Frequently asked questions about MAIN-TOOL

What is MAIN-TOOL?

MAIN-TOOL is software for mapping maintenance-relevant processes in Microsoft Dynamics 365 (Business Central, NAV). As a Microsoft certified product, MAIN-TOOL is fully integrated in Microsoft Dynamics. In the maintenance processes, MAIN-TOOL can access the master data e.g. from the modules purchasing, warehouse, resources or projects and use this for an efficient organization of maintenance.

What advantages does the MAIN-TOOL maintenance software offer?

With MAIN-TOOL, existing master data at companies with Microsoft Dynamics 365 can also be used for maintenance. The documentation and handling of the maintenance processes on different and parallel platforms such as Microsoft Navision or Business Central as well as Excel, Word and Outlook for communication can be omitted.

All technical objects and associated maintenance processes can be mapped in MAIN-TOOL via cloud, Windows client, web client or mobile client in the form of a MAIN-TOOL app. In addition, software-supported maintenance enables a great deal of optimization potential through the reuse and further use of existing data sets, ensures compliance with quality requirements, improves system availability, creates transparent cost control and simplifies maintenance.

MAIN-TOOL also supports e.g. spare parts management, materials management, resource management, technical purchasing or contract management for service or maintenance contracts.

Finally, MAIN-TOOL draws on more than 35 years of “operating experience” and strong networking for the development and continuous adaptation to the requirements of our customers.

For which companies is MAIN-TOOL suitable?

MAIN-TOOL is used with the established ERP standard software Microsoft® Dynamics® Business Central® in more than 100,000 companies across industries in 54 countries worldwide. And for good reason: It’s easy to use. MAIN-TOOL can be quickly integrated into existing systems. Certainly with you too. Take a look at our references.

How does preventive maintenance work with MAIN-TOOL?

Preventive maintenance is maintenance at set intervals in order to reduce the risk of system and machine failure. By setting up a schedule, MAIN-TOOL calculates the suggested date based on the technical object. MAIN-TOOL also simplifies the entry into demand-based maintenance (condition-based maintenance), which suggests the inspection or maintenance at the given point in time with easily configurable performance data acquisition and definition of individual trigger criteria. Last but not least, MAIN-TOOL also enables the further development of predictive maintenance through the use of artificial intelligence in cooperation with WAGO, such as the WAGO connector, which carries out permanent condition monitoring based on algorithms and then proposes an appointment in MAIN-TOOL triggers for inspection or maintenance at the right time.

The proposed date can then easily be converted into a work order and goes through the order planning, execution and completion notification, optionally supported with work instructions and checklists to ensure the quality of the execution.

All of this enables you to prevent failures in good time, reduce expensive downtimes and effectively lower maintenance costs.

How does the introduction of MAIN-TOOL work at the customer?

You tell us what you want to use MAIN-TOOL for. We explain the possibilities to you and define the package of requirements together with you in an analysis workshop. You will then receive a qualified offer from us, e.g. consisting of software, set-up support and training for the desired elements. An experienced project manager will be at your side until the successful introduction of MAIN-TOOL in your company. You then have access to our first-level support and customer portal, where we provide current information and instructions for download.

On which platforms can MAIN-TOOL be provided?

When deploying, you can choose between a server installation or operation in the cloud. You can then work with MAIN-TOOL on both stationary and mobile clients. An app is also available with a range of functions tailored to mobile maintenance.

Which MAIN-TOOL Edition and Microsoft Dynamics Version are required for the MAIN-TOOL Mobile App?

The MAIN-TOOL Mobile App is included from the MAIN-TOOL Easy Plus Edition.

At least Microsoft Dynamics 365 is recommended for using the MAIN-TOOL Mobile App, but the MAIN-TOOL Mobile App can also be used from Microsoft Dynamics NAV2017.

How can MAIN-TOOL change maintenance in a positive way?

MAIN-TOOL simplifies the monitoring of your machines, systems and vehicles and supports you with appointment suggestions at the right time. Processes are digitized and paperless, everyone involved is always up to date.

Maintenance is becoming more transparent, comprehensible, plannable, mobile, and easier. Maintenance made easy – with MAIN-TOOL.

What does the MAIN-TOOL maintenance software cost?

With an annual contract, the monthly rental of the software per user is € 99 *.
With a monthly rental without an annual contract, it is € 119 * per user.
(* plus statutory VAT).

With MAIN-TOOL, cost transparency begins with the purchase. Find out now under prices what an implementation of MAIN-TOOL would cost.

Can MAIN-TOOL also work across departments?

Yes, because, on the one hand, any department structure can be mapped and thus users and orders can be assigned to a desired department level.
On the other hand, MAIN-TOOL is fully integrated in Microsoft Dynamics 365, which means that all users for whom MAIN-TOOL is licensed can also work with MAIN-TOOL and edit data. In addition, every licensed Microsoft Dynamics 365 user has read rights for MAIN-TOOL.

Is MAIN-TOOL certified by Microsoft?

Yes, MAIN-TOOL is certified for Microsoft® Dynamics® Business Central® (and its previous versions) and is therefore one of Microsoft’s recommended software solutions for technical management and maintenance.

Can data be transferred from other systems?

Yes, it is possible to migrate data from other systems. However, a distinction must be made between simple lists and complex tables with multiple references. The effort for data migration is based on this, e.g. via Rapid Start.

Can individual software requirements be taken into account?

As the developer of MAIN-TOOL, we know how to effectively implement the individual requirements of our customers and to integrate them into the possibly more comprehensive processes of Microsoft Dynamics 365 with additional modules from Microsoft partners.

We therefore check the feasibility of each adjustment request in detail and determine the effort required in order to provide the customer with a good basis for decision-making based on the cost-benefit ratio.

How many MAIN-TOOL licenses are required?

Every employee who will work with MAIN-TOOL needs an assigned user license. There are two license types to choose from:
The “Essential User License” enables all writing and booking transactions. Alternatively, there is the “Team Member License” with restricted rights (writing, no booking processes).
