Wihemi is a Bay Area finance operations consultancy. We diagnose what's broken in your financial back office, design the systems and processes to fix it, and operate those systems alongside your team — in English or Spanish.
QuickBooks is excellent at what it does. So is Xero. So is BILL. But none of them solve the problem most small businesses actually have — and that problem doesn't live inside the accounting system. It lives in the layer above it.
Every business hits this transition around $1M in revenue. The systems that worked when you were smaller stop scaling. The signs are familiar:
Decisions get made on what's in the account today — not what's owed, owned, or coming next week.
Reconciliation gaps grow. Numbers in the system don't match the bank. Nobody knows which is right.
Bills arrive and get paid — nobody confirms what's actually owed. Errors hide in plain sight.
Tax season is a frantic reconstruction project instead of a routine close. Substantiation is shaky.
Every engagement starts the same way — with a diagnostic. From there, you decide how far we go together.
The end state of the work: one screen that answers "how is the business actually doing?" — sales, vendor spend, margin, and cash, reconciled and current. No spreadsheet archaeology required.

Pricing reflects scope, not seniority. We do our own work — no junior staff billed at senior rates.
Bay Area family-owned travel agency operating across two countries, with multi-currency bookings and 20+ years of operating history.
The owner was making supplier payments with no way to verify whether an invoice was a duplicate, an overpayment, or even owed at all. Agent booking changes — modifications, cancellations, refunds — left no audit trail. Books had been kept on spreadsheets and bank statements; the tax preparer couldn't substantiate a return without cleaner records. The owner knew something was off but couldn't pinpoint it.
Built a custom booking and payment tracking system with full audit trail for every change, modification, and cancellation. Added a supplier payment verification workflow so invoices are matched to actual bookings before money goes out. Rebuilt records to capture every transaction at the moment it happens, in both currencies. Established a reconciliation cadence the team could actually follow.
Wihemi was founded by William Hernandez, a senior finance professional with more than 20 years of experience inside large corporations — building budgets, designing financial systems, negotiating vendor contracts, and partnering with executives on operational decisions.
"I spent two decades bringing finance discipline to companies that already had it. I'm now bringing that same rigor to businesses that have never had access to it."
Wihemi works in close partnership with a credentialed accountant who handles bookkeeping and tax. Together we cover the full finance function — from daily transactions to strategic advisory — for clients who need more than a bookkeeper but don't need (or can't afford) a full-time CFO.
We serve in English and Spanish with cultural fluency that comes from decades in the Bay Area. Finance touches every part of the business — and the conversation should happen in the language the owner thinks in.
A 30-minute discovery call costs nothing and commits you to nothing. We'll ask about your business, your numbers, and where you're stuck — and if we can help, we'll tell you how. If we can't, we'll tell you that too.
