Grounded in

IRS Publication 1771 — charitable contributions

The substantiation rules for what an acknowledgement must legally contain. A warm letter that omits the required wording is a problem, not a nicety.

* About that monthly figure

It is an estimate at the scale one student reaches, not a quote. Before anything goes live, week three sets a ceiling:

  • A hard spending cap on every provider account, set before the project goes live.
  • A billing alert at half the cap, so nothing is a surprise.
  • Free tiers first: every project in this list is designed to sit inside one at student scale.
  • A kill switch: how to take the project offline in one step if the numbers move.
