Someone has told me that when you invoice a company, payment within 30 days is the standard legal requirement.
I'd never heard of this, TBH, but what they are saying is that if the company wants to offer other terms they must do so at the time of awarding the contract to you, otherwise the legal position is they pay in 30 days- after which you can add interest/late payment fees.
This query relates to one particular type of work, but the person who told me this implies the 30-days rule applies to all payments, any business.
Is this right?
