid, matching documents

• No spelling or data-entry errors

Five minutes of review here saves a full rejection-and-resubmission cycle.

Step 9: Submit the product

Submit the listing. Products may go through the applicable GeM review or approval process before they become available for procurement. Timelines vary depending on the category and the nature of the product, so track the status from your dashboard rather than assuming it is live.

Common Mistakes When Creating a GeM Product Catalog

1. Wrong category selection — the product goes live but never reaches the right buyers.

2. Copying specifications from a competitor's listing — you end up committing to a product you do not actually supply.

3. Poor-quality or non-compliant images — buyers cannot assess the product and the listing may be rejected.

4. Incorrect model numbers — creates a mismatch between the listing, the documents and the eventual supply.

5. Leaving mandatory attributes blank — silently removes you from filtered buyer searches.

6. Uploading mismatched or expired documents — a frequent rejection trigger.

7. Careless pricing entries — a decimal or tax error can commit you to a loss-making supply.

8. Vague or exaggerated descriptions — invites disputes at inspection.

9. Ignoring category-specific requirements — assuming one category's rules apply everywhere.

10. Submitting without review — the cheapest mistake to avoid and the most common one made.

How to Optimise a GeM Product Listing

Optimisation on GeM means making your listing genuinely easier to find, understand and trust — nothing more.

• Write clear product titles that use the terminology buyers actually use for that item.

• Complete every specification field with real values.

• Keep descriptions factual, specific and readable.

• Use sharp, compliant images that show the product honestly.

• Confirm category placement is exact, not approximate.

• Price accurately and competitively based on your real costs.

• Keep stock, price and product information updated.

What does not work: stuffing keywords into titles, adding unrelated terms to appear in more searches, or overstating capabilities. These do not improve your position in any reliable way, and misleading listings create compliance risk when an order actually comes in.

What If Your GeM Product Catalog Is Rejected?

Rejection is normal, especially for first-time sellers. It is a correction request, not a permanent block.

Read the rejection reason first. The portal usually indicates what went wrong — a category mismatch, an incomplete attribute, an image issue, or a document problem. Sellers waste days re-uploading the same listing without reading why it failed.

Then work through it in order:

• Fix the specific issue flagged, not everything at once

• Re-verify category and sub-category if the reason points to mapping

• Correct specifications so they match the product and its documents

• Replace images that do not meet guidelines

• Upload current, correct, legible documents

• Resubmit through the applicable process

Finally, apply the same fix across your other listings. If one product was rejected for a missing attribute, the rest of the catalog probably has the same gap.

GeM Product Catalog vs GeM Catalog Management

Creating a catalog is a project with an end date. Managing one is ongoing work.

Once your products are live, the catalog needs continuous attention: price revisions, specification changes when a model updates, image and document refreshes when certificates expire, category reviews when GeM restructures a category, inventory updates, and compliance monitoring.

A catalog that was accurate last year but has not been touched since is a liability. Outdated prices, expired documents and discontinued models create both lost opportunities and compliance exposure. This ongoing layer — updates, optimisation, monitoring — is what GeM catalog management actually covers.

When Should You Consider a GeM Catalog Management Consultant?

Plenty of sellers manage their own catalogs successfully, particularly with a small, single-category product range. Professional support tends to make sense when:

• You have a large product range to upload

• Your products span multiple categories with different attribute sets

• Your catalog needs frequent price or specification updates

• You have had repeated rejections and cannot identify the pattern

• Category attributes are technical and hard to map to your product

• Your team does not have the bandwidth for ongoing catalog work

• You need bulk uploads completed within a defined timeline

If none of these apply, the steps above are enough to get you started on your own.

8. Frequently Asked Questions

1. How do I create a GeM product catalog? Log in to your seller account, open the product section, select the correct category, enter specifications, upload compliant images and documents, add price and quantity, review everything, then submit for the applicable approval process.

2. What information is needed for GeM listing? Typically product name, brand, model, technical specifications, category and sub-category, images, price, quantity and HSN code. Certifications and authorisation documents may also be required depending on the product category you are listing under.

3. Can I upload multiple products on GeM? Yes. There is no fixed limit on the number of products in your catalog. Sellers with large ranges often use bulk upload approaches rather than creating each listing individually, which saves considerable time on multi-category catalogs.

4. Why is my GeM catalog rejected? Common causes include wrong category selection, incomplete or inaccurate specifications, images that do not meet guidelines, mismatched or expired supporting documents, and missing mandatory attributes. The portal usually states the specific reason — read it before resubmitting.

5. How do I choose a GeM category? Search using the terms a buyer would use, then compare the attribute lists of similar categories. The correct category is the one whose defined attributes actually describe your product. Never choose a loosely related category for convenience.

6. What images are required for GeM products? Clear images of the actual product you are supplying, meeting the portal's applicable guidelines on background, clarity and dimensions. Requirements can differ by category, so check the specific rules for your category before uploading.

7. Can product details be changed after listing? Yes, listings can generally be updated — prices, quantity, specifications and documents. Certain changes may require re-approval depending on the category and the nature of the edit, so verify the applicable process on the portal.

8. How long does GeM catalog approval take? Timelines vary by category and product type, and GeM does not apply a single fixed period across all listings. Track the status from your seller dashboard rather than assuming a standard turnaround.

9. Can a consultant manage my GeM catalog? Yes. A GeM consultant can handle catalog creation, category mapping, bulk uploads, specification writing, document management and ongoing updates — useful when you have a large range, multiple categories, or limited internal bandwidth.

10. How much does GeM catalog management cost? Cost depends on catalog size, number of categories, and whether you need a one-time upload or ongoing management. BizHelp's catalog management starts at ₹8,000/month, with bulk-volume pricing for larger catalogs.

Conclusion

Most sellers who struggle with their catalog aren't struggling because the process is complicated. They rush the two or three steps that actually matter — picking the right category, and checking the listing properly before hitting submit.

So take it slow the first time. Upload three or four products, see how the approval goes, and scale up once you know what your category expects.

If something gets rejected, don't just fix it and resubmit. Read the reason, then go check whether the same mistake is sitting in your other listings too. Usually it is.

And your catalog isn't a one-time job. Prices change, certificates expire, models go out of production. A catalog nobody has touched in a year quietly costs you more than it earns.
