Our Expertise

Three disciplines.
One integrated practice.

AdAstra's work sits at the intersection of financial infrastructure, global operations, and strategic decision-making. We don't generalize—we go deep in areas where the complexity is real and the stakes are high.

01

Financial Systems, Process & Controls

Most mid-market companies reach a point where their financial infrastructure stops keeping up. Reporting is fragmented, controls are informal, and the ERP that worked at $10M is buckling at $50M.

We diagnose the gaps and build what's actually needed—from ERP configuration and custom reporting architecture to procure-to-pay process design and internal control frameworks that hold up under audit or investor scrutiny.

ERP ImplementationProcess DesignInternal ControlsCustom ReportingP2P Optimization
02

International Expansion

Crossing a border introduces a new layer of financial complexity—entity structure, intercompany accounting, transfer pricing, multi-currency reporting, and compliance obligations that vary by jurisdiction.

We help finance teams build the infrastructure to manage international operations cleanly from day one, so that expansion doesn't create a compliance backlog or a reporting blind spot.

03

Strategic Finance Advisory

The best financial strategies aren't built in spreadsheets—they're built from a clear understanding of unit economics, cash flow dynamics, and the real levers in your business model.

We work alongside CFOs and leadership teams to build the analytical frameworks, profitability models, and cash visibility tools that support better decisions at every level of the organization.

Built for how financial professionals actually work.

Workflow 01

Build a New COA

For new clients and new engagements. An adaptive interview branches based on your answers — industry, entity type, financing structure, accounting framework, multi-entity complexity. The AI analyzes the full business profile and generates a complete, framework-specific COA ready to edit and export.

12+ industry categories with subcategories
14 financing instrument types including SAFEs, convertible notes, venture debt
Multi-entity structure support — intercompany, consolidation, management fees
Agency Mode for CPAs and fractional CFOs working on behalf of clients
Agentic AI follow-up questions before generation
Workflow 02

Audit & Fix an Existing COA

For inherited clients and messy books. Upload an existing COA as a CSV. The tool analyzes it against GAAP best practices for that specific business and returns structured findings — Critical, Warning, and Suggestion — that you can accept, modify, or dismiss. The cleaned COA exports the same day.

Critical: misclassifications that distort financial statements — auto-corrected on Accept
Warning: non-standard practices causing reporting confusion or audit exposure
Suggestion: naming conventions, missing accounts, structural refinements
Accept, Modify, or Ignore each finding individually
Export revised COA in target ERP format — same day

Built by a Practitioner

Not built by developers.
Built by someone who's done the work.

COABuilder was created by Phillip Coomes — a fractional CFO and former controller with 17 years of hands-on finance experience across climate tech, SaaS, multinational corporations, and government. He built the tool because he lived the problem.

That practitioner foundation is what makes COABuilder different. Every framework selection, every account name, every audit finding reflects real accounting judgment — not guesswork, not generic output.

Framework precision you can trust

US GAAP, IFRS, Swiss GAAP, UK FRS 102 — the output reflects genuine framework conventions, not renamed generic accounts.

Built for financial professionals

The language, the logic, and the workflows are designed for CPAs, Controllers, and Fractional CFOs and business owners alike.

A product of AdAstra CFO

COABuilder is one expression of the same expertise AdAstra brings to every client engagement. The tool is fast. The judgment behind it took 17 years to build.

The iceberg is closer
than it looks.
Let's talk.

Most companies that work with AdAstra didn't know exactly what they needed when they first reached out. They knew something was wrong — a close taking too long, a fundraise approaching with financials that weren't ready, a system that had stopped keeping up. The conversation started there. It can start the same way here.

Scaling internationally and need the infrastructure to match
