Price swings in raw materials can wipe out margins if you buy at the wrong time
Raw material prices move in cycles, but the signals come from your own data long before the market reports it. If you wait for suppliers to call with a price hike, you’re already too late. Factories lock in prices before volatility hits by tracking three things: what you actually use, what you paid last time, and what competitors are paying now—all integrated into the ERP system.
The problem extends beyond the price tag: overstocked warehouses when prices fall, rushed orders during spikes, and overtime wages to meet sudden demand. These hidden costs don’t appear in the purchase ledger—they’re buried in production schedules and bank reconciliations. The factories that avoid them treat procurement like a production line: every purchase order is a batch, every supplier a machine, and the ERP system tracks the yield.
Your ERP already holds the data to predict price swings—here’s how to find it
Most factories track purchases but rarely reconcile them with actual usage. The discrepancy reveals where price volatility impacts costs most. For example, a 3 per cent scrap rate on a 500-kilo fabric roll means 15 kilos of waste—enough to justify a price hike if the supplier assumes full orders. However, tracking scrap per batch in the ERP strengthens negotiations by proving you’ll only order what’s needed.
Facteno’s Purchase & Suppliers module links purchase orders to stock consumed in production. Filter for ‘unmatched GRNs’ to spot unused inventory. A 20 per cent surplus of last month’s fabric suggests overordering; cross-referencing with supplier lead times helps optimize future orders and reduce holding costs during price drops.
Here’s the mechanism:
- Run a ‘Stock Usage vs. Purchase Order’ report in your ERP, grouped by material and supplier.
- Compare ‘quantity received’ with ‘quantity consumed in production’—the difference indicates waste or overordering.
- Consistent gaps signal process issues (e.g., cutting errors); random gaps point to procurement flaws (e.g., panic buying).
- Use the ‘Supplier Performance’ dashboard to identify on-time suppliers and those causing excess stock.
This approach isn’t just about invoice savings—it’s about timing price locks. If your ERP shows 80 per cent usage, negotiate discounts for smaller, frequent deliveries by proving you won’t tie up supplier capital.
How to spot the early signs of a price hike before suppliers announce it
Suppliers don’t call to say prices are rising—they wait until they’ve already raised them. The factories that avoid this trap monitor three signals in their ERP:
- Purchase order lead times: If a supplier suddenly extends delivery from 14 to 21 days, they’re either short of stock or expecting a price rise. Check the ‘Supplier Lead Time Trends’ report in Facteno’s Purchase & Suppliers module. A 20 per cent increase in lead time is a red flag.
- Stock turnover ratios: If your fabric inventory sits for 45 days instead of 30, either demand dropped or prices are about to. Run a ‘Days of Stock on Hand’ report and compare it to your sales forecast. A 15-day spike means you’re holding too much—and suppliers know it.
- Supplier payment terms: If a supplier switches from ‘net 30’ to ‘prepayment’, they’re hedging against a price rise. Track ‘Supplier Payment Terms’ in the ERP to spot this before it affects your orders.
These signals don’t come from market reports—they come from your own data. For example, if your ERP shows that every time cotton prices rise, your suppliers extend lead times by 10 days, you can place orders 14 days earlier to lock in the current rate.
The key is to automate these checks. Set up alerts in your ERP for:
- Purchase orders where the lead time exceeds the supplier’s average by 15 per cent.
- Inventory levels that rise 20 per cent above the rolling 3-month average.
- Suppliers who change payment terms without explanation.
Why reconciling purchase orders with actual usage cuts overbuying by 15–25 per cent
Factories overbuy raw materials due to overestimation of needs or panic during price hikes—both cost more than the material itself. Holding excess stock ties up capital, while rushed orders increase scrap and waste. The fix? Reconciling purchase orders with actual consumption, a feature most ERPs support but few factories use effectively.
For example, if your ERP shows 10,000 kilos of fabric ordered but only 8,500 kilos used, the gap could stem from:
- Waste from cutting errors (tracked in Quality Control).
- Overordering due to poor demand forecasting.
- Unused stock from idle production lines.
Without addressing this gap, overordering repeats—and costs escalate when prices rise. Facteno’s Inventory & Stores module provides a ‘Purchase vs. Consumption Reconciliation’ report, revealing:
| Cost Driver | When It Lands | What Makes It Move |
|---|---|---|
| Purchase order quantity | When the GRN is raised | Supplier lead time, production schedule changes |
| Actual consumption | End of production month | Scrap rates, machine downtime, order cancellations |
| Warehouse holding cost | Monthly, tied to stock levels | Interest rates, storage fees, obsolescence risk |
| Rush order premium | When lead times extend | Supplier capacity, transport delays, price hikes |
The table highlights visibility, not just savings. If rush orders add 8 per cent to costs, delays become costly. Similarly, holding costs—like 1.2 per cent of stock value monthly—push factories to order less when prices dip.
