That piece of equipment you've been waiting to buy. The experienced project manager you can't quite afford to hire. The larger job you had to pass on because you couldn't float the materials. These aren't cash flow problems — they're AR problems wearing a disguise.
When I work with construction and manufacturing owners, they rarely connect the dots between their aging receivables and the growth they're leaving on the table. But the math is simple: every dollar sitting in a customer's bank account is a dollar you can't deploy.
The real cost of slow collections
Let's say you're running a $5M revenue business with 45-day average collections. That means you've got roughly $625K tied up in receivables at any given time.
Now imagine you tightened that to 30 days. You'd free up about $210K in working capital — not by borrowing, not by giving up equity, but by collecting what you've already earned.
That $210K could be a down payment on equipment that lets you take on bigger jobs. It could be three months of salary for a senior estimator who helps you win more profitable work. It could be the float you need to stock materials for a major project.
Instead, it's subsidizing your customers' cash flow.
How AR problems compound
The damage from loose AR management doesn't stay contained. It spreads.
You start cherry-picking jobs. When cash is tight, you take the work that pays fastest, not the work that pays best. I've seen contractors turn down $800K projects with great margins because they couldn't handle 60-day payment terms — while their receivables report showed $150K over 90 days that nobody was chasing.
You lose negotiating leverage. Suppliers offer better pricing for COD or quick-pay terms. But if your cash is trapped in receivables, you're stuck paying list price or worse. That 2–3% you're giving up on materials adds up fast.
You can't invest in capacity. Growth requires spending money before you earn it — hiring ahead of demand, buying equipment before the big job, building inventory. Poor AR management keeps you perpetually one step behind.
Why it happens
Most of the founders I work with aren't careless. They're just busy running the business, and AR management feels administrative. It gets delegated without clear accountability, or it becomes something everyone assumes someone else is handling.
A few patterns I see repeatedly:
No defined collection process. Invoices go out, and then... hope. No systematic follow-up at 30, 45, 60 days. No escalation path.
Invoicing delays. The work gets done, but the invoice doesn't go out for two weeks because someone's waiting on final numbers or job costing. That's two weeks of free financing for your customer.
Relationship fear. "I don't want to damage the relationship by asking for payment." Meanwhile, your customer is paying their other vendors on time because those vendors actually ask.
No visibility. The owner doesn't see the AR aging report weekly. Problems don't surface until they're severe.
Where to start
Pull your AR aging report right now and calculate your days sales outstanding. Divide your total receivables by your average daily revenue. If that number is higher than your standard payment terms, you've got a collection problem, not a terms problem.
Then pick your three largest past-due accounts and make a call — not an email, a call — this week. Find out what's holding up payment. Sometimes it's a dispute you didn't know about. Sometimes they're just waiting to be asked.
Build from there: weekly AR reviews, systematic follow-up cadences, invoicing within 48 hours of project completion. None of this is complicated, but it requires someone owning it.
If you're not sure where the gaps are, or you need help building a system that actually gets followed, that's exactly the kind of operational finance work we do at Laverton Advisory. Sometimes an outside perspective spots the patterns you're too close to see.
