Which Church Management Software Should You Choose?

Short answer: Pick it once, for the next decade. Under 500 people you probably do not need one; a giving tool, an email list, and spreadsheets will do. Between 500 and 2,500, look at Planning Center first, then Tithely, then Pushpay. Approaching 2,500, consider Rock RMS. Whatever you choose, the migration takes a year and half the work is people, not software.

I led Saddleback's move from a custom-built people system to Rock RMS in August 2025, alongside overhauling our content platform, email client, authentication, media platform, and data warehouse. The launch date is burned into my mind like my kids' birthdays. Everything below comes from that year.

Does our church need a church management system?

Not until roughly 500 people. Below that, most of your data lives comfortably in your giving platform, your email newsletter tool, and Google Sheets for volunteer teams. Adding a CRM early adds cost and admin without adding much you can act on.

Around 500 the math flips. You need to manage people, volunteer rosters, groups, check-in, and ideally giving in one place, and you need a system that can grow with you. That is when you choose. And you choose carefully, because you change a CRM and giving system only about once every decade.

Which church management software is best?

It depends on size and on how much you want to build versus buy.

500 to 2,500 people. Take a hard look at Planning Center and see if what they do works for your church. Tithely is my second option because of how much they bundle: giving, website, app, and people in one. Pushpay's system would be my last look. Your giving platform should then follow whatever CRM you pick, and your email should move to what the CRM provides if it has a real email client with list management.

Approaching 2,500 and beyond. This is where Rock RMS starts to make sense, and not before. Rock is free to download and self-host, with optional managed hosting, and it is the customizable powerhouse of the category. The trade is a steeper learning curve and the need for someone technical, or a partner, who can build on it. If you do not have that, Planning Center's simplicity is worth its price.

Whatever tier you are in, the deciding question is the same. Can this platform grow with us for eight to ten years? Do not pick a tool for the next few years. Most of our twelve months of work was "repiping the house," vital work that nobody will ever see, and you only want to do it once.

What does a migration actually take?

Longer than "it's just code" suggests. Here is the honest version from our switch.

Plan on a year. We had a solid six-month process leading up to launch, and it took the full twelve months before we could spin up new features quickly. Five months in, we were productive. Twelve months in, we were fast.

Change management is half the battle. Switching platforms is 50 percent technical change and 50 percent making sure your core users understand it. We have hundreds of staff and thousands of volunteers touching these tools weekly. I over-communicated early and often, honestly to the point of being a pest: monthly timetable updates, regular trainings in person and on Google Meet, and open office hours. Our motto was that no one should be shocked on launch day, and no one was. Never assume your one email blast was read. Build an on-demand training page you can point people to.

Software is slower than you think. Between ideation, building, sandbox testing, and app store approvals, a single cycle runs six to eight weeks. That means you realistically implement about six major ideas a year. Fixing one thing often breaks another. So every idea now gets vetted against one question: how does it advance the mission, and is it worth the time and cost?

You need conviction. Everyone is a user, and every user has an opinion about how the app should work. To cut through the noise you need a strong gut sense of where you are going and a phased plan for the next twelve months. When someone gives you the side-eye because their feature is not built, the honest answer is that something else will have a bigger impact first. Learn to say "not yet" instead of "no."

Can AI help run a church management system?

Yes, with a real caveat. Since moving to Rock, I have used Claude to tweak our homepage, add an engagement timeline to people's profiles so staff can see how connected someone is before following up, and build reports for forms, events, deletions, and retention. It has also helped diagnose bugs. When baptism data stopped populating, Claude flagged that a scheduled job had not run in a week. When kids' check-in numbers did not line up, it was wrong a few times and then surfaced a rule in our jobs that was causing the gap.

The caveat is that this works because I deeply understand how our data is structured and how the systems fit together. Real developers were still involved and vetted my changes, and I broke something once by adding a workflow that seemed like it should work. As Andrej Karpathy put it, you can outsource your thinking, but you cannot outsource your understanding. Be careful what data you hand to a model, and double-check that nothing you touch is a core system.

What should we actually track once the system is in?

The system exists so you can see people, not so you can count views. The reports I care about show how new people attend specific events and take key next steps, how engaged a person is before a staff member follows up, and where people fall out of your process. Be skeptical of raw viewer data everywhere, including your own stream. The back door matters more than the front door, and a good people system is how you finally see the back door.
