Purchase order tracking is the practice of following each purchase order (PO) from the moment it's issued until the goods are delivered, invoiced and the order is closed. Procurement, finance and IT teams use it to know what was ordered, what arrived and what is still pending. In IT, the trail runs one step further: every laptop, monitor or server on the order ends up as a device with a serial number that someone has to register in the inventory.
This guide covers purchase order tracking for IT hardware from the point where IT procurement has already issued the order. It lists the fields to record on every PO, the stages an order goes through, how to handle partial shipments and receiving, when a spreadsheet stops being enough, and how to turn received hardware into asset records.
What to track on every purchase order
A purchase order record is useful only if it holds the data each follow-up needs. These are the fields to record on every IT hardware PO and what each one is for:
| Field | What it’s for |
| PO number | The reference that ties the order to the vendor’s confirmation, every shipment, the invoice and, later, each asset. |
| Vendor | Who the order was placed with, which decides who to contact about late deliveries, returns and warranty claims. |
| Line items | Description, part number, quantity and unit price of each product: the baseline every delivery and invoice is checked against. |
| Expected delivery date | When each line should arrive, so a late shipment shows up before a new hire is left without a laptop. |
| Shipments received | Carrier, tracking number, ship date and units in each delivery, since one order often arrives in several boxes. |
| Serial numbers | The unique identifier of each unit received, needed for the asset record, warranty lookups and returns. |
| Invoice number | The vendor’s bill for the order or for each shipment, matched against what was ordered and received before payment. |
| Cost center | The department or budget that pays for the order, which should follow each asset into the inventory. |
| Linked asset record | The inventory entry created for each unit, which keeps the purchase history attached to the device for its whole lifecycle. |
Together, these fields answer the two questions behind most follow-ups: where an order stands and what is still missing. The next sections follow a PO through its stages, from issue to close, and show where each field gets filled in.
The stages of a purchase order, from issued to closed
Everything that happens before the order exists, from defining the need to choosing the vendor, belongs to the hardware procurement process. Tracking starts once the PO is issued, and most orders move through the same stages, even though each system names them differently:
- Issued: the PO is approved and sent to the vendor, with its line items, prices and delivery terms.
- Acknowledged: the vendor confirms the order, the prices and the expected delivery dates, or flags lines it can't fulfill.
- Partially shipped: part of the order is on its way, and the rest is pending or on backorder.
- Received: everything on the order has arrived and was checked against the PO.
- Invoiced and matched: the vendor's invoice was compared with the PO and the receiving record, and approved for payment.
- Closed: no line has anything pending, and the order stays on file as part of each asset's purchase history.
An order can also end as cancelled, in full or line by line, when the vendor can't deliver or the need disappears. Keeping the status current at each stage turns "where is my order?" into a quick lookup instead of an email thread with the vendor.
These stages describe the process in general terms, so a procurement or Asset Management tool may use other names for them or combine several into one status.
Partial shipments and backorders
Hardware orders rarely arrive in one box. Vendors ship from different warehouses, some models go on backorder, and large orders for a rollout often go out in waves, so a single PO can produce three or four deliveries over several weeks.
The way to keep that under control is to record each shipment against the order's line items: for every line, how many units were ordered, how many shipped and how many were received. A backordered line stays open with its pending quantity, and the PO isn't closed until every line is received or cancelled. Recording the tracking number of each shipment also helps when a box reaches reception without a packing slip that says which order it belongs to.
Receiving IT hardware against the purchase order
Receiving is the step where what was ordered meets what actually arrived. Before signing for a delivery or storing the equipment, check it against the PO:
- Quantities: count the units of each line item and compare them with the quantity shipped and the quantity ordered.
- Models and part numbers: confirm the vendor sent the configuration on the order (memory, storage, keyboard layout), since a substitute model changes pricing and support.
- Serial numbers: record the serial number of each unit and compare it with the packing slip or the vendor's shipment notice.
- Condition: note damaged boxes or units before accepting them, because return windows are short.
Any difference goes on the receiving record the same day and is reported to the vendor while the order is still open. Units that pass the check are ready to be registered as assets.
Three-way matching before payment
Three-way matching compares three documents before an invoice is paid: the purchase order, the receiving record and the vendor's invoice. If quantities, prices or models don't match across the three, the invoice is held until the difference is resolved.
For IT hardware, the receiving record is where the serial numbers live, which makes it the document finance and IT share. When it's accurate, the vendor gets paid for what actually arrived, and the same data feeds the asset records in the next step.
Spreadsheet vs system: when purchase order tracking outgrows Excel
Most of the templates that come up for purchase order tracking are spreadsheets, and that's where many IT teams start. A spreadsheet does the job while orders are few and simple:
- A handful of orders per month, each from one vendor.
- Orders that arrive in a single delivery.
