In the construction industry, partial invoices are widely used. Construction projects usually extend over a certain period of time, and, taking into account the expected progress of construction, acceptance and correspondence payments are agreed in advance invoices. A down payment invoice, which the customer pays before beginning construction, is also common.
In other trades and in factory construction, partial invoices are used above all when longer-term projects are involved. Here, too, down payments before the start of the project are not uncommon, which is usually followed by an interim invoice as soon as the first agreed service has been rendered and accepted.
However, partial invoices are also not uncommon for other types of orders in many industries: self-employed people who carry out long-term orders often agree on partial invoices with their customers in order to secure a regular income. In return, clients agree to advance invoices with companies in order to better plan their payments over time. This means that both sides often benefit from an even cash flow in partial amounts.
