Diversify
A cloud SaaS solution available everywhere and all the time

Perfect
SaaS scalability, the extra service
SaaS ERP is scalable and follows your business's demands regarding data or transaction growth. In case of updates, disruptions are reduced and don't alter the application's operation.
Facilitate
Rapid SaaS deployment and adoption
The SaaS ERP system is designed to integrate easily into your existing infrastructure. Once the application is finalized, its deployment takes just a few hours, unlike an on-site ERP.
Manage
Reduce ERP installation and maintenance costs
Custom web applications help minimize installation and implementation costs compared to an on-site ERP. The absence of ERP hardware and middleware reduces its pricing and makes SaaS maintenance costs predictable.

Custom SaaS software development eliminates unpredictable management costs. This advantage gives you a clearer view of your expenses and your ability to act on the business's operational needs.

Frequently
asked
questions
SaaS is a software distribution model hosted on the Internet and accessible via a third party's cloud.
SaaS solutions don't require local installation on company servers or user devices. They're hosted on a third party's servers, the SaaS ERP software provider.
Unlike on-site ERP solutions, the SaaS model is based on subscribing to a monthly or annual subscription with the service provider. No perpetual license purchase is required.
Application maintenance is managed externally by the SaaS service provider. Additionally, it's developed to meet modern businesses' needs. Scalable, its features adjust according to users' needs.
The on-premise ERP is a software model installed locally on a company's hardware and servers. The software is centralized on-site, but requires installing adequate infrastructure for maintenance, like an IT department.
SaaS ERP is a cloud-based professional application solution accessible via the Internet. The cloud is therefore external to the company and is managed by the ERP provider.
On-premise ERPs impose more installation and maintenance costs. SaaS ERPs make maintenance costs predictable and allow more effective action on the company's operational investments.
Software as a service offers several advantages for businesses.
It promotes rationalization and automation of operational processes through task automation. Collaborators can focus on higher value-added missions.
Additionally, the SaaS offer presents a financial advantage for professionals. Indeed, it's no longer necessary to install complex local infrastructure or call on an IT department. Application software is hosted on the provider's cloud who handles its maintenance.
The SaaS model allows businesses to benefit from powerful solutions 24/7 via an Internet connection without bearing the costs.
Our ERP agency offers custom SaaS solutions to meet each client's specific needs: SaaS accounting, personnel management, medical office appointment scheduling, etc.
Here are some examples offered by other SaaS software publishers:
Microsoft 365: Microsoft's productivity applications, available on the cloud.
Dropbox: an online data storage service that allows collaborating directly on documents.
Doctolib: a medical appointment booking application.
Salesforce: customer relationship management software.
Shopify: an e-commerce platform that allows creating and managing your online store.
The development cost of a custom SaaS (Software as a Service) solution is extremely variable. It's generally quoted from €10,000 and can easily exceed €300,000 for complex platforms (ERP, advanced marketplaces, business applications with real-time synchronizations).
The range essentially depends on the project scope and desired features.
Absolutely, yes, there is maintenance on custom SaaS software, and it's even crucial and essential to guarantee its sustainability and proper operation. Unlike software installed on your own servers (On-Premise), you don't have to manage the infrastructure, but the software itself needs to be maintained and updated.
Custom SaaS maintenance is mainly divided into two major categories:
- Corrective and Adaptive Maintenance (Mandatory)
- Evolutionary Maintenance (Strategic)
Hosting cost is a recurring expense (monthly or annual) that is rarely fixed. It operates on the 'Pay-as-you-go' model (usage-based payment). The cost depends on the actual resource consumption by your application.
