A spreadsheet is fine, until the maths breaks.

An honest take from someone who builds alumni software for a living: most schools should stay on a spreadsheet longer than they think. Switching too early is a real cost — and switching too late is one that almost never shows up on an invoice. Here's the line that actually marks the difference.

If you run an alumni program out of a spreadsheet today, the conventional wisdom is that you're behind. Software vendors will tell you this. So will alumni-engagement consultants. So will, occasionally, your own IT department.

I think the conventional wisdom is mostly wrong.

A spreadsheet is free. It's flexible. Every member of your team already knows how to use it. For a school with a small alumni community and a clear handful of moments to coordinate each year, a spreadsheet does the job. There's no shame in being on one, and no virtue in upgrading prematurely.

The honest question isn't "are you on a spreadsheet?" It's "are you past the line where it stops working?" That's a more interesting question, because it has a real answer.

The three signals that mark the line

From watching hundreds of schools move from spreadsheets to platforms — and watching others stay on spreadsheets longer than expected, often happily — three signals consistently show up at the inflection point. None of them is decisive on its own. Two or more being true at the same time is usually the moment to start looking seriously.

1 You've crossed roughly 500 alumni records

Below this number, a spreadsheet stays navigable. You can scroll the whole thing, you can spot duplicates by eye, and search-and-filter does what you need. Above it, things start failing in subtle ways. Search returns results slowly enough that you stop using it. Filters get complex enough that you save them in a tab you forget about. Records get duplicated and the duplicates aren't caught until somebody gets the same reunion invite twice. None of these are dramatic failures — they're slow leaks. The cost compounds, usually right before a reunion when you need the spreadsheet to be at its best.

2 You're trying to run more than one event a year

A single annual event can be managed in a tab. Two events, especially if they overlap, are where the spreadsheet starts losing track. Who's been invited to which one. Who's RSVP'd to which. Who paid for which. Which seating list belongs to which event. The cost of getting this wrong is real — the alumna who turned up to the wrong event because someone got the date right but the venue wrong remembers it for years. A platform handles this without you thinking about it; a spreadsheet handles it only as well as the person updating it remembers to handle it.

3 You're spending more than an hour a week on the data itself

Not running events. Not writing communications. Just maintaining the data — chasing bounces, updating fields, merging records, fixing typos, deduplicating. Below an hour, the spreadsheet is paying for itself in saved subscription fees. Above an hour, you're paying for it in opportunity cost. That hour was supposed to go into the work that grows the community, not the work that maintains the list.

Two of three being true is the signal. None of them on their own is decisive. The cost of switching too early is real. The cost of switching too late almost never shows up on an invoice.

What gets missed on a spreadsheet that's past the line

Here's where the honest case for switching does get strong, but it isn't usually the case schools think.

The headline cost of staying on a spreadsheet past the inflection point isn't the time. It's the work that doesn't get done because the time is going somewhere else.

The 52 hours a year of data maintenance, valued at typical school admin staff costs, sits around the price of an entry-level platform subscription. So on time alone, the maths is closer to a wash than people expect.

What tips the maths isn't the time. It's what those 52 hours were supposed to be for.

A reunion that didn't quite fill the room because the invite list missed people you couldn't easily segment. A donor who never got thanked because the donation record sat in a separate tab. A scholarship cohort that nobody knew was due for a five-year follow-up. An alumnus who was clearly willing to mentor a student, but the question never got asked because finding the right alumnus took too long. These are not theoretical costs. They're real, they accumulate, and they almost never appear as a line item on anyone's report.

A counterintuitive piece of advice

This will surprise people who expect a SaaS founder to argue otherwise: the cost of switching to a platform too early is also real.

A platform you outgrow your team's capacity to use is worse than a spreadsheet. An expensive piece of software that gets used by one person who quits is worse than a spreadsheet that anyone can pick up. A switching project that takes six months and exhausts the person running it can leave the alumni program weaker than it was before.

The schools that have moved most successfully are the ones who waited until they had clear evidence the spreadsheet was failing them, then moved decisively. The schools that have moved least successfully tended to upgrade because someone told them they should, before the spreadsheet was actually broken.

A useful test

If a member of your team was off sick for a month, would the alumni program function? On a spreadsheet, this is often the most honest stress test — it surfaces the dependencies on a specific person's knowledge of the file. If the answer is no, that's a signal worth taking seriously regardless of headcount or budget.

The decision worth pausing on

If two of the three signals above are true for your school today, it's probably time to start looking. Not because someone said you should, but because the maths is telling you. If one signal is true, it's worth keeping an eye on. If none are true, stay on the spreadsheet. It's working.

The cost of switching too late is invisible until it isn't. Quietly thinner reunions. Donors who never got thanked properly. Scholarships nobody knew about. The day the spreadsheet's main owner leaves and nobody else knows how the colour-coding works.

The cost of switching too early is visible immediately — software that gets paid for and underused, a transition that takes longer than expected, momentum lost while everyone learns the new tool.

Neither cost is hypothetical. Which one your school risks running into depends on where you are on the curve. The first job is to know which one is closer.

What's your rule for knowing it's time?
