Write the rules down
List who can get a discount, how large and for how long. Agents should not need to ask the founder every time for the standard cases.
Find out why they are asking
A request can mean the price is too high, the product is not used enough, or the customer is testing you. Ask one question before answering.
Offer a better fit first
A smaller plan, annual billing or fewer seats can solve the real problem and keeps your price intact.
Give a time-limited concession, not a permanent one
If you say yes, make it for a set period with a clear end date. Open-ended discounts are hard to unwind later.
Say no kindly and clearly
Thank them, explain what the price covers and name the options that do exist. Avoid apologising for the price.
Record what you gave
Add a tag and a note on the ticket. Without a record, the same customer gets a second discount a year later.
