1portfolio is a professional-grade book of record for serious investors: multi-currency holdings, true time-weighted returns, performance fees with high watermarks and hurdles, and reporting you can hand to an accountant.

Replace the web of spreadsheets with one accurate, always-current system — without giving up the conventions your books already follow.
Personal accounts, family funds and managed mandates side by side — each with its own reporting currency, brokers, and access rules.
Upload monthly statements from Interactive Brokers, RHB or Phillip POEMS. Trades, dividends, fees and FX are parsed, checked for duplicates, and committed only after your review.
Time-weighted returns computed month by month with capital flows handled properly, compared against KLCI, STI, the S&P and more.
High watermarks, hurdle rates, unit-price or value conventions, one-off adjustments — per year, per fund, matching how your fee arrangements really work.
Holdings, realized gains, dividends, forex, cash flow and capital statements — on screen or as a full Excel workbook, in local and reporting currency.
Give a partner view-only access, an accountant the full workbook, a co-manager edit rights — every portfolio stays private to its owner.
