Flat-fee, retirement plans for business owners (SEP, solo 401k) financial advisors in South San Francisco, CA
The right financial advisor for you depends on how you weigh location, expertise, experience, the clients they typically serve, and how they work with you.
If you own a business and want to set up a retirement plan like a SEP or solo 401(k), you need an advisor who understands how these plans fit your unique business cash flow and tax situation. A common mistake is choosing a plan without considering how fees and plan features affect your long-term savings and business finances. Flat-fee advisors charge a set price, so you can expect clear costs without surprises.
- Plan type suitability. Confirm how they evaluate whether a SEP or solo 401(k) best matches your business size and income variability.
- Contribution strategy. Ask how they help balance maximizing your retirement savings with maintaining enough cash flow for your business needs.
- Tax impact awareness. Make sure they consider California’s high income taxes and how Proposition 13 limits property tax growth when advising on plan benefits.
- Fee transparency. Since these advisors work on a flat fee, check how that fee covers ongoing plan management and advice.
Here are top matches to get you started. Review each profile to compare experience, credentials, and approach.

We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
