Automating invoices in Switzerland: from QR-bills to payment reminders

If I had to name the single most automatable process in an SME, I would say invoicing. It is repetitive, it follows clear rules and it repeats identically every month. And in Switzerland there is an extra advantage: since the QR-bill replaced the old payment slips, payment data follows a single machine-readable standard. And yet, in many of the companies I meet between Lugano and the rest of Ticino, invoices are still prepared by hand, sent by hand, reconciled by hand and chased from memory.

In this guide I break invoicing down into its pieces and show you what can really be automated, with which tools and how much time you get back. No miracle promises: just what I see working in my process automation projects for SMEs.

The QR-bill has already done half the work

A quick recap of the facts. The QR-bill entered circulation in mid-2020 and on 1 October 2022 it definitively replaced the red and orange payment slips: since that date financial institutions no longer accept them, as the Confederation's SME portal also points out. Today, therefore, every invoice with a payment slip that you issue or receive in Switzerland follows exactly the same standard.

For anyone who wants to automate, this is excellent news. The Swiss QR Code printed on the payment section contains all the necessary data in machine-readable format: beneficiary, amount, currency and reference. And the QR-IBAN + QR reference pair exists precisely to match every incoming payment to the invoice that generated it. The QR-bill is part of the standardization of Swiss payment traffic on ISO 20022, and it is coordinated with eBill: it means that ERPs, banks and accounting software finally speak the same language.

What you can automate, piece by piece

Invoicing is not a single process: it is a chain of five steps, and each one can be automated separately.

• Issuing. From the accepted quote or the fulfilled order to the invoice, without retyping anything. A typical example: an engineering firm that used to copy the quote line items by hand into a Word template; today the invoice with QR-bill is generated in one click from the data already entered.
• Sending. The invoice goes out on its own by email with the PDF attached, or via eBill, straight into the client's e-banking. No more "I had it ready but never sent it".
• Recording incoming payments. The piece with the biggest return. Thanks to the QR reference, bank transactions match themselves to open invoices: the reconciliation that used to take an afternoon becomes a check of a few minutes. And payments recorded properly, every day, also feed your management control: you always know who owes you what.
• Graduated payment reminders. A simple rule: if the invoice is 7 days overdue a gentle nudge goes out, at 20 days a second more formal message, at 35 the real payment reminder. A craft business I worked with used to chase payments "when there was time"; now the system never forgets, and collection times have shortened.
• Archiving. Every invoice issued or collected ends up named and filed in the right place, ready for the fiduciary or an audit. Zero digging through the inbox at year end.

It is no coincidence that when I explain which processes to automate first in an SME, invoicing is almost always at the top of the list: high volume, clear rules, data already digital.

The tools: from your ERP to Power Automate

The question I get most often is "what do you build it with?". The honest answer is: it depends on where you start. In order of complexity:

• The ERP you already have. Many ERPs used in Switzerland issue QR-bills, send payment reminders and read bank transaction files. Often the features are there but nobody has ever configured them: before buying anything, check what you have already paid for.
• Excel plus email plus flows. If today you work with a spreadsheet and your inbox, tools like Microsoft Power Automate connect the pieces: when a row says "invoice overdue" the reminder email goes out, when the payment arrives the sheet gets updated. It is not elegant, but it works and it costs little.
• An integration or a dedicated app. When volumes grow or systems do not talk to each other, you need a custom integration or an application built for this. It is one of the reasons I built my management app: it issues invoices, tracks their status and keeps an eye on incoming payments in one place.

None of these three routes is "the right one" in absolute terms. The choice depends on volumes, on the tools already in house and on how standard the process is: it is exactly the kind of assessment I do at the start of every project.

How much time you get back

Let's take a realistic example, with conservative numbers. An SME that issues 100 invoices a month, working by hand, easily spends 5 minutes per invoice between preparation and sending, a couple of afternoons a month reconciling payments and a few hours chasing late payers. Adding it up, in my experience you often reach 15 to 20 hours a month of pure repetitive administrative work.

With issuing, sending, reconciliation and payment reminders automated, that load typically drops to a few hours of checking and handling exceptions. Valuing administrative time at even just CHF 50 an hour, we are talking about hundreds of francs a month coming back to you, plus the less visible but more important benefit: reminders go out on time and the money comes in sooner. These are estimates, not guarantees: the real number is measured on your process, before and after.

Where to start

If you want to move this week, the path I recommend has three steps.

• 1. Measure the present. For two weeks, note how much time goes into issuing, sending, reconciliation and payment reminders. You need a starting number, even a rough one.
• 2. Activate what you already have. Check what your ERP can do: QR-bill, eBill, reading bank transactions. The first step is often free.
• 3. Automate one piece at a time. It usually pays to start with payment reminders or reconciliation: they are the pieces that weigh the most and are the fastest to automate.

If you would rather not do it all alone, this is the work I do every day: in my process automation service for SMEs we start exactly here, mapping the process and estimating the return before building anything.

The QR-bill has standardized the data; the rest of the work, from issuing to payment reminders, can be automated piece by piece. The first step is understanding how much the process costs you today and which piece is worth automating first: it is exactly where I start with every client.

Frequently asked questions

Does automation work with my current ERP?

In most cases, yes. Many ERPs used in Switzerland already issue QR-bills and read bank transactions: often it is just a matter of configuring features that already exist. If the ERP does not cover a piece, you connect it from the outside with flows or integrations, without replacing it.

Can I automate payment reminders without sounding aggressive?

Yes, and it is actually the best way to handle them. You set up a scale of tones: a first gentle nudge a few days after the due date, then a second more formal message, and only at the end a real payment reminder. The system is punctual and consistent, and you decide the tone.

Is the QR-bill mandatory?

Since 1 October 2022 the old red and orange payment slips are no longer accepted by financial institutions: anyone who wants to be paid with a payment slip must use the QR-bill, or switch to eBill. No law imposes a specific invoice format, but the QR-bill is de facto the Swiss standard for payments.

How much does it cost to automate invoicing?

It depends on your starting point: activating features already included in your ERP can cost almost nothing, a custom flow costs more. I wrote about it in detail in how much it costs to automate a process in an SME: the honest answer is an estimate for your specific case, starting from how much time the process consumes today.
