Unlike Excel, there's no need to build complicated templates or worry about formulas. Everything is ready to go—just input your details, and the app handles the rest. It’s faster, simpler, and specifically designed for tradespeople. With OptimusInvoice, you can save time and avoid mistakes.
Optimus Invoice is the desktop app built for trades and service pros — helping you take control of quoting and invoicing without the admin overload.
Optimus Invoice was shaped by electricians, plumbers, and builders who told us what slows them down. It’s fast, intuitive, and helps avoid missed quotes and late payments — because paperwork shouldn’t cost you work.

Hello, I'm Ann Marie, the founder of AMG Optimus Ltd. With a deep passion for empowering businesses and individuals, I help businesses work smarter—not harder—by streamlining processes through lean and digital solutions.
With over 10 years of experience and a deep focus on root cause analysis, I’m passionate about eliminating the everyday inefficiencies that hold teams back. My latest project, Optimus Invoice, was born out of a real pain point shared by tradespeople: invoicing and quoting shouldn’t be a weekly battle.
At AMG Optimus, we partner with businesses ready to ditch complexity and embrace practical tools that improve service, reduce waste, and drive real results. Whether you're seeking strategic advice or hands-on help, I bridge the gap between vision and execution—making improvement achievable and customer-focused.
With a degree in Business Operations, I ventured into the professional world, where I honed my strategic thinking and leadership skills. My entrepreneurial spirit led me to establish AMG Optimus Ltd.
