Answers to the most common technical questions — and if yours isn’t here, write to us. We usually reply within one working day.
Click the “Try it free” button — you’ll be taken to the registration form. You can sign up in three ways: with the “Sign up with Google” button, with “Sign up with Apple”, or by filling in the form. 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 switched on.
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 people can’t log in is pressing the wrong one. If you log in with an e-mail address, check for typos in the address or the password. 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 — see how to reset your password (the question below).
Click “Forgot your password?” and enter the e-mail address you use to log in to Synomi. Synomi will send a password-reset link to your inbox. You’ll then be asked for a new password and a 2FA code from your authenticator app. If the message doesn’t arrive — 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 keep logging in from the same computer or phone, you won’t have to type in 2FA codes. A key will take up residence on your computer or phone, and you’ll use it to open Synomi. Remember that you need to allow Synomi access to your data in your Google or Apple account.
Yes — we use two-step verification (2FA) with Google Authenticator. It’s an extra layer of protection for your data in Synomi. 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 in any way — 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 ever need to log in to Synomi 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 documents; 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.
You can download the Android app directly from us — with a three-step guide on the Mobile app page. Verification on Google Play is also under way; once the app is published there, it will offer to switch you over to the store version by itself.
The iOS version is going through Apple’s review right now — we’re on the home straight. You’ll always find the current status on the Mobile app page.
Yes and no 🙂 Synomi lives on our servers in the cloud — to send invoices, use Daisy and get through all the paperwork you need an internet connection. But when you’re on the road recording your mileage, the app on your phone is all it takes. Once you’re back online, Synomi syncs your trip and saves how it went. Timesheets work the same way — your working hours are collected on the phone and then synced with Synomi’s servers.
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, tick the add-on modules you’d like to use — from there Synomi takes you by the hand. Remember that 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 app complements the main app you use on your computer. We deliberately left some functions out of it, out of respect for what’s yours (for instance, you can’t export documents on the phone — they take up a great deal of space), and in return we gave it functions your computer can’t handle (the GPS recorder, voice control). And you sometimes hand your phone to your kids to play with — your little one could extend the subscription without you knowing. We don’t want that. In short: the two halves of Synomi — web and mobile — each have their own unique functions and complement each other.
Nothing terrible. If you don’t extend the subscription, your account goes into hibernation — for as long as 24 months. During that time you can log in and extend the subscription, or download the documents you created in Synomi. You won’t be able to create anything new or change anything, but the documents you issued in Synomi are still there and you still have access to them. Once 24 months have passed since the subscription ended — unless you decide otherwise — your documents and your account will be removed from Synomi’s servers. Of course we’ll warn you about it by e-mail.
There are several ways to download your documents:
And if you’re deleting 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.
You can delete your account in the mobile app as well as in the app on your computer. Go to “My profile” and click “Delete account”. Synomi will ask you to download an archive of your documents. Once you’ve downloaded it, you’ll see a statement — read it and tick that you have. 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 the GDPR — details on the GDPR / AVG, AI Act and NIS2 at Synomi page. You have 30 days to change your mind. Just log in and stop the process by clicking the “Cancel deletion” button. We’ll keep you informed of every step by e-mail. Remember: the obligation to keep your accounting records for 7 years rests with you.
Synomi's AI features — Daisy, voice invoicing, OCR — are limited-risk systems under the AI Act. In every process we follow the human-in-the-loop principle: AI only suggests, 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: GDPR / AVG, AI Act and NIS2 at Synomi.
Synomi, as a small company, is not directly subject to the NIS2 directive — it covers medium 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 the Netherlands, encryption with a separate key for every company, two-factor authentication, zero trackers.
