Why do the sums in the quote and/or order differ slightly from the total or invoice sum?

In commercial practice, offer and invoice amounts are usually rounded up or down to two decimal places. This can lead to unexpected rounding differences in the cent range: Depending on whether the VAT amounts are rounded according to the horizontal method (at item level) or the vertical method (to the total amount), minor deviations between the final amount shown in the segment and the expected result are possible in individual cases.

Both calculations fulfil the requirements for invoices according to § 14 of the UStG and are therefore accepted by the tax authorities.

If the VAT is calculated and rounded at item level, the individual net prices and individual VAT amounts are added together, resulting in the individual gross amounts. These together then give the total gross amount. If the net prices are added up first and then the tax is calculated, the calculated and rounded amount results in the total gross amount. Although the amounts within the calculations are identical, there is a difference - this is not a calculation error. The different calculation methods (net calculation or gross calculation) lead to a slightly different result.

Bei Multiplikationen (Steuersatz, Rabette, Mengen ..) schlägt dies besonders zu Buche, wenn die Brutto/Netto-Einstellung nachträglich geändert wird. Vermeiden Sie das nachträgliche Umstellen!

Was the item price entered correctly

Für jeden Artikel können mehrere Preisschienen angegeben werden. Einige davon sind Bruttopreisschienen, andere Nettopreisschienen. Bei der Preiseingabe erscheint die einzugebende Spalte (z.B. „Netto“) in normaler Schrift, die abgeleitete Spalte (z.B. „Brutto“) in Kursivschrift.

If a net price bar is selected but gross prices are entered, this will result in rounding differences.

Achten Sie bei der Preiseingabe immer darauf, die Preise je nach Art der Preisschiene in der richtigen Spalte einzugeben.


Ist im Vorgang eine Nettopreisschiene eingestellt, aber die Option „Brutto“ aktiviert

In each operation, different price rails can be set independently and the option "Gross prices" can be activated. If a net price rail is set, which is thereby converted to gross prices, this leads to rounding differences

To have gross prices displayed, select a gross price rail in the segment.


Ist in der Spalte „Anzahl 2“ ein Wert mit Nachkommastellen eingegeben

If a very small value is entered under "Number 2" (e.g. 0.125), numbers with several decimal places result for both the price and the VAT. These decimal places are calculated but not displayed in the table. What is visible is an amount that has already been rounded to two decimal places. However, the total is formed with the decimal places and only then rounded, which leads to differences.

Avoid small values in the column "Number 2". If this is not possible, use component items or rounding difference items.

Create a separate revenue account for rounding differences, through which such amounts are settled for financial accounting purposes.


Gibt es mehrere Angebots- oder Bestellvorgänge, aber nur eine Rechnung

The total is rounded within individual transactions (quotation, order). However, if there are several transactions, these are summarised in the invoice and only then is the total rounded. This can lead to differences between the totals.

Create a summary segment for all quotations or orders to create the calculation based on the same total as for the invoice.
