The partial invoice

Strictly speaking, the colloquial term "partial invoice" stands for the more correct term "partial final invoice". This refers to the proper Accounting one or more services that have already been provided in full. With regard to the consequences for the financial accounting the partial invoice is therefore no different from a complete final invoice. Accordingly, this also applies to warranty obligations.

The partial invoice

On the other hand, the partial invoice, which is often used in the construction industry or plant construction, often contains a percentage of the services to be charged for a completed work or project. At the same time, this partial invoice, unlike the partial invoice, does not refer to explicit services or project phases. For example, the client of a plant must pay 30 % of the budget before the start of construction, which is requested via a partial invoice. Firstly, the type of invoicing naturally has no effect on the deadlines for warranties, in contrast to the partial invoice.

Correctly tax the partial invoice and partial invoice

Different tax rules apply to the two types of invoice. In principle, the obligation to pay the value added tax at the end of the pre-notification period in which the company provided the service. This applies to partial invoices and to final bills. However, if the contractor issues a partial invoice, the VAT is already due at the end of the pre-notification period in which the partial payment was received.

Correct final calculation

If an entire project is now completed, all services must also be invoiced with a final invoice. The project is thus "recognised in profit or loss". All advance payments for the completed work must be included in this invoice. This deposits naturally reduce the final payment.
