Spreadsheet vs. Domain Portfolio Software: An Honest Comparison
Forget the SaaS tools for a moment — the real incumbent in domain portfolio management is a spreadsheet. Most investors run one, and most portfolio software is really competing with Google Sheets, not with each other.
So this comparison takes the spreadsheet seriously first, because it deserves it, and then is precise about where it fails — which is not where most tool marketing claims.
The steelman: why the spreadsheet is genuinely good
It has no subscription cost. It is infinitely flexible: your columns, your formulas, your weird color-coding system that only you understand. It is yours, so no vendor can sunset it, paywall it, or leak it. It works offline, exports to anything, and doubles as the CSV you will eventually hand to your accountant.
For a portfolio under about 25 domains at a single registrar, updated by a disciplined owner, a spreadsheet is not a compromise. It is a reasonable system.
Where the spreadsheet silently fails
Every failure mode has the same shape: the spreadsheet records what you typed, not what is true, and it never volunteers anything.
- •Stale expiry dates: the registry's date moves — a transfer adds a year, a renewal shifts it — and your cell does not. The authoritative date lives in RDAP, not in row 14.
- •No alerts: a spreadsheet cannot email you 30 days before a renewal. The whole system depends on you remembering to open it.
- •No registry verification: typos and copy-paste errors look identical to correct data, and nothing ever cross-checks them.
- •Update decay: the sheet is perfect the week you build it and drifts every week after. Multi-registrar portfolios decay fastest.
- •Fragile P&L: renewals quietly accumulate as untracked cost basis unless you log every charge by hand, so your profit number flatters you.
Side by side
| Spreadsheet | Portfolio software | |
|---|---|---|
| Cost | Free | Trials are common; paid from ~$5-20/mo |
| Expiry dates | Whatever you typed, whenever you typed it | Re-verified against the registry (RDAP) |
| Renewal alerts | None — you must remember to look | Alert ladder emails you at set intervals |
| Multi-registrar view | Manual consolidation | Automatic, one portfolio |
| Cost basis and P&L | Possible with sustained discipline | Accumulates as you record events |
| Flexibility | Unlimited | Whatever the tool models |
| Failure mode | Silent staleness | Vendor risk, subscription cost |
When the spreadsheet is the right choice
Keep the spreadsheet if your portfolio is small and single-registrar, you genuinely update it, and auto-renew is on with a current card. Keep it too if your tracking needs are so idiosyncratic that no tool's data model fits — flexibility is the one axis where the spreadsheet cannot be beaten.
How Sourdough splits the difference
Sourdough is built for spreadsheet defectors: import your existing sheet via CSV and every domain gets re-verified against the registry with live RDAP/WHOIS and DNS data, then kept current — with a renewal alert ladder, lifecycle stages, cost basis, and P&L on top. A 7-day free trial with $0 due today, so the switch costs nothing to test. And your data exports back out; no lock-in is part of the pitch.
Frequently Asked Questions
Is a spreadsheet good enough for managing domains?
Up to roughly 25 domains at one registrar, with auto-renew on and a disciplined owner — yes. Past that, or across multiple registrars, staleness and the absence of alerts start creating real risk of missed renewals and fictional P&L.
What should a domain portfolio spreadsheet include?
At minimum: domain, registrar, registration and expiry dates, auto-renew status, renewal cost, acquisition cost, lifecycle status, and sale info. We publish a free template with these columns — see the cross-link on this page.
Can portfolio software import my existing spreadsheet?
Generally yes, via CSV — Sourdough does. A good import re-verifies expiry dates and registrar data from the registry rather than trusting the sheet, so years of drift get corrected on day one.
