Tracking Your Money & Keeping Records
Master the core concepts of tracking your money & keeping records tailored specifically for the Manufacturing industry.
💡 Core Concepts & Executive Briefing
Understanding Cash Flow
In manufacturing, cash flow is the heartbeat of the shop. Money comes in when you ship product and collect payment. Money goes out when you buy steel, resin, fasteners, packaging, fuel, and labor. If you keep paying vendors, freight carriers, and payroll faster than cash comes back from customers, the plant can look busy and still be broke. That is how good manufacturers get squeezed.
A factory is not like a service business. You often spend cash weeks or months before you see a dollar. You may buy raw material today, run production next week, ship in two weeks, and get paid in 30, 45, or 60 days. If you do not watch the timing, you can run out of cash while orders are still strong.
The Importance of Basic Records
Good records are not just for the accountant. They tell you what each job, line, and customer is really doing. At a minimum, you need clean records for sales, open purchase orders, raw material buys, labor, scrap, freight, machine repairs, and inventory levels. Without that, you are guessing.
Think of records like the control panel on a press line. If the gauges are wrong, you do not know if the machine is safe to run. In the same way, if your books are messy, you do not know whether your plant is actually making money or just staying busy.
Real-World Scenario
Picture a metal parts shop running a big OEM contract. The schedule is full, the machines are turning, and the team is proud of the output. But the owner forgot that the customer pays 45 days after invoice, while the shop had to buy steel upfront and pay overtime to hit the due date. The job looks like a win on the floor, but the bank account is under pressure. When the owner tracks cash by customer and by job, they see the truth: the contract is profitable on paper, but the payment terms are starving the business.
The Bootstrapper's Ledger
You do not need fancy software to start. A simple weekly ledger works if you keep it current. List cash in from customer payments, then cash out for materials, payroll, utilities, maintenance, freight, rent, insurance, and debt payments. Add a separate line for inventory buys, because cash tied up in raw materials and work-in-process is cash you cannot use elsewhere.
This gives you two numbers that matter:
- Burn rate: how much cash leaves the business each week or month
- Cash runway: how long you can keep operating with the cash you have today
For a manufacturer, this also means watching the cash gap between purchasing raw material and collecting on finished goods. If that gap widens, the business needs more working capital.
Forecasting and Decision Making
Forecasting is how you stay ahead of the plant instead of reacting after the damage is done. If you know a big batch of orders is coming, you can plan for material purchases, overtime, maintenance, and freight before the bills hit. If a customer is likely to delay payment, you can slow inventory buys or push for deposit terms.
This matters when you are deciding whether to add a shift, buy a used CNC machine, hire a scheduler, or take on a new customer with long payment terms. A manufacturer with six months of runway has options. A manufacturer with six weeks of runway has to make hard choices fast.
Conclusion
If you want a stable manufacturing business, you must know where the cash goes, when it comes back, and what is sitting in inventory. Strong records let you see problems early, protect payroll, and make better calls on production, pricing, and growth. Busy does not always mean healthy. Cash tells the real story.
Practical Example
Imagine you run a plastics molding plant. You get a large order, but it requires upfront resin purchases, mold setup time, packaging, and two weeks of production before shipment. By forecasting cash flow, you can decide whether you can cover the material buy, pay operators, and still have enough left for utilities, maintenance, and taxes before the customer pays.
⚠️ The Industry Trap
The trap in manufacturing is thinking the floor is the business. A plant can be loud, busy, and full of work orders while the money side is falling apart. Owners often trust the monthly P&L, but they do not notice that cash is trapped in raw material, WIP, and finished goods sitting in the warehouse.
A common failure looks like this: the shop keeps accepting rush orders, buys extra material to stay ahead, and stretches vendor payables to make payroll. On paper, sales look strong. In reality, the bank balance is getting thinner every week. By the time the owner checks the books, they are already behind on supplier terms and forced to use expensive credit just to keep the lines running.

📊 The Core KPI
Cash Conversion Cycle: Measures how many days cash is tied up from buying materials to getting paid by the customer. Formula: Days Inventory Outstanding + Days Sales Outstanding - Days Payables Outstanding. In manufacturing, a healthy small-to-mid-sized operation often targets 30 to 90 days, depending on product mix and customer terms. Lower is better because it means cash comes back faster.
🛑 The Bottleneck
The bottleneck is usually not the ledger itself. It is the habit of running the plant first and looking at the money later. Many owners know every machine on the floor, but they cannot say how much cash is tied up in raw material, WIP, or slow-paying customers. That delay causes trouble.
A shop may have full trailers of finished goods, but if invoices sit uncollected for 60 days, payroll still has to be met every Friday. The constraint is the owner's lack of a simple weekly cash view, not the accounting system. When cash visibility is weak, decisions on materials, overtime, and new orders become guesses instead of facts.

✅ Action Items
1. Run a weekly cash meeting with your controller, plant manager, and buyer. Review cash on hand, open receivables, vendor payables, payroll due, and planned material purchases.
2. Build a simple 13-week cash forecast. Include expected customer collections, steel/resin buys, freight, overtime, repairs, rent, and loan payments.
3. Separate inventory into raw material, WIP, and finished goods. Track how much cash sits in each bucket so you know where money is trapped.
4. Review your biggest customers' payment terms. Push for deposits, progress billing, or shorter terms on long-run jobs when possible.
5. Use your ERP aging reports to spot slow-paying accounts and old inventory. Chase collections early and reduce dead stock before it eats more cash.
6. Put aside cash for taxes, insurance renewals, and maintenance shutdowns so those bills do not crush the month they hit.
