Incoming invoice to the point:
An incoming invoice is a document issued by the supplier that details the payment claim for goods delivered or services rendered. For purchasing, it is a central element of invoice verification and serves as the basis for checking prices, quantities and conditions as well as ensuring correct payments.
Example: An automotive supplier receives an incoming invoice for EUR 25,000 for 1,000 metal components, which is checked within 3 working days against the delivery bill, the order and the agreed conditions (2% discount for payment within 14 days) and approved for payment.

Introduction to purchasing controlling: Incoming invoice
What is an incoming invoice?
An incoming invoice is a document that a company receives from a supplier or service provider after a product has been delivered or a service has been provided. It serves as an official request for payment and contains detailed information about the delivered products or services, prices, quantities and payment terms. The incoming invoice is essential for accounting, as it forms the basis for recording liabilities and preparing for payment.
Core elements of an incoming invoice
Importance of the incoming invoice in purchasing
The incoming invoice is a central element in the procurement process, as it represents the conclusion of a purchase. It enables the purchasing department to compare the services actually received with the original orders and identify any discrepancies. Careful checking of incoming invoices contributes to cost transparency and prevents double payments or errors. It also influences liquidity management by controlling the timing of payments and taking advantage of possible discounts.
Efficient verification of incoming invoices
A structured check of incoming invoices ensures that payments are only made for correct and agreed services. It helps to avoid errors, control costs and secure the company's liquidity.
Practical example
Example: Checking an incoming invoice from supplier ABC GmbH
1. comparison with the order:
The invoice for €5,000 is compared with the original order no. 123456. Quantity ordered: 100 pieces at €50 each.
2. verification of the quantity delivered:
The delivery bill confirms the delivery of 100 pieces. The quantity matches the order.
3. control of prices:
The unit price charged is €50, as agreed in the contract.
4. checking cash discounts and rebates:
The invoice includes a 2% discount for payment within 10 days. This corresponds to the agreed terms of payment.
5. validation of the tax information:
The VAT of 19% is shown correctly(950 €).
6. approval and forwarding:
Once the invoice has been fully checked, it is released for payment and sent to the accounting department.
