> Even a plumber who types up offers and invoices on a computer is subject to all of this mess.

Yeah and that plumber has 1000s of customer names, addresses, phone numbers, mail addresses, in Europe maybe even SEPA Direct Debit data.

Not funny if that kind of stuff leaks, especially not if you're, say, a person with a public register block due to domestic violence or whatever (basically, one step before witness protection that gives you a whole new identity).

Thousands of customers? Your numbers are out of touch with reality.

In Germany you have to keep your records for 8 years as a commercial entity, and 8 years is a lot of customers you deal with, if you work with private customers.

If your primary focus as an electrician, plumber or other tradesperson is SME or industry, of course, then there is far less customers.


No plumber I know is able to deal with more than a thousand different clients in eight years. This is so absolutely unrealistic it's laughable.

Repeat customers, certainly, there's only so many of them you can have. I'm talking about small shops with 5-10 people heading out to service calls, and a lot of these is "throwaway" customers that need a water faucet changed or whatnot.

At least here in Germany, in most rental contracts the responsibilities are split between landlord and renter, with the landlord being responsible for the heating, the water mains and the large fusebox, but the renter has to deal with everything under the scope of "Kleinreparatur". Exchanging faucets and siphons, wall sockets, installing laundry machines and other appliances, installing lamps, that kind of stuff many people (like me) can DIY but other people (like a lot of my friends) can't or don't want to, and they call in the professionals for an hour or two. And these guys have like 4-6 service calls a day.


I know all of that. Still, I can't make the overall numbers for Germany work out in a way that gets to a customer base of any scale for plumbers.

250 work days in a year assuming no weekends and no other vacation (because it makes a round number). 2000 work days in 8 years. You can't see how a plumber might see more than 0.5 customers per day?
