How a Nonprofit Replaced $110/mo Zapier With $0 AWS Lambda

A nonprofit we work with was paying $110 a month for Zapier — $1,320 a year — to run a single, simple automation: when a document landed in a shared Google Drive folder, fire off a webhook to notify another system. One trigger, one action. That's it.

This is one of the most common traps we see with small teams and nonprofits. A tool like Zapier is genuinely great, but it's priced for organizations running hundreds of complex, high-volume workflows. When you're using it for one small job, you're renting a warehouse to store a single box.

The reality check: you're nowhere near the limits

Their automation ran a few thousand times a month — well under one million requests a year. That number matters, because it sits comfortably inside the AWS Lambda free tier, which covers 1 million requests per month plus 400,000 GB-seconds of compute, every month, indefinitely — not a 12-month trial.

So the same job that cost $1,320/year on Zapier costs $0 to run on Lambda.

The Zapier subscription vs the same workload on the AWS Lambda free tier.

That's a 100% infrastructure cost reduction — not a discount, not a downgrade. The software line item goes away entirely.

The build: six hours, done right

Anyone can wire up a webhook. The value isn't the code existing — it's the code being written by someone who does this for a living. Our team spent a total of six hours writing and testing the Lambda function: the Google Drive trigger, the webhook call, retry-and-error handling so a failure doesn't vanish silently, structured logging so it's observable, and a least-privilege IAM role so the function can do its one job and nothing else.

That last part is the difference between a script and a system. A DIY Zapier replacement often leaves a long-lived API token sitting inside a third-party tool. Our build keeps the credentials and the execution inside the client's own AWS account, scoped down to exactly what's needed. Our team holds CISSP and AWS Certified Security credentials, and we're an AWS Partner — security isn't a step we add at the end, it's how we build.

The model: you don't pay unless you save

Here's the part that makes this easy to say yes to. We did this on a four-year cost savings agreement: we take half of the realized savings, and the client keeps the other half. No upfront invoice, no risk. If the automation didn't save money, we wouldn't get paid.

Client keeps — $660WTC share (4 yrs only) — $660

The client keeps half from day one; after the 4-year term, they keep all of it.

For us, the six-hour build paid for itself inside the first year — the agreement was net-positive ROI after year one. For the client, the math is even better over time: they save $660 every year during the agreement, and once the four years are up, the Lambda function keeps running for free and they keep the entire $1,320/year.

Stay on ZapierLambda + WTC agreement

Staying on Zapier vs. the Lambda build with the 4-year 50/50 agreement. The fee ends after year 4; the savings don't.

By year five, doing nothing has cost $6,600. The switch has cost $2,640 total — and $0 going forward.

This is FinOps, not a one-off

One automation is a small win. The reason it matters is that almost every organization has a stack full of these — SaaS tools priced for scale you don't have, subscriptions nobody remembers signing up for, and workloads that would run for pennies (or free) on the right infrastructure.

That's what FinOps is: treating cloud and software spend as something you actively engineer down, not a fixed cost you accept. Finding one $1,320/year line is nice. Finding the pattern across your whole stack is transformational — especially for a nonprofit, where every recovered dollar goes back into the mission.
