The Problem

The "rat's nest" is costing you more than you think.

You added a tool for this department, another for that process, and another because someone needed one feature. Now you're a dozen systems deep — paying more than you should, with less efficiency than you need.

Need a report? Ask Betty. Then ask June. Then consolidate. Then deduplicate. Repeat. As you scale, it only gets worse.

Your online giving is underperforming. Your data lives in silos. Your team is burning hours on busywork that should be automated.

The Solution

Not just a CRM. Your tech stack for the future.

Site Stacker is a configurable platform that lets you build innovative solutions across your entire organization. Ministries are consolidating their website, CRM, online giving, donor development, automation, reporting, finance tools, marketing, event management, and more — all into one system, one database, one contract.

The Solution

Not just a CRM. Your tech stack for the future.

Mission Aligned

Site Stacker is built by people who share the same mission and passion as the organizations we serve. We're not a secular vendor learning your language — we live it.

Capabilities

Everything your ministry needs. Nothing it doesn't.

Fundraising & Donor Development

Donor developers manage their own lists, set goals, and track progress. Donor scoring, suggested asks, and curated follow-up lists mean your team spends more time building relationships and less time scrolling through data

Workflow & Automation Engine

Bring your entire book of business into Site Stacker and automate every step — applications, onboarding, member care, follow-ups — ensuring nothing gets missed. Event-based automations trigger outcomes from user interactions: categorize donors automatically, generate calculated fields like lifetime giving at the point of donation, fire sequences when thresholds are met. Stack automations on automations for a truly dynamic, responsive environment. Powerful enough to build e-learning systems.

Best-in-Class Online Giving — 81% Conversion Rate

The highest ever studied in the nonprofit industry — compared to the 18% average. Recurring giving incentives, gift size increases, and 150+ international currencies through one checkout. Never-expiring card updates keep donor payment methods current automatically, saving significant revenue every year

Award-Winning Websites

Our design team is trained on the Site Stacker CMS and builds fantastic, functional websites as the front door of your user journey. Need multiple sites? Build as many as you need from one instance — different languages, subsidiaries, campaign microsites — all sharing the same source data, managed from one place.

Configurable Dashboards & Micro CRMs

Low-code dashboards give multi-user access to the same database with role-based permissioning. Create micro CRMs for volunteer managers, missionaries, team leaders, or departments — each seeing only what they need, all pulling from one source of truth. No separate databases. No duplicates.

Business Intelligence & AI Reporting

Dynamic, interactive reports published as tables, charts, graphs, or custom HTML widgets. Real-time data, not static exports. Plus an AI query tool — type natural language and pull any report you need instantly.

Finance Tools

The Pantry tool enables mass batch entry of offline checks and gifts with clean reconciliation from receipt to accounting. Year-end statements sent to every donor with one click — no login required. Gift processing partnerships bring reconciliation back into Site Stacker so you never leave the system to match your bank deposit to your entries.

Email, Text & Automated Sequences

Email and text marketing built in, plus a mail integration that triggers automated sequences from custom user interactions across the system. Set it and forget it — it works for you.

Events, Trips & Volunteers

Short-term trip management lets team leaders sign up, manage teams, and fundraise — all from their dashboard. Event management and volunteer signups are fully integrated, tracked, and automated.

The Data Advantage

Centralize data.

Decentralize access.

When all your systems consolidate into Site Stacker, you centralize your data — but decentralize access to it. Every user interaction happens in one place, giving you real-time data that powers dynamic reports to help you plan rather than react.

One source of truth

No more chasing reports from three departments.

Real-time reporting

Data is live, interactive, and actionable.

No black-box activity

Every interaction is tracked and accessible.

Built to Scale

A system that keeps growing with use.

This isn't a system that gets stuck in the implementation from years ago. Clients learn to build custom dashboards, redesign their own sites, and create new workflows — all within the platform. Site Stacker is built to innovate and scale as you innovate and scale.

By consolidating our software into Site Stacker, we’ve eliminated external automations and simplified tech management—it has been an amazing transition for our team.
