But, as a small company/start-up you should absolutely stand firm on 30 day payment, 45 at the most. It's completely ludicrous that large companies cannot pay in reasonable time-frames - it's just bullying, and is only done so that the large company can conserve cash. Most small businesses fail because of cash, and failure to pay by large customers is a big reason they get overstretched.
