Sovereign Services · Made in New ZealandYour Ledger. Your Machine. Your Control.
AES-LedgerPro is a locally hosted, single-tenant, encrypted business management system. Double-entry accounting, multi-region payroll (NZ, AU, US, UK), inventory, POS, and job costing running entirely on hardware you own — with zero vendor-hosted servers.
No Cloud. No Multi-Tenant Databases. No Vendor Telemetry.
"Your ledger lives on your machine — encrypted with your password."
Everything Your Business Runs On. One Single Install.
Say goodbye to stitching together five distinct SaaS subscriptions. AES-LedgerPro consolidates double-entry accounting, payroll, inventory, till operations, and worksite scheduling onto a unified local ledger.
Double-Entry General Ledger
Mathematical Balancing & Audit Trail
Strict double-entry accounting backbone with automated balance sheet, multi-period P&L, trial balance, and a tamper-evident SHA-256 append-only cryptographic hash chain on every posting.
Basilica Multi-Region Payroll
NZ, Australia, United States, United Kingdom
Autonomous local payroll engines for NZ (PAYE, KiwiSaver, WINZ abatement), AU (PAYG, Super, BAS), US (Federal, State, 1099-NEC), and UK (PAYE, NI, Auto-Enrolment, CIS, VAT).
Multi-Warehouse Inventory & FIFO
Ledger-Integrated Cost Accounting
Cost-of-goods-sold calculation via FIFO or weighted-average costing, bills of materials / manufacturing assemblies, barcode scanning, and multi-location warehouse P&L reporting.
Point of Sale & Hospitality
Quick-Sale & Table Service Floors
Counter quick-sale register with live barcode camera scanning, thermal receipt printing, table layouts, split bills, and gift card redemption tracked directly against balance sheet liabilities.
Job Costing & Worksite Mapping
Interactive OpenStreetMap Integration
Track physical work, employee time allocations, and materials consumed per job site. Map sites via Leaflet/OpenStreetMap with zero external third-party API keys or telemetry.
Citadel Zero-Trust Remote Relay
Outbound-Only Private Firestore
Zero open inbound firewall ports. Remote client devices connect through client-owned Firestore keys ('Bring Your Own Key') and require cryptographic pre-authorization in the Device Manager.
The Basilica Tax & Payroll Engine
Rather than treating international taxes as an afterthought, AES-LedgerPro features discrete, deep tax computational models for New Zealand, Australia, the United States, and the United Kingdom.
New Zealand Native Compliance
IRD Direct AlignmentFull GST return preparation, PAYE withholding schedules, KiwiSaver employer/employee contributions, Student Loan repayment tiers, and parental leave planning.
WINZ Entitlement & Abatement
Private employee-controlled planner forecasting wage impacts on benefit thresholds.
Akahu Direct Bank Feed
Automated local bank line retrieval with zero cloud intermediary credential exposure.
Multi-Currency VAT / GST Return Simulator
Add sales and purchase lines in any currency, set the FX rate to the region's home currency, and watch the official Inland Revenue (IRD) return boxes recompute in real time — exactly what the Basilica engine prepares from posted ledger activity. All math runs locally in your browser.
GST-inclusive · fraction 3/23 (15/115). Foreign-currency lines convert at the FX rate you set, then the region's tax fraction applies. This mirrors how Basilica prepares each return straight from posted ledger activity — no spreadsheet stitching.
Inspect the Hash Chain in Real Time
Every ledger posting is sealed into a SHA-256 append-only hash chain — the same tamper-evident audit trail AES-LedgerPro verifies from inside the app. Edit any posting below to watch the chain break, then re-seal it yourself. All hashing runs locally in your browser.

Append a new posting
Note the dual guarantee: the trial balance stays balanced even after tampering — structural correctness alone cannot detect a modified figure. Only the SHA-256 hash chain exposes it. This is exactly why AES-LedgerPro seals every posting.

Cryptographic Privacy Stated as Law.
We believe your general ledger is your company's most sensitive operational artifact. It should never sit unencrypted on a vendor's multi-tenant server, vulnerable to subpoenas, scraping, or unannounced subscription price hikes.
