Invoicing and accounting software for security agencies in India

Every month starts the same way: pull the duty register, count posted guards per site, add overtime, subtract absent days, then retype it all into an invoice. One agency with 20 client sites can lose a full week to this, and a single copy-paste error means a client short-pays or a credit note has to be raised.

Security personnel supply has its own reverse-charge treatment depending on whether the supplier is a body corporate and who the recipient is. Getting the charge, the invoice wording or the GSTIN wrong on a client bill leads to disputes, blocked input credit for your client, and mismatches when GSTR-1 data flows into their GSTR-2B.

Corporate and facility-management clients pay slowly, but guards must be paid on time. Without a live receivables view by client and by site, you find out about a three-month-old unpaid bill only when cash runs short, and by then the paperwork trail for a follow-up is cold.

Wages, ESIC and PF contributions, uniforms, torches, radios, training and supervisor travel all get lumped into one pile of expenses. So a site billed at a thin margin quietly eats the profit from three good ones, and you only see it at year end when your CA closes the books.

Set up each client with their sites, guard categories and monthly rates once. Tallium AI generates the next month's invoice from that template — you only adjust the actual deployment, overtime hours and any deductions. Invoices carry your GSTIN, the client's GSTIN, HSN/SAC details, place of supply and the correct tax split, then go out by email straight from the app.

Tax is applied at invoice level and every sale, purchase and expense lands in your books immediately, so period-end reports line up with what you actually issued. You can pull the summaries needed for GSTR-1 and GSTR-3B instead of reconstructing them from spreadsheets, and structure invoices to suit e-invoicing through the Invoice Registration Portal (IRP) once you cross the applicable turnover limit. Confirm current rules with CBIC or a local tax professional.

Every invoice shows its ageing bucket by client and site, so you can see the ₹4 lakh sitting at 90 days before it becomes a write-off. Send polite payment reminders from the app, record part payments against the right bill, and hand your collections team a shared, always-current list rather than a stale printout.

Tag wages, statutory costs, uniforms and equipment against the site they belong to, and scan supplier bills with your phone so nothing is lost in a drawer. AI insights flag which contracts are drifting — rising overtime, shrinking margin, slower payment — while there is still time to renegotiate the rate at renewal.
