Projectmanager Movares

“Movares has outsourced its recruitment process to Solveo. Solveo is part of the Movares Group and uses the recruitment system Otys to support their process. At Movares we use AFAS for our ERP processes. We were looking for a partner who could help us realize the interface between Otys and AFAS so that data no longer had to be entered manually. Solid Online and Conclusion Afas Solutions (CAS) have realized this interface for us. The collaboration between CAS, Solid Online, Solveo and Movares has gone well. The interface is working great!”

IT Information Analyst Kramp

"Due to the continuous further digitization of our HR processes, we are very happy with the interface via Solid Online, making manual creation and/or changes a thing of the past for our large group of temporary workers. Besides the time savings both on the side of Kramp and of temporary employment agencies, this also results in a quality improvement, which means that we can involve temporary workers even closer to our organisation. Furthermore, this opens the door to connect other integrations, countries and employment agencies. By this, Workday is stabilizing its position as our leading HR system.”

"We chose Solid Online's CYF Connector because it enables us to quickly and easily check contract data and time registration for correctness and completeness. Until recently, revenue recognition was a labour-intensive exercise, but fortunately this is a thing of the past thanks to the CYF Connector. The automated booking from Carerix to Exact Online is also very reliable and fast. The implementation went very accurately and smoothly thanks to a very pleasant and professional collaboration with Solid Online. We are already thinking about extending the CYF Connector to other systems we use, such as Nmbrs."

“We offer our customers a Future Fit IT landscape in which reliability, sustainability and agility are central. We are convinced that this is possible only by offering maximum functionality and freedom of choice for specific functionalities. In practice, this means that we optimally integrate additional specialized software where desirable for our customers and thus offer maximum business value across the entire chain. Solid Online is one of those partners with whom we make this possible ”.

Senior Application Manager Teamflex

"Almost everything is done digitally nowadays, but communication between different software packages sometimes still seems to be very difficult. Solid Online offers the solution and has helped us establish an interface between Otys and HelloFlex. Through this interface, candidate, customer, and contact persons are automatically sent to Helloflex and even a contract in draft status is created. This saves us a lot of time, but the most important thing is that there are no mistakes at all in the process. During the project we were guided by Richard Baas. His knowledge of the different applications and the staffing industry contributed to a successful implementation."

"Solid Online has created a nice interface. With thanks to the great assistance and support of Martine. Nothing is too much to ask. Because of her expertise and quick actions, we can proceed quickly when we get stuck. It is a nice experience to set up an interface together which will now benefit us a lot. For example, we are currently setting up a whole new process within the organization. This ensures more efficient work. We have now finished up the first phase, on to the next!"

“Thanks to Solid Online we have been able to create an interface between Freepack and OTYS. Now we can transfer candidate data, customer data and placement data from OTYS to Freepack. This will save us a lot of valuable time. During the process we were well guided by Richard Baas, who I would like to thank for all the time invested in the project. Because of the differences between the programs, we ran into all kinds of problems that were eventually resolved, with this beautiful interface as the result.”

“The collaboration between Solid Online and Graydon is a perfect match. Both at Solid Online and at Graydon we are busy with data all day and therefore we speak the same language. Solid Online is the missing link between the Graydon database and all possible software packages in the temp agency industry. ”

“Partnerships in the software landscape can sometimes be very complicated. This is not the case when both propositions perfectly match each other. From Bullhorn we provide an excellent documented API where Solid Online knows how to deal with perfectly. They act accurately, say what they do and do what they say. This leads my team to bring Solid Online to the table of our customers, without us having any concern in it. They are resolute in dealing with the integration needs of our customers, of which I experience that the demand for integration of the different software tools has increased significantly.”

We want to thank Martine very much for her endless and enormous efforts the last few weeks.

“With this interface we no longer have to update everything manually and there is always a connection between our client’s planning- and time registration on the one hand, and our salary- and staffing software on the other. It saves time and reduces the chance of errors. We are happy with it!”

Marnix van den Berge | Partnership - OTYS - ConnectYourFlex - Solid Flex Solutions
Marnix van den Berge
Senior Account Manager OTYS

“The collaboration with Solid Flex Solutions makes it easier for us, and therefore also for our clients, to connect with back-office packages. Thanks to the interface of the ConnectYourFlex platform, it will no longer be necessary to build, we merely need to connect. That is much more efficient. Building an interface can sometimes take a few months. This is now much faster with Solid. Apart from that, it opens the door for us to multiple connections with other packages, without having to build each one ourselves. And best of all, this is a two-way street, so that the most important data centrally in our system can be made available to the user.”

"ConnectYourFlex gives us the opportunity to digitize the timesheet output and invoices for practically every customer. We set up the transforming for customers in no time. Complex billing issues are quickly solved. With the recipe settings in ConnectYourFlex we can easily define exceptions per customer.

In addition to the standard staffing processes for timesheets and Invoicing, we have recently invested in optimizing the intercompany and freelance process together with Solid Online. By generating and sending invoices on behalf of the freelancer and intercompany party, we have been able to make a big step. In terms of content, the invoice corresponds to the specified hours and so it can be processed fully automatically. This allows us to quickly generate invoices and most importantly, pay them!

By implementing ConnectYourFlex we have implemented flexibility as a standard!"

Erwin Haselbekke
Product Owner Billing & E-services USG People

"With ConnectYourFlex we flexibly arrange our processes for digital hours and expense processing. Whether it is about XML timecards via a web service or a supplied Excel hour list by mail, we can implement it all ourselves quickly and effectively. Digital wage processing is a piece of cake after this. We have also taken major steps in the field of digital invoicing. We are now able to meet the wishes of our customers. This is because we can now dynamically deliver different forms of XML and PDF invoices. We are no longer dependent on standards, but we are flexible in our options in this area. In short, ultimate flexibility to the outside world but unified and standardized for your internal business processes!"
