Raising Prices Is a Communication Job as Well as Arithmetic
A clear explanation and a visible effective date can reduce confusion when an offer changes.
Costs rise, the old price becomes difficult to sustain, and the owner quietly updates a sign. Regular customers discover the change only when paying. The arithmetic may be sensible; the surprise is avoidable.
Decide what is changing
Use your cost model to understand the pressure, then describe the new offer clearly. SBA planning and break-even resources can help organise that analysis. They do not supply a universal percentage that every business should add.

In a hypothetical service business, list the new price, when it starts and which work it covers. Distinguish new bookings from commitments already agreed. Check the terms of existing agreements rather than assuming they can be changed casually.
Give customers a usable explanation
You do not have to publish every private expense. You do need to make the transaction understandable. If the scope also changes, say so. A price increase hidden inside a confusing package is harder to assess than a plain adjustment.
Some customers may choose another option. That possibility belongs in the business decision. Clear communication cannot guarantee acceptance, but it lets customers respond to the actual offer instead of feeling ambushed at the moment of payment.
