I am in 7th grade and just starting my company any suggestions marketing tips and tricks you vets can tell me
The other guys are correct about insurance and being organized.
The guy who suggested taking care of your customers has given you the most important advice.
My son and I started from scratch to make a little money part time. We did get insurance and business cards. We did free advertising on an area website and that is all the advertising we did.
If you do a GOOD job and always give your customers MORE than you promise, the money will take care of itself. In your situation, word of mouth recommendations will get you all the business that you can handle. If you do that GOOD job and treat your clients right, you will get that word of mouth business. My son and I took our ad down. We haven't needed it for quite a while now.
One other piece of advice. Don't mess around with deadbeats. If they don't pay, don't mow. If they owe you for one mowing, don't be afraid to ask for the money up front when you go back. No pay, no mow. Better to lose one cutting than 2 or 3.
Keep good records of receipts, expenses, and dates of service.
If you do this business successfully, by the time you get to the twelfth grade, you'll have learned more about making a living than most folks do their whole lives.
Good luck to you.
