Advantages of using USPS for your eCommerce shipping needs

USPS is one of the top delivery options in the US, and they have specially designed services suitable for business customers. In fact, this gives you the choice to pick a suitable service considering the unique business scenario that you are encountering. Moreover, USPS has business-friendly services like ‘Free Saturday Delivery’ and ‘Surcharge Free Residential Delivery.’ And whenever, you need help, you will get it from the experts of USPS. Here is a quick look at some of the reasons why USPS is widely preferred as a delivery network.

Economical pricing

For eCommerce businesses big and small, shipping can be one of the major factors that determine success and cost-effectiveness. When you compare the rates of USPS with some of the other leading shipping carriers, you can find an advantage in most cases. USPS can give competitive rates for their services, as the sheer volume of shipments they handle on a day is huge. Moreover, you will find time-specific delivery options in Priority and Express Mail, which is, in most cases, better than its competitors’.

Transparent Pricing

USPS offers one of the most transparent pricing systems in the shipping industry. For example, when most of the other carriers levy a surcharge on Residential Delivery, there is no such cost with USPS. At the end of the day, you will have a better hold of your shipping expenses with USPS and WooCommerce. This way, USPS adds a lot of value to the shipping needs of businesses of all sizes and types.

Services for faster delivery

USPS offers a great range of services that ensure quicker delivery of shipments across the country. If you choose Priority and Express Mail to USPS, you can expect a pretty fast delivery. This is an important aspect for an eCommerce store owner, as faster delivery always promises better customer satisfaction.

Flat rate shipping options

USPS offers the best flat rate shipping options for your shipments. Basically, when you are shipping heavier objects that takes only less space, USPS flat rate boxes can be of great advantage. Basically, the weight of the product won’t be considered to determine shipping charges and it can prove to be a cost-effective solution. You can reap the full benefits of USPS flat rate boxes if you have several heavy but small sized products in your store.

Better dimensional weight calculation

Similar to the above scenario, if you are mostly shipping lightweight products, USPS can still be a better choice. When most of the other shipping carriers have dimensional weight pricing, this calculation applies only to USPS shipments more than one cubic foot.

PO Box delivery

USPS offers PO box delivery, which is kind of an exclusive priority in the US. Other shipping carriers also offer PO box delivery, but it is actualized by a collaboration with USPS. Similarly, USPS is the only option when you want to deliver products to military addresses.

Free pick-up

USPS offers free pick up of packages from your address. This is applicable to a select range of products. However, if you want to schedule a pick up at a specific time window of your choice, you will have to pay extra. If the regular pick up option suits you, then it is a great way to save some money on pickup costs. You can find quite a few small businesses that save considerable amounts this way.

Volume discounts

For your commercial packages, you can get discounts based on the volume. However, all these commercial packages have minimum requirements. You can also use one of the approved shipping consolidators to avail volume discounts. In addition, these shipping consolidators help you to sort, pickup, and manifest your package. This way, you will have lesser hassles to calculate, document, and pay for postage.

Free shipping supplies delivery

For services such Priority Mail, Priority Mail Express, and Priority Mail Express International, USPS offers free delivery of shipping supplies. However, you should note that this facility is available only domestically.
