The board is the unit of everything. One board is clear, and a question spanning twelve of them — what is late, who is overloaded, which client costs most to serve — has no home, because monday answers per board.
Imported boards are tables. Group, filter and total across all of them at once, and save the answer as a report rather than rebuilding it monthly.
Columns are per board, so the same idea is spelled three ways across three boards and no rollup can span them. Standardising means editing every board and hoping nobody adds a fourth.
Add the field once, to your own table, and every row in it has that field. Nothing about it depends on which board the work started life on.
The work is not attached to the thing it is for. A board of installs knows nothing about the contract, the invoice or the equipment, so the cross-reference happens in somebody's head or not at all.
Link imported items to your customer, deal or asset records, and the operational story and the commercial one finally sit in the same place.
Anything captured outside monday has to be retyped into it, so it arrives late or never. A form submission becomes an item when somebody gets round to it.
An automation files the item as part of the thing that already happened, so the board stays current without anybody copying between tabs.
