One expertise, one framework

Do you re-enter the same data in several tools? Does your inventory live in a spreadsheet? Does a quote take days to go out? That is exactly what we eliminate: we build your tools (Build), we run them for you (Run) and we connect them to each other to remove repetitive work (Scale).

Testimonials

What our clients say

Concrete feedback on projects delivered and operated.
IT Director
JDM Distribution
We switched ERP without closing for a single day. Today, the online store and the sales management system talk to each other on their own: nobody re-enters orders anymore. And 411bit takes care of all our IT.
During the migration:
Zero business downtime
Manual data entry:
Eliminated
IT Manager
Industrial mid-sized company, confidential
We knew we had vulnerabilities, without knowing which ones. The audit laid everything out, with a clear, costed action plan. Three weeks later, the most urgent issues were fixed. Not a single incident since.

What kind of work can 411bit carry out for my company?

Build (custom development), Secure (cybersecurity & compliance), Run (managed IT services) and Scale (automation). We work from design through to operations, with no intermediary, for French SMEs and mid-sized companies.

Do you only work with large companies?

No. Our clients range from small businesses (5 people) to mid-sized companies (500 employees). What matters is having an information system to structure, secure or develop further.

Do you hand over the source code at the end of the project?

Always. Every project includes the Git repository, technical documentation and knowledge transfer. Zero vendor lock-in.

Do you use subcontractors?

Engagements are carried out directly by 411bit, with a single technical contact from kickoff to delivery. If additional expertise would help, the use of a partner is presented to you and subject to your approval before work begins.

What is your response time?

Every request receives a reply within 24 business hours. For managed services clients, an SLA with on-call coverage as defined in the contract.

Do you offer support after delivery?

Yes. Every fixed-price project includes a warranty period. Ongoing maintenance and support can be included in the managed services contract.

How does a time and materials engagement work?

You submit your needs, and we send you a quote with a daily rate and a schedule. Billing is based on the days actually worked.

Do you handle emergencies?

Yes. For managed services clients, response times and on-call coverage are set in the contract, according to how critical each service is.

Do you invoice excluding or including VAT?

Our prices are quoted excluding VAT; VAT (20%) is added to the invoice, which shows the total excl. VAT, the VAT amount and the total incl. VAT, in accordance with French regulations.

What payment methods do you accept?

SEPA bank transfer and card payment. For fixed-price projects over €3,000 excl. VAT, payment in 3 installments is available on request.

Are there any hidden fees?

No. The signed quote sets the price for the agreed scope. Any change is covered by an amendment accepted in writing before it is carried out.

Do you offer a proof of concept (POC) phase?

Yes. For complex projects, a POC phase can be offered before you commit to the full fixed-price project.
