From Inbox Chaos to Auto-Booked Invoices: A Step-by-Step Guide to Email Invoice Intake

If you run a small business in Switzerland, you know the routine: a vendor invoice lands in your inbox as a PDF, or gets handed to you as a crumpled receipt, and someone has to manually type the vendor name, amount, MWST rate, and payment reference into your accounting system. Multiply that by dozens of invoices a month, and you've got hours of repetitive work — plus the occasional typo that throws off your books.

Email Invoice Intake changes this by letting your inbox do the data entry for you. Below is a practical, step-by-step guide to moving from the old manual process to a fully automated one.

Step 1: Map out your current manual process

Before automating anything, it helps to see exactly where the friction is. Most Swiss SMEs follow some version of this flow: invoice arrives by email or post, someone opens it, reads the details, opens the accounting tool, types in vendor, amount, VAT, and payment reference, then files or archives the document. Each step is a chance for delay or human error, especially with QR-Rechnung references that are long strings of digits typed by hand.

Step 2: Get your Flitz.ai email inbox

Every Flitz.ai account comes with a dedicated inbox address for invoice intake. Instead of an invoice landing only in your personal or company mailbox, you simply forward it — or better, ask vendors and staff to CC or forward supplier invoices directly — to this address. There's nothing to install and nothing to configure on the vendor's side; they don't even need to know it exists.

Step 3: Forward or scan any invoice format

This is where the manual re-typing stops. Email Invoice Intake accepts PDF, JPG, PNG, and all common formats, so it doesn't matter whether the invoice is a clean digital PDF from a supplier's accounting system, a photo of a paper receipt taken with a phone, or a scanned document from a shared office printer. You forward it exactly as you received it — no converting, no cropping, no manual formatting required.

Step 4: Let the AI OCR do the reading

Once the email arrives, Flitz's AI OCR reads the document and extracts the invoice number, vendor details, individual line items, totals, and MWST breakdown. This is the step that used to take a person several minutes per invoice; the system processes each invoice in under 30 seconds. You don't need to review a wall of raw text — the structured data is pulled out and presented ready for your accounting workflow.

Step 5: Automatic QR-Rechnung and IBAN detection

Swiss QR-Rechnung payment slips are common, but manually transcribing the QR reference number is exactly the kind of task that invites errors. Email Invoice Intake detects QR payment references automatically, and also extracts IBAN and bank details for payment matching. This means the payment information tied to an invoice is captured correctly the first time, without anyone needing to squint at a reference number and type it into a payment form.

Step 6: Review, confirm, and move on

With vendor, amounts, VAT, and payment details already extracted, your job shifts from data entry to quick verification. Instead of building an invoice record from scratch, you're confirming a record that's already been assembled correctly in seconds. This is a meaningful shift in how bookkeeping time gets spent — less typing, more oversight.

Step 7: Build the habit across your team

Once the inbox is set up, the biggest lever for saving time is simply routing more invoices through it. Encourage anyone who receives supplier invoices — whether by email, on paper, or as a phone photo from a site visit — to forward or upload them to the Flitz inbox rather than handling them separately. The more consistently invoices flow through this single channel, the more consistently your books stay current, and the less catch-up work piles up at month-end or during MWST filing periods.

What to expect once you switch

• Invoices no longer need to be manually re-typed regardless of format — PDF, photo, or scan
• Vendor, amount, VAT, and line-item details are extracted automatically within seconds
• QR-Rechnung references and IBAN details are captured for accurate payment matching
• Your team spends less time on repetitive entry and more time reviewing and approving
• Fewer transcription errors in payment references and VAT amounts

You can see the full capabilities of this feature on the Email Invoice Intake feature page. For a small business or a fiduciary managing several clients, this kind of automation isn't about replacing judgment — it's about removing the repetitive typing that stands between an invoice arriving and it being properly booked.

The goal isn't a fancier inbox. It's fewer manual steps between "invoice received" and "invoice correctly recorded."

If your current process still involves opening every PDF and typing numbers into a form, this is a straightforward place to start automating — and one where the time saved compounds with every invoice you receive.
