How a Security Agency Closes the Month, from Muster to Invoice and Wages

The close starts with one question: how many duties did each guard stand at each post? Registers, supervisor photos and WhatsApp messages each hold part of the answer. Pull them into one muster per site, guard by guard and shift by shift.

Once the muster is agreed, lock it. Changes after that point carry a note and a name. Billing and wages both read from this count, so it must not move quietly.

Relievers move between sites, so their duties go missing easily. Each reliever duty belongs under the post it covered, not under the guard’s home site. Otherwise one post looks short and another looks over strength.

Note every shift that stayed empty, and for how long. The contract may set a deduction for an unmanned shift. It is better to record it yourself, with the time and the post, than to hear about it first from the client’s admin team weeks later.

The invoice sets duties delivered against duties contracted, post by post. Add the agreed service charge and any deduction the contract allows. Keep the attendance behind every line ready to open.

Client queries tend to arrive weeks later. A post-wise bill with photos and times behind it answers them. A lump-sum bill does not.

The wage sheet starts from duties per guard and adds overtime, night allowance and other earnings. Advances, uniform recovery, PF and ESI come off on rules your accountant has set. If invoice duties and wage duties differ, something slipped.

Agree the deduction rules with your accountant before the first close, not during it. EPFO and ESIC publish their own requirements on their portals. Your accountant reads those and files the returns.

File the month’s night check visits and incidents by site. List guard papers and training dates falling due next month. Mark uniform issued to guards who left for recovery.

Then carry open questions forward in writing. A disputed shift, an unpaid invoice or a pending advance should not live in one person’s memory. Next month’s close then starts clean.
