Every module in BlossomERP keeps its own documents — invoices, receipts, payments, goods receipts — but they all write to one set of books, and Accounts is where those books live. When a sales invoice posts, its journal appears here; when a payment is made, here; when stock moves at a cost, here. Accounts is also where the finance team does its own work: the chart of accounts, manual journals, banks and reconciliation, budgets, periods, and the statements your accountant and your bank will ask for.
Two ideas run through the whole chapter. First, the ledger is kept in your company's home (functional) currency — foreign documents are converted at their frozen rates as they post (see 1.11 and 7.11), so the books always add up in one currency. Second, posted is posted: nothing here is edited after the fact; corrections travel as reversals and new documents (1.6), which is what makes the reports in this chapter safe to rely on.
Accounts is a core module — it is always on, in every company, at every workflow depth.
