This shall not prevent the making of a contract for a term exceeding one (1) year, nor require the city to pay during a fiscal year any amount larger than is due during that year under the terms of the contract.

When any claim shall not be collectible by other methods, he shall report the same to the City Attorney for collection.
G. 
Keep all general accounts of the city, and of the respective departments, offices, boards, commissions and agencies thereof and keep separate accounts for the items of appropriation contained in the city budget showing the amount of the appropriation, the amount paid therefrom, the unpaid obligations against it and the unencumbered balance.

No claim against the city, except for a fixed salary, or for the principal of or interest on indebtedness, shall be paid unless an itemized voucher therefor, certified by or on behalf of the claimant, in such form as the Commissioner of Finance shall prescribe, shall have been presented to the Department of Finance. Notwithstanding any other provisions of this Charter, no claim other than a claim for a sum certain due by contract for goods delivered or services rendered shall be paid unless and until such claim shall also have been presented to and approved by the Common Council; or such claim shall have been ordered paid by a court of law.
I.
