Three disciplines. One delivery team. Every engagement.
AI Tax Compliance Solutions ships through a small, vetted partner network — application engineering, on-prem hardware, and CPA expertise — assembled per engagement so you get one team that owns the whole stack instead of three vendors who blame each other.
How an engagement is delivered
Most "AI accounting platforms" are run by one company. They are good at one of the three things you actually need — usually the software — and they outsource or wing the other two. ATCS is structured the opposite way.
Three independent firms supply the disciplines that an SMB private-AI bookkeeping system genuinely requires. Each carries its own license, its own SLA, and its own accountability. They are coordinated through ATCS, but the work, the warranty, and the signature on each layer come from the firm that does that work for a living.
The three roles map cleanly onto the three failure modes that derail most internal-systems projects:
- The software is shaky because the vendor never built a real internal system before — solved by an application partner who has shipped Laravel + Livewire + AI for production businesses.
- The hardware is wrong-sized or under-supported because the vendor doesn't actually rack servers — solved by an infrastructure partner whose day job is sizing, racking, and backing up real on-prem deployments.
- The tax positions are unsigned because the vendor isn't a CPA — solved by a licensed CPA partner who reviews handoffs and takes positions on returns.

Visit jameshenderson.onlineHow they supply support
JamesHenderson.online is the application engineering partner. Every Laravel route, every Livewire component, every AI tool definition, and every database migration in the platform was authored, reviewed, and is maintained by this firm. They run the same stack in their own production work, so the engineering bar is set by people who use the platform daily — not by people copying patterns from a tutorial.

MaryAnnHairCPA.com
CPA-ready handoffs, tax-season prep, and compliance review by a licensed Certified Public Accountant.
Visit maryannhaircpa.comHow they supply support
Mary Ann Hair, CPA is the licensed-professional partner. The platform refuses to give tax determinations — that's by design — and the CPA partner is what fills that gap. They review handoff bundles, take positions on returns where the engagement scope includes filing, advise on entity structure, and respond to IRS notices. The role is partnership, not replacement: the platform handles the prep work so the CPA's hours go to judgment, not data entry.
Clients who already have a CPA they trust keep that relationship — the handoff bundle is built so any CPA can open it and work from it. Clients who need a CPA, or want one with hands-on familiarity with the platform, can engage MaryAnnHairCPA.com directly.

Handoff bundle reviewVerifies the year-end package is complete and CPA-workable before the close cycle locks.

Disclaimer: Tax positions, entity-structure advice, and IRS representation are provided by the licensed CPA partner under a separate engagement letter. ATCS the platform prepares and surfaces; the CPA files and determines.
How the three layers integrate
JamesHenderson.online specs the AI inference workload (model size, concurrency, memory footprint). Texas Integrated Services translates that into the GPU + RAM bundle that runs it. The pricing calculator on this site is the artifact of that handoff.
Texas Integrated Services delivers the encrypted backup posture, the audit log retention, and the documented restore drills. Mary Ann Hair, CPA reviews that posture annually as part of compliance review and signs off that internal controls are in place.
The platform produces the handoff bundle, the 1099 list, the audit log. The CPA reviews it, takes positions on the return, files. The AI assistant explicitly refuses tax determinations and recommends CPA review — by design.
The three partners coordinate per engagement through a single project lead at ATCS. You do not chase three vendors. You do not arbitrate which firm owns a problem. The handoffs between layers — application to hardware, hardware to backup, books to CPA — are coordinated as part of the engagement.
Each partner still owns their own work, signs their own scope, and stands behind their own warranty. That separation is the point. It means the application engineer is not also the person who ought to be racking servers, and the CPA is not also the person who ought to be writing migrations. Each role gets the depth it deserves.
