Bank Sync

Treeline supports automatic bank sync through two third-party services. Both are paid subscriptions that you manage separately from Treeline.

Service	Coverage	Price	Best For
SimpleFIN	US & Canada	$1.50/month	US/Canada users
Lunch Flow	Global	~$3/month	US, Canada, Brazil, EU, UK, Asia

Both services are read-only. They cannot move money or make changes to your accounts.

Setup

SimpleFIN

1. Create an account at beta-bridge.simplefin.org
2. Connect your bank accounts through their interface
3. Create a new connection for Treeline and copy the setup token
4. In Treeline: Settings > Integrations > Add SimpleFIN, paste the token

Or via CLI:

tl setup simplefin <your-setup-token>

Lunch Flow

1. Create an account at lunchflow.app
2. Connect your bank accounts
3. Go to Destinations, create an API destination, and copy the API key
4. In Treeline: Settings > Integrations > Add Lunch Flow, paste the key

Or via CLI:

tl setup lunchflow <your-api-key>

Syncing

After setup, click the sync button in the header or run:

tl sync

First sync pulls 90 days of history (SimpleFIN) or all available history (Lunch Flow).

Future syncs pull recent transactions with overlap to avoid gaps. Treeline deduplicates automatically - your edits (tags, descriptions) are preserved.

Account Mapping

After your first sync, Treeline shows all discovered accounts. You can:

• Map a synced account to an existing Treeline account
• Create a new account automatically
• Exclude accounts you don’t want to track
• Balances only - sync balance but skip transactions (useful for investment accounts)

These settings persist between syncs.

Troubleshooting

Authentication errors (401, 403)

Your credentials may have expired. Log into your provider’s dashboard, verify bank connections are active, and generate a new token/key if needed.

Payment required (402)

Your subscription needs renewal. Check your billing in the provider’s dashboard.

Missing transactions

Banks vary in reporting speed. Some update in real-time, others batch overnight. Wait 24-48 hours and sync again.

Removing an integration

tl setup remove simplefin
tl setup remove lunchflow

Your transaction history stays in Treeline. Manage your subscription at the provider’s site.
