Invoicing software for security companies in Singapore

Most agencies bill the same recurring contract value to the same building managers and facility clients each month, but the invoice still gets rebuilt by hand in a spreadsheet. Add a few site changes, one extra relief guard and a public holiday shift and someone is retyping line items at 9pm on the last day of the month. It is slow, and one mistyped rate can quietly undercharge a client for a whole year.

Ops keeps the roster and deployment sheet. Finance keeps the invoice file. When a client disputes a shift or asks why the invoice went up, nobody can pull one clean record showing which site, which dates and which rate were billed. Chasing that answer across WhatsApp groups, roster printouts and old PDFs costs hours and makes collection conversations awkward.

A single job can include guarding services, a CCTV supply and install, and a maintenance retainer. Once your taxable turnover crosses the S$1,000,000 threshold and you are GST-registered, every one of those lines has to be captured correctly so your GST F5 return actually reconciles to your sales records. Getting there from spreadsheets means recalculating output tax by hand every quarter.

Cameras, DVRs, alarm panels, cabling, uniforms and radios sit in a store room with no real count, so you reorder items you already have and lose track of what went out on which install. Meanwhile corporate clients pay on 30 to 60 day terms while payroll and CPF go out every month, and without a live view of who owes what, cash gets tight without warning.

Set up each client site once with its contracted monthly value, guard positions and rates, then let Tallium AI generate the invoice on the same day every month. You review, adjust for extra deployments or overtime lines, and send. Month-end billing becomes a check-and-approve task instead of a rebuild, and rate changes are updated once on the contract rather than retyped on every invoice.

Because invoicing, accounting and reporting share one database, every invoice line stays linked to the site, the period and the person who raised it. When a client queries a charge, you open the invoice and see the full history including edits, sends and part payments. Unlimited users means your ops coordinators can raise and check billing detail directly, with roles controlling who can approve or edit.

Tag each line with the right GST treatment when you raise the invoice, and Tallium AI keeps output and input tax running all quarter so your GST F5 figures are ready when the filing window opens. Tax invoices carry your GST registration number and the required details, and the structure supports moving to InvoiceNow (Peppol) e-invoicing with your corporate and government-linked clients. Please confirm current rules and rates with IRAS or a local tax professional before you file.

Track cameras, panels, cabling and consumables with live quantities, so what leaves for an install is deducted and reorder points warn you before a job stalls. AI receipt scanning captures supplier bills and categorises them without manual entry, and your aged receivables view shows exactly which clients are past terms so collection calls target the right accounts first.
