Automatic SaaS invoice and receipt collection, every month

At the end of each month, your bookkeeper asks for every invoice from every subscription: OpenAI, Google Workspace, Notion, Slack and the rest. Many SaaS tools only email a payment notice and keep the invoice itself behind a billing login: the OpenAI API, Notion, Atlassian, Vercel, Cloudflare and many more. So a founder logs in to each tool, finds its billing page, downloads the PDF and renames it, one subscription at a time. With Reduck, your agent collects them all and emails them to your bookkeeper or accountant in one prompt, and the same prompt works every month.

Why SaaS invoice collection stays manual

  • The invoice is not always in your inbox. An email rule or an inbox scanner catches the tools that send a PDF. The rest only show the invoice once you log in to their billing page.
  • Every billing page is different. Each tool puts its invoices in a different menu, with a different layout and a different download button.
  • There is rarely an API. Billing pages are made for people, so there is no shortcut an accounting tool can call.
  • It is easy to miss one. With a dozen subscriptions, one forgotten invoice is enough to hold up the month-end close.

How Reduck collects your SaaS invoices

Reduck runs ready-made scripts in your own browser, where you are already signed in. For each tool, your agent lists the invoices on its billing page and downloads the PDF of the month you asked for. Tools billed through Stripe share one download script, so a Stripe-hosted invoice link from any of them becomes a PDF.

  1. Tell your agent which month and which tools.
  2. It opens each billing page in your browser session and lists the invoices.
  3. It downloads each PDF and names it by tool, month and amount.
  4. It emails each invoice to your accountant from your Gmail, or saves them together in one folder.
  5. It lists any tool it could not reach, so nothing slips through.

Reduck and invoice collectors

GetMyInvoices, Invoice Radar and invoicefetcher are invoice collectors: you connect your portals, and they fetch on a schedule into their own archive. Dext and Hubdoc read what arrives by email. Reduck is for teams that already work with an AI agent: the agent collects the invoices in your own browser, and it can send them to the inbox your Dext, Hubdoc or Xero account gives you, so the tools work together. The GetMyInvoices alternative page compares them.

Who it's for

  • Founders and operators who do their own books
  • Finance and FinOps teams closing the month
  • Accountants and bookkeepers collecting invoices for several clients

FAQ

Yes, that is what it is built for. Many tools keep the invoice behind a billing login and only email a notice. Your agent opens each billing page in your own browser session, lists the invoices and downloads the PDFs, the same way you would by hand.
Most use an email rule for the tools that attach a PDF, and log in to the others by hand at month-end. Invoice collectors such as GetMyInvoices and invoicefetcher fetch from portals in their cloud. If you already use an AI agent, Reduck collects them in your own browser from one prompt, and sends them to your bookkeeper. The GetMyInvoices alternative page compares them.
About 40 billing portals have a ready-made script, among them OpenAI (API and ChatGPT), Claude and the Anthropic Console, Cursor, Slack, Google Workspace, Notion, Atlassian, Asana, Miro, Linear, ClickUp, Airtable, Dropbox, HubSpot, Zapier, Calendly, Vercel, Supabase, Neon, Cloudflare, DigitalOcean, GitHub and Hostinger. One more script downloads the PDF of any invoice hosted by Stripe. AWS has no ready-made script yet. For a tool that is not covered, your agent can write the script once and reuse it every month.
A billing page can change and break a script. The scripts are shared in Reduck's catalogue, so a script that breaks is repaired once for everyone who uses it, and your agent can also fix or write one in your browser when a page it needs has changed.
Each tool reports its own result. A tool it could not reach, or a month with no invoice, is listed separately. Give your agent the list of subscriptions you pay for, and it tells you which ones have no invoice for the month.
The invoices come back as PDF files. Your agent can email each one from your own Gmail, to your accountant or to the inbox address your accounting software gives you (Dext, Hubdoc and Xero each have one), or save them in a folder you share.
It runs in your own Chrome with the sessions you already have, so there are no passwords to share and no new account to connect. Nothing is fetched that you could not open yourself.
Save the prompt and ask your agent to run it at the start of each month; the same scripts collect the new invoices each time.
Those are invoice collectors and managers. GetMyInvoices and Invoice Radar say they fetch from web portals and email, and add their own archive and exports. Reduck is for teams that already use an AI agent. The agent collects the invoices in your own browser from a prompt, and can write a script for a portal that is missing. See the GetMyInvoices alternative page for the full comparison.
