The Separation
Events go in: buys, sells, transfers and income. Positions and balanced double-entry journal entries come out. Each ERP gets a small adapter that writes those entries in its own format. The arithmetic is written and tested once.
Exact Amounts
Quantities and prices are Decimal values parsed from text, with a precision set per instrument: two places for a share, eight for bitcoin. A value with too many places is refused, not rounded. Positions are replayed from the events every time, by moving average or FIFO, so a corrected import corrects the history.
Cost That Is Honest
Units that arrive by transfer with no price count in the quantity but stay out of every cost figure, and each position shows how much of it has a cost on record. A sale splits into cash, the fee, the book cost of the units sold and the gain or loss, and an entry that does not balance is never sent.
How It Was Tested
69 tests cover the core, and 12 more run inside a real Odoo database. The Zoho Books and SAP adapters are tested against fakes of their APIs, not a live tenant. Importing the same statement twice adds nothing the second time.
A Note on the Images
The screens were redrawn from the project source code. Layouts, colours, icons and labels come from the code; names, addresses and amounts are sample data.
