We Develop Custom Web Applications for Businesses That Are Enterprise-Reliable and Startup-Affordable

For over nine years companies have been outsourcing their web app development projects to us.
Most of these clients have remained loyal to the Greenice team to this day.


Our apps are often designed to store and process extremely valuable and sensitive information for our clients. So, we go to great lengths to ensure security at all levels, such as setting user roles with various access levels, IP protection and encrypting sensitive data, among other measures.


Most likely your business is constantly growing and evolving, so to be effective, the tools that you use should also be able to grow with you. We ensure scalability of our solutions by striving for the cleanest and highest-quality code possible, so your app won’t fall apart when you decide to add a new feature or two.

In Real-Time

In case you need an app for an ongoing business, or you want to upgrade a system you are already using, we have experience in planning and executing development processes in a way that will lead to minimal to no disruptions to your daily work.

Lead Management System for Financial Services

Our client, an Amsterdam-based factoring services company, needed to automate the process of capturing, filtering and classifying leads, as well as follow-up emailing and assigning leads to creditors. We built an internal system and integrated it with the existing website.
System features:

  • Capturing and storing lead profiles: the prospects enter their details themselves into the online form on the website; the system stores and classifies the data.
  • Capturing and storing profiles of factoring companies.
  • Matching leads to factoring companies: the system automatically matches clients to creditors on the basis of profile details.
  • Automated emailing: the system generates appropriate emails to clients and creditors with notifications and other relevant information.

Field Service Management System for Locksmith Company

We have built a system that captures customer information, processes orders, accounts for affiliates, and provides statistics and analysis.

  • Order processing: besides capturing client data during a call, the system also assigns jobs to appropriate technicians and automatically notifies technicians about jobs with SMS.
  • Affiliate marketing: partner commission is automatically calculated and transferred to the accounting system.
  • Integrations: the system is integrated with the company’s call center (Asterisk), accounting system (Sage), Google AdWords and PostcodeAnywhere (for address validation).
  • Statistics and analysis: includes a statistics module for tracking and analyzing conversions, as well as effectiveness of marketing efforts.

“Our company is absolutely satisfied with the way Greenice completed the project. It had a positive influence/effect on employees’ KPI, because the new system became faster and dependable, and now it totally conforms to the needs of each department. Since the new system has been implemented, we have started to create a new product: a partners’ engine called Satellite, which can help us to automate business processes between us and dozens of our partners, so our company’s income continues to grow.”
