arrange payment

I saw many people would write "Please arrange payment" on an invoice when they passed it to the accounts department for payment.

I wonder if we need to use an article before the "payment".

No.

'Please pay' would suffice.

I wonder if 'payment' is a countable noun in the above sentence. If it is, why don't we use a determiner before the 'payment'?

Grammar books say that we must use a determiner before a countable noun. Please help!

Having read the above definition, I think 'payment' is uncountable in your sentence.

Each department should have a rubber stamp saying 'Approved for payment' on invoices passed to the accounts department.

Alternatively, the accounts department should assume that all invoices passed to them have been checked and approved.

Thanks Mathew. Does def. no 1 "You can make a payment in any banks" not apply to my case?

In your sentence, 'payment' does not refer to an amount of money.
What will be arranged is to pay instead of an amount of money.

I agree with Matthew that the second definition covers the situation here.
