I built a small script that pulls bank data from Plaid for free without Wave Pro
Since wave is deprecating legacy business's ability to get bank sync for free, I wanted to see if this was something I could automate for free. Thankfully Plaid (the tech that Wave and everyone else uses to pull bank transactions from) just added a free personal tier (they say "trial" but it's free for up to 10 accounts and designed for personal use).
Here's the github repo: https://github.com/jeffreylsoffer/plaid-wave-sync
It's designed with a (hopefully!!) easy to use setup script that runs after clicking the "Open in Github Codespaces" button. Codespaces is just a little computer that boots up letting you go through the plaid register and link process and setting up your wave tokens. Once it's all setup, it'll add a little job to run each day.
Let me know if this actually works for you!
