Services
Five offers, depending on the scope of your need
The offers follow one another. An MVP tests the idea first, then the application, the site or the product is built, and the maintenance contract follows it once the tool is in service. If your application already exists and was built with an AI tool, the audit first checks how solid it is.
01
Prototype and MVP
This offer covers the building of an MVP, that is a first version of your application that really works but is limited to the features that matter.
It lets you test the idea with real users before committing the budget of a full version. The code is written to be kept, so the rest of the project extends it instead of rewriting it.
For whom
A freelancer, a company or a project owner who wants to test a service, an application or an internal tool before funding its full version.
What is included
- framing that keeps the features that matter and sets the rest aside;
- development of a mobile or web application in working order, with its server when needed;
- distribution to your first users, in testing or on the stores;
- monitoring of errors and feedback during the first weeks.
What you receive
- the application in service, with its accesses;
- the source code, in a repository in your name;
- the list of changes to plan, drawn from the users’ feedback.
02
Mobile applications
This offer covers the creation of a mobile application, or the takeover of an existing one, up to its release on the stores.
The choice between Flutter and native development is made at the framing stage, according to the expected features and the team that will take over afterwards.
For whom
A freelancer or a company that wants to offer an application to their customers or teams, or whose application has become hard to develop further.
References: Locwind, published on Google Play, and the migration of the navigation of a financial services application, led at Automata AI.
What is included
- design of the screens from your user journeys;
- Android and iOS development, in Flutter, Swift or Kotlin;
- release on Google Play and on the App Store;
- monitoring of stability and errors after going live.
What you receive
- the source code, in a repository in your name;
- the publishing accounts, also in your name;
- documentation that lets another developer take over the project.
03
Custom sites and products
This offer covers the sites and tools your business needs, from a showcase site of a few pages to a business tool with a server, a database and an administration interface.
A single point of contact is accountable for all of it, from design to going live and hosting.
For whom
A freelancer, a craftsperson, a shopkeeper or a company that needs a site to present their business or to sell online, or a company whose business rests on a tool that off-the-shelf software covers poorly: tracking of files, customers, stock or rewards.
References: Iforla, the site of a language school with its enrolment module, Adanora, an online subscription shop, and myFenyx, the mobile application, server and administration interface that manage the rewards of Fenyx Group’s consultants.
What is included
- framing of the need and division of the project into stages;
- design of the pages or screens;
- server, database and administration interface, when the project calls for them;
- site, shop or application for your customers and your teams;
- going live and hosting.
What you receive
- the site or the product in service, with its administration accesses;
- the source code and the technical documentation.
04
Maintenance and hosting
A tool in service needs regular care, because operating systems, stores and dependencies keep changing.
The monthly contract provides that care, whether the tool was built by Cofinger or by another provider. In the second case, an audit comes before the takeover.
For whom
A freelancer or a company that has an application or a site in production and wants to entrust its upkeep.
Reference: the server that hosts the projects of Cofinger, with error tracking and code quality analysis, described in the article Monitoring.
What is included
- fixes and small changes, within a volume set in the contract;
- updates of Android, iOS and dependencies;
- hosting, backups and certificates;
- monitoring of errors and availability.
What you receive
- a monthly report of the work done and of the incidents.
05
Audit of an AI-generated application
This offer is for applications built, in whole or in part, with a coding assistant or an AI application generator. These tools quickly produce an application that works in a demo, but they can leave security holes, poorly protected data or code that is hard to evolve.
The audit examines the application before you put it in your customers’ hands. It ends with a report that ranks the problems by severity and proposes a plan of fixes, which Cofinger can then carry out or your team can follow.
For whom
A freelancer, a company or a project owner who built their application with an AI tool and wants to be sure it will hold up with real users.
Reference: the new version of Sanu, written mostly with a coding assistant, each delivery of which passes an automatic check, following the method described in the article on the plugin repository.
What is included
- a security review: authentication, access rights, secrets and dependencies;
- a data review: its structure, its protection and its backups;
- a code review: its readability, its tests and its capacity to evolve;
- a check of readiness for the stores and for production.
What you receive
- a report that ranks the problems by severity;
- a costed plan of fixes;
- a meeting to present the conclusions to you.

What makes the cost vary
Each project is costed after the first conversation. Four elements weigh most on the amount:
- the number of pages, screens and journeys to design;
- the presence of a server and an administration interface;
- the connections to other software, such as a payment service or an ERP;
- offline operation, when it is needed.
Billing
Building an MVP, an application, a site or a product is billed at a fixed price, in stages. Maintenance and hosting are billed monthly. The quote states what is included, what is not and the planned schedule, and the terms of sale complement it.
