Dear Mayy,
May I share my opinion and doubt, for IEL they just provided delivery service and they never have done billing process for us.
In the same time, When Ops dept. prepares to deliver goods to hospital they usual put invoice inside to bill them
for Account dept & hospital do their payment process as our practice now. For penalty charge it should be for late delivery not for late billing.
For this case, is it possible if we deliver goods as usual and billing to P’Wan other day?
Maybe I ask a favor from Angie to help due to she go to this hospital quit often.
Please advice.
