Manufacturing businesses have a cash flow problem that most accountants do not fully appreciate — and that most owners only discover when it is already causing pain.
Your order book is growing. Revenue is up. Margins are holding. On paper the business looks healthy and yet the bank balance is tighter than it should be and you are constantly wondering where the cash is. This is not a sign that something has gone wrong. It is a predictable consequence of how manufacturing businesses work financially.
Why manufacturing eats cash differently
The core issue is timing. Cash goes out long before it comes back in. You buy materials, hold stock, commit labour, build, deliver, invoice and then wait. Thirty days. Sixty days. Sometimes longer. Throughout all of that your cost base runs continuously. When you are growing ths can lead to larger contracts, more capacity, hiring ahead of demand and the gap widens. The faster you grow, the wider it gets.
The four levers that change your position
Debtor days — if your terms are thirty days but collection runs at fifty-five, that gap is funded by your overdraft. Tightening credit control is one of the fastest ways to improve cash without changing anything else.
Stock and WIP — work in progress is cash on your shop floor waiting to be invoiced. Reviewing WIP reporting discipline can release significant cash without external financing.
Supplier terms — securing or extending payment terms with key suppliers even modestly can meaningfully improve your cash cycle. Most long-term suppliers will negotiate.
Milestone billing and deposits — for contracts running over weeks or months, billing at defined stages rather than delivery transforms your cash position. Most customers accept it when built in from the start.
The businesses that manage this well have a thirteen-week cash flow forecast updated weekly. If your monthly accounts do not include a forward-looking cash projection, you are flying partially blind.
