A QuickBooks ProAdvisor fixes a California file that’s drifted — flat-rate district sales tax, 1099/W-2 misclassification, unreconciled accounts, ASC 606 revenue errors — and brings it to a CPA-ready standard. Fixed-fee, all 58 counties.
If your file needs our paid diagnostic first, its fee is credited in full against the cleanup. Either way, you get a fixed fee in writing before any work starts.
California rule: sales and use tax records should be kept for at least four years unless the CDTFA gives written authorization to destroy them sooner; the cleanup rebuilds every period inside that window from source documents. Source: CDTFA Publication 116.
California QuickBooks cleanup fixes a file that is structurally wrong, for a fixed fee of $1,200–$15,000+, from days for one issue to weeks for a multi-year rebuild. We reconcile each bank and credit-card account to source statements, investigate unmatched balances, document corrections and hand over a period-by-period exception register. Flat-rate district sales tax is reset by location.
They took something that felt overwhelming to me as a first-year business owner and made it simple.
What stood out the most was TechBrot Inc’s attention to detail.


When a file drifts in California, check these three first, starting with sales tax.
Most California cleanups share the same root causes — the ones a generic bookkeeper created or never knew to fix.
Most California cleanups aren’t carelessness — they’re a generic setup that never knew about district sales tax, AB5, or ASC 606. Fixing the root cause, not just the symptoms, is what makes a cleanup hold.
Once the file is CPA-ready, the same preparer can keep it that way in monthly bookkeeping and extend into advisory when the numbers are trustworthy.

Every cleanup step in order — opening balances, reconciliations, undeposited funds, the chart of accounts — and how to tell what your file needs.
OpenA scope-based estimate for a focused, standard, or complex cleanup from your months behind, number of accounts, and transaction volume.
OpenIf the same error keeps coming back after a repair, the file itself is the problem — start with the error, then decide whether it needs a cleanup.
OpenThe common California problems: district sales tax set to a flat statewide rate (corrected to the right combined rate by location), 1099/W-2 misclassification under AB5, unreconciled accounts, Undeposited Funds and Opening Balance Equity errors, and ASC 606 revenue mistakes for SaaS and agencies. We bring the file to a CPA-ready standard and document every change.
District sales tax configured at a flat statewide rate instead of the correct combined rate by customer location. California’s rate is sourced by location, so a flat rate quietly under- or over-collects and the CDTFA return stops tying. We rebuild the sales-tax setup to district rates and reconcile it — it’s the single most frequent fix.
Fixed-fee against a written scope, never open-ended hourly — typically $1,200–$15,000+ depending on how many months or years are involved and how deep the problems run. The free file review tells you what it needs before any work begins.
A focused single-issue cleanup can take days; a multi-year, multi-problem rebuild runs weeks. We scope it in writing first and prioritize anything blocking a tax filing, a loan, or a sale.
Yes — it’s a common California cleanup. SaaS companies that booked annual contracts on signing instead of deferring, and agencies booking pass-through media as gross revenue, both overstate revenue. We correct the deferred-revenue schedule and gross-vs-net treatment so the books are defensible; the tax positions stay with your CPA.
You get a CPA-ready file and a written summary of what was fixed. You can then move into monthly bookkeeping with the same preparer so the file stays clean and doesn’t drift again.
Yes — a file set up by someone else, in-house or by a previous bookkeeper, is a normal starting point. We work in your existing QuickBooks Online or Desktop file, diagnose what went wrong, and fix it without making you start over.
