Which plugin I should use? USPS or

If you are looking at leveraging USPS shipping then you have two options. Either work with USPS directly or get USPS rates through (As per their online postage service simplifies access to the lowest USPS shipping rates). WooForce has separates plugins for integration with USPS and With the USPS Plugin you need to manually pay the postage after printing the label. This is because USPS don’t usually share the API to pay postage. But if you need to completely automate the process by paying postage from your WooCommerce Order page, you can use our plugin. Please refer below table for a comparison of both the plugins. You only need to buy one of these plugins depending on whether you need automatic postage payment or not.

    I have to say that this developer has excellent response time to any issues. The plugin works great and adds a lot of functionality to the shipping process.

    Mark and his team of supporters have been very helpful and respond fast. They answered a lot of my question prior, directed me to who I needed to talk to. Ofcourse being tech literate helped too but they were very helpful throughout the whole process. Now I am able to ship packages at home, slap a paid label and postage using the plugin. Also, I tried the normal plugin originally but support easily switched me to the postage plugin with no issues upon request. Everything works with my woocommerce. Thanks support team! Longest review I’ve written!

    Amazing support! They helped me get setup late at night and were extremely helpful in their support!

    But this plugin! It will pay itself off with the time saved of individually making labels!

    I was angry for 2 hours because I didn’t read the damn instructions. Make sure to remove other shipping methods, as they took default over this. However, in the last 4 hours of operation, we got it dialed in and now we have our trained monkey (me) printing orders and getting everything done in such a pace that I might see my family today.

    I have bought a couple of plugins from WooForce including this with USPS postage. Their customer service is outstanding. They are quick to respond to questions and concerns, and if needed, they work with us on our servers to address any configuration issues. Plugin works as documented. We originally bought the stand alone API plugin. Then decided to go with this plugin This plugin shows the live shipping rates online, allows us to hide postage and automatically print the postage for the shipping service that customer chose during checkout. We have been very happy with the plugin and the tech support.

    Wooforce support has been outstanding! I was challenged with accurately configuring the weight and dimension calculation for multiple items in cart to fit in one box and calculate accordingly. Support took the time to understand my products and how best to recommend the correct settings. The solution was correcting the inner dimension of the box. This plug in now calculates USPS shipping costs based on user address accurately. Thanks Wooforce for your patience in helping figure this out for me.

    No priority mail flat rate boxes are showing up at all. All I get is the padded envelope and then if enough product is added it says there's no shipping option to choose from. I have Priority Mail Flat Rate Medium and Large boxes "enabled" under box dimensions, and I also have them checked under services. What am I missing?

    The plugin needs to be debugged and figure out why its not playing nice with woocommerce 3.3, i would advise no one to update woocommerce until this issue is figured out. In short, with the plugin enabled with WooCommerce 3.3 anytime trying to edit or add a post you get Error 500.

  • Christine

    When I use the shopping cart to check out, the plugin lists the shipping options in a peculiar order, with the most expensive option listed in the middle. Is there a way to reorder the shipping options so they are listed from cheapest to most expensive? Also, the titles on the shipping options don't indicate how long each one takes, which seems like essential information. Is there a way to display shipping times?

  • Anindo

    Anindo - 2 weeks ago

    Hi Christine, Thank you for reaching out to us. Unfortunately, there is no option available to reorder the shipping options so they are listed from cheapest to most expensive. However, you can re-order the services manually such that say Priority Mail shows at first and then the rest of the services. For this, just drag the service and place it in top of the service column. Also, delivery estimate feature is currently not available in Stamps. However, we can implement this feature if Stamps supports this.
