AI Invoicing App Builder for Security Companies
Stop rebuilding the same invoice in a document every week. Tell Mythex how your security company charges and it builds an invoicing app with clients, line items, totals, tax and a paid/unpaid list.
Who it's for
Security companies invoicing from a word processor or a spreadsheet, and chasing payment from memory.
What you can build
- Clients with billing details and payment terms
- Invoices with line items for manned guarding and event security, tax and totals
- A PDF you can download or email to the client
- A paid / unpaid / overdue list with what is due this week
- Quotes that turn into an invoice once accepted
How security companies work
A security company runs round-the-clock rotas across many client sites: static guards at offices and construction sites, mobile patrols, event staff, alarm response and key holding. Every officer's license and site induction must be current, and every shift must be covered even when someone calls in sick at 3 a.m. Contracts are usually billed by the hour per site. Rotas are often rebuilt weekly in spreadsheets and incident reports written on paper, so shift planning and reporting are where software pays off.
What invoicing app for Security Companies has to handle
- Invoices must be built from hours actually worked on each site, not the planned rota.
- Nights, weekends and public holidays usually carry different hourly rates that need applying automatically.
- Alarm callouts and extra patrols should be added as separate charges.
- Clients with many sites expect one monthly invoice broken down by site.
A tip for security companies
Invoice from confirmed shift hours rather than the planned rota. Clients notice when a shift ran short or an officer left early, and an invoice that already reflects that builds more trust than a credit note issued after a complaint.
A prompt to start from
Build an invoicing app for a security company. Keep a list of clients with client name, site and shift. Create invoices with a number, date, due date, line items for manned guarding, event security and alarm response, quantity, rate, tax and total. Generate a printable PDF, mark invoices paid or overdue, and show a dashboard of outstanding money. Add quotes that can be converted into an invoice, and store everything in a database.
Questions
Can invoices apply higher rates on public holidays?
Yes, rates can be set by day type and time, and the invoice applies the right rate to each shift worked.
Can it produce a PDF?
Yes. Ask for a printable invoice and Mythex builds a clean PDF layout with your details, logo and numbering, which you can download or attach to an email.
Does it handle tax?
Say which tax applies and at what rate and it is calculated per line and shown in the total. If you bill in more than one currency, say that too.
Do I need to know how to code?
No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.
Do I have to explain my business every time?
No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.
How much does it cost?
There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
