A Commercial Client Pays Slow but Orders a Lot: Decision Tree

Why this matters

The whale account feels like a win: steady orders, a big name on the books, your crew always busy. Then you notice payroll is tight even though the backlog is full, because that same account pays on its own slow clock while your labor and material bills do not wait. A large customer that pays slowly is a loan you are making them, secured by nothing. This tree is how you decide whether to feed it, fence it, or fire it, before the loan gets bigger than you can carry.

Start here: measure slow and measure concentrated

Two numbers decide everything. Pull them before you make a call.

• Actual days-to-pay, not the agreed terms. Terms say net 30; behavior might say net 55. Measure the behavior.
• Concentration: what share of your revenue, and of your open receivables, is this one account. If losing them would threaten the company, you are already captive, and every decision below changes.

Write both down. You are managing facts now, not a feeling that you are busy.

Is the work still profitable after the carrying cost?

Money you front is money you cannot deploy. When an account pays late, the cost of carrying that receivable comes straight out of the job's margin.

• If the margin is healthy and you have reserves or a credit line to float the gap, the volume can be worth the wait. Continue.
• If the margin is thin and they pay slow, the volume is a trap. You are working harder to lend money at a loss. Tightening terms is not optional; it is the only way the account makes sense.

A thin-margin job that pays in a season is worse than a fatter job that pays on completion, even if the slow one is bigger.

Is the slow pay fixable or structural?

Not all slow pay is the same. Diagnose the cause before you escalate.

Fixable friction is your fault to fix. A structural slow-payer is using your cash on purpose, and no amount of polite reminding changes that.

The options ladder, least to most drastic

Work down only as far as you need to.

1. Fix the invoicing friction. Right purchase-order number, right billing contact, right format, submitted on their cycle. Sometimes "slow" is self-inflicted, and the clock never really started.
2. Change the structure on new work. Progress billing or milestone billing so you are never fully exposed; deposits on new orders; shorter terms going forward.
3. Price the delay. A finance charge on past-due balances where your state allows it, or a prompt-pay discount that makes paying fast the customer's own idea.
4. Cap the exposure. Set a credit limit for the account. New orders wait in line until older invoices clear. This is the single most effective brake on a growing balance.
5. Diversify, then decide. Use the volume as a reference to win accounts that pay faster, so this one stops being able to hold you hostage.
6. Convert to prepay or let them go. If it is a structural slow-payer eating cash you cannot spare, and you can survive the loss, put them on prepay or walk. A liability with a logo is still a liability.

The rule to keep

Never let one account carry more exposure than you can afford to lose. Volume that ties up cash you need this week is not growth. It is risk wearing a big name. Manage the receivable as deliberately as you chased the sale.

Recap

1. Measure real days-to-pay and how concentrated the account is.
2. Confirm the work is still profitable after the cost of carrying the receivable.
3. Diagnose fixable friction versus structural slow pay.
4. Fix your process, then tighten structure, then price the delay, then cap exposure.
5. Diversify so you can afford to convert them to prepay or fire them.
