Security guard company Q&A
How do I invoice monthly guard hours?
Short answer
- At month-end, the system totals confirmed guard hours from each site's shift roster.
- It automatically applies the site's contract rate — confirmed hourly or a fixed monthly package.
- It generates the invoice for each client, with a detailed report per post and hour.
- An online payment link is attached, for fast card payment.
- The payment reconciles automatically against the site, with no manual re-entry.
What the law says (brief)
- Law 227/2015 on the Fiscal Code — the rules for issuing and the mandatory content of an invoice for services rendered.
- Law 333/2003 on the protection of objectives — the billed rate must match the services actually delivered under the contract and security plan.
Practical examples
- Example: a site has 2 contracted posts at an hourly rate. At month-end, the system totals 720 confirmed hours from the shift roster (not estimated hours) and automatically generates the invoice, with a detailed report per post and day, ready to send to the client.
Common mistakes
- Billing is based on the planned roster, not actually confirmed shifts — discrepancies only surface at reconciliation.
- The rate is recalculated manually every month, with a risk of error applying contract terms.
- There's no payment link on the invoice, and collection depends on manual follow-up.
