Q4 is one of the best times to make money selling on Amazon, but waiting for inventory to reach Amazon's warehouses can cost you valuable sales. Between shipping delays and check-in lag, your products can sit for weeks before you can sell them.

Fulfilled by Merchant (FBM) offers another option. Instead of sending inventory to Amazon, you can sell products you have on hand and ship orders directly to customers. And with the right sourcing strategy, you can find profitable products you're already approved to sell without submitting ungating documents.

Why FBM Is a Big Opportunity During Q4

As holiday demand increases, popular products sell out, and FBA sellers can't always restock quickly enough. That creates opportunities for you to win more Buy Box share with FBM.

By mid-to-late November, FBM can become especially attractive as demand rises and FBA inventory runs low.

The biggest advantage is speed. Instead of waiting weeks for an FBA shipment to check in, you can sell ready-to-ship inventory and start fulfilling orders right away. That means getting your money back sooner and putting it toward sourcing more products.

How to Find Profitable Ungated Products

Even as a new seller, some brands are auto-ungated, meaning you can start sourcing and selling those products right away without applying for approval.

One of the easiest ways to find these opportunities is through storefront stalking: check what other sellers are offering to uncover profitable products you can sell, too.

Here's how to do it:

1. Find a product selling well on Amazon.
2. Check the seller's other products for potential sourcing opportunities.
3. Run those ASINs through Boxem's Bulk Ungate Checker to see which ones you're approved to sell.
4. Check retail prices, promotions, sales history, Buy Box share, and shipping costs to find profitable opportunities.

Let's say the paperback edition of I Will Teach You to Be Rich by Ramit Sethi sells for $20 on Amazon but $9.15 on Target.

Copy the product’s ASIN from Amazon and paste it into Boxem’s Bulk Ungate Checker to verify if you’re able to sell it.

If you’re gated, you can click “Ungate” in Boxem to check Amazon's requirements before ruling it out. For example, some books may only require a short questionnaire to become ungated. But if an invoice is required for approval, it’s time to move on.

If you're ungated, the next step is to check the retailer’s current promotions to lower your buy cost and boost your profit margin.

For example, a buy-one-get-one-50%-off deal at Target could cut each book's price by 25%. Stack that with a discounted gift card from a reputable site like CardBear, and you could turn an average sourcing opportunity into a profitable find.

Not every product you research will be a winner, but one good find can lead you to several more.

Make Sure the Numbers Work for FBM

Just because you're ungated and found a great deal doesn't mean a product is a good fit for FBM.

Always check both Buy Box competition and your expected shipping costs before buying inventory.

Start by using a tool like SellerAmp to review the product's Buy Box statistics. If FBA sellers consistently win most of the Buy Box, your FBM offer may struggle to compete. On a listing with steady sales, 20% or more of the Buy Box going to FBM sellers is a good sign.

Keep in mind that competition can shift during the holidays, too. A product that wasn’t FBM-friendly in October could become a much better opportunity in late November or December as FBA sellers run out of stock. Check historical trends and source inventory before demand peaks so you're ready when more FBM Buy Box share opens up.

Next, calculate your FBM profit correctly. Unlike FBA, FBM requires you to cover shipping for each order. Always use a profit calculator and include your estimated FBM shipping cost.

For example, shipping a product weighing around 6 ounces could cost $5-6. Factoring that in upfront helps you avoid overestimating your profit.

As a general rule, products priced above $20 and weighing less than a pound can be especially good FBM candidates because shipping costs are easier to absorb.

Even if FBA shows slightly higher profit, waiting weeks for inventory to check in could mean missing out on valuable sales. During Q4, sometimes getting an FBM offer live and selling today is worth more than waiting for Amazon to fulfill it.

Get Ready Before the Holiday Rush

You don't need to spend weeks getting ungated to make sales on Amazon. Start with brands you're already approved to sell, use storefront stalking to uncover sourcing opportunities, and check Buy Box history to find products that make sense for FBM.

With Q4 bringing increased demand and more opportunities for FBM sellers, now is the time to start sourcing. Use Boxem's Bulk Ungate Checker to find products you can sell, build up your inventory, and get ready to make the most of the holiday rush.
