AI + CPA

The best of both
worlds.

Celestia builds custom tools to clean up your finances. Whether it's random receipts, bank statements, credit card data, timesheets, inventory, or vendors — we connect everything, down to the most minuscule piece of data, so you can see exactly what's happening.

Powered by Claude AI and backed by licensed CPA oversight, every tool we build is tailored to how your business actually works — so you get automation you can trust.

Custom-Built Tools
Every business is different. We build custom Claude-powered accounting tools, dashboards, and automations that match your actual workflows — not the other way around.
Human Accuracy
AI handles the heavy lifting — categorization, reconciliation, report generation. A CPA reviews everything to make sure it's actually correct.
Systems That Grow With You
As your business evolves, your accounting should too. We update and expand your tools as your needs change — no starting over.

Everything your
finances need.

From cleaning up your books to building custom dashboards and acting as your financial right hand — we cover it all.

Custom AI Accounting

We build AI-powered accounting tools around your specific business — not a generic template. Automated categorization, custom dashboards, and smart reporting that actually makes sense for how you work.

Personal, corporate, and business tax filings done right. We find every deduction, minimize what you owe, and make sure you're fully compliant — no surprises at tax time.

05

IRS & Government Representation

Got a scary letter from the IRS? We handle audits, disputes, FinCen compliance, and notices — representing you directly so you don't have to deal with it.

06

Business Setup & Registration

Starting fresh? We handle entity selection, state and federal registration, IRS onboarding, and FinCen filing so you launch clean and stay compliant from day one.

Common Questions

You're probably
wondering...

What makes Celestia different from a regular accountant?
We don't just do your books — we build custom AI tools around how your business actually works. Think personalized dashboards, automated categorization, and smart reporting — all with a CPA making sure everything is accurate.
What is Claude, and how do you use it?
Claude is an advanced AI assistant built by Anthropic. We use it to power your custom accounting tools — from automated bookkeeping to intelligent reporting. As a Claude consultant, we also help businesses build, maintain, and scale their own AI-powered accounting systems.
How does pricing work?
We scope each engagement individually and lock in a fixed monthly fee. No hourly billing, no surprise invoices. You always know exactly what you're paying.
Do I need to know anything about accounting?
Not at all. That's literally our job. Tell us what's stressing you out and what you wish was easier — we'll handle the rest.
Do you work in English and Spanish?
Yes — full bilingual service from consultations through tax filings and ongoing support. No language barrier, ever.
What's a SEP-IRA?
It's a retirement savings account that lets self-employed folks contribute up to 25% of their net earnings — a huge tax advantage. If you work for yourself, you're probably leaving money on the table without one. We can set it up for you.
Is my data secure?
Absolutely. Every client gets a dedicated, isolated environment. End-to-end encryption, no data sharing, no mingling. Your information is yours.
