All business models erode and grow weaker over time. Your job is to assess the model and make changes before it’s too late. If your profit isn’t what it once was, consider raising your prices — without raising your prices. The following list includes ideas you may want to try:
Revise the discount structure
Change the minimum order size
Charge for delivery and special services
Invoice for repairs on serviced equipment
Charge for engineering or installation
Charge for overtime on rushed orders
Collect interest on overdue accounts
Produce less of the lower margin models in the line
Write penalty clauses into contracts
Change the physical characteristics of the product
