I work with tons of new investors as an agent and when we are putting together a proforma, it's pretty easy to estimate the cost of most capex items and approximately when they'll hit.

The rest are a couple hundred bucks per invoice or ~$1k (labor) I don't have the invoices to review, however if each invoice is for a SEPARATE job (and itemized/below $2500), then yes generally you can expense under the de minimus safe harbor.

For each line item, generate your best estimate based on your own knowledge and basic research.

I would need to check the books and then propose a price.I get the “AI will replace bookkeepers/accountants” argument, but I think it misses the core reality of what accounting actually is in practice: It is constantly a gray and depends on context that rarely lives inside the transaction itself.A bank feed line item is just a line item.
