AI Invoicing App Builder for Health and Safety Consultancies

An invoicing tool shaped like your health and safety consultancy: your services, your tax rate, your terms. Describe it once, then issue invoices from a page instead of a template file.

Who it's for

Owners of health and safety consultancies who want invoices numbered, stored and searchable without paying per month for accounting software.

What you can build

  • Clients with billing details and payment terms
  • Invoices with line items for risk assessments and fire risk assessments, 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 health and safety consultancies work

A health and safety consultancy lives on recurring work: annual risk assessment reviews, fire risk assessments that must be revisited when a building changes, site audits and toolbox training. Clients are usually small employers, landlords and contractors who call when an insurer, a tender or an inspector asks for paperwork. Consultants spend days on site with a tablet or clipboard, then evenings writing reports in a word processor. Software helps most by tracking review dates per site and turning site notes into a finished report faster.

What invoicing app for Health and Safety Consultancies has to handle

  • Invoices should reference the site and the assessment delivered, because clients with many premises allocate costs per building.
  • Retainer billing for clients on an annual support agreement has to sit alongside one-off assessment fees.
  • Mileage or travel charges can be added to site visits where your terms allow it.
  • Purchase order numbers must be captured on each invoice, as larger clients will not pay without one.

A tip for health and safety consultancies

Send the invoice with the report, not a week later. The client's attention is on the document the day it arrives, and a matching invoice with the purchase order number on it gets approved while the job is fresh. Delayed invoices for safety work tend to sit unpaid.

A prompt to start from

Build an invoicing app for a health and safety consultancy. Keep a list of clients with client name, site and assessment type. Create invoices with a number, date, due date, line items for risk assessments, fire risk assessments and site audits, 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 we bill a retained client monthly and still invoice extra site visits?

Yes. You can set up a recurring retainer invoice and add separate line items or invoices for additional visits or training. Card or bank payments would run through a payment provider you connect with your own account.

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.
