Overflow is an online giving platform for churches and nonprofits that helps you accept cash, stock, crypto, and DAF gifts in one unified church giving platform, with analytics, migration support, and donor help built in.
Both. You can be billed monthly or annually, and annual billing typically comes with a discount. If cash flow makes monthly the easier lift for your church, that is a perfectly normal way to start.
Growth and enterprise-level churches have a one-time implementation fee, which reflects the additional scope involved: multi-campus configuration, larger data migrations, deeper integration work, and dedicated hands-on onboarding. That fee is quoted up front as part of your proposal, never added later.
Yes. Overflow's Information Security Program follows the criteria set by the SOC 2 Framework, and we undergo independent third-party assessments and penetration testing of our security and compliance controls. In practice that means:
- All data is hosted on Amazon Web Services and stored on databases located in the United States.
- Sensitive information such as financial data is encrypted at rest, and all applications encrypt in transit with TLS/SSL.
- Access to sensitive systems follows least-privilege principles, with single sign-on, two-factor authentication, and quarterly access reviews.
- Every team member passes a background check, signs a confidentiality agreement, and completes security awareness training.
- Backup and disaster recovery run through our hosting provider, with monitoring and a documented incident response process behind it.
- Overflow never has access to or stores your donors' brokerage account credentials.
Full details on all of the above on Overflow's Security Page.
Admin users are included in your subscription. Multi-campus organizations are priced at the organization level rather than per site, with campaign-level reporting and fund mapping built in.
The redesigned reporting home page takes reporting to a new level of ease and efficiency. With a seamless interface, you can quickly switch between pre-configured and custom reports, providing immediate access to the most vital financial insights. Whether you’re reviewing overall donations or drilling down into specific trends, the new dashboard simplifies the process of extracting and analyzing the data that matters most to your organization.

Overflow explored App Clips very quickly after Apple’s announcement of the feature, but ultimately chose not to support them because they introduce friction for guests and limit what churches can do with Tap. Our goal is to ensure the simplest, most flexible, cross-platform tap experience for every person in the room - without exceptions.
Here are the core reasons:
1. App Clips create a split experience between iOS and Android
App Clips are an Apple-only technology.
If Tap relied on App Clips:
• iPhone users would see one experience
• Android users would be routed somewhere else entirely
This instantly breaks the unified, predictable moment churches want - especially during worship, giving, or guest connection.
Overflow Tap was intentionally built to be platform-agnostic, ensuring every person, on every device, gets the same simple, instant pathway.
2. App Clips limit the ability to redirect dynamically
A key benefit of Overflow Tap is the ability to change your destination URL in real time - even mid-service.
App Clips, however:
• Do not support dynamic redirect logic
• Do not allow you to instantly point an NFC tag to a changing link
• Require a fixed App Clip experience that can’t adapt on the fly
Churches need flexibility: a giving moment in worship, a QR replacement during announcements, a guest form for a special Sunday.
App Clips simply can’t support that level of agility.
3. App Clips constrain the kinds of content and flows churches can use
App Clips
• Restrict what you can show on screen
• Limit customization
• Don’t support rich, multi-step, or branded experiences
• Cannot deliver the same flexibility as a standard Overflow dynamic link
Overflow Tap is built to support any ministry moment, not a narrow App Clip template.
4. App Clips introduce friction - especially for first-time guests
One of the most important design goals for Overflow Tap is zero hesitation.
App Clips can:
• Ask for permission modals
• Take longer to load
• Present an unfamiliar Apple UI shell
• Feel more like an app download than a simple next step
In worship moments, that hesitation matters. Overflow chose the experience where the fewest things can go wrong - and the most people can participate.
5. App Clips cannot interact cleanly with ProPresenter flows
Many churches integrate Overflow Tap into their service flow using ProPresenter.
Because App Clips are controlled by iOS and can’t be influenced by external systems, they can:
• Interrupt service-driven transitions
• Fail to open consistently from ProPresenter’s controlled environment
• Break synchronization between the screen moment and the tap moment
Dynamic URLs from Overflow, by contrast, always work, regardless of device, OS, or display environment.
6. Overflow Tap is built for ministry use cases that App Clips weren’t designed for
App Clips work best for:
• Micro product demos
• Small app previews
• Simple one-off utilities
They were not built for:
• Generosity workflows
• Conversion tracking
• Cross-platform guest pathways
• Multi-use ministry moments
• Instant link changes
Overflow Tap needs to serve giving, next steps, registrations, guest connection, and more. App Clips cannot support that mission.
Why Overflow Doesn’t Use App Clips
In short:
• They only work on iOS
• They cannot support dynamic redirection
• They limit customization and future flexibility
• They introduce friction into spiritual moments
• They don’t play well with ProPresenter
• They weren’t designed for generosity or next-step engagement
Overflow Tap was built to ensure that everyone can take a next step instantly, no app download, no delays, no surprises.
It’s the simplest path for people - and the most flexible tool for churches.
Overflow Tap is priced and purchased at shop.overflow.co, where you can see hardware options, build your order, and get pricing for the quantity you need. Tap includes a software subscription alongside the hardware, and the shop walks you through both.
Your church can accept credit and debit, ACH, Apple Pay and Google Pay, as well as stock, crypto, Donor Advised Fund (DAF) grants, and RoundUps™. All of these flow into one online giving platform for churches so reporting stays simple.
Tap is at its most powerful paired with the Overflow giving platform. Run both and every gift lands in one dashboard, so you can see exactly which donations were sourced from a Tap, what they totaled, and how giving in the room stacks up against giving online. That is visibility most churches have never had. Launching together also means one supported rollout: a single migration, one round of team training, and one announcement to your church instead of two.
Cryptocurrencies that are compliant and accepted within the United States are available to give through Overflow's crypto donation processing platform. Please refer to The Giving Block website for an up-to-date list of supported cryptocurrencies. If you are interested in giving a coin that you don't see supported, please email support@overflow.co. It is sometimes possible to facilitate your donation off-platform depending on the type of coin and gift value
Yes. Fee coverage is an optional setting your church turns on in the dashboard. When it is enabled, donors are offered the choice to cover the processing fee on their gift at checkout. It is the church's call whether to offer it at all, and the donor's call whether to accept, so nobody is forced into it.
