How it works
From first call to live system
in days, not months.
01
15-minute demo
We share a screen and show you the program running with real data from your sector. No slides, no sales script.
02
We set it up for you
You don’t configure anything. We build your system, add your menu, products or services, and test it before you touch it.
03
You go live
Your team gets a short walkthrough. You start using it. We stay reachable — not a ticket system, a real person.
04
Month two onwards
Month-to-month. If it’s working for you, you keep it. If not, you leave with 30 days’ notice and your data.
See your sector’s software running live.
15 minutes, screen shared, your real questions. No commitment required.
Why M&M Sys
What makes it different
from the big platforms.
Built for one trade, not for all of them
Generic software makes you adapt your business to the program. Each M&M Sys product is built around how that specific sector actually works — its vocabulary, its workflow, its daily problems.
No commission on your revenue
Flat monthly fee. We don’t take a cut of your bookings, your sales or your transactions. What you earn is yours.
You talk to the person who built it
No call centre, no support ticket that takes three days. When something needs fixing, you reach the team directly.
Price that fits an independent business
From £29/month. Set up from £150. Designed for businesses that run on tight margins, not for enterprise clients with IT budgets.

Questions
The things people ask
before they book a demo.
Do I have to sign a 12-month contract?
No. There is a minimum of one month, which covers the setup cost. After that it is month to month — cancel with 30 days’ notice, no questions asked. What is included in the setup fee?
We configure the software for your business: your menu, products or services, your users and your settings. You do not configure anything yourself. Can I use it on my existing hardware?
In most cases yes. We check your current hardware during the demo call before you commit to anything, so there are no surprises after you pay. What happens to my data if I cancel?
Your data belongs to you. Before your account closes we export everything in a standard format so you can take it wherever you go. Do you only work in London?
We are based in London and most of our clients are here, but the software runs online so geography is not a barrier if you are elsewhere in the UK. How long does setup take?
Typically a few days from payment to going live, depending on how much information you provide (menus, product lists, team details).
