Answers to the most common questions — and if yours isn’t here, write to us. We usually reply within one working day.
Click “Try it free” — you’ll be taken to the registration form. You can sign up in three ways: with “Sign up with Google”, with “Sign up with Apple”, or by filling in the form. When you register, you enter your company’s UID (CHE-…). After your first login Synomi will walk you through a few short forms and help you fill in everything you need to get started. For the first 14 days you test Synomi for free — with all the add-on modules.
First of all — don’t panic 🙂 If you log in with your Google or Apple account, check that you’re clicking the right button — the most common reason for login problems is the wrong button. If you log in with an e-mail address, check the address and the password for typos. If two-step verification keeps telling you the code is wrong even though you’ve typed the right one — check the clock settings on your phone. If none of that helps, reset your password (see the next question).
Click “Forgot your password?” and enter the e-mail address you use to log in to Synomi. Synomi will send you a password-reset link. You’ll then be asked for a new password and a 2FA code from your authenticator app. If no e-mail arrives — have a look in your spam folder.
Yes — and we warmly recommend it. It gives you an extra layer of security: your device is authenticated too. If you always log in from the same computer or phone, you won’t have to type in 2FA codes. A key is stored on your computer or phone, and you use it to open Synomi. Remember to allow Synomi access to your data in your Google or Apple account.
Yes — we use two-step verification (2FA) with Google Authenticator. It gives your data in Synomi extra protection. The app is free — you install it on your phone, and during login Synomi asks for the code it generates. Synomi isn’t connected to the Authenticator — it’s magic mathematics that lets both Synomi and the Authenticator know that you are you. When you create your account and set up the Authenticator, a set of one-time recovery codes is generated — in case you need to log in without your phone or the phone goes missing. You then change your password and generate new codes.
Yes — two-step verification is mandatory in Synomi. The app holds your invoices, your clients’ details and your company’s accounting records; a password alone is no longer enough to protect them. Setup takes two minutes and you only do it once — after that 2FA works in the background and you have peace of mind.
Yes. Every invoice automatically gets a Swiss QR-bill (QR-Rechnung) — with a payment part, receipt and QR code. Your clients scan the code in their e-banking and pay without typing anything in.
All three Swiss rates: 8.1 % (standard rate), 2.6 % (reduced rate) and 3.8 % (accommodation). If you are registered for VAT (MWST), your UID and your VAT (MWST) number appear on every invoice. All amounts are in CHF.
Synomi always creates invoices and other documents in German — regardless of the language of the interface. The interface is available in German, French, Italian, Polish, English, Dutch, Ukrainian and Spanish.
The native app for iPhone and Android is coming to Switzerland soon. Until then, you use Synomi in your phone’s browser — add an icon to your home screen and Synomi will start like an app. You’ll find out how on the Mobile app page.
In the browser you need an internet connection — Synomi runs on our server in Switzerland. With the native app (coming soon), your phone is all you need on the road: trips for the mileage log and working hours are recorded on the device and synced as soon as you’re back online.
Log in to your Synomi account on a computer. Go to “My profile” — on the “Subscription” tab you’ll see a “Buy subscription” or “Extend subscription” button. Decide how many months you want, and tick the add-on modules you’d like to use — from there Synomi takes you by the hand. Important: the subscription never renews by itself — it takes your conscious decision and your conscious confirmation. Nothing that touches your finances happens in Synomi automatically.
Extending your subscription and buying add-on modules is only possible on a computer. There are a few good reasons for this. The mobile version complements the main app you use on your computer. We deliberately left some functions out of it — out of respect for your device (for instance, you don’t export documents to your phone — they take up a great deal of storage space). And sometimes you hand your phone to the kids to play — your little one could otherwise extend the subscription without you knowing. We don’t want that. In short: web and phone each have their own jobs and complement each other.
Nothing bad. If you don’t extend your subscription, your account goes into dormant mode — for up to 24 months. During that time you can log in and extend the subscription or download the documents you created in Synomi. You can’t create anything new or change anything, but the documents you issued stay there and you still have access to them. 24 months after the subscription expires — unless you decide otherwise — your documents and your account are deleted from the Synomi servers. Of course, we’ll warn you by e-mail beforehand.
There are several ways to download your documents:
And if you delete your account — on the deletion screen Synomi will offer you a full export of all your data. Download the archive before you confirm: once the account is deleted, your documents cannot be recovered.
Go to “My profile” and click “Delete account”. Synomi will ask you to download an archive of your documents. You’ll then see a statement — read it and confirm with a tick. After you click “Delete”, your account enters deletion mode; after 30 days the process completes and your data is erased for good. You have every right to this under data protection law — details on the Data protection (FADP / GDPR), AI Act and NIS2 at Synomi page. You have 30 days to change your mind: just log in and stop the process with the “Cancel deletion” button. We’ll keep you informed of every step by e-mail. Remember: the obligation to keep your business records and supporting documents for 10 years rests with you.
Synomi’s AI features — Daisy, voice invoicing and receipt scanning (OCR), coming soon in Switzerland — are limited-risk systems under the AI Act. In every process we follow the human-in-the-loop principle: AI only makes suggestions, and every document and every decision requires a human’s conscious approval. Daisy is openly labelled as an AI assistant, in line with the transparency requirements that apply from 2 August 2026. More in plain language: Data protection (FADP / GDPR), AI Act and NIS2 at Synomi.
Synomi, as a small company, is not directly subject to the NIS2 directive — it covers medium-sized and large organisations. We do, however, meet the security requirements that NIS2 makes companies enforce on their suppliers: data kept exclusively on our own server in Switzerland, encryption with a separate key for every company, two-factor authentication, zero trackers.
