Statement of Account

theluckystrike/mcp-statement-of-account

Client statements of account built from a local invoice, credit-note and deposit ledger: opening balance, every invoice, payment and credit note in date order, closing balance, and receivables aged into 0-30, 31-60, 61-90 and 90+ day buckets as at any chosen date, so a historic aging is not silently emptied by payments that arrived later. Exports plain text or an A4 PDF and drafts a friendly, firm or final payment chaser. Nothing is written back to the source ledgers.
