What is the Invoice Verification Process?
Invoice verification is making sure that the payment process has accurately been carried out. It also ensures that the vendor accurately bills the customers for the specific services or products they have utilized.
The invoice validation process is carried out by cross-checking the incoming invoices received against the purchase order and delivery receipt. An invoice is paid only if the invoice details match the supporting documents.

In case any essential invoice details are missing or if the invoice has any discrepancies, it is rejected and the vendor must be asked to generate a revised invoice.
Generally, companies have dedicated accounts payable managers who are authorized to verify and approve an invoice payment.
The main reason for invoice verification is to avoid any fraudulent payments. The invoice approval process varies. For small businesses, it may involve a simple review by the owner or manager. Larger companies often use automated systems or require multi-level approvals,
So, if you are wondering how to check invoice or which type of invoice verification you should practice, then let's talk about all the significant types of invoice verification.
How Does Invoice Verification Process Work?
To verify an invoice, businesses must carefully review the document to ensure accuracy and prevent making payments on erroneous charges. Key information contained in invoices like quantities, prices, and payment terms must match data from other sources such as purchase orders and delivery receipts.

Check invoice accuracy
Checking invoices accurately is the most vital step of invoice verification. Here is what you need to do to make sure that the invoice check process gets accurately conducted:
- Check if the invoice you received is meant for your company or not - vendors may mistakenly send an invoice to the wrong client
- Verify the rates of services/products to see whether they match the construction agreement
- Check whether the applied tax, discount, and final amount are correct
Confirm the invoice date
Checking the invoice dates has a massive significance in invoicing because it has many benefits, such as:
- It can make you lose or win legal battles about the transactions.
- It helps you avoid double payments.
- You can find invoices much easier if you want them later for auditing.
- You can calculate taxes more accurately with correctly dated invoices.
Confirm the delivery with the project manager
Confirming the delivery with the project manager keeps you away from fraudulent payments. Ensuring that you have received the services/products you are paying for is one of the best invoicing practices.
Before greenlighting the delivery, the manager has to check the described quantity and quality of the line items in the invoice with those of the actual delivery.
Sometimes, if the delivery is not made on time, the customer can pay less to the vendor and save the company money. This could only be possible by confirming the delivery with authority.
Check the vendor information
Checking vendor information is another easiest method to avoid fraudulent payments. You should cross-check the vendor details on the invoice with the past invoices in your accounts payable process. Check:
- Business name
- Logo
- Contact number
- Mailing address
- Email ID
- Bank details
This cross-checking not only warns you about fraud but also helps you keep your system data updated. And if it is a new vendor, you must verify the contact details before proceeding.
Moreover, if you want to save time and avoid payment failures, you should also check invoice payment terms like:
- Account number
- Tax ID number
- Preferred payment method mentioned on the invoice
Mark invoice due date
Making a note of the invoice due date helps you sort out the invoice payment priority and improve cash flow. Other than that, noting the payment deadline has economic benefits for your organization too.
It saves you from paying late payment fees and helps you avail of the early bird discounts as mentioned in the payment terms.
Schedule the payment
Once all the above essential invoice data are checked, the payment must be approved and scheduled by the accounting manager at least a couple of days prior. This gives you a window to stop the payment if there are any issues with the payment.
Moving ahead, in case if you are wondering about which type of invoice verification you should practice, then let's talk about all the significant types of invoice verification.
Alright then, let's jump right in.
Different Types of Invoice Verification
The invoice checking process depends on the nature of the trade. Also, the company size, company structure, and the process being followed affect the invoice validation process.
However, widely adopted business practices involve these three common invoice checking methods mentioned here.
Let's have a look at the three of them.

Invoice Verification Methods
| Method | Description | Best Used When |
|---|---|---|
| Purchase Order Based | The invoice is matched with the purchase order placed by the client's accounting department. This method counts only vital invoice details like total quantity and invoice amount, not partial deliveries. | You have a formal purchase order system and want to verify total amounts quickly |
| Goods Receipt Based | Individual goods are invoiced separately as they are delivered. Each delivery is verified against its corresponding receipt. | Goods delivery is done in parts and you need to track each partial shipment separately |
| Without Order Reference | Invoice is verified directly by the accounts payable authority, accountant, or G/L accountant when no purchase order number is available. | Purchase order numbers are not available or for non-standard purchases |
Now that you know the benefits of invoice approval, you must be eager to see the process. So let us continue!
