Tiller is not a budgeting app. It is a bank feed service for spreadsheets. Every day, Tiller pulls your transactions from your bank accounts and pushes them into a Google Sheet or Excel workbook. What you do with those transactions is entirely up to you.
This is both Tiller’s superpower and its barrier. If you are comfortable in spreadsheets, Tiller gives you the raw material for any budget you can design. If spreadsheets make you anxious, Tiller is not the right starting point.
The Sync Reliability Advantage
This is the one area where Tiller has a clear, quantifiable edge over every other app in this category.
Tiller connects to 8,000+ US institutions (fewer than Plaid’s 12,000+) but has a 98.4% success rate versus Plaid’s 94%. More importantly: when a connection breaks, Tiller emails you. You know immediately.
For someone with 4 connected accounts:
- Plaid-based apps (YNAB, Monarch, Copilot): approximately 21% chance of a silent sync failure in any month
- Tiller: approximately 6% chance, and you will be notified
A budget built on missing transactions is not a budget — it is a guess. For users who genuinely rely on their budget data being complete, this reliability difference is the entire case for Tiller.
Pricing
$79/yr. No monthly option. 30-day free trial. This puts Tiller below YNAB ($109/yr) and Monarch ($99.99/yr) at the annual price but above Quicken Simplifi ($71.88/yr).
Spreadsheet Templates
Tiller ships with a Foundations Template (a full budgeting setup in Google Sheets) and access to a community library of 100+ templates. The templates cover zero-based budgeting, debt payoff tracking, net worth tracking, savings goals, and freelance income management.
The quality of the community templates varies. The official Foundations Template is solid. If you are adopting a ZBB workflow in Tiller, plan for 3-4 hours of setup to configure categories and starting balances.
"I switched to Tiller after YNAB sync kept breaking silently. The fact that Tiller emails me when a connection breaks is worth the annual fee by itself."

"Tiller is for people who have graduated from app-based budgeting and want full control. Not for beginners. But if you know what you are doing in Sheets, it is the best tool for serious budgeters."

Data Portability
Tiller’s data portability is the best of any app in this category by definition — your data lives in a Google Sheet or Excel file that you own completely. There is no export process, no format conversion, no vendor lock-in. If Tiller shut down tomorrow, your data remains fully accessible in Google Sheets.
Verdict
Tiller is the right tool for users who want complete data ownership, prefer spreadsheets to apps, and value sync reliability over UI polish. It is not for beginners, but it is uniquely powerful for users who have outgrown app-based budgeting.

Honest Expectation
Honest expectation: Tiller requires investment up front. The first weekend of setup is real work. After that, the daily feeds run automatically and your data is always current. Typical first-year ROI for a serious Tiller user: $1,500-$4,000 — the spreadsheet flexibility lets you build exactly the analysis you need to make decisions.
