What are undisputed invoices?
An undisputed invoice is an invoice your client has not protested.
No protest means your client has not challenged the invoice on its merits. Not in writing, not verbally. They simply do not pay, without giving a valid reason.
What counts as a dispute?
A dispute is any reaction in which your client challenges the invoice on its merits. For example: they disagree with the amount, the work delivered, or the agreed terms.
Important: a dispute can be made in writing or verbally. It does not have to be justified, and it does not have to follow your general terms and conditions.
In other words: even if your terms state that a client may only protest within 8 days and only by registered letter, a protest outside those rules still counts as a dispute. A phone call or an email is enough.
And a partial dispute?
If your client disputes only part of the invoice, the rest remains undisputed. If that part has been corrected, for example through a credit note, the remaining amount can still be recovered through the IOS procedure.
