Ins and Outs of Flat Rate Shipping 

Flat rate shipping is a technique for deciding how to price your shipping. When you charge a fixed rate for every order, it becomes easy to track and manage expenses. Whether you fulfill orders in-house or outsource to a 3PL, you can inculcate the flat rate method for your customers. 

All major shipping carriers like FedEx, USPS, and UPS, have a different flat-rate shipping program. Opting for the best of them can be a tough choice. But before you decide that, let’s understand what the flat rate method is and if you should use it for your eCommerce business or not. 

What is Flat Rate Shipping?  

Flat rate shipping is a type of shipping where the rate is based on the size of the box. Therefore, any weight can be shipped at the same price, as long as it stays under the box’s maximum weight. Hence, in one price slab, you can ship heavy as well as lightweight packages. 

Due to the nature of this kind of shipping, it is known as Linear Rate. Irrespective of the weight, size and other dimensions, a linear shipping rate applies to all types of shipping boxes and packages in the same slab. Therefore, shipping heavy parcels are more beneficial than smaller ones in flat rate shipping. 

Difference between Flat Rate Shipping and Standard Shipping  

The common factor in both of them is that they both are pricing strategies for shipping your orders. But they are different in many ways. 

As the name suggests, standard shipping is the general shipping method in which the price is based on destination location and distance, box dimensions, and weight. It is a pricing strategy that is used for longer or un-prioritized deliveries. The delivery time for standard shipping can vary depending on the packages and can be anywhere between 5-15 days. 

Flat rate shipping is the type of shipping where the buyer pays a fixed price for any item that ships within a weight slab. It can vary according to different shipping zones. For example, the flat rate may differ according to the location and the zone where the item needs to be shipped. Moreover, there is a predetermined delivery time in the flat rate method that cannot be altered.

Factors affecting Flat rate Shipping Method  

Factors affecting Flat rate Shipping Method

Now that it is clear that flat rate shipping is affected by the weight, time zone, and box dimensions, let’s dive into each factor in detail. 


The weight slab is decided by the seller or the shipment companies under which the flat shipping rate is applied. For example, the slab can be set to 50 pounds, as FedEx does. Then, all the boxes or parcels below that weight are eligible for a flat rate. The slab is always set to make matters simple. 

Time Zone 

One factor that you must consider while providing a flat shipping rate to your customers is time zone. Shipping costs differ with the time zone. If the destination time zone is closer to your location, shipment prices will be lower as well. Conversely, the farther the time zone, the costlier the shipment. Hence, having multiple customers of the same time zone is definitely an advantage for you. 


Generally, shipping companies have a fixed size for boxes. This way, they keep the shipping process smooth and consistent. Moreover, they have containers of the specified dimensions. And flat rate method can have a specified dimension or slab to ship the parcels. 

Advantages of Flat Rate Shipping

Advantages of Flat Rate Shipping

The basis of the flat rate method is that it is ideal for everyone under the same time zone, weight, and dimension slab. So now let’s have a look at some advantages of it. 

Clarity and Transparency 

When you provide flat rate shipping to your customers, it brings them clarity for your selling mechanism. In addition, it establishes transparency in pricing between you and your customer because of the fixed shipping price and no additional or hidden costs. This clarity and transparency help you gain trust among your consumers. 

Simplified Management 

Smooth management of every process in the business is essential for it to be successful. Unlike standard shipping, you save a lot of time in flat shipping by calculating a pre-defined price for different slabs. Hence, the process in the flat rate method is simplified. Additionally, you don’t need to add a shipping calculator to your eCommerce website.

Less Errors and Quick Response 

When products are shipped using standard shipping, there are a lot of calculations. Most time is spent calculating shipping costs by measuring tons and tons of boxes’ weight and dimensions. Not to forget, this has a probability of human errors. All such errors have less chance to occur in the flat rate method because of a fixed price. 

Consistency in Pricing 

The one advantage of the flat rate method is consistent pricing. No matter the weight or dimensions of the parcel, it is the exact price under the same slab. Hence, flat rate shipping makes it easy to calculate shipping charges along with saving time and effort. However, before you opt for any logistics partner, check the kind of slabs they have set for different factors. 

Should I use Flat Rate Shipping?

Flat rate shipping has many advantages that make it an appealing service for eCommerce businesses. First, you are well aware of the costs when you ship in a flat rate box. Second, there is no need to use the shipping price calculator plugin on your website because of the fixed price. Hence, to save time on shipping calculations, the flat rate method is one of the best choices. 

For small businesses, the flat rate method can generate huge savings because of the lower, predictable cost. Of course, it doesn’t make sense for every eCommerce business to use flat rate shipping because of different operating methods, but often, small business owners find it profitable. 

Therefore, if you are starting out and find the flat rate method to be profitable for your business, then it’s time you start implementing this pricing strategy. 

Does Flat Rate Shipping save you money? 

It depends. You might save money in flat rate shipping when: 

  • You charge your customers a fixed rate for shipping. 
  • Your products are relatively small and heavy. 
  • You don’t ship many orders and own your order-fulfillment process. 

Saving money becomes easy with low order volume. However, once you grow enough to outsource your eCommerce fulfillment, you need a full-fledged fulfillment strategy.
