Build aB2B SaaSthat lasts
A B2B SaaS product becomes serious when onboarding, accounts, permissions, billing, and support hold together without hacks or manual patchwork at every step.
The benefits :
The projects we build most often :
Launch a B2B SaaS with accounts and roles
As soon as a product must handle several client companies, several users, and several access levels, accounts, roles, and permissions must be structured from the first version.
Structure onboarding and product activation
A good SaaS does not start at sign-in. It starts with the steps that move an account from sign-up to real usage, with invitations, setup, data import, and the first useful actions.
Recurring billing and plan logic
Subscriptions, trials, usage limits, paid options, and payment issues must be framed early to avoid a monetization layer patched around the product.
Move from an MVP to a maintainable SaaS
The move to V2 often requires revisiting data, roles, administration, observability, and technical debt before adding new features.

Community platform & subscriptions
A single product base to handle accounts, bookings, recurring operations, and back office inside the same workflow.
We needed a tool able to manage a fleet of self-service machines. Koragence structured a clear, robust platform we can rely on every day.
Supervision business software
Onctuo currently manages ten machines in the same business environment, with statuses, alerts, and incidents reviewed without manual reprocessing.
What budget should you plan for a credible B2B SaaS?
Useful technologies on this kind of topic :
Accounts, subscriptions, and SaaS continuity
Manage spaces, roles, and permissions by client or team.
The product must separate administrators, users, guests, and internal teams without mixing data between accounts.
Keep permissions, status, and billing in the same product logic.
Trial, active plan, suspension, quota, or paid option must stay coherent with the access that is actually open.
Prepare monitoring, backups, and support from the first customers.
The foundation must stay easy to evolve, fix, and recover if an incident affects production or billing.
Experts we can mobilize :
Our experts and collaborators come from top schools:
Schools represented in the Koragence network include EPITA, EPITECH, ESSEC Business School, HEC Paris, École Polytechnique, and CentraleSupélec.

Why Koragence?
Transparency, our priority in your project
Our client workspace gives a direct view of the project: roadmap, remaining tasks, current step, documents, specifications, meeting notes, invoices, and client feedback. Decisions stay visible, dated, and actionable.
A partner that stays after launch
Launch does not close the topic. We handle maintenance, security, functional evolutions, performance follow-up, and technical trade-offs so the product can evolve without starting over.
The right expertise on a foundation that stays readable
Development, architecture, user experience, artificial intelligence, cybersecurity, infrastructure, data, and integration are brought in according to the real need. All of it sits on a documented, maintainable foundation that is easy to take over.
Frequently asked questions :
Cost mostly depends on the number of roles, screens, integrations, approvals, and the level of continuity expected once the project is live.
Also worth exploring :
Overview of Koragence offers and entry points.
We design custom web applications and SaaS products to manage accounts, roles, documents, statuses, workflows, and business operations inside a clear, maintainable interface.
Mobile becomes relevant when a team must scan, enter, photograph, track, or approve in the field without going back through a desk afterwards.
Design becomes a priority when a screen slows people down, a status stays unclear, or a user has to think too long before completing a simple action.
The issue becomes critical for training providers when enrollments, agreements, attendance, Qualiopi documents, and follow-ups live in too many separate tools.
In an association, software becomes central when memberships, donations, events, supporting files, and communication still rely on manual follow-ups and exports.
Flutter is a strong fit for mobile applications that want a very consistent interface, a shared iOS and Android base, and a product scoped properly from the start.
Laravel fits well for portals, APIs, and internal tools that need delivery speed without completely sacrificing structure, provided conventions remain strict.
