Senior expertise, directly engaged

You work with the principal—not a junior associate handed your file after the pitch.

→

Deep before broad

We take time to understand your operations before proposing anything. Surface-level fixes aren't our style.

→

Built around your stage

Whether scaling domestically or expanding internationally, our engagements fit where you actually are.

→

Outcomes over hours

We're measured by what changes in your business—not by how many reports we produce.

How We Engage

From first conversation
to lasting infrastructure.

01

Free Assessment

An honest conversation about your business, your numbers, and where the real friction is. No pitch, no agenda.

02

Scoped Engagement

We define a clear, time-bound engagement—recurring advisory, a systems build, or a strategic project—with transparent pricing.

03

Deep Diagnostic

We go into your operations, your data, and your workflows. Three months minimum. Long enough to actually solve the problem.

04

Deliver & Sustain

Real deliverables your team can own—systems, models, frameworks—built to outlast the engagement.

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.

Two Core Workflows

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.
