You've come a long way. You're incorporated, you have your EIN, your 501(c)(3) letter is in hand, you've registered to solicit in your state, and you're keeping up with your annual 990 filing. The scaffolding is built. This month is about making sure what you've built can last.
Month 11 is the durability month. We're going to take your funding from "we made it this year" to "we'll be fine even in a bad one" — by spreading your revenue out, adding a base that arrives without an ask, and starting a cushion for the rough patches.
Why one big funding source is a quiet danger
When a nonprofit folds, it's often not because of a scandal or a bad program. Sometimes it's because the organization leaned on one thing — one big grant, one annual gala, one major donor — and that one thing went away. When your largest source is more than about a third of your budget, you don't have a funding plan, you have a single point of failure.
The fix is a diversified funding mix: several streams that each carry part of the load, so a lost grant becomes a line-item problem instead of an existential one. A common rule of thumb is simple — no single source should provide more than roughly a third of your budget. Funders tend to value this too; a diversified base is exactly what makes your organization look safe to invest in. Spend 30 minutes this month mapping every revenue source as a percentage of your total, and you'll see your risk in black and white. Our guide walks you through it: the funding mix.
The two-question gut check
Pull up last year's revenue and ask: (1) What is my single biggest source as a % of the total? (2) What happens to us if that source disappeared next year? If the honest answer to #2 is "we close," diversifying isn't optional — it's survival.
Add a base that arrives without an ask
Here's the part most founders never get to: a healthy mix isn't just more sources, it's at least one source that shows up whether or not you run a campaign. Recurring monthly donors are one. Passive funding is the other — income earned from supporters' everyday spending instead of a direct ask. A supporter takes one setup action, and then a share of money they were going to spend anyway flows to you automatically, month after month, with near-zero staff effort.
The labor doesn't repeat every time money arrives — that's the whole appeal. The catch is that not every passive program is worth promoting; a fraction-of-a-percent donation rarely adds up. The ones worth your time are recurring, low-effort, capture everyday (ideally local) spending, and return a high enough share to matter. We lay out how to tell the difference: passive fundraising explained.
Where Good Circles fits
Good Circles is one way to build that recurring, unrestricted base — and it's free for your nonprofit. It's a local-first community marketplace where supporters save about 10% as shoppers, and 10% of each merchant's net profit is directed to the cause they picked. That works out to roughly $72 per active supporter per year (an estimate) — money that recurs and has no strings attached. It launches in Mississippi first in September 2026, and early nonprofits can claim Founding status now. See how it works for nonprofits →
Start your operating reserve
The last piece of durability is a cushion. An operating reserve is unrestricted, liquid cash set aside so a late grant or a slow month doesn't force you to cut programs. You'll hear "keep three to six months of operating expenses" everywhere — treat it as a guideline, not a mandate. If you're just starting, aiming for one to three months first is a perfectly reasonable on-ramp.
Two words matter: unrestricted (you can spend it on anything) and liquid (you can reach it fast). Restricted grant money never counts. Build it slowly — open a separate account, automate a small monthly transfer from unrestricted surplus, and have your board adopt a short written reserve policy stating the target, when it can be tapped, and how it gets refilled. That policy is what auditors and funders read as a sign of real financial health. Here's the full how-to: operating reserves.
Notice how it all connects: the more diversified and recurring your income, the lower the reserve you can comfortably sit on, because cash arrives predictably. Durability compounds.
