FAQs about weclapp ERP for Solar and Photovoltaic Companies
How does weclapp support solar/PV companies in their day-to-day operations?
weclapp helps you structure and efficiently manage the daily operations of your solar company. You can create quotes, sign contracts, and send invoices electronically – all within a single system. With project management, you can keep track of your resources, tasks, and deadlines and coordinate your team effectively. Inventory management also supports you: purchases, suppliers, returns, and various warehouse areas – including order picking – are digitally mapped. A mobile warehouse app ensures that your warehouse staff can work directly on-site. Additionally, documents can be sent via the software, and maintenance contracts as well as financial matters can be managed centrally.

weclapp offers comprehensive support for the structured planning and execution of charging station installation projects.
