Auto-Generate Invoice When Project Completes in Google Drive
Mark a project complete in Drive, and Notis automatically creates the invoice in Stripe. Your billing moves at the speed of your work.
Trigger
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Action
Create an invoice
Creates a new draft stripe invoice for a customer; use to revise an existing invoice, bill for a specific subscription (which must belong to the customer), or apply detailed customizations.
Why this helps
You finish a project, update your tracker in Drive, then have to remember to switch to Stripe and manually create an invoice. Often it's days later, and clients wonder why they haven't been billed.
- Invoice clients instantly when work is complete, not days later
- Keep your billing perfectly in sync with your delivery schedule
- Remove the context switch between Drive and Stripe
- Reduce time chasing down 'where's my invoice?' messages
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Stripe to Notis (one-time in the portal).
- 2Create an automation: 'When a project row in my tracker is marked complete, create an invoice in Stripe for that client.'
- 3Select the trigger 'File Updated' and choose your notification channel.
- 4Test by marking a small project complete and verify the invoice appears in Stripe within seconds.
Questions about this workflow
What if I update my project sheet for other reasons?
Notis only triggers the workflow when a specific status column or keyword (like 'complete' or 'done') changes, so routine updates won't accidentally create invoices.
Can it pull the amount from my spreadsheet?
Yes. If your tracker has a 'total due' or 'amount' column, Notis will read that value and use it to create the invoice. You can also set flat rates per project type.
Do I still need to fill in line items manually?
Notis creates the draft invoice with the amount and customer. You can add line items in Stripe before finalizing, or pre-configure templates in your automation prompt for standardized services.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Stripe. A trigger fires from one place; an action lands in another.
Google Drive triggers
Stripe actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Cancel subscription
Cancels a customer's active stripe subscription at the end of the current billing period, with options to invoice immediately for metered usage and prorate charges for unused time.
File Created
Triggers when a new file is created in Google Drive.
Confirm payment intent
Confirms a stripe paymentintent to finalize a payment; a `return url` is necessary if the payment method requires customer redirection.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Create Customer
Creates a new customer in stripe, required for creating charges or subscriptions; an email is highly recommended for customer communications.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
Create an invoice
Creates a new draft stripe invoice for a customer; use to revise an existing invoice, bill for a specific subscription (which must belong to the customer), or apply detailed customizations.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Create payment intent
Creates a stripe paymentintent to initiate and process a customer's payment; using `application fee amount` for a connected account requires the `stripe-account` header.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Create a price
Creates a new stripe price for a product, defining its charges (one-time or recurring) and billing scheme; requires either an existing `product` id or `product data`.
New File Matching Query
Triggers when a new Google Drive file matches a provided query. This is the legacy query-centric trigger: it preserves Drive API query config such as ``corpora`` / ``driveId`` aliases and emits the historical ``file_matching_query`` event type. ``FileCreatedTrigger`` covers the broader "new file" case and emits ``file_created``.
Create product
Creates a new product in stripe, encoding the request as `application/x-www-form-urlencoded` by flattening nested structures.
Create Refund
Creates a full or partial refund in stripe, targeting either a specific charge id or a payment intent id.
