Tools built for one buyer
Some work will never fit a shelf tool. A calculation that belongs to one company and nobody else. A workbook that grew for four years until the person who built it left and nobody trusts the totals. A monthly pack that has to land on the fifth, every month, in the same shape. Those get built to order.

BEFORE YOU SEND ANYTHING
Your file stays yours
A workbook you send is used for the job you asked for and for nothing else. It is never shared, never used as an example, and never kept as a sample. My copies are deleted as soon as the work is delivered.
If you need a non-disclosure agreement signed before you send anything, say so and it gets signed. It costs nothing and it is a normal way to start.
One thing I do not control, and would rather say than hide: the file travels through Upwork, so Upwork keeps its own copy under its own retention policy. What I can promise is my copy, and that one goes.
Send the file, not a brief
