If you need cash fast, there’s nothing like having a sale to increase your bank account quickly. Here are ten excuses you can use to tell your customers you’re having a sale.
1. It’s Your Birthday (or Your Business’s Birthday) 
We all feel generous on our birthday, so why not have a sale on your special day. You can even tie to discount amount to your day of birth. For example, if you were born on the 14th, then you can offer customers 14% off.
Similarly, you can hold an anniversary sale on your business’s anniversary date. It’s a good way to let customers know how long you’ve been in business.
2. Your Partner Is on Vacation
If you have a business partner, you can use the excuse, “When the cat’s away, the mice will play.” You can pretend that your partner knows nothing about the sale, but has left you in charge and you’re going to have this sale. The customers will enjoy the reason and feel like they are getting away with something fun.
3. Holidays
Most stores have holiday sales, and you can too. There are so many unusual holidays that you can tap into just in case the holidays are at an inconvenient time. Here’s a website that will give you a list of special days, weeks, and holidays: http://www.holidayinsights.com/moreholidays/
4. The Full Moon 
Why not? It might be the best sale you’ve ever had. The next full moon is June 2, 2015, and July has a blue moon (when two full moons occur in one month) on July 31, 2015.
5. Small Business Saturday
November 28, 2015 is Small Business Saturday. It’s one day after Black Friday and the Saturday before Cyber Monday. Small Business Saturday is relatively new, but has been gaining momentum in the past few years. 
6. Tax Holidays
In some states the sales tax authority provides exemptions for a few days on selected categories of items. For example, in August, Texas allows one weekend where sales tax does not have to be paid or collected on school supplies. You may not even have to mark down your items to generate a crowd for sales tax holidays. Unfortunately, this does not apply here in New Hampshire. For more information, here’s a Wikipedia page on it: http://en.wikipedia.org/wiki/Tax_holiday
7. Old Inventory Items or Overstock Condition
A great reason to have a sale is when you have old inventory items you need to clear out. Similarly, if you’re overstocked on certain items, a sale will help them move.
8. Your Kid’s College Tuition Is Due
You can have a lot of fun by advertising that you simply need to make your tuition payments. Customers will get a smile out of helping you out and relating to a familiar need.
9. The Stock Market
If the stock market goes up or down, you can have a sale based on its performance.
10. Seasonal Dates 
Dates such as the first day of summer, Spring Equinox, or even April 15th, tax day (in the U.S.) can be potential sales days for your business. Think about seasonal dates related to your industry.
