I’ve mentored and advised countless entrepreneurs over the years, and I almost always start with the same piece of advice: Don’t ignore the low hanging-fruit.

This mantra refers to the easy things you can do for your business today that can have an outsized impact—quick wins that give you the biggest bang for your buck.

The easiest low-hanging fruit to grab for a service business? Text reminders.

As a client, you’ve probably booked a service or made a restaurant reservation and received a text reminder a few days prior to the appointment. “We’re excited to see you at 8 p.m. on Tuesday. Respond YES to confirm,” the text might say. Services send these texts for one simple reason: They reduce the chances of a cancellation and give you an option to reschedule in advance.

Service providers—from aestheticians to personal trainers to tattoo artists—know that no shows are killers for a business’s bottom line. That hour you spend checking your watch, waiting for a client to arrive could be spent actually providing a service—and would end with a client swiping their credit card.

Text reminders are proven to reduce cancellations:

According to our research, 66 percent of service providers using Schedulicity text reminders see a reduction of at least one cancellation per month.

What does that mean for your bottom line? Let’s do the math. If you use Schedulicity, text reminders cost $5 per month or $10 for multi-providers. Let’s assume that you work alone and your average service charge is $50. If you get even one less no-show per month as a result of using text reminders, your return on investment is 900 percent. That’s incredible.

But here’s the kicker: According to our research, close to fifty percent of Schedulicity users do not have text reminders turned on in their scheduling software. This is a classic example of ignoring low-hanging fruit—an easy, cost-effective way to bring in more money without breaking a sweat.

So let’s boil it down. Almost half of you are losing out on your biggest bang for the buck. My goal as a mentor is to make you a better entrepreneur and business owner—and to help you succeed. If you only take one piece of advice from me, this is it: Turn on text reminders in your scheduling software. It’s quick, effortless, and seriously delivers.
