Statements that do the chasing for you
GrowSheet turns fulfilled orders into invoices and month-end into per-buyer statements that read like a bank statement — paid on your own rails, never processed by us.
How this calculator works
Each invoice's days past due is its age minus your terms (net-30 → 30 days). Balances land in current, 1–30, 31–60, 61–90, or 90+ past due. It's the standard A/R aging every accountant runs — see the net-30 guide for how to use it.
What net 30 actually means
Net 30 means the full invoice amount is due 30 calendar days after the invoice date — not 30 business days, and not 30 days after delivery unless your terms say so. The variants work the same way: net 15 is faster money, net 60 is a customer asking you to be their bank for two months. 2/10 net 30 adds an early-payment deal — 2% off if paid within 10 days, full amount at 30. For a grower, that discount is usually worth offering: 2% is cheap next to chasing a 60-day-late wholesale account.
An invoice is late the day after the due date. What keeps net terms from quietly becoming "net whenever" is aging them — which is what the tool above does: sort every open invoice into current, 1–30, 31–60, 61–90, and 90+ days past due, and call the right column first.
