Ekwo

Ekwo keeps a company's books — double-entry, in a Postgres database the company owns — and this connector lets Claude work in them as the signed-in user. What Claude can do with it Read: companies, chart of accounts, contacts, products, invoices and the ledger entries they produced, bank accounts and statement lines, trial balance, general ledger, aged balance, financial statements on the country's own scheme, VAT return boxes, EC sales list, fixed-asset register and depreciation schedules, budgets and variances, the audit trail, and the filing calendar of every company you keep. Write, drafts first: create contacts, products and draft invoices, credit notes and quotes; post a document; record and match payments; import bank statements (CAMT.053, CODA, CFONB120); take over books from another system (FEC, Odoo, Xero, QuickBooks Online, Pennylane, Sage 50, Exact Online…) after a dry run; run depreciation; close or reopen a financial year; lock periods. How it behaves A posted entry is never edited: an invoice is undone by cancel_document and an entry by reverse_entry, and the tool says which way it went. Every refusal is named (period_locked, entry_unbalanced, document_total_mismatch…) so Claude reports it instead of working around it. Rules that depend on a country live in data — country packs for more than 100 countries — never in the tools: no default country, currency or language. Row level security applies: Claude sees and changes exactly what the signed-in user may, and nothing else. Ekwo OS is open source (AGPL-3.0) and installs on any Supabase project; Ekwo Cloud hosts it for you. Connect with your Ekwo Cloud account.
