At Elzhen, as a trusted provider of refurbished probes and ultrasound machines, we now offer the option to submit your order and pay with a PO. In this article, we’ll walk you through how to submit a PO step by step.
What is a PO Payment?
A PO (Purchase Order) payment is a business-to-business payment process where a buyer places an order and, instead of paying immediately, chooses to pay with a PO. This means that when you use the PO payment method, you don’t need to pay by card or bank transfer at checkout. You can submit the order first and pay later based on the agreed terms. Recently, this payment option has also become available on Elzhen, allowing businesses to place orders more easily while keeping their usual purchasing workflow.
In practice, this process is based on an official document that a buyer sends to a seller (Elzhen) to confirm a purchase, including the items, pricing, and payment terms. It also contains a unique PO number for tracking. Once the seller accepts and confirms it, the PO often serves as a binding agreement for that specific order, and the buyer can receive the goods before completing the payment according to the agreed schedule.
Who Can Pay With a PO (Purchase Order)?
There are different payment methods available when buying online at Elzhen. While direct and online purchases (like paying by credit or debit card) are typically available to everyone, other options, such as the PO payment method, are usually reserved for specific types of buyers.
In most cases, the ability to pay with a PO at Elzhen is offered to customers who purchase through a formal procurement process, such as:
- Businesses and corporations (especially those with purchasing departments)
- Government agencies and public sector organizations
- Educational institutions (schools, colleges, universities)
- Hospitals and healthcare organizations
- Nonprofits and large organizations that require internal approval workflows
Because the PO payment method involves invoicing and payment terms, sellers often limit it to approved accounts or organizations with valid billing details. That’s why you may see “pay with PO” available only after verification, account setup, or meeting certain criteria (like minimum order value or business documentation).

Enter Your PO Number
Finally, enter your PO number to submit your order. Once uploaded, our team will review the details and process your order.
What Happens After You Submit a PO?
Once you pay with a PO, your PO request will be submitted, and within 1–2 business days, you’ll receive an email confirming whether your PO was approved or rejected.
If your PO request is approved, you can receive your product according to the delivery timeline discussed or shown at checkout. After the order is accepted and fulfilled:
- Your order is processed and delivered (digital delivery, shipment, or service scheduling, depending on what you purchased).
- Elzhen sends an invoice to you (usually your Accounts Payable team or billing contact).
- You need to pay the invoice based on the PO terms, which may include:
- agreed pricing and quantities
- payment timeline
- billing references (like PO number requirements)
- any other contractual conditions
So, while a PO isn’t an immediate “pay now” transaction, it is a formal commitment: the order is fulfilled, the invoice is issued, and the buyer completes payment in accordance with the PO terms.
PO Order Requirements & Terms
To pay with a PO, your PO number must be valid and issued by your organization’s authorized purchasing department. Your PO should also match the order details (such as buyer name, billing/shipping information, item descriptions, quantities, and agreed pricing) so it can be reviewed and approved without delays by Elzhen.
