hire software, not humans
Hire software, not humans. People are expensive. Software is not, usually because a lot of it is VC-subsidized in the name of growth. Take advantage of this by using Pilot or Bench instead of hiring an accountant or a CFO. Use Gusto to run payroll and benefits in five minutes. Because you are putting off hiring, you will also save money on all of the people-managing roles in your company, like an HR person and an office manager (see below). You may be surprised how far you can get with cheap software tools. For example, you can hire a human being to follow up with new customers every time someone signs up for your service or you can use automation tools like Zapier to send a follow-up email and to add those new customers to a queue to call later.
