SEOSiri CapEx Engine: The World's First Sovereign, Browser-Based Capital Expenditure Intelligence Platform for MNCs
Every quarter, finance teams across the world face the same problem: they need to make capital expenditure decisions worth millions — and their best available tool is a spreadsheet that breaks the moment two people open it simultaneously.
Bloomberg terminals cost $24,000 per year. Big Four advisory engagements cost more. And both require you to send your most sensitive financial projections — your WACC assumptions, your PPE valuations, your five-year cash flow forecasts — to servers you do not control.
That gap is now closed.
Introducing the SEOSiri Sovereign CapEx Engine
The SEOSiri Efficiency & CapEx Engine is the world's first browser-based, sovereign capital expenditure intelligence platform built to institutional financial standards. It runs entirely inside your browser — computing NPV, IRR, IFRS depreciation, ESG analysis, and real-time FX conversion — without sending a single number to an external server.
What "Sovereign" Means
Sovereign means your data belongs to you — completely. Every calculation runs locally in your browser via JavaScript. Your PPE values, WACC, and cash flow projections never leave your device. No cookies. No analytics SDKs. No user accounts. Open your browser's DevTools (F12 → Network) during a calculation — you will see zero financial data transmitted.
- All NPV, IRR, depreciation, ESG math — local JavaScript
- Form data stored in browser localStorage only — you can clear it any time
- Optional backend (api.seosiri.com) for audit-trail stamping only — called silently after results already display
- Works 100% offline if the backend is unavailable
The Mathematics: CFA Institute Precision
This is not a rough estimator. The engine implements institutional-grade algorithms used by CFA Institute, Bloomberg, and Big Four advisory firms:
| Metric | Algorithm | Standard |
|---|---|---|
| CapEx | (End PPE − Begin PPE) + Depreciation | IAS 16 / ASC 360 |
| NPV | Σ[CFₜ/(1+r)ᵗ] − C₀ − Carbon Liability | DCF + TCFD ESG Adjustment |
| IRR | Secant Method, tol = 1×10⁻⁹ | CFA Institute Standard |
| Depreciation | SLM / DDB / SYD (selectable) | IAS 16.62(a) & (b) |
| ESG Penalty | 2% × CapEx (shadow carbon rate) | TCFD Recommendation |
Four Institutional Modules That Close the Industry Gap
Module 1 — Business Group Aggregator (CFO Portfolio View)
Select from 9 industry groups — Logistics, Technology, Infrastructure, Energy, Financial Services, Healthcare, Retail, Manufacturing, or Custom — and specify the legal entity within the group. After each execution, the Business Group Aggregator shows company-wide CapEx and NPV exposure per group across all sessions. This gives the Group CFO a consolidated portfolio view without an ERP query.
Module 2 — Expenditure Category Tagging (IFRS Tax Treatment)
16 expenditure categories across 4 groups (Technology, Facilities, Operations, Strategic). Each category surfaces the applicable IFRS/GAAP tax treatment guidance inline — IAS 38 for software, IAS 23 for construction borrowing costs, IFRS 16 for lease right-of-use assets, TCFD guidance for green assets. This prevents the most common CapEx governance error: miscategorising expenditure with different amortisation implications.
Module 3 — Project Pipeline Tracker (ISO 55001)
A 6-stage visual pipeline (Idea → Proposal → Budget → Approval → Execution → Audit) advances automatically based on your strategic alignment score and coverage ratio. This is not decorative — it provides the stage-gate audit trail required by ISO 55001 asset management standard and satisfies the auditability requirements of most MNC investment policy statements.
Module 4 — FX Engine (Real-Time Currency Conversion)
Live exchange rates from an open CORS-safe API convert your CapEx figure into USD, EUR, BDT (Bangladeshi Taka), GBP, and JPY simultaneously. Refreshes every 5 minutes. For multinational treasury teams managing cross-border capital allocation, this eliminates the manual conversion step that introduces foreign exchange risk confusion into board presentations.
