DomainBook Pro is the portfolio command center for domain brokers and investors — the modern alternative to a 40-column spreadsheet, DomainMOD or Efty. It tracks acquisition cost basis, fees and renewals paid, then computes net profit, ROI and annualized ROI on every sale. Live RDAP lookups keep expiration dates real, with color-coded 30/60/90-day countdowns and an ICS calendar feed so a good name never drops by accident. Flat $20/mo, unlimited domains, 14-day free trial.

Hey Product Hunt 👋 I build small, focused SaaS tools, and DomainBook Pro came out of a problem I kept seeing: every domain investor eventually builds a 40-column spreadsheet — and it goes stale the moment a name renews. It never tells you your real return, and sooner or later a good name quietly expires. So I built the thing the spreadsheet was pretending to be: • Every domain, every registrar, in one searchable ledger • Live RDAP lookups, so expiration dates are real rather than remembered • Cost basis in, sale out — net profit, ROI and annualized ROI calculated for you • 30/60/90-day renewal countdowns, plus a private calendar feed • Quarterly review that sorts the book into Hold / Monitor / Review / Drop • Reports and multi-tab Excel export for taxes and your accountant Flat $20/mo, unlimited domains, 14-day free trial, no credit card to start. Would love your feedback — especially from anyone running a book of names today. What's the one number your spreadsheet never gives you?

Love that you handled the spreadsheet fatigue problem head-on, the net profit calculation and ICS feed alone would save me hours each month. One thing that would really push it over the top for me is a quick CSV import so I can move over years of acquisition records from my existing Excel sheet without retyping every entry.

Love that the 30/60/90-day color-coded countdowns paired with an ICS feed actually solve the "oh no it dropped" panic that every spreadsheet jockey knows too well. Smart craft choice.
