An Owner's Guide to Cash Flow Management for Manufacturers

Cash flow management for a manufacturer is mostly a habit. The owner looks at the same few numbers every week, makes a handful of decisions, and doesn't get surprised by payroll.

We already have plenty of posts on forecasting methods and cash strategies. This one is narrower. It's about the owner's part: the weekly routine, the decisions that move cash, and how to tell whether the business can afford what you're about to say yes to.

Why does cash need the owner's attention every week?

Because the big cash decisions in a manufacturing company are owner decisions. Taking a large order, buying material ahead of a price increase, adding a shift, buying a machine, taking a distribution. Your team can track cash. Only you can decide those.

The P&L won't warn you in time. It shows profit, not timing. You can have a profitable quarter and still be tight on the 15th, because you paid for material in March and the customer pays in June. Our post on cash flow vs. profit covers that gap in more detail.

I think 30 minutes a week is enough for most owners. The key is doing it every week, including the good weeks.

What are the three types of cash flow?

Your cash flow statement splits cash into three buckets. It helps to know which bucket a decision falls in.

1. Operating cash flow

This is cash from running the plant: customer collections in, and material, payroll, rent, utilities and other operating costs out. Over time, this should be positive and should roughly track your earnings. If it doesn't, receivables or inventory are absorbing the difference.

2. Investing cash flow

This is cash spent on long-term assets, mainly equipment, tooling, buildings and improvements. In manufacturing this bucket can be large and lumpy. One machine purchase can wipe out a quarter of operating cash if you pay for it out of the bank account.

3. Financing cash flow

This is cash from lenders and owners: loan proceeds, loan payments, line of credit draws and repayments, and owner distributions. A healthy pattern is borrowing long-term money for long-term assets and using the line for short-term swings.

One rule I'd hold to: don't fund investing cash flow out of operating cash unless you have plenty to spare. Machines should usually be financed over something close to their useful life.

What does the owner's weekly cash routine look like?

Pick a day and time and keep it. Monday morning works for many shops because payroll and vendor runs often happen later in the week. The owner, the controller or bookkeeper, and sometimes the plant manager attend.

Here's what should be on one page.

1. Cash in the bank today, and available on the line of credit.
2. Expected collections for the next two weeks, by customer for the big ones.
3. Payroll and payroll taxes due in the next two weeks.
4. Large payables due, especially material and anything past due.
5. Planned purchases over a set amount, like a large material buy or a capital item.
6. Receivables past terms, with who is calling each one.
7. The ending cash balance in your 13-week cash flow, and how it changed from last week.

The last item is the one that matters most. If the low point in the forecast moved by $200,000 since last week, you need to know why. Building the forecast itself is covered in our guide to building your cash flow forecast.

Which decisions should come out of the meeting?

A cash meeting that ends without a decision is just a report. Each week, there are usually three to five calls to make.

Which bills to pay this week and which can wait until terms. Which customers need a call from the owner rather than accounting. Whether to approve a large purchase now or next week. Whether to draw on the line or pay it down.

Write the decisions down. Next week, start by checking whether they happened.

Can you afford to take that big order?

This is a decision owners often get wrong on cash. A large order is good news. It also needs cash before it pays.

Here's an illustrative example. A customer offers a $600,000 order. Material is 40% of price, or $240,000, bought at the start and paid on net 30. Direct labor is 20%, or $120,000, paid over six weeks of production. The order ships in week 8, and the customer pays net 45.

Week	Cash out	Cash in	Cumulative
1 to 4	$80,000 labor	$0	-$80,000
5	$240,000 material, $20,000 labor	$0	-$340,000
6	$20,000 labor	$0	-$360,000
7 to 14	$0	$0	-$360,000
About 15	$0	$600,000	+$240,000

The order earns $240,000 of contribution before overhead. But you need $360,000 of cash or line availability for about ten weeks to get there. If you don't have it, you have three options: ask for a deposit or progress billing, negotiate longer material terms, or arrange more borrowing before you accept.

I'd rather have that conversation with the customer and the bank before signing than after.

How much cash should a manufacturer keep on hand?

There's no single right number. It depends on how lumpy your sales are, how reliable your customers pay, and how much line of credit you have.

One way to set a floor is two payrolls plus one month of fixed costs. Illustrative: payroll of $180,000 every two weeks and fixed costs of $150,000 a month gives a floor of $510,000 ($360,000 plus $150,000). Available line of credit can count toward it, as long as you're comfortable with your covenants.

The floor gives the weekly meeting a simple test. If the 13-week forecast dips below it, something needs to change now: a collection push, a delayed purchase, or a call to the bank.

How should owners plan distributions and taxes?

If your company is an S corporation or partnership, profits flow to your personal return, and you'll often take distributions to pay the tax. Those distributions are real cash leaving the business, usually around the quarterly estimated tax dates.

Put them in the 13-week forecast like any other bill. A common surprise is a strong year that ends with a big tax distribution in April and a thin cash balance in May. Your CPA can estimate the amounts, and we put them on the calendar. This is general information, not tax advice; work with your CPA on your situation.

Which cash metrics should the owner watch monthly?

Weekly is for cash and decisions. Monthly is for the trends behind them. Three numbers cover most of it:

• DSO, days sales outstanding: how fast customers pay.
• Days inventory outstanding: how long material and finished goods sit.
• DPO, days payables outstanding: how long you take to pay vendors.

Together they make up the cash conversion cycle: DSO plus inventory days minus DPO. Say DSO is 50, inventory days are 70 and DPO is 35. Your cycle is 85 days.

If your annual cost of goods sold is $9,125,000, that's $25,000 a day. Cutting the cycle by ten days frees about $250,000 (illustrative). That's usually easier than finding $250,000 of new profit.

Where do owners usually lose cash without noticing?

A few patterns come up again and again.

Paying vendors early "because we have the cash this week", then drawing on the line two weeks later. Buying material in bulk for a discount that's smaller than the cost of carrying it. Letting a big customer stretch from 45 days to 75 without a conversation. Paying for equipment with cash and then running tight on payroll.

None of these is a disaster alone. Each one is a decision someone made without the cash picture in front of them. The weekly meeting fixes that.

How should cash flow tie to your growth plans?

Every growth plan has a cash cost. A new product line needs inventory. A new customer needs receivables. A second shift needs payroll before it needs a sale.

Before you commit, add the plan to the forecast and see where the low point lands. If it drops below your floor, plan the funding now, whether that's a bigger line, equipment financing or a slower ramp. Our post on why growth can break your cash flow goes deeper on this, and ways manufacturers raise capital covers the funding side.

When should you get outside help?

If you don't have someone who can build and update the 13-week forecast each week, that's the first gap to fill. It doesn't need a full-time hire.

We run this routine for owners as part of our cash flow management work, and tie it to the monthly close through our outsourced controller service. Happy to walk through how it would work for your shop.

Frequently Asked Questions

How much time should an owner spend on cash flow each week?

About 30 minutes, if the forecast is prepared ahead of time. The time goes to decisions, not to building the numbers.

What is the most important number in the weekly cash meeting?

The low point in the 13-week forecast and how it changed since last week. That tells you whether you have a problem coming and how fast it's moving.

Should I use cash or a loan to buy equipment?

Usually financing, matched to the machine's useful life. Paying cash can leave operations short, especially if a large order or slow customer comes along.

How do I know if I can afford a large order?

Map when you pay for material and labor against when the customer pays. The peak cash needed in between is what you must have available before you say yes.

What is a good cash conversion cycle for a manufacturer?

It depends on your industry and customer terms. What matters most is the trend: a shorter cycle each year means less cash tied up in the business.
