When can i apply for advance payment - Advance Computers & Internet

You have to tell the lender how to apply the extra. If you want it to apply to the next payment, enclose a note with your payment.

A business cash advance is based totally on the purchase of your future credit card sales. Payments pursuant to the purchase arrangements among businesses are made by an automatic deduction of a percentage of your future credit card sales. An authorized processor manages those payments. You do not have to make conventional loan payments and be concerned with cash flow.

you'd have to go back to centrelink and sign in and contact them and tell them you want to change to whole payment

It sounds like you mean a Centrelink advance. You can only apply for one every 12 months. Check the date your last one was approved and add a year - that's the next date you can apply for a new advance. This date can be checked and advances applied for using the Centrelink online service.
Also, there are other loans and payments available depending on your needs. For example, if you need equipment to start a new job (like tools, safety gear, etc) Centrelink may be able to advance that money in addition to a normal advance.

Maybe you will find the solution in the site Toyswill.

You can request a payment deferral where they take your next payment and put it at the end of the loan thus allowing you the time to put the money up for the next payment and keeping you from being late. If all else failss i suggest that you look into refinancing with another bank or loan company at a lower apr rate.

You would assign the part payment to the creditor of the PO and not the PO itself?

That way if your PO is not receipted - Your payment has still been made and registered.
