Étienne Collet — Software developer, Noisy-le-Grand
A helping hand for you, more time for your customers.
I help craftspeople, shopkeepers and small businesses stay compliant and save time: e-invoicing, websites, automations and AI training.
What I do for you
E-invoicing
Choosing an approved platform, setup, importing your customers and a one-hour training, ahead of the September 2027 obligation.
Learn more
Good to know
E-invoicing goes through a platform approved by the tax authorities: it sends your invoices and receives your suppliers' ones. Once the deadline arrives, a plain PDF will no longer be enough, and a €15 fine per invoice is planned. Getting ready a few months ahead lets you choose calmly and find your feet.
What I do for you
- I compare the approved platforms for your activity and budget, and help you choose.
- I set up your account, import your customers and items, and check that a first invoice goes through.
- I train you for an hour, with a memo for later, and stay reachable for your first invoices.
Key dates
Receiving becomes mandatory for every business.
Issuing becomes mandatory for small and micro businesses.
Digital product passport
Setting up the digital product sheets (QR code) gradually required by European regulations.
Learn more
Good to know
Europe is introducing a digital product passport: a QR code presenting a product's composition, origin and how to repair it. It is being rolled out gradually, product family by product family, starting with batteries in 2027. It is also a great opportunity to showcase the quality of what you make or sell.
What I do for you
- I check whether your products are concerned, and from which date.
- I gather the required information with you and put it into shape.
- I generate the QR codes and each product's page, hosted and easy to update.
Website
A 5-page showcase website, an up-to-date Google listing, a contact form and online booking.
Learn more
Good to know
A business website displays a legal notice and a privacy policy, and asks visitors for consent before using analytics or advertising cookies. These are a few simple pages and settings that also reassure your customers: best to plan them from the start.
What I do for you
- A 5-page showcase website, fast, readable on a phone and accessible.
- Your Google listing up to date: opening hours, photos, reviews and a booking link.
- Legal notice, privacy policy and cookie management, compliant from day one.
Automations
Quote and unpaid invoice reminders, appointment reminders, Google review requests: fewer repetitive tasks.
Learn more
Good to know
For effective, stress-free reminders, remember to state late payment penalties and the €40 fixed recovery fee on your invoices to businesses. And when writing to consumer customers, asking their consent first remains good practice: it avoids unwelcome messages.
What I do for you
- I identify with you the repetitive tasks that take up most of your time.
- I automate reminders, appointment notifications and review requests, with your current tools when possible.
- I show you how to monitor and change everything, without depending on me.
AI training
A half-day to use ChatGPT or Claude for your quotes, e-mails and posts.
Learn more
Good to know
Used well, AI saves precious time. Two habits are enough to adopt it with confidence: taking the time to learn how to use it, which Europe also recommends to businesses, and avoiding pasting your customers' personal data into it.
What I do for you
- A half-day on your real cases: quotes, e-mails, posts, replies to reviews.
- Ready-to-use instruction templates (prompts), adapted to your trade.
- The right habits: checking what the AI produces and protecting your customers' data.

Pick a slotFrequently asked questions
How much does it cost?
The one-hour audit is free and without commitment. Within 24 hours, you receive written recommendations, each with an estimate of its price and setup time. You then choose what to launch, at your own pace: nothing is committed until you approve a quote.
I am not comfortable with computers, is this for me?
Yes, it is precisely for you. I start from your tools and habits, explain without jargon and leave you a step-by-step memo. Training uses your own examples, and I remain available by phone or e-mail if you get stuck afterwards.
Do you come on site?
Yes, I come to Noisy-le-Grand and the neighbouring towns, to your premises or workplace. Elsewhere, we work by phone or video call with screen sharing: most setups work very well remotely.
Does e-invoicing concern me?
Yes, as soon as you invoice other businesses in France, even as a sole trader. Since September 2026, you must be able to receive electronic invoices through an approved platform; from September 2027, you will also have to issue them and report your sales to consumers and abroad (e-reporting). It is best to prepare a few months ahead, to get used to the platform without pressure.
Is there funding for these projects?
Depending on your region and activity, digitalisation grants for small businesses may exist, and some training can be funded by your training fund (OPCO or FAF). Conditions change often: during the audit, we check which ones you are entitled to before pricing anything.
Do my accounts and data remain mine?
Yes. Accounts (invoicing platform, website, automation tools) are created in your name and you keep the access. If you stop working with me, everything keeps running, and I hand over the documentation of what was set up.
