Google Drive Integration

2026-05-24

Haiku can save invoice PDFs and expense files directly to your Google Drive, with a consistent folder structure and file naming so everything stays organised without manual filing.

Authorizing Drive

Go to Settings → Google Drive.
Click Connect Google Drive and complete the Google authorization screen.
A confirmation appears once Haiku has permission to create files in a dedicated Haiku folder.

Haiku only ever writes to its own folder tree. It does not read or list other folders in your Drive.

Folder Structure

Files are placed under a top-level Haiku.lt folder, split by type and year:

Haiku.lt
  ├── Invoices
  │     └── 2026
  │           └── INV-2026-045.pdf
  └── Expenses
        └── 2026
              └── 2026-05-12-acme-supplies.pdf

The year folder is created automatically the first time a file is uploaded for that year.

File Naming

Invoices — the file is named with the invoice series and number (e.g. INV-2026-045.pdf). Locking and re-saving overwrites the existing file rather than creating a duplicate.

Expenses — files are named with the expense date and a slug of the seller or description (e.g. 2026-05-12-acme-supplies.pdf), making them easy to find without opening.

When Files Go Where

Action	File saved to Drive?
Create invoice	No — manually save via Save PDF to Drive or batch-save in Multi-Edit
Lock invoice	No — locking is independent of Drive
Send invoice via email	No — Drive save is a separate action
Add expense with “Upload to Drive” checked	Yes — uploaded during Step 3
Multi-Edit → Save PDFs to Drive	Yes — batch-uploads selected invoices
Delete expense	No — file stays in Drive; use Delete from Drive on the card

This separation is intentional: locking and sending are about accounting state, while Drive storage is about archival. They can happen at different times.

Bulk Operations

For sending an entire month of invoices to Drive at once, use the batch-edit wizard — it includes both Save PDFs to Google Drive and Delete from Google Drive operations.

Revoking Access

To disconnect Drive: Settings → Google Drive → Disconnect. Existing files in Drive remain in place — disconnecting only stops Haiku from uploading new ones.

You can also revoke access from Google directly at myaccount.google.com/permissions. Haiku will detect the revocation on the next upload attempt and prompt you to reconnect.
