Custom Invoicing Platform for Advertising & Marketing client in Czech Republic

Client Story

A Prague-based advertising and marketing agency, prides itself on delivering innovative campaigns for clients across Europe. As the company grew, its manual invoicing processes became a bottleneck, leading to delays, errors, and fragmented client communication. The Founder & CEO, recognized the need for a tailored solution to automate workflows, centralize financial data, and enhance scalability.

In April 2024, the client partnered with Facile Technolab to design and develop a custom invoicing application that aligned with their unique operational needs. The goal? To replace outdated spreadsheets and disjointed tools with a unified platform that could grow alongside their business—and even become a marketable product.

Business Case

The client required a custom invoicing application to:

Automate manual workflows for invoicing, client communication, and financial reporting.
Centralize data for contacts, billing details, and invoice templates.
Enable scalability by integrating third-party tools (e.g., email services, accounting software).
Reduce human error and improve compliance with standardized processes.
Pilot a subscription-based SaaS model to monetize the platform externally.

Challenges

Time-Consuming Processes: Manual data entry and invoice generation consumed hours of staff time weekly.
Fragmented Systems: Client data, billing details, and templates were scattered across spreadsheets and emails.
Scalability Limitations: Existing tools lacked flexibility to adapt to growing client demands or new integrations.
