Finance and accounting decision

Tiller

A narrow replacement (feeds into Google Sheets, rule-based AutoCat, daily email) is realistic for a competent developer using existing aggregators and APIs, but reproducing Tiller’s ongoing bank-connector coverage, reliability, and support is costly and operationally heavy, so keeping the paid service is reasonable for full parity.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Tiller alternatives, with the arithmetic →

What a replacement has to do

  • Fetch account transactions daily, append and normalize rows into a spreadsheet, auto-categorize transactions using rules/ML, surface summary templates/dashboards and send a daily summary email.

What it still won’t have

  • Tiller-managed bank connector reliability and connector maintenance
  • Prebuilt, polished spreadsheet templates and one-click setup
  • US-based dedicated customer success/support team
  • Daily hosted feed management and guaranteed privacy controls
  • Auto-updates and built-in AutoCat behavior tuned by the vendor

What remains hard

  • Integration maintenanceOnly Tiller connects your banks and spreadsheets with an automatic feed of your daily finances.

Runnable build prompt

Not run yet
Build a hosted service using Node.js (or Python) + Postgres + Google Sheets API + a Plaid (or similar) connector to: 1) connect a single user’s bank accounts via Plaid and fetch daily transactions; 2) normalize and dedupe transactions and store them in Postgres; 3) write transactions into a Google Sheet using the Sheets API and maintain a Foundation Template sheet; 4) implement rule-based AutoCat categorization with a small ML fallback using a hosted transformer endpoint (or simple logistic regression) and an admin UI to edit rules; 5) send a daily summary email via SendGrid. Out of scope: building your own bank aggregation network (use Plaid/Envestnet/Yodlee), multi-user billing UI, and Excel desktop automation (optional: implement Microsoft Graph later). Include error handling for failed bank fetches, retry/backoff, monitoring (Sentry), and unit/integration tests for connectors, categorization, and Sheets writes.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
