Sigh....
We bought a small run down business, husband and wife with one employee two days a week. The till was a Tupperware box in the filing cabinet.
We invested another heap of money, revamping the shop, counter, putting in a top of the range til, buying small tools and plant.
As the money came in every penny was banked and spent in the business. We doubled the turnover in the first year.
We survived on an income from another source.
In comes customs and excise surprise visit. They went through everything which we'd computerized instead of using shoe boxes and Tupperware till. Because we'd doubled the turnover, taken no drawings and employing two more staff, one an apprentice.
I panicked and phoned the accountant explaining their searching questions. His response.
"Tell them to fuck off"
My books were absolutely straight, the accountant had taught me how to do them and checked them every quarter.
I can only surmise the previous owner had purloined any cash sales which we didn't.
Customs after two days found £4 I had made a mistake with.
