Domain Portfolio Management

A domain portfolio is an asset portfolio, and it deserves the same discipline: know what you own, what each name costs to hold, when every renewal hits, and what you would sell for. Most investors run this on memory and a spreadsheet — until a missed renewal or a forgotten transfer lock costs them a domain worth more than years of tooling.

These guides cover the operational side of domain investing that rarely gets written down: tracking expiration dates across registrars, deciding which names to drop, keeping records that survive tax season, and knowing your real profit and loss instead of a gut feeling.

They pair with Sourdough, our portfolio manager that enriches every domain with live RDAP/WHOIS data — but every guide works even if you never leave your spreadsheet.

Track Expiration Dates
Registrar auto-renew fails more often than you think. How to track domain expiration dates across registrars with RDAP, calendars, and renewal ladders.
Renewal Strategy
How to decide which domains deserve another year, when multi-year renewals make sense, and how to catch renewal price drift before it eats your margin.
Multiple Registrars
Domains scattered across registrars is normal — losing track of them is not. How to build one source of truth for expiry dates, costs, and security.
Spreadsheet Template
The columns a domain portfolio spreadsheet actually needs — name, registrar, expiry, cost basis, renewal cost, status — and where spreadsheets break down.
ROI & P&L
How to compute real domain portfolio P&L: full cost basis, renewal drag, realized vs unrealized gains, and sell-through rate — not a gut feeling.
Records & Taxes
The records domain investors should keep all year — acquisitions, renewals as carrying costs, sale proceeds and fees — so tax season is a report, not a dig.
When to Drop
A framework for the drop decision: renewal cost vs realistic value, escaping sunk cost, and an annual pruning pass that keeps renewal drag from compounding.
Managing 100+ Domains
Past 100 domains, per-name management dies. Bulk operations, naming conventions, a fixed review cadence, and automation that keeps a big portfolio honest.
Domain Lifecycle
Every stage a domain moves through — registration, active life, expiry, grace, redemption, pendingDelete, and the drop — and what you can still do at each.
Domain Watchlist
How to track domains you want but don't own: watching expiry dates and status changes, when to backorder, and the basics of catching names at the drop.
Portfolio Valuation
Portfolio valuation that survives contact with a buyer: comparable sales, appraisal tools in their place, tiering, and the liquidity discount nobody applies.
Audit Checklist
A once-a-year audit that catches silent portfolio rot: ownership details, contact emails, locks, expiry dates vs the registry, renewal prices, and DNS.
Selling Domains
Where portfolio domains actually sell — marketplaces, landers, outbound — plus BIN vs make-offer pricing and how to handle inbound inquiries without leaks.
Security & Locks
Domain theft rarely attacks the registry — it attacks your inbox. Transfer locks, registry lock, 2FA, and securing the email account that controls it all.
Diversification
TLD bets, category fashion, and tier concentration — plus renewal-cost weighting: why a portfolio's risk lives in what it costs to hold, not just its count.

Frequently Asked Questions

What is domain portfolio management?

Domain portfolio management is the practice of tracking every domain you own as a financial asset: its registrar, renewal date and cost, acquisition price, lifecycle stage, sale listings, and inbound offers. The goal is simple — never lose a name by accident, never renew a name you meant to drop, and know your real return.

Do I need software to manage my domains?

Under about 25 domains at a single registrar, the registrar dashboard plus a spreadsheet can work. Past that — or the moment you hold names at two or more registrars — manual tracking starts failing silently: renewal prices drift, expiry dates change after transfers, and spreadsheets go stale the day you stop updating them. Dedicated tools pull live registry data instead.

How is Sourdough different from my registrar dashboard?

A registrar dashboard only shows the domains held at that registrar, and it shows the registrar’s view. Sourdough sits above all your registrars: one portfolio with live RDAP enrichment, renewal forecasting, cost basis and P&L per domain, sale listings, and inbound offer tracking. It starts with a 7-day free trial, then $10/mo.
