The manufacturing cash cycle — pay for raw materials, produce, wait for finished goods, dispatch, wait for payment — can span 60–120 days. Managing this cycle is the most important financial discipline for SMB factory owners, yet most manage it reactively rather than proactively.

The Profitable Factory Running Out of Cash#
A Cheshire industrial gasket manufacturer was profitable on paper — gross margin 34%, EBITDA 11% for the year. Yet in March and again in September, the managing director was calling their bank to extend their overdraft because the factory account was running low. The business was growing: new customers, more orders, higher revenue. But the growth was consuming cash faster than it was generating it. The root cause: raw material suppliers required payment in 30 days, production lead time averaged 18 days, and customer payment terms were net 60 days from dispatch. The total cash conversion cycle was 30 + 18 + 60 = 108 days — meaning £1 paid for raw materials today would not return as £1.34 of customer receipts for 108 days. As the business grew, it needed more raw materials, which required more cash upfront, which arrived back more slowly than the business was spending. Profitable growth was causing a cash crisis.
Understanding Your Cash Conversion Cycle#
The cash conversion cycle (CCC) in manufacturing has three components. Days Inventory Outstanding (DIO): how long materials sit as inventory before they are converted to a sale — includes raw materials storage time, production time, and finished goods holding time. Typically 30–90 days in SMB manufacturing. Days Sales Outstanding (DSO): how long it takes to collect payment after a sale is made — your customer payment terms plus any delays in actual payment. Typically 30–90 days in B2B manufacturing. Days Payable Outstanding (DPO): how long you take to pay your suppliers — your supplier payment terms. Typically 30–60 days. CCC = DIO + DSO − DPO. A factory with DIO of 45 days, DSO of 60 days, and DPO of 30 days has a CCC of 75 days. Every 75 days of revenue requires the factory to have funded 75 days of costs upfront. Understanding your CCC is the foundation for managing it.
Reducing DIO: Lean Inventory and Faster Production#
Days Inventory Outstanding is reduced by shortening the time materials spend at each stage before becoming sales revenue. Reducing raw material holding time requires better reorder point management (holding safety stock but not excessive buffer stock) and faster supplier lead times. Reducing production lead time requires lean production improvements — reducing WIP between operations, improving scheduling efficiency, eliminating production delays from materials shortages or machine downtime. Reducing finished goods holding time requires better order management (producing closer to when the customer needs delivery) and faster dispatch processes. Each day you remove from DIO reduces the cash requirement of your production cycle by one day's worth of costs — which for a factory spending £50,000 per month in production costs is £1,667 per day. Reducing DIO by 10 days releases £16,670 of working capital.
Reducing DSO: Customer Payment Terms and Credit Control#
Days Sales Outstanding is managed through payment term negotiation and credit control discipline. If your standard terms are net 60 days, consider whether all customers genuinely need 60 days or whether net 30 is achievable with most — particularly newer or smaller accounts. Early payment discounts (2% for payment within 10 days) can accelerate cash receipt from customers who have cash available but default to using full payment terms. Invoice financing — selling your receivables to a finance provider at a discount — effectively converts DSO to near-zero at a cost of 1–3% of invoice value, which is often cheaper than the cost of an overdraft covering the same gap. Most importantly: send invoices immediately on dispatch, not days later. An invoice sent three days after dispatch adds three days to your DSO for no commercial reason.
Increasing DPO: Supplier Payment Term Negotiation#
Every additional day of supplier credit reduces your net cash conversion cycle. If you are currently paying suppliers in 30 days, negotiating to 45 days adds 15 days of free supplier financing to your working capital. This requires supplier willingness — larger suppliers are more likely to grant extended terms; small specialist suppliers may not be able to. Offering certainty (committing to consistent payment on the agreed date, rather than erratic payment) is often more important to suppliers than payment speed per se. If you have a good payment history, use it as leverage: "We have paid you on time consistently for three years; we'd like to discuss extending terms to 45 days as our business grows." Dynamic discounting platforms allow you to pay early when you have surplus cash in exchange for a small discount — which can be mutually beneficial.
How AskBiz and Xero Provide Cash Flow Visibility#
Cash flow management in manufacturing requires visibility of three things simultaneously: what you owe and when it is due (accounts payable from AskBiz purchase orders synced to Xero), what you are owed and when it is due (accounts receivable from AskBiz customer orders synced to Xero), and what is currently in production and how long until it becomes a sale (AskBiz production batch status). Xero's cash flow forecasting uses these three data sources to project your bank balance forward — showing when cash will be tight and giving you lead time to act. For manufacturing SMBs, this forward visibility is the difference between proactive cash management (adjusting payment timing, drawing on a facility before the crunch) and reactive crisis management (calling the bank when the account is already in difficulty).
Working Capital Finance: Options for Manufacturers#
When operational cash flow management is insufficient to cover peak working capital requirements — typically during rapid growth, a large new contract, or seasonal inventory build — several finance options are available. Invoice financing (factoring or discounting) converts receivables to immediate cash. Trade finance (supply chain finance, letters of credit) provides supplier payment while deferring the cash outflow to the manufacturer. Stock finance loans against finished goods inventory. Revolving credit facilities from banks provide flexible borrowing headroom sized to working capital requirements. For UK manufacturers, the British Business Bank's guarantees underpin various lending products through accredited lenders. For Singapore manufacturers, Enterprise Singapore's Enterprise Financing Scheme includes working capital loan components. The right facility depends on your cash conversion cycle, your customer and supplier mix, and your financial track record.
Managing Cash Is as Important as Managing Production#
The most efficient production operation in the world cannot sustain a business that runs out of cash. For SMB factory owners, understanding and actively managing the cash conversion cycle — tracking DIO, DSO, and DPO as KPIs alongside OEE and yield — is a core management discipline. AskBiz and Xero together provide the operational and financial data to manage all of these metrics from one connected system. Factory owners who review their cash position weekly — not monthly — and act on forward-looking cash forecasts rather than historical bank statements consistently avoid the cash crises that constrain growth in otherwise healthy manufacturing businesses.
