Accounting and ledgers
Double-entry general ledger, a proper chart of accounts, cost centres, and the financial statements that fall out of them: income statement, balance sheet, and comparatives. The engine that everything else posts into.
Now in beta
A Windows-native ERP and accounting platform, built for South African business.
Run your whole business on your own machine. Fast, because it is not a browser tab. POPIA-friendly, because your books never leave your control. And yours to keep, in a single file you own. No lock-in, no rented access to your own data.

Lumarix keeps the whole ledger on your machine in a single file. Open it, work, close it. There is no server to babysit and no subscription holding your data hostage. It is the way desktop accounting should feel in 2026, just faster and friendlier.
Lumarix is already a working ERP and accounting engine. Here is what runs in the beta today, described honestly.
Double-entry general ledger, a proper chart of accounts, cost centres, and the financial statements that fall out of them: income statement, balance sheet, and comparatives. The engine that everything else posts into.
Quotes, sales orders, invoices, and credit notes, with customer statements and credit control. Recurring and emailed documents included.
Stock items, goods received, purchase orders, and bills, with editable landed cost and purchase price variance handled the way an accountant expects.
Run employees, earnings, and deductions through to payslips, with the figures posting straight into the ledger. No double capture.
Trade in more than the rand. Foreign-currency customers, suppliers, and documents with exchange differences accounted for cleanly.
VAT tracked on every transaction with reports you can reconcile against. Built so your numbers are SARS-ready, with e-filing on the roadmap below.
Lumarix runs at the speed of your machine, not your connection. Big ledgers open instantly and reports do not spin. No loading tab, no round trip to a server.
Load-shedding, a flaky tower, a dead router. None of it stops you invoicing or capturing. Lumarix keeps working offline because it lives on your desk, not in the cloud.
Everything lives in a single .lmx file you own. Back it up, move it, hand it over. There is no account to lock, no export fee, and nobody else holding the keys.
Because your financial and personal data never leaves your control, you are not trusting a third party with it. That makes Lumarix a calmer fit for POPIA out of the box.
These are not in the beta yet. They are what we are building toward, in roughly this order. We will only mark them done when they really are.
Submit VAT and returns straight from Lumarix, once the integration is approved and tested. The reporting is already built to support it.
Pull transactions automatically and reconcile in a click, instead of importing statements by hand.
Our accounting research product, Veritas, will bring practical AI help into Lumarix. Veritas is in research today, not shipping.
A lightweight phone app to capture, approve, and check the numbers while you are away from the desk.
A native Mac build, once the Windows release has settled. Lumarix is Windows-only for now.
The beta is invite-based while we polish the last details. Leave your email and we will reach out to get you set up. You deal direct with the engineer building it, no sales layer in between.
