This guide will help you get started, understand the basics of Amazon selling, and explain in simple words how it all works.

Managing supplier orders without a system is one of the fastest ways to stall your Amazon wholesale business. Whether you’re running bulk online arbitrage, wholesale, or dropshipping operations, you need a structured way to request and track inventory – and that starts with a proper Amazon FBA Wholesale Purchase Order. 

A PO isn’t just a document; it’s your control panel for cost, quantity, and delivery accuracy. 

In this post, we’ll walk you through what a strong purchase order should include, share a template, and show how Seller Assistant helps you create, send, and manage POs automatically – without the spreadsheet chaos.

Why Create an Amazon Purchase Order

A purchase order (PO) is a formal document created by the buyer – you, the Amazon seller – and sent to a supplier to request products under agreed terms. It includes the items you’re ordering, quantities, unit prices, delivery instructions, and payment details. A PO acts as a binding agreement that outlines what you expect to receive.

Unlike invoices (which are issued by the supplier), a PO originates from you and signals a clear intent to purchase. It protects your business by reducing miscommunication, tracking expenses, and keeping your sourcing organized – especially when you scale.

Who needs to create a purchase order?

Any Amazon seller who buys products in bulk or repeatedly works with suppliers benefits from POs. 

Sellers who need POs

  • Wholesale sellers ordering catalog products at scale
  • Online arbitrage (OA) sellers buying from bulk price lists
  • Dropshippers coordinating fulfillment with external suppliers
  • Hybrid sellers doing a mix of all of the above.

Even if you’re not at high volume yet, building the habit of using POs early makes scaling smoother and safer.

Reasons to create a purchase order

Keep your orders organized

POs help you track what was ordered, in what quantity, at what cost, and from which supplier. No more digging through emails or versioned spreadsheets.

Reduce costly errors

By specifying exact ASINs, SKUs, and delivery locations, POs reduce the risk of receiving wrong or mislabeled inventory – especially when using prep centers.

Streamline communication

Suppliers know exactly what you expect. There’s no back-and-forth over missing details, and it speeds up fulfillment and invoicing.

Build a clear reorder history

Each PO acts as a historical log. When it’s time to restock, you know exactly what you ordered, how much you paid, and when it arrived.

Calculate true cost of goods sold

POs allow you to track all costs tied to sourcing – including shipping and taxes – which gives you a more accurate COGs for repricing and profit analysis.

Create accountability in your team

For sellers working with virtual assistants (VAs), POs act as a source of truth. No duplication, no miscommunication – just one documented workflow.

Protect yourself in disputes

If a supplier delivers the wrong item or under-ships, your PO becomes a written record of what was agreed. It’s your proof if things go wrong.

What Should an Amazon Purchase Order Include

A well-structured Amazon FBA purchase order template ensures accurate communication with suppliers and prep centers. Below are the key elements every PO should contain – whether you create it manually or using a tool like Seller Assistant.

Buyer and supplier contact details

Include full company names, addresses, phone numbers, and email contacts for both parties. This prevents delays with invoicing, customs, or fulfillment issues.

PO number and issue date

Assign a unique PO number for tracking and follow-up. Include the date the order was issued so both parties can refer to the correct version.

Product identifiers: ASINs, titles, SKUs, and quantities

For each product, list the Amazon ASIN, product title, internal SKU (if applicable), and quantity. This level of precision reduces pick/pack errors and helps with prep center coordination.

Unit pricing and line totals

Specify the price per unit and calculate the total per line item. This ensures suppliers can verify totals and lets you track ROI and margin clearly.

Shipping and billing addresses

Clarify where the goods are going (your prep center or warehouse) and where the bill should be sent. Mistakes here can cause costly reroutes.

Payment terms and method

Document whether you’re paying via Net 15, credit card, wire transfer, or other methods. Include due dates and any applicable discounts (e.g., for bulk or prepayment).

Tax, shipping, and additional charges

Add line items for sales tax (if not wholesale exempt), shipping costs, and any extra fees like rush handling. This helps calculate true landed cost.

Internal notes and supplier instructions

Use this field for prep requirements, delivery deadlines, minimum order quantity notes, or instructions like “apply FNSKU labels” or “bundle SKUs.”

Why Manual Purchase Orders Don’t Scale

Creating your own purchase orders in spreadsheets or Word documents may work when you’re placing a few test orders. But as your Amazon business grows – more suppliers, more SKUs, more team members – manual PO workflows become a bottleneck. Here’s why.

Repeated data entry leads to mistakes

Copying and pasting ASINs, SKUs, prices, and quantities across files creates opportunities for human error – especially when rushed or done by a virtual assistant.

No version control

When POs are saved in email threads or local folders, it’s easy to lose track of which version is final – or if it was even sent. This causes delays, double orders, and confusion during reorders.

Hard to trace product sourcing

If you’re analyzing a price list, finding winning products, and then manually typing them into a PO, you lose traceability. Later, it’s unclear where a product came from or what its profit metrics were.

No live order status

Manual POs don’t track whether an order is sent, received, or partially fulfilled. You’ll need yet another system (or memory) to figure out what’s pending and what’s complete.

Prep centers rely on accurate POs

If you’re using a prep center, the PO is often the only document they see. Any mismatch in SKUs, quantities, or delivery instructions can delay check-in or create labeling errors.

Not scalable for teams

When you have multiple people sourcing, buying, or managing supplier relationships, everyone needs a single source of truth. Spreadsheets don’t support collaborative or role-based workflows well.

How to Create a Wholesale Purchase Order with Seller Assistant

Creating a PO manually might take 30–60 minutes. With Seller Assistant, it takes just a few clicks – and every key detail is pulled from your saved records. Here’s how the process works.

  • Step 1. Choose a supplier

Start by selecting a supplier from your Suppliers Database or entering a new one. Seller Assistant automatically fills in address, contact info, and payment terms.

Choose a supplier from your Seller Assistant Suppliers Database.

  • Step 2. Click “Create PO”

This opens a new draft purchase order with a unique PO number, issue date, assigned team member (optional), and pre-filled supplier and buyer details.

Click “Create PO”

  • Step 3. Customize the draft

Review the pre-filled PO. You can update the PO number, assign a team member responsible for the order, and choose the correct prep center or warehouse from your Warehouses Database.

You can change the PO number if needed, assign the responsible team member, and select the correct warehouse from your Warehouses Database in Seller Assistant.

  • Step 4. Add products
    • You have three ways to add products:
      • From Price List Analyzer – select winning items from a scanned price list

Click “Add products” and add products from Price List Analyzer (PLA)

  • From supplier records – reuse previously saved products
  • From scratch – add products by ASINs, UPCs, or titles (e.g. for Keepa finds or test buys)

Add products to PO from scratch/manual entry – add products by ASIN, UPC/EAN, title, or brand

  • All fields are auto-aligned and duplicates are flagged automatically.

  • Step 5. Set costs, tax, and shipping

Adjust quantities and unit costs as needed. Add shipping and tax (if applicable). The PO will calculate subtotal, taxes, and total due in real time.

  • Step 6. Review and export

You can review the PO, then export it in PDF or XLSX format for emailing to suppliers. All POs are saved and searchable for future use.

Export PO

  • Step 7. Track PO status
    • Each PO has a live status:
      • Draft – still editing
      • Sent – order placed
      • Completed – fully received
      • Canceled – archived or voided
    • This helps your team stay aligned and prevents accidental duplicate orders.

Monitor each PO as Draft, Sent, Completed, or Canceled inside the module.
