Custom software for public sector.

Administrations, local authorities, public institutions: public tenders, public accounting (M14/M57), reinforced GDPR, RGAA accessibility by construction. Market solutions are often vertical and rigid, poorly suited to each structure's specific needs.

01What we solve

Three recurring problems.
The same in most firms.

Before talking software, we talk pain points. If you don't recognize any of these three, we are probably not the right partner for you.

  • 01

    Market tools are cathedrals

    Berger-Levrault, JVS-Mairistem, Cegid Public: legacy suites imposed, six-figure subscriptions, long training, limited configuration. No one likes them, everyone pays.

    €100-300k/year on established suites for a mid-sized authority

  • 02

    Citizen portals are dated

    Complex online procedures, not RGAA-accessible, broken mobile journey, hacked-together FranceConnect integration. Citizens end up calling or visiting, instead of the promised autonomy.

    30-50% of online procedures abandoned

  • 03

    Open data is done by hand

    The decree of 28 December 2018 mandates public-data publication. Today: monthly manual exports, never up to date, non-standard format. CADA formal-notice risk.

    CADA risk = public formal notice

02Complex or critical software

The systems that
cannot fail.

When your processes require a replayable audit trail, sagas with compensation, or compliance by construction, we ship an event-driven architecture (DDD + CQRS + Event Sourcing), not a CRUD layered with audit logs.

  • Public-procurement steering

    Public-procurement steering

    Full cycle DCE preparation → BOAMP/JOUE publication → Bid reception → Analysis → Award → Notification → Execution, with clean rollback in case of appeal. History consultable to the Administrative Court or Regional Court of Auditors.

  • eIDAS-signed acts and deliberations

    eIDAS-signed acts and deliberations

    Cycle Act → Council vote → Qualified eIDAS signature → @ctes Prefecture transmission → RAA publication. Each step tamper-proof, history consultable to legality control.

  • M57 accounting with Hélios PAF replayable

    M57 accounting with Hélios PAF replayable

    End-to-end tracking of the cycle Mandate → Authorization → Payment → Accounting. Each entry kept tamper-proof, replayable on Regional Court of Auditors control, compliant with M14/M57 requirements.

  • RGAA AA by construction (DINUM sanctions)

    RGAA AA by construction (DINUM sanctions)

The day-to-day apps,
screen by screen.

For everything else (CRM, portals, scheduling, billing), we ship a custom application, on your design system and with your existing integrations.

04Regulations & integrations

What we handle natively,
no add-ons.

Business compliance and key integrations are not options, they are prerequisites built in from the start.

  • RGAA 4.1.2

    Reference framework for accessibility improvement, level AA mandatory

  • Public Procurement Code

    Public tenders, BOAMP, JOUE, dematerialization

  • M14 / M57

    Budget and accounting nomenclatures for local authorities

  • Public-sector GDPR

    Reinforced right of access, mandatory DPO

  • FranceConnect / eIDAS

    Identification and qualified signature

  • Open Data

    Digital Republic law 2016, decree 28/12/2018

05Frequently asked questions

Answers to the questions we get in meetings.

Do you replace Berger-Levrault / JVS / Cegid Public?
For modules where existing solutions are obsolete (citizen portal, open data, act management), yes. For M14/M57 accounting, we generally integrate rather than replace, the Hélios DGFiP link is complex.
Is the citizen portal RGAA-compliant?
Yes. RGAA 4.1.2 level AA compliance by construction (accessible components, verified contrasts, keyboard navigation, screen readers). RGAA audit possible on request.
Sovereign and SecNumCloud hosting?
Yes. Hosting at Outscale or OVH SecNumCloud per your constraints. Compliant with ANSSI requirements and compatible with sensitive public-data hosting.
Public tenders, do you handle dematerialization?
Yes. BOAMP / JOUE link for publication, PLACE / Maximilien for bid reception, qualified eIDAS electronic signature for award.
How much does it cost for a 20,000-inhabitant municipality?
Subject to functional-scope engagement, no catalogue price. A municipality of this size is typically €80-200k for a module (citizen portal + open data + acts), €12-25k/year maintenance.
06Related industries

Mixed firms (accounting + audit, accounting + advisory, accounting + legal) draw from several industries. Here are those that share the most challenges.
