Bayou Formula Lab

Plain-language finance for nonprofits, co-ops, and small businesses.

Bayou Formula Lab is a woman-owned finance studio in New Orleans. Guides, templates, and a free newsletter to help you actually understand your numbers.


What I do

I make the numbers make sense for the people running mission-driven organizations: Board Financials, a plain-language guide for board members; printable templates and trackers; and Spreadsheets & Coffee, a free newsletter with one finance idea per issue. Plain language, no judgment.

Work with me

I take on a small number of finance projects alongside my day job: cleaning up the books, setting up grant tracking, building board reports people can actually read. If you think your organization could use a hand, reach out and we'll see if it's a good fit.


Who it's for

Nonprofits, cooperatives, and minority-owned small businesses in the stretch between bookkeeper and CFO: grants with strings attached, payroll split across programs, an audit on the calendar, and a board that needs real numbers.

About Lindsey

I'm Lindsey Mayo, a nonprofit finance director and co-op board treasurer with about a decade in commercial lending, bank auditing, and nonprofit finance. I've seen the numbers from the bank, the operator, and the board table. I wrote Board Financials, a plain-language guide for board members, because everyone deserves to understand their own numbers.