How to use ERP to negotiate better terms when prices rise
Suppliers raise prices when they have leverage—either because you’re their only customer in the region, or because you’ve given them no reason to offer better terms. The factories that avoid this trap use their ERP to prove they’re a low-risk buyer.
1. Show consistent usage: If your ERP reports 90 per cent order fulfillment, ask for volume discounts on smaller, more frequent deliveries. Suppliers prefer steady business.
2. Leverage payment terms: If your ERP shows you pay suppliers within 10 days, negotiate early payment discounts. For example, a 2 per cent discount for payment within 7 days could yield a 10 per cent return on capital.
3. Commit to long-term contracts: If your sales forecast shows stable demand, lock in prices now. Facteno’s Sales & Order Book module ties purchase orders to confirmed sales orders.
4. Threaten to switch suppliers: If your ERP shows three suppliers for the same material, with one 5 per cent cheaper, use that as leverage.
The key is to pull this data before negotiations. Facteno’s Reports module includes:
- A 12-month trend of what you paid per kilo.
- Actual usage per month.
- Lead times and delivery reliability.
- Payment terms and discounts taken.
This isn’t bluffing—it’s fact-based negotiation. If a supplier cites rising prices, reply with: ‘Our data shows we’ve paid X per kilo for six months. Can you match that for a three-month contract?’
What goes wrong three months in—and how to spot it before it happens
Most factories focus on the invoice price, but the real costs emerge later. Three months after ordering, you may face:
- Quality issues from rushed deliveries: Overordering to avoid price hikes leads to excess fabric, longer drying times, defects, and higher scrap rates. Facteno’s Quality Control module tracks defect rates by batch.
- Warehouse congestion: Extra stock occupies space, slows operations, and requires temporary labour. Check the ‘Warehouse Turnover’ report in Inventory & Stores—a turnover below 8 means excess stock.
- Supplier favouritism: Panic-buying from one supplier risks price hikes later. Facteno flags ‘single-supplier dependency’ in the ‘Supplier Risk’ dashboard.
- Hidden holding costs: Storage fees, insurance, and obsolescence accumulate silently. Facteno’s Finance & Accounts module links stock values to warehouse costs.
Run a ‘Post-Purchase Impact’ report quarterly, combining:
- Defect rates from Quality Control.
- Warehouse turnover from Inventory & Stores.
- Supplier performance from Purchase & Suppliers.
- Actual material cost per piece from Product Costing.
The trade-off most articles skip: when to hold stock vs. when to order just in time
Holding stock protects you from price rises, but it costs money. Ordering just in time saves capital, but it leaves you exposed to delays. The factories that balance this trade-off use their ERP to answer three questions:
- How long does it take to replenish? Check the ‘Supplier Lead Time’ report. If it’s 21 days, you need at least 21 days of stock on hand to avoid shortages.
- How much does it cost to hold? Run a ‘Warehouse Cost per Kilogram’ report. If it’s $0.10 per kilo per month, holding 1,000 kilos for three months costs $30—enough to justify a 3 per cent price lock-in.
- How volatile is the price? Compare the ‘Monthly Price Trend’ for your material. If it swings by 10 per cent every six months, holding stock makes sense. If it’s stable, just-in-time ordering is better.
The ERP doesn’t decide for you—it gives you the numbers. For example, if your fabric price has risen 15 per cent in the past year but your warehouse cost is only 5 per cent of material value, holding stock is cheaper than risking a shortage.
Facteno’s Business Control Centre lets you see all three factors on one screen:
- Current stock levels vs. safety stock.
- Supplier lead times vs. production demand.
- Price trends vs. holding costs.
Use this to set ‘dynamic reorder points’. For example:
- If lead time is 14 days and demand is steady, order when stock hits 15 days’ supply.
- If prices are rising, increase the buffer to 25 days’ supply.
What to do next week: three tests to run in your ERP
Start with these three tests this week:
- Run a ‘Purchase vs. Consumption’ report and identify one material where you overordered last month. Adjust your next purchase order to match actual usage.
- Set up an alert in your ERP for any supplier who extends lead times by 10 per cent or more. Place your next order 14 days early to lock in the current price.
- Pull a ‘Supplier Negotiation Pack’ for your top three materials. Use the data to ask for better terms—either a volume discount or an early payment discount.
These tests don’t require new software—they use the data you already have. If your ERP can’t do this, it’s not the right tool. Facteno’s pricing starts at $149 per month for up to 10 users, and includes all the modules needed to run these reports.