- One person who owns the file and keeps it updated.
It starts to break when the order has to connect with what happens after delivery. These are the usual signs that it's time for a system:
- Orders that arrive in several shipments, with pending quantities per line.
- Serial numbers that have to be typed again into the inventory.
- Several people updating status, receiving and invoices in the same file.
- Assets whose purchase order, cost or vendor nobody can find a year later, during an audit or a warranty claim.
From purchase order to asset record with InvGate Asset Management
The step that procurement guides leave out is registering what arrived as an asset, with the purchase data attached. InvGate Asset Management is IT Asset Management software that offers an enterprise experience without the complexity or the price of one. Purchase orders are a native record type in it, with line items, shipments and financial details, so the order and the assets it produces live in the same system.
Track every shipment against the order
Each purchase order can hold multiple shipments, from any vendor. A shipment records the carrier, tracking number, ship and delivery dates, invoice and shipping address, plus the units of each line it contains.
For every line, the order shows how many units were bought, how many were shipped and how many assets were already created. Partial deliveries and backorders are visible on the order itself, and the team updates its status as it moves forward.
Create assets from what arrived
When hardware arrives, the team records what was received from the order's items and creates the assets in bulk, delivery by delivery, without waiting for the order to be complete. Each asset is created with the purchase data the order already holds:
- Serial number
- Acquisition cost, taken from the unit price of the line
- Acquisition date, taken from the order date
- Cost center
- Part number and shipment invoice
- Purchase order and vendor
Assets that already exist in the inventory can be linked to their purchase order as well. Software, services and warranties bought on the same order appear as lines but don't become assets, and for Dell, Lenovo and IBM devices the serial number lets the Warranty APIs integration fill in the warranty expiration.
Bring orders in without retyping them
Line items can be loaded from a CSV file, which saves time when a vendor quote has dozens of lines. Any order can be downloaded as a PDF to share with the vendor or route through an internal approval, and teams whose source of truth is an enterprise resource planning (ERP) system can create and read purchase orders through the API.
Purchase orders with multiple shipments are part of a recent release. General availability may vary: contact your Customer Success Manager to request access if the feature isn't available in your instance.
Importing purchase orders from your IT reseller with InvGate Asset Management
Many organizations buy hardware through a reseller, and the reseller already holds the data IT types by hand: the order, the serial numbers and the invoice. CDW, one of the largest IT resellers in the United States, connects to InvGate Asset Management so its orders reach the inventory without manual entry.
The integration follows the order from confirmation to delivery. This is what it brings in at each step:
- Order confirmed: the purchase order is created with its line items and prices. Orders placed directly on the CDW website arrive with the first shipment.
- Shipment dispatched: each delivery is added to the order with its carrier, tracking number, invoice and units shipped.
- Hardware received: the team creates the assets from the order, with the serial numbers CDW reported already filled in and editable if a unit doesn't match.
When a box arrives, pasting its tracking number in the purchase order explorer finds the order it belongs to. The integration is set up together with the CDW Account Manager and the InvGate team, and it brings in the orders CDW confirms or ships after activation. It's part of the same recent release, so the same availability note applies: your Customer Success Manager can request access if you don't see it.
Conclusion
Purchase order tracking for IT hardware works when every order can answer three questions: what was ordered, what arrived and where each unit ended up. A PO record with line items, shipments, serial numbers and invoices answers the first two, and the link to the asset record answers the third, keeping the purchase history at hand for audits, warranty claims and refresh planning.
If your team still copies serial numbers from packing slips into the inventory, start a free trial of InvGate Asset Management to create assets directly from your purchase orders. You can also talk to Sales to see how the CDW integration fits the way you buy hardware.
Frequently Asked Questions
These are short answers to the questions that come up most when teams start tracking purchase orders. Each one summarizes a part of this guide in two sentences or less.
How do I track a purchase order?
Record the PO number, vendor, line items, expected dates, shipments, serial numbers and invoice, and update the status at each stage from issued to closed. A system that links each delivery to the order shows what's pending without chasing the vendor.
What is the difference between a purchase order and an invoice?
The buyer issues the purchase order to state what it agrees to buy and at what price. The vendor issues the invoice to request payment for what was delivered, and it's checked against the PO and the receiving record.
What happens when a shipment arrives incomplete?
Record what arrived against each line item and leave the missing units open as pending or backordered. The PO stays open until every line is received or cancelled, and the invoice is paid only for what was received.
How do you link a purchase order to an asset?
Create the asset from the PO when the hardware arrives, so it inherits the order number, vendor, cost and serial number. Assets already in the inventory can be linked to their order from the asset record.
What is a partially received purchase order?
It's an order where some units or lines have arrived and others are still pending. It's common with IT hardware, because vendors split large orders across several shipments.
