inventory and payables not balance

[meisam]

hello!!!

I just found out that the amount of my accounts payable in trial balance and balance sheet are equal, but not the same with the amount in supplier balance at a period end.

example is this:
balance sheet amount - 500,000
trial balance amount - 500,000
Supplier balance at period end - 590,000


I also found out that amount of my inventory/stock in trial balance and balance sheet are equal, but not the same with the amount in inventory valuation report.

example is this:
balance sheet amount - 500,000
trial balance amount - 500,000
Inventory valuation report - 590,000

The figures i gave were not the actual...
Will you please help me solve this one..

thank you in advance...
