  • New features implementation

Need to upgrade your custom CRM software?   As your business grows and evolves, you may feel that your current CRM solution does not meet your needs, or even slows your business down.  Allow us to redesign the existing functionality to develop and integrate the missing features into your system that will reinvigorate your present system, making it modern and competitive. 

  • Data migration to CRM 

Does your current system fail to keep up with today’s business? But at the same time, you cannot simply move for another CRM because your current system stores tons of valuable data?   Before migration, we first make sure that the existing data is updated, cleaned, and restructured if needed.   Next, we will extract and migrate all data from the existing system or systems into a newly created CRM. By designing an accurate data map, we will migrate each piece of information to the corresponding position in the new system, preserving all connections between the current system and the new platform. After migration, we’ll make sure everything was transferred correctly and nothing is missing. We will check that integrations with third-party applications are still viable in the new CRM solution.

  • CRM integrations

Need to exchange data with other company applications and third-party provider systems? Our development team is highly experienced in API development, and integration between different software — namely accounting systems, marketing automation, calendars, websites, social media, and team communication tools. We will link your CRM application to other solutions that provide API, thereby creating a seamless and secure data exchange.  We integrated the CRM of a large U.S. cosmetics company with their inner ERP and call center. This integration allowed the company to automate and speed up its order management system and increase sales tremendously.  

  • CRM modernization

Is your current CRM too slow? Revitalize it for better efficiency!  Legacy code is one of the most frequent reasons for low performance and security problems. Long-lived CRM solutions need periodic code-refactoring and migration to newer technologies.  Trust us to migrate your solution to the newest version of the PHP framework. We have already helped many clients increase performance, enhance security, fix old bugs, integrate new services, and facilitate future CRM improvements.

  • Mobile CRM development

Is your CRM solution going to be used by sales representatives or specialists who often work “in the field"? We will develop a mobile version of your CRM that will perform superbly on all devices. The mobile app will enable your employees to access necessary customer data and manage it in real-time from any location.

5 Benefits of Custom CRM Development over Off-the-Shelf Solutions

Should you build your own CRM or buy a ready-made solution? Here are the key reasons to choose a custom CRM:

  1. Uniqueness. A custom-built solution is 100% tailored to your unique business needs and you do not have to compromise.
  2. Flexibility. As your business evolves, it will require new features and modifications. A custom solution gives you absolute freedom.
  3. Security. You never know how and where off-the-shelf solutions store your data. Nor can you be certain who has access to it. With a custom solution, you can be sure that the code and access to the database belong only to you. When we implement custom solutions, we follow the latest security practices and use the most reliable cloud technologies.
  4. Scalability. A custom CRM is ideal for companies of all sizes, especially for small businesses that quickly evolve. As the number of users grows, the off-the-shelf solution may be inadequate. We plan the architecture of every custom CRM with future scalability in mind.
  5. Cost-effectiveness. With custom-created solutions, there is no need to pay monthly fees. Moreover, ready-made CRMs include features you do not need. Therefore, you end up paying for something that cannot be removed. Once built, a custom CRM will stay with you forever, needing only minor updates. Thus, in the long run, a custom web-based CRM will save a lot of money.

Featured Projects

No Cowboys: Legacy CRM modernization

NoCowboys is a tradesmen marketplace from New Zealand. We refactored the legacy code, created a new CRM, established a multi-layer protection system, and switched to a new search engine. The website performance increased dramatically; we also made it easier to implement new features and improved site security.

CRM for Factoring Company

Our team developed a custom CRM for a European financial platform that aggregates more than 20 factoring companies. The profiles of Leads and Prospects are easily managed using the CRM. The solution optimizes the company’s efforts by capturing leads automatically, filtering, classifying, and matching them to creditors. As a result, the customer service was streamlined while decreasing the workload on employees.

CRM for an Employee Assistance Provider

We implemented a custom CRM for an Employee Assistance Provider which provides workplace talking therapies. All data that had been stored in Excel was migrated to the CRM. The main features included the treatment plan, appointment scheduling, invoice management, and reporting. The system considerably reduced the administrative routine and enhanced the security of patients’ sensitive data.
