Google Drive Invoice Sync: Archive Rules and Recovery Source: https://www.getinvoiceagent.com/features/google-drive-invoice-sync Reviewed: 2026-09-14 | Owner: InvoiceAgent editorial team Illustrative example; adapt to your agreement. Not a real client record or live integration test. Example: three invoices in an archive check 1042 — Sent, no archived file: Eligible under either mode. Check for Invoice 1042 - Example Studio.pdf in the chosen folder after sync. 1043 — Paid, no archived file: Eligible under Sent and paid. Sent only excludes this record from the eligible-invoice batch. 1044 — Pending: Not eligible. Preparing a draft does not put its PDF into this archive. 1042 later becomes Paid: The existing file ID causes a skip. The previously archived PDF is not automatically refreshed. Illustrative eligibility example, not a live Google account test. An archived invoice is a document copy; use the current billing record to check payment and balance.

Choose the account and destination Connect Google Drive from your InvoiceAgent account and check the selected folder. Confirm its name and sharing settings before eligible invoices are copied. Use a destination your billing owner can find without exposing unrelated client invoices through unnecessarily broad sharing. 2. Set the eligible invoice mode Choose Sent only or Sent and paid according to the records you want included. If older Paid invoices have never been archived, use Sent and paid before running the eligible-invoice sync. Review the reported synced, skipped, and failed counts instead of assuming every invoice creates a new file. 3. Open a file and record the result Check the invoice number, client, amount, and currency in the saved PDF. For a failure, inspect the recorded sync error and correct the connection or folder access before retrying archive work. If email delivery is already Sent, leave that delivery intact while investigating the missing copy. EXCEPTIONS AND LIMITS Existing file IDs prevent replacement Sync skips invoices already linked to a Drive file. It does not automatically repair a PDF you deleted in Drive, move an old file into a newly selected folder, or regenerate it after payment. Verify existing copies before relying on a folder change to reorganize history. Disconnecting is not an archive cleanup Disconnecting clears the stored connection and invoice file links in InvoiceAgent; it does not delete the existing Drive PDFs. Reconnecting and syncing the same invoices can therefore create additional copies. Check the old folder before doing a broad resync. A file copy is not a live payment ledger The archive can contain the PDF generated when an invoice was sent. Later payment updates do not automatically replace that file. Check the current invoice balance for collections work and keep the archive's document role clear.
