How to show recurring expenses.?

We have few recurring expenses like rent, payroll processing, accounting, HR solutions, building maintenance, housekeeping and so on. The amount are more or less the same every month. Few months, there may be few changes. These invoices come in the 1st week of the next month. i.e Invoice for Jan month expense is dated on 7th Feb. How to account these effectively.? I ignore the Invoice date completely and account it in the respective months. If this is done, then I need to pay TDS by 7th of next month.? As I am not from commerce bg, I am not getting clarity on my own. Pls guide.
