Low-Code Flutter CRM Application for Field Sales Operations

Low-Code Flutter CRM Application for Field Sales Operations

A mid-sized industrial supplies distributor based in Warsaw, Poland, managed a 70-member field sales workforce operating across multiple cities. Their sales agents relied on spreadsheets and manual forms to record visits, collect lead information, and track follow-ups. To modernize field operations rapidly without long development cycles, the firm partnered with our team to build a low-code, cross-platform CRM application using Flutter and visual workflow builders.
