01Why send invoices by email?
The classic way: create an invoice in Word, export as PDF, open your email client, attach the PDF, hit send. Sounds simple — but it's a time sink that repeats with every invoice. And the biggest problem: you never know whether the invoice arrived, was opened, or ended up in the spam folder.
PDF attachments are flagged as potentially unsafe by many email providers. This means invoices land in spam or are simply overlooked by the client. Without tracking, you're in the dark — wondering why payment hasn't arrived.
02Creating an invoice in einzly — step by step
Creating an invoice in einzly takes just a few minutes — all mandatory details are filled in automatically. Here's the process:
Choose an existing client from your contact list or create a new one. Name, address, and email are automatically added to the invoice.
Add individual services or products as line items. You can choose from your service catalogue or enter new items directly. Quantity, unit, and unit price per item.
If you're VAT-registered, einzly calculates the tax automatically based on your settings. No manual calculations needed.
einzly supports invoices in German, French, Italian, and English. Choose your client's language — all labels and texts are translated automatically.
Write an optional message to your client. The message appears in the email and gives the invoice a personal touch.
The live preview shows you how the invoice will look to your client — with your logo, accent colour, QR invoice, and all line items.
03Send directly by email
Once your invoice is ready, you can send it directly from einzly by email. No detour via Outlook, no PDF attachment, no manually copying email addresses.
Your client receives a branded email with your logo and company name. Instead of a PDF attachment, the email contains a secure link to the invoice. This has several advantages:
- No PDF that ends up in the spam folder or can't be opened by the client
- You can add a personal message (max. 200 characters)
- The secure link works on any device — desktop and mobile
- The email looks professional and strengthens your branding
04What your client sees
Your client doesn't need an einzly account. They click the link in the email and see a professional online view of the invoice — in their browser, on any device. The view includes:
- Your logo and accent colour — the invoice looks like it's from you, not from einzly
- All line items with unit prices, VAT, and total amount
- The Swiss QR invoice with a scannable QR code for payment
- Payment deadline and payment terms
- Button to download the invoice as a PDF
The online view is fully responsive and works on smartphones, tablets, and desktops. Your client can pay the invoice directly with their banking app by scanning the QR code.
05Swiss QR invoice included
Every invoice in einzly automatically includes a Swiss QR invoice following the SIX standard. The QR code is generated from your profile data (IBAN, address) and invoice data (amount, reference number) — fully automatic, no additional software needed. See our step-by-step QR invoice tutorial for a visual walkthrough.
Your client can scan the QR code with any Swiss banking app and trigger the payment with one click. All payment information is pre-filled — no typos in the IBAN or reference number.
- Automatically generated following the SIX standard
- Compatible with all Swiss banking apps
- IBAN is taken from your profile
- Reference number is created automatically
- Also included in the PDF download
06Status tracking in the dashboard
In the invoice dashboard, you can see at a glance where each invoice stands. einzly uses a clear status system with four stages:
The invoice has been created but not yet sent. You can edit it at any time.
The invoice has been sent to the client by email. You can see the date and time it was sent.
The client has opened the invoice. An eye icon shows you that the invoice has been viewed.
Mark the invoice as paid once payment arrives. If the payment deadline passes, the status automatically changes to 'Overdue'.
Tracking gives you full transparency. You always know which invoices are open, which have been viewed, and where you might need to follow up.
07Payment reminders in 3 stages
When an invoice becomes overdue, einzly helps you with a structured dunning process in three stages:
A friendly reminder about the outstanding invoice. A new payment deadline is set. No reminder fee — the tone stays polite and professional.
A more direct notice about the outstanding payment. You can add a reminder fee and set a new payment deadline.
The last stage before legal action. Includes notice of potential debt collection proceedings under Swiss law (SchKG). Final deadline for payment.
Each reminder stage is sent from einzly — with the same professional appearance as the original invoice. The reminders dashboard keeps you on top of all ongoing dunning processes.
