You might want to look into preferential shares or options in regards to per-project basis here. This way, you can continuously get your payment with little profit and re-invest in newer projects with your friends company.

Sometimes, company may re-roll the capital for other projects as cash-flow is very critical .... some investors doesn't seem to get anything in return for a very long time while the others currently under it's payroll continue to enjoy the benefit.

If the company goes bust, you may feel sorry for him for loosing everything and may put the idea of re-payment aside. But if a preferential-options were given during your initial capital injection, every-time payment were issued to them, you get something back that would reduce your risk and re-assist them in the future.

Just my 2cents.

than u kena con.
Bumi contractor with kewangan they will received payment before they start.

than he is not class A contractor, just another sub con ....
Bumi Contractor with any gov contract, they can easily can advance payment without requesting it
i have one company supplying Malaysia Army, even now, their advance payment still solid.

Stamped

Although late stamped document may have penalties applied to it, but at least it will be proof that is acceptable in the court.

But normally, we have a lawyer which overlook all transactions. It's normally around RM400 to RM800 per agreement to have them involved, which facilitates preparations, documents, stamping, etc...

It makes your life easier if anything goes wrong.
