How to set up payment terms

Payment terms tell Viindoo when each part of an invoice is due. Go to Accounting ‣ Configuration ‣ Payment Terms, click New, name the terms and add one line in Due Terms for each installment: how much is due (a percentage or a fixed amount) and how many days after the invoice date. Then choose the terms on a quotation, an invoice or a contact, and Viindoo computes the due dates and splits the customer’s receivable by installment.

App	Accounting

Before you start

• Install the Accounting & Finance app.

• To choose payment terms on quotations, also install the Sales app.

How do I create payment terms?

1. Go to Accounting ‣ Configuration ‣ Payment Terms, then click New.

2. Type the Payment Terms name, for example 50% now, 50% in 60 days.

3. In Due Terms, add one line for each installment. For the first installment edit the line that Viindoo proposes; click Add a line for the next ones. Set Due (the value and Percent or Fixed) and After (the number of days and the date the days are counted from). The 30 Days terms of the picture have one line: 100 percent, 30 days after the invoice date.

4. Check the Preview: it shows how an example amount is split and when each part falls due.

5. Save the record.

You should now see the new terms in the Payment Terms list.

What do payment terms look like in practice?

Fixed amount first. An invoice of 10,000,000 ₫ dated 22 October 2026: 2,000,000 ₫ is due on the invoice date and the rest 30 days later. Add two lines: Fixed 2,000,000, 0 days after the invoice date, then Percent 100, 30 days after the invoice date. The first installment is 2,000,000 ₫ due on 22/10/2026; the second is 8,000,000 ₫ due on 21/11/2026.

Percentages. An invoice of 10,000,000 ₫ dated 22 October 2026: 50% is due on the invoice date and the other 50% after 60 days. Add two Percent lines of 50, at 0 and 60 days after the invoice date. The installments are 5,000,000 ₫ on 22/10/2026 and 5,000,000 ₫ on 21/12/2026.

Where do I use payment terms?

On a quotation

With the Sales app, choose Payment Terms on the quotation. Invoices created from the order take these terms by default.

On a customer invoice

Choose Payment Terms on the customer invoice or the vendor bill, instead of typing a Due Date.

After you confirm the invoice, open the Journal Items tab. Viindoo splits the customer’s receivable into one line per installment, each with its own due date.

On a contact

To use the same terms every time for a customer, open the customer in Contacts (or in Accounting ‣ Customers ‣ Customers), go to the Sales & Purchase tab and choose Payment Terms under Sales. For a vendor, use Payment Terms under Purchase.
