Trusted by CPA & EA Firms Across the U.S.
A growing group of firms that have made BusAcTa part of how they work
We're not a staffing agency and we're not a generic BPO. We're a CPA-led team that learns how your firm works and operates inside your own software.
"There's no anonymous pool of workers here. We assign one dedicated team to your firm and keep it there."
BusAcTa Advisors is a CPA-led offshore accounting and tax preparation firm founded in 2019. A Big Four-trained CPA runs all engagement work. Most of our clients are U.S. CPA and EA firms with 5 to 20 people — small enough that every client file matters, busy enough that they need offshore accounting support to scale without adding local headcount.
A qualified CPA leads every project, and every file goes through a two-layer internal review before it reaches you for sign-off.
Your clients never find out we're involved. Your team always knows exactly where each file stands.
A licensed CPA oversees every engagement.
Your clients get the same assigned team, not a shared preparer pool.
Signed NDA, encrypted transfer, role-based access.
A five-stage review runs on every file we send back.
A predictable onboarding path designed by CPAs who have scaled U.S. firms for 5+ years.
Every engagement overseen by a licensed CPA.
Day 1Your clients get a named, assigned team — not a shared preparer pool.
Day 2-3Signed NDA, encrypted transfer, role-based access.
Week 1-2Five-stage review framework applied to every single file we deliver.
Week 3+Offshore bookkeeping, tax prep, and accounting — prepared by our team, CPA-reviewed, and delivered back to you ready to sign off. We work inside your software, follow your review style, and keep your clients' names off any communication that isn't yours.
We handle your clients' day-to-day bookkeeping in QBO, Xero, NetSuite, or Sage. Transactions coded correctly, accounts reconciled on schedule, and a month-end close that doesn't drag into the following month. Your team gets files that are ready to review, not ready to clean up.
Every firm carries its own rules and its own rhythm. We shape the work around them, whether that means clearing a tax-season backlog or keeping property-level books straight, and we hand back files that are ready for your review.

Don't see your software? We adapt to your stack.
Let's TalkPicking an offshore partner comes down to more than the rate. It comes down to whether you can trust them with your clients' data and your firm's name. We built our setup around what U.S. CPAs and EAs actually need to see.
We align to IRS Circular 230, use role-based access and encrypted portals, and sign an NDA before any data changes hands.
You get the same named, CPA-supervised people every time. They learn your clients, your software, and how you like things reviewed.
A licensed CPA reviews every engagement before it lands on your desk, so what you open is ready to send out.
Drake, CCH, Lacerte, UltraTax, QBO, Xero. We start working in your tools on day one, with nothing for your staff to teach us.
Every file moves through five internal review stages covering the numbers, the formatting, and the final sign-off. You shouldn't have to redo our work.
Most work comes back in 36–48 hours, and we keep extra capacity on hand for the crunch weeks of tax season.
Security, turnaround, software fit, and what the free trial actually covers. Here are the answers we'd give you on a call.
Three options: pay-per-return from $59, a Dedicated CPA Crew from $2,950/mo (1 senior + 2 staff, CPA-supervised), or a custom multi-crew / virtual CFO engagement. No setup fees, month-to-month after a 30-day pilot, and a clear written SLA on every engagement.
We are fully aligned with IRS Circular 230 and treat every engagement as confidential by default. NDAs are signed before any data exchange, access is role-based and least-privilege, and all work happens inside encrypted client portals or your own systems. We never store client data on local machines, USBs are disabled, and session activity is logged. Annual security training is mandatory for every team member.
We work directly inside your stack, with no exports and no rework. Tax: Drake, CCH Axcess, Lacerte, UltraTax, ProSeries, ATX, TaxDome. Accounting: QuickBooks Online and Desktop, Xero, NetSuite, Sage Intacct, Wave. Workflow: Karbon, Canopy, Jetpack, SmartVault, ShareFile. If you use something different, we'll pick it up quickly.
Our 36–48 hour turnaround is written into the agreement, not just a hope. Standard tax returns and routine bookkeeping files come back within 36–48 business hours of our receiving complete information. Complex returns (multi-state, K-1 cascades, consolidated 1120s) get a defined delivery date upfront. During peak season we add capacity ahead of time so deadlines hold.
After a 30-minute discovery call, we build a written SOP for your firm: software, naming conventions, review style, escalation paths. You're assigned a named team with a CPA reviewer. Work is requested via your existing tool (Karbon, email, portal — your call), tracked transparently, and delivered review-ready. Weekly check-ins, monthly performance reviews, no hidden fees.
You choose either 5 tax returns OR 10 hours of accounting/bookkeeping work — completely free, no credit card, no commitment. A CPA scopes the work, a dedicated team executes it inside your software, and every file passes our 5-stage QC before it lands on your desk. You evaluate the quality, communication, and turnaround before deciding to engage further.
Pay-per-return starts from $59 per 1040. A dedicated CPA crew (one senior accountant, two staff, CPA-supervised) runs from roughly $3,000–$6,000/month — significantly less than a single full-time U.S. hire. Most firms see a 50–60% reduction in per-return cost. No setup fees, and every engagement starts with a free 30-day pilot.
Yes. We operate under a security framework aligned to IRS Circular 230 and SOC 2 principles. Every engagement begins with a signed NDA. We use encrypted portals, role-based access, no local data storage, disabled USB ports, session logging, and mandatory annual security training for every team member. Your clients' names never appear in any external communication.
Three differences: a licensed CPA leads and reviews every engagement (agencies just place workers); you get a named dedicated team, not a rotating pool; and we work directly inside your software — Drake, CCH, QuickBooks, Xero — with no exports or reformatting. Every file also passes a 5-stage internal review before reaching your desk.
