Foundation
What a business event is, why every one of them has two sides, and how debit and credit stop being vocabulary and start being a tool. No prior accounting assumed.
A library, a course path and practice tools for anyone who wants to understand financial and business concepts properly — from the first journal entry to consolidated reporting. The interface and guidance are available in English, German, Persian and Arabic; each long-form shelf states the editorial editions currently available.
The path is ordered, but it is not a queue. Come in where the material stops being obvious.
What a business event is, why every one of them has two sides, and how debit and credit stop being vocabulary and start being a tool. No prior accounting assumed.
The working year: period closing, inventory and cost, receivables and payables, payroll, VAT and the reports a manager actually reads.
Treasury and multi-currency, project and contract finance, valuation, group structures and consolidated reporting — with the judgement calls stated as judgement calls.
A hundred curriculum chapters and fifty research articles, searched by what they say rather than by what they are called.
The curriculum itself. A hundred chapters written from the ground up rather than assembled from summaries, ordered into ten tracks that run from a household budget to consolidated reporting and the markets. Open any chapter to see the question it answers and the concepts it defines.
Edition 2026.1, reviewed through 31 August 2026. Written in English and Persian, aligned chapter for chapter; the Arabic and German editions are being written.

Fifty subjects that are moving right now — the 2026 economy, digital money, AI in commerce and accounting, and the reporting rules that changed this year — each researched against official sources and written for the decision it actually affects.
Double-entry, the chart of accounts, the trial balance and the three statements, explained without jargon and worked through on real documents.
Pricing, margin, working capital, budgeting, and the small number of ratios that tell you whether a month went well.
Purchasing, inventory, distribution, import and export documentation, incoterms, customs and landed cost.
How VAT, withholding and payroll obligations work in general, and what changes in the United States, Canada, the United Arab Emirates and Iran.
Foreign exchange, metals, commodities and interest — what moves them, and how a movement reaches your costs and your treasury.
The same concepts shown inside the platform: where each one is posted, which report it lands in, and what Varza Ⅰ can do with it.
Reading explains a concept. Posting one badly is what teaches it.
A business event in words; you post it. The trainer marks the entry, shows the correct one and explains the difference between them.
Walk a set of transactions through to a trial balance and the three statements, one posting at a time, and watch each figure move.
Change one number in a worked set of accounts and see which ratios move, by how much, and what a lender or an investor would read into it.
Every term in English, German, Persian and Arabic with the local usage rather than a literal translation — the word you would actually defend the numbers with.
If you have never posted an entry, start at the foundation and work through it in order. If you already close a month, the practitioner track will tell you quickly whether the habits you have are the ones you want to keep.
Create a workspace, import a chart of accounts and post a document. The ledger underneath is the same one that will carry you at ten times the size.
