There are several ways to create a PO number on Amazon for your business.

  • Add an individualized PO number at checkout to your specific order or item.
  • Opt to have Amazon create PO numbers for every order.
  • Create a budget (blanket PO) for your business account.

Now, let’s learn how to create a PO number on Amazon through one of these three avenues.

Add an Individualized PO Number

In order to allow for individualized PO numbers to be added to specific orders, Administrators of business accounts on Amazon first need to change the account preferences to allow for the option to add a PO number on each purchase.

Here’s how to change the PO number preferences:

  1. Sign into your Amazon business account.
  2. Go to Business Settings.
  3. Select Business Order Info.
  4. Enable PO Number.
  5. Select Save.

From here, every time administrators or account users can enter a chosen PO number on the Amazon purchase order address line during checkout. The PO number should be a collection of numbers and characters that expresses one or more of the following descriptions:

  • List of items to be purchased.
  • Quantity of each item.
  • Price of each item.
  • Confirmed delivery date for each item or entire order.
  • Confirmed delivery location for each item or entire order.

Choosing a PO number that explains all the details of an order can be a challenge, which is why many business account holders opt to have Amazon automatically create and assign PO numbers.

Set Preferences for Amazon to Automate PO Numbers

To get the most out of the benefits that using PO numbers provides for your business, the best option is to have Amazon automate PO numbers on every order that can be organized and analyzed at the end of the fiscal month, quarter, or year.

To change the settings, so Amazon automatically sets a PO number for every order, here’s what you need to do:

  1. Sign into your Amazon business account.
  2. Go to Business Settings.
  3. Select Business Order Info.
  4. Enable PO Number.
  5. Select PO numbers are required for purchase.
  6. Select Save.

Once you have set this preference, the PO number can be found on every shipping label and packing slip, on invoices, and on your Amazon Business analytics report to keep your purchases organized!

Create a Budget PO

Amazon states that Budgets (Blanket PO) allow Account and Group administrators to create a purchase order with a budget for requisitioners at group and user-level.

This is a great option if you want to keep your budget in check while several users make purchases. When the budget has been spent for the specific time frame, no more purchases will be authorized.

Here’s how to create a Budget PO for your Amazon business account:

Group-level set-up:

  1. Under Your Account for Business, select Business Settings.
  2. Under Members, select Groups and then choose the group you wish to create a budget for.
  3. On the following page, under Billing & Shipping, select Budgets (Blanket PO).
  4. To create a new Blanket Purchase Order for this group, select Set up a new blanket purchase order.
  5. On the following page, enter the required information and select Save to set up your Budgets (Blanket PO).

User-Level set-up:

  1. Go to the Budgets (Blanket PO) page on your account.
  2. Under Allocations, select Add Allocation.
  3. From the drop-down, select Add individual or Add all group members.
  4. Enter the allocation amount in the Allocated column, or select Distribute funds evenly to allocate funds in batches.
  5. Select Save to save your changes once your allocation is complete.

Now you have all the information you need to decide which kind of PO number is best for your business account and, more importantly, how to create it!
