The hardest money to collect is money you have already earned. The plants left the nursery weeks ago, the customer is happy, and somewhere in the gap between "delivered" and "paid" a chunk of your working capital is quietly sitting still. It doesn’t show up as a loss. It shows up as a nursery that is busy, profitable on paper, and always a little short of cash.
Most growers manage this the hard way — a spreadsheet that’s out of date by Tuesday, a shoebox of invoices, a monthly panic where someone digs through the accounts and starts phoning the worst offenders. It works, roughly, but it depends entirely on a person remembering to do it, and it always finds the problem late: when the debt is 90 days old instead of 30, and when the money is hardest to recover.
The alternative is to make the chase a workflow: a handful of steps that run the same way every time, so being paid on time is the default state of the business rather than a monthly scramble.
