Kachink is a finance tracker that lives inside Claude. Log invoices, track project expenses, and handle multi-currency payments — without leaving your workflow.
Most freelancers use four or five different tools to track what they earn and spend. Kachink collapses that into one conversation.
Clients pay in EUR, GBP, USD. Manually converting and recording each invoice wastes time and introduces errors.
Software subscriptions, travel, home office costs — they slip through the cracks when tracking is inconvenient.
Reconstructing a year of expenses from bank statements and email receipts takes hours. Or days.
You're already in Claude writing proposals, summarizing contracts, and managing projects. Kachink adds finance tracking to that same conversation.
Tell Claude about an invoice the same way you'd tell a colleague. Currency conversion is automatic.
Log software tools, travel, client dinners, and equipment as you spend. Categories are assigned automatically.
Ask Claude for a breakdown by category, date range, or keyword. Copy it straight into your accountant's spreadsheet.
This is what using Kachink actually looks like — no menus, no forms.
Log in any currency. Live exchange rates convert every payment to your base currency at log time — no mental math.
Set up monthly retainers and subscriptions once. Auto-logged on the right day every month — no action needed.
Expenses are automatically categorized into Software, Travel, Food, Utilities, and more — ready for tax time.
Open an interactive dashboard inside Claude chat showing totals, category breakdown, and transaction history.
Your data lives in an isolated Cloudflare database. Google OAuth authentication. Nothing shared.
Ask anything: "show travel last quarter", "how much did I earn in March", "delete that last entry".
Open Claude's settings, add a custom MCP integration, paste the server URL, and authenticate with Google. Your first transaction takes less than 10 words.
