If you sell through Amazon Vendor Central, managing POs is part of your everyday work. Many sellers, especially those with lots of products or services, find it hard to manage purchase orders by hand. The long term process includes receiving a purchase requisition, creating a purchase order, confirming it, preparing shipment, printing label, sending notification, tracking delivery status, and creating invoice. And on top of all that, you still have to follow Amazon’s rules and timelines, payment terms.
Mistakes in this purchasing process can lead to delays, chargebacks, unhappy partners, and lost revenue.
That’s why Windingflow built a complete purchase order system for Amazon sellers and vendors. It simplifies each step, removes manual work, and makes sure your business can respond quickly and accurately.
Quick and Simple Setup
Setup is easy and straightforward, so you can jump in without a developer. In just a few minutes, your Amazon blanket purchase order process can go live inside Windingflow.
Here’s what the setup includes:
- Add your Amazon PO account: Create an instance, select Amazon as your platform, and authorize with OAuth.
- Link warehouses: Assign shipping addresses and warehouse rules so the system knows where products come from.
- Add products and SKUs: Match your internal SKUs with Amazon platform SKUs to enable inventory management tracking and product matching.
After setup, new orders from Amazon will appear in Windingflow without you doing anything extra.
Bonus tip: If you’re working with multiple brands or regions, Windingflow supports multi-instance setup. You can split goods and services up by brand, region, or warehouse to make purchase orders work.
Manage the Full PO Process in One Place
Amazon expects fast action once a PO number is created. With Windingflow, your team can handle everything in one place.
Receive and Acknowledge Standard Purchase Orders Automatically
Every few hours, Windingflow pulls new POs from Amazon. Orders appear in a live dashboard where you can:
- View PO details at a glance
- Accept or reject line items
- See stock availability per SKU
- View reserved vs. available quantities
- Confirm quantities received
You can even partially accept orders—receive what you can now, and update the rest later. Windingflow tracks order status in real time: “New,” “Accepted,” “Partially Acknowledged,” “Rejected,” etc.
This helps your team move faster and avoid hold-ups.
Build and Manage Finished Product Shipments With Ease
Once contract purchase orders are accepted, it’s time to ship. With Windingflow, you can:
- Create shipments from the Order module or Shipments module
- Auto-fill address, shipping windows, and pickup dates
- Group multiple orders into one shipment when possible
- Edit shipment info anytime before packing
Shipments follow Amazon’s rules. Based on your inputs (e.g. cartons, pallets, paper based), Windingflow assigns Small Parcel or Less Than Truckload mode automatically.
Pack and Route Like a Pro
Once the shipment is ready, the system checks with Amazon for routing info. Then, it builds cartons and pallets using product dimensions and box rules.
Need to customize? You can:
- Adjust packaging sizes
- Add or remove cartons
- Reassign products across boxes
- Place cartons on pallets or remove them
Everything happens through a clean, visual interface designed for real-world warehouse use.
Download Labels and Ship Fast
Amazon requires accurate carton and pallet labels. With Windingflow, you can generate and download them instantly.
- Carton and pallet labels ready in one click
- Labels always match Amazon’s quantity rules
- Automatically submitted to Amazon after fulfillment is confirmed
No more back-and-forth or printing errors.
Smart Back-End Tools to Close the Loop
Send ASN (Advance Shipment Notification)
Let Amazon know your goods and services are on the way by submitting ASN directly through the platform. This keeps your metrics clean and prevents late-shipment flags.
Generate Invoices Automatically
Management process:
- Include or exclude items
- Add custom charges (e.g. shipping, handling)
- Export or submit invoices to accounting
Track Every Step
Your operations team can:
- Export shipment data for warehouse prep
- Import tracking info from your logistics provider
- Update tracking numbers with Bill of Lading (BOL)
- Push data to WMS or pull it back for syncing
Every status update is logged and visible, which means better communication across your teams.

A food company used Windingflow and went from spending 3 hours on each type of purchase order to only 15 minutes. They did it by letting the system take care of labels, shipping updates, and invoices.
