Your prices are not ten years old. They are ten years of unabsorbed cost increases deep, which is a different and considerably worse condition, and the difference is why the usual advice about raising prices gently does not apply to you.
A business that moves price every year is making a small adjustment against a small drift. A business that has not moved price in a decade is carrying a compounded gap, and the arithmetic of that gap is unforgiving in a way that most owners have never sat down and calculated. Before you decide how to fix it, you have to know which version of the problem you have, because there are three and they have different answers. The wider context for all of this is in the guide to modernizing a family-owned manufacturer, and none of what follows works without the numbers described in tax books versus management books.
Raising prices after a decade is not one decision, it is a diagnosis followed by a sequence. Identify whether you have a drift problem, a mix problem, or a courage problem. Rebuild the cost base so the ask is arithmetic rather than assertion. Then move the underpriced work first, individually, in conversation, and never through a blanket letter.
Which price problem do you actually have?
Three patterns, and almost every long-flat manufacturer is one of them. Telling them apart takes an afternoon with last year’s job data and it determines everything downstream, so do not skip it in favor of a general increase.
The first is drift. Prices are broadly right relative to each other but the whole schedule has fallen behind input costs. Margin has eroded evenly across the book. The fix is a general move, and it is the easiest of the three because it can be explained in a single sentence anybody understands.
The second is mix, and it is by far the most common. The average looks survivable because a minority of the work is carrying everything and the rest is at or below water. Here a general increase is exactly the wrong instrument: it takes the same percentage from your best-margin volume, which is the volume most likely to leave, while barely touching the underpriced work that caused the problem. The method I use for sorting this is the 80/20 Matrix of Profitability, which puts the work in a grid by margin and by volume so you can see which quadrant you are actually fixing rather than moving everything at once.
The third is courage. The numbers are known, the gap is identified, and nothing has happened for four years because the person who would have to make the call has a twenty-year relationship with the customer. This one is not an analytical problem at all, and treating it as one produces another year of analysis.
Run the diagnosis on real job-level margin, not on quoted margin. Quoted margin tells you what you intended. It has nothing to say about what happened.

What ten flat years actually did to your margin
Do the arithmetic before you do anything else, because the number is almost always worse than the instinct and the instinct is what has been governing the decision.
Take a job priced at 100 with a cost of 68, so a gross margin of 32 percent. That was defensible when it was set. Now assume input costs, which is materials, wages, freight, utilities and everything else, rose at an average of three percent a year. Three percent is modest and most industrial businesses have seen more over the last decade. Compounded over ten years, three percent is not thirty percent. It is 34 percent, because each year compounds on the last. Your cost of 68 is now about 91. Your price is still 100. Your gross margin is now under nine percent.
At four percent average input inflation the same job is at 48 percent higher cost, and the margin has gone negative. This is illustrative arithmetic rather than a claim about your specific business, but run it on your own numbers and the shape will not change.
What makes this hard to see from inside is that it never happened in a month. Nobody ever made a decision that cost twenty-three points of margin. Twelve hundred small non-decisions did, each of them individually reasonable, and the P&L absorbed it by degrees while overall profit stayed positive on volume.
The practical consequence worth stating plainly: a business in this condition usually cannot recover with a single three or five percent move. The gap is structural and the correction has to be sized against the gap rather than against what feels polite.
Will you lose customers?
Some, and the ones you lose will disproportionately be the ones you should have lost, provided you move the right accounts rather than all of them. That proviso is the whole game.
What I have consistently seen in industrial businesses is that the fear is calibrated to the wrong reference point. Owners imagine the reaction of their most price-sensitive customer and apply it to the entire book. In practice the accounts most likely to accept a correction are the long-tenured relationship accounts, precisely because switching costs are high, your quality history is known, and the buyer on the other side has been through their own cost increases and expects yours. The accounts most likely to leave are the transactional ones you won on price, which are also the ones sitting in the quadrant you were trying to fix.
Size the risk honestly rather than emotionally. For each account you intend to move, write down what it would cost you if they left: the contribution margin you lose, the capacity you free, and what else that capacity could do. In a shop running near capacity, losing a low-margin account is frequently a gain, and nobody has ever calculated it because the revenue line is the only thing anyone looks at.
Expect a range rather than a number. Move a set of underpriced accounts by a meaningful amount and some fraction will push back hard, a smaller fraction will genuinely go, and the rest will absorb it with less drama than you have been imagining for four years.
The sequence that works
Order matters more than magnitude here, and the most common failure is a blanket letter sent to everyone at once, which converts a set of individual commercial conversations into a single company-wide event that invites a coordinated response.
- Rebuild the cost base first. Actual absorbed cost per job, with real overhead allocation and captured setup time. Without this every conversation becomes an assertion against the customer’s assertion, and you will lose that exchange.
- Segment the book into four groups. Underpriced and strategic, underpriced and transactional, correctly priced, and the small group you are deliberately willing to lose. Each gets a different move and a different conversation.
- Start with the underpriced transactional accounts. Lowest relationship risk, highest margin gap. You also learn how the market actually responds before you go anywhere near the accounts that matter.
- Move the strategic accounts second, individually and in person. Whoever owns the relationship makes the call, with the cost reasoning available if asked. Never a letter, never an email, never through a portal.
- Reset the quoting rule so this cannot recur. Tie the shop rate and the material basis to an input that updates on a schedule, so next year’s price moves without requiring anyone to be brave.
- Put price on the weekly agenda permanently. One line, every week, reviewed by the same people. Ten years of drift is a governance failure before it is a pricing failure.
Step five is the one that determines whether you are solving this or repeating it in 2036. Everything above it is remediation. Only step five is a fix.
What do you do when a customer pushes back?
You expect it, you have decided your floor in advance, and you do not negotiate the increase in the same conversation in which you announce it. Those three rules handle most of what comes back.
Deciding the floor in advance is the part people skip and it is the part that costs money. Before the call, write down the number below which you would rather lose the account, and why. Then, whatever happens in the conversation, you are comparing an offer against a decision you made with a spreadsheet rather than against the emotional weight of a twenty-year relationship at the moment somebody is unhappy with you.
When the pushback comes, the useful response is almost never a defense of the increase. It is a question about what would make it workable. Frequently the answer is not price at all. It is a longer lead time that lets you batch, a minimum order quantity that kills your setup cost, a firmer forecast, or payment terms. Those concessions can be worth more to you than the points you gave up, and the customer experiences them as having won something.
If a customer genuinely will not move and the account is below your floor, let it go cleanly and without a final offer. Reversing under pressure teaches that customer, and every other customer they talk to, that your prices are a first position rather than a price. That lesson costs more than the account.
On Monday morning, take one job you shipped last week, calculate what it actually cost using real hours and real overhead, and compare it to what you charged. That single number is the argument, and you do not have a pricing project until you have it.
