How to configure the cash rounding method

Use cash rounding when the total of an invoice must be a multiple of the smallest coin or banknote that customers really pay with, for example 1,000 VND. Enable the feature in Accounting ‣ Configuration ‣ Settings, create a rule in Accounting ‣ Configuration ‣ Management ‣ Cash Roundings, then choose the rule in the Other Info tab of a draft invoice. Viindoo rounds the total and records the difference, either as a separate Rounding line or inside the biggest tax.

Who	An accounting administrator enables the feature (Settings). Users with the Invoicing access right create the rules and apply them to invoices.
App	Accounting

Before you start

• Install the Accounting & Finance app.

• Know the profit and loss accounts that will receive the rounding difference, for example 711 Other income and 811 Other expenses of the Vietnamese chart of accounts.

• Cash rounding is applied to a draft invoice. See How to create a customer invoice.

How do I enable cash rounding?

1. Go to Accounting ‣ Configuration ‣ Settings.

2. In the Customer Invoices section, tick Cash Rounding, then click Save. The Cash Roundings menu now appears in Accounting ‣ Configuration ‣ Management.

How do I create a cash rounding rule?

1. Go to Accounting ‣ Configuration ‣ Management ‣ Cash Roundings and click New.

2. Fill in the rule (see the table below). For example, to round the total up to the next 1,000 VND by adding a line: Rounding Precision 1,000, Rounding Strategy Add a rounding line, Rounding Method Up, with a profit account and a loss account.

3. To put the difference in the tax instead of a separate line, choose the strategy Modify tax amount. The profit and loss accounts then disappear from the form, because the difference goes into the account of the biggest tax.

Which fields matter in the rule?

Field	What it affects	If left empty or wrong
Name	The name you choose on invoices. With the strategy Add a rounding line it is also the label of the rounding line.	Required.
Rounding Precision	The smallest amount that the total must be a multiple of (for example 1,000 for 1,000 VND).	It must be greater than 0: Please set a strictly positive rounding value.
Rounding Strategy	Add a rounding line: Viindoo adds a Rounding line to the invoice. Modify tax amount: no line is added, Viindoo changes the biggest tax of the invoice.	Modify tax amount does nothing on an invoice without tax.
Profit Account	The account that receives the difference when the rounding increases what the customer pays. Shown, and required, only for Add a rounding line.	Empty: the field stays red and you cannot save the rule.
Loss Account	The account that receives the difference when the rounding decreases what the customer pays. Shown, and required, only for Add a rounding line.	Empty: the field stays red and you cannot save the rule.
Rounding Method	How the total is rounded to the precision (see below).	Required.

Rounding Method	Rule	Total of 407,405 with a precision of 1,000
Up	Always rounds up to the next multiple of the precision.	408,000
Down	Always rounds down to the previous multiple.	407,000
Nearest	Rounds to the closest multiple: up when the remainder is half of the precision or more, otherwise down.	407,000

How do I apply a cash rounding rule to an invoice?

1. Open a draft invoice (or create one in Accounting ‣ Customers ‣ Invoices).

2. Open the Other Info tab and choose the rule in Cash Rounding Method.

3. Click Confirm. The invoice keeps the rounded total.

What does an invoice look like with each strategy?

The two examples below use the same kind of invoice, with a 10% tax, and a rule that rounds up to 1,000 VND.

Add a rounding line

The invoice has 3 units at 123,456 VND: untaxed amount 370,368, tax 37,037, so 407,405 before rounding. The totals block shows a Rounding line of 595 and a Total of 408,000. The line is recorded in the profit account of the rule.

Modify the tax amount

The invoice has 3 units at 133,456 VND: untaxed amount 400,368, tax 40,037, so 440,405 before rounding. There is no Rounding line: the tax of the invoice becomes 40,632 and the Total is 441,000.

Note

Rounding down is also possible: with the method Down, the same 407,405 becomes 407,000 and the difference of 405 is recorded in the loss account.

Expected result

• The total of the invoice is a multiple of the rounding precision.

• With Add a rounding line, the journal entry has one more line, in the profit account (rounding up) or the loss account (rounding down). With Modify tax amount, the tax line itself changes.

Common errors

Message or symptom	What to do
Please set a strictly positive rounding value.	Enter a Rounding Precision greater than 0.
The Profit Account or the Loss Account is red and the rule is not saved.	Fill in both accounts, or choose the strategy Modify tax amount, which needs none.
The Cash Roundings menu does not appear.	An accounting administrator must tick Cash Rounding in Accounting ‣ Configuration ‣ Settings.

Next steps

• How to process a cash discount: give a discount when the customer pays early.
