Bookkeeping That Keeps You Audit-Ready
CPA-supervised monthly bookkeeping, catch-up and cleanup, and clean QuickBooks Desktop to Online migrations, in flat monthly packages, never an hourly meter.
G&S Accountancy provides CPA-supervised bookkeeping for businesses across Southern California: monthly bookkeeping, catch-up and cleanup, QuickBooks Desktop to Online migration, reconciliation, and financial reporting, offered in flat-rate monthly packages.
Bookkeeping, done right
Books you can build decisions on
Bad books cost more than they seem to. They hide cash-flow problems, inflate your tax bill, and fall apart the moment a lender or a tax agency asks questions.
G&S delivers bookkeeping that is accurate, reconciled, and supervised by CPAs, so the same numbers that run your business also stand up to a financing application or an audit. And because we price in flat monthly packages rather than by the hour, you get a predictable cost and no incentive to drag the work out.
What our bookkeeping covers
From day-to-day categorization to a clean software migration, everything your books need in one CPA-supervised engagement.
Monthly Bookkeeping
Categorized transactions, reconciled accounts, and a clean set of books every month, so you always know where the business stands without waiting until tax time.
Catch-Up & Cleanup
Months or years behind? We reconstruct, reconcile, and correct your books until they are accurate and audit-ready, then keep them that way.
QuickBooks Desktop to Online Migration
We move you off aging Desktop files onto QuickBooks Online cleanly, preserving history, fixing what is broken, and setting up a chart of accounts that actually reports.
Bank & Credit Card Reconciliation
Every account tied out to the statement, every month, so discrepancies surface early instead of at year-end when they are expensive to fix.
Financial Reporting
Profit-and-loss, balance sheet, and cash-flow reporting you can read, with a CPA available to explain what the numbers mean for your decisions.
Payroll & Sales-Tax Coordination
We keep bookkeeping aligned with payroll and California sales-tax obligations so filings reconcile and nothing slips through the cracks.
Simple, flat-rate packages
Tiered packages, not an hourly rate

QuickBooks Desktop to Online
Migrate to QuickBooks Online without losing your history
Intuit is steadily pushing users off QuickBooks Desktop, and a do-it-yourself migration almost always drags broken data, duplicate accounts, and unreconciled balances into the new file. We treat the move as an accounting project, not a button press.
- Assess and clean the Desktop file before conversion
- Preserve transaction history and reconciliations
- Rebuild a chart of accounts that reports cleanly
- Verify balances and confirm reports tie out post-migration
- Train your team on the workflows they will actually use
How onboarding works
Getting started is straightforward, whether your books are current or years behind.
Discovery & books assessment
We review the current state of your books, your software, and where you want to get to. You get an honest read on what cleanup, if any, is needed.
Cleanup or migration
If you are behind or moving off QuickBooks Desktop, we get you to a clean, accurate baseline before ongoing work begins.
Onboard to a monthly rhythm
We set the chart of accounts, connect feeds, and establish a repeatable monthly close so reporting is consistent.
Ongoing bookkeeping & review
Each month your books are reconciled and reported, with a CPA available to answer questions and flag what needs attention.
