How are you handling document chaos at the start of a new deal?

Genuine question for anyone actively evaluating. When a seller sends over the folder (tax returns, QuickBooks exports, bank statements, maybe some handwritten notes), what does your intake process actually look like? I have talked to a lot of people who are doing this entirely manually. Building the SDE reconstruction from scratch in Excel, normalizing formatting across multiple file types, manually hunting for the owner compensation number and cross-checking it against anything they can find. It works. But it takes hours. And it happens before the real analysis even starts. Curious whether people have found better ways to run this, or whether the manual grind is just accepted as part of the process at this stage.
