Who Should Choose Lettuce
Lettuce makes sense for specific types of solopreneurs at certain business stages. Here's how to know if it's right for you:
|
You're earning over $80,000 annually and hitting the threshold where S Corp tax savings become meaningful. At this level, Lettuce typically saves users $10,000-$15,000 per year. That’s far more than the platform costs. |
|
|
You're hands-off with financial tasks. You'd rather have systems run automatically than customize every detail yourself. Learning tax strategy or managing compliance doesn't interest you. You want it handled so you can focus on client work |
|
|
Tax savings matter more to you than financial flexibility. You're willing to commit to the S Corp structure and its requirements (reasonable salary, payroll schedules, corporate formalities) in exchange for automated savings and compliance. |
|
|
You want protection built in. Audit defense, IRS-compliant documentation, and a savings guarantee give you confidence that everything is handled correctly. You're not comfortable navigating tax decisions alone or coordinating multiple providers. |
Making Your Choice: Lettuce vs. Mercury
The Lettuce vs. Mercury decision comes down to how you want to run your business. Both platforms work well for solopreneurs, just in different ways. Pick the one that matches your revenue level, work style, and priorities.
The right answer depends on where you are now and where you're headed. If banking flexibility is your priority, Mercury delivers that focus. If tax savings and automation matter most, start with Lettuce.
