Reviews about our company

David McGuire

I can only say - exceptional customer service, a quality outcome and I look forward to engaging SoftSolid in the future.

We asked for some custom work to be undertaken to suit our needs .... and the speed of delivery was excellent. Importantly the custom work was exactly what we needed.

It was nice to have a developer understand immediately what we wanted and then produce an excellent result - quickly and without fuss.

I will certainly be using SoftSolid again. Thankyou.

Highly recommend.

We cooperated with "SolidSoft" on the implementation of a new form of delivery - "Paczkomaty". Our store has a lot of custom changes. Often standard add-ons do not work properly after installation. They require adaptation to our system. Everything went quickly, smoothly and without much hassle.

The cooperation with SoftSolid during the implementation of the Baselinker module to our online store was extremely successful and professional. The team of specialists demonstrated in-depth knowledge of the Baselinker system and its integration with the Store Builder platform. Their support and advice allowed us to effectively implement the module, which significantly improved our sales processes and warehouse management. Thanks to the automatic data synchronization between Baselinker and our store, we gained full control over stock levels and product prices. This allowed us to avoid discrepancies in data and optimize our logistics operations. The SoftSolid team proved to be extremely helpful at every stage of implementation, providing professional technical support and adapting the solution to our individual needs. The implementation of the Baselinker module brought us significant business benefits, including increased operational efficiency and improved customer service. We highly recommend cooperation with SoftSolid to anyone looking for professional support in the integration of e-commerce systems. Thank you!
