Producer prices rose 4.7% over the twelve months to July 2026 while consumer prices rose 3.4% (BLS, 13 and 12 August 2026). That 1.3 point spread is the definition of margin compression for a small business: what you buy is inflating faster than what you sell. The NFIB data from the same week shows owners are already losing the argument on price. The net percentage raising average selling prices fell seven points in July to net 31%, and net profit trends sat at negative 16% (NFIB, 11 August 2026).
The Cost Line Is Not Moving at the Headline Rate
Headline CPI is a poor proxy for what a business actually pays. Core CPI, which strips out food and energy, ran at 2.5% year over year in July. Energy ran at 14.7%, and gasoline at 24.6%. If your cost base includes delivery, fleet, plant, refrigeration or any material freight component, your input inflation is nowhere near 3.4%.
The producer price data tells the same story from the supply side. Final demand less foods, energy and trade services rose 4.7% over the year, and services for intermediate demand rose 5.1%. Intermediate demand services is the bucket that contains most of what a small business buys from other businesses: logistics, professional services, maintenance, insurance-adjacent services. That line is running above 5% while retail sales fell 0.6% in July (US Census Bureau, 14 August 2026).
| Measure | 12 months to July 2026 | What it tells you |
|---|---|---|
| CPI, all items | 3.4% | What your customers think inflation is |
| CPI, core | 2.5% | What the Fed is watching |
| PPI, final demand | 4.7% | What your suppliers are charging |
| PPI, services for intermediate demand | 5.1% | What your service inputs cost |
| CPI, energy | 14.7% | Your fleet, freight and utility exposure |
| Average hourly earnings | 3.2% | Your wage base, before any hiring |
Run those numbers against a business doing $2m in revenue at a 35% gross margin. If input costs rise 4.7% and prices rise 3.0%, gross margin falls to roughly 33.9%. On $2m that is about $22,000 of gross profit gone in a year, and because inputs are typically paid before revenue is collected, the cash effect arrives before the accounting one.
Margin Compression Shows Up in Cash First
This is the part that catches operators out. A P&L reports the margin change at month end, after the close. Cash reports it immediately, in the form of a slowly widening gap between what leaves and what arrives.
If your suppliers are on 30 day terms and your customers pay in 29 days plus nine days late, a cost increase hits your bank account roughly five weeks before the corresponding revenue does. Compression is a working capital event before it is a profitability event.
Xero Small Business Insights data for the second quarter of 2026 put average time to payment at 29.3 days, roughly nine days beyond terms, up from 28.3 days and 8.4 days late in the fourth quarter of 2025. Payment behaviour is deteriorating at the same time input costs are climbing. Those two trends compound, and a monthly view of the P&L will not show you the compounding until the quarter is over. That gap between profit reported and cash held is the reason profitable businesses still go bankrupt.
Four Ways to Respond, Ranked by Cash Impact
- Reprice selectively, not across the board. A uniform 4% increase invites customers to shop the whole list. Increases concentrated on your lowest-margin lines and your least price-sensitive segments recover more gross profit with less volume risk. Model the volume loss you can absorb before you send the notice.
- Shorten the collection cycle before you touch price. Moving average days to payment from 38 to 30 releases cash immediately and costs nothing in customer goodwill compared with a price rise. On $2m of revenue, eight days is roughly $44,000 of working capital.
- Renegotiate supplier terms, not supplier prices. Suppliers facing their own 4.7% input inflation will resist a price concession and may well accept 45 day terms. Terms are a cash lever that does not appear on the P&L at all.
- Reprice contracts with an index, not a number. For recurring or multi-year work, tie escalation to a published index rather than negotiating annually from scratch. It converts a difficult conversation into a contractual mechanic.
Model the Decision Before You Make It
The question that matters is not whether to raise prices. It is how much volume you can lose at a given increase and still be better off in cash terms. That is a scenario, and it takes about a minute to run properly.
| Scenario | Price change | Volume change | Gross profit effect |
|---|---|---|---|
| Hold price, absorb cost | 0% | 0% | Down, by the full input increase |
| Match input inflation | +4.7% | Unknown until tested | Flat if volume holds, negative past a threshold |
| Partial pass-through | +3.0% | Smaller expected loss | Down modestly, lower volume risk |
| Targeted increase on bottom quartile margin lines | +6.0% on 25% of revenue | Concentrated in least-profitable customers | Often the strongest cash outcome |
Fill those cells with your own numbers, not illustrative ones. The threshold you are looking for is the volume loss at which the increase stops paying for itself, and it is specific to your margin structure. Scenario planning exists precisely so this is a modelled answer rather than a guess, and the mechanics are the same as any other stress test, as covered in stress testing a 20 percent revenue dip.
