Choosing the right firm for your Excel Add-in development is critical since it makes all the difference in the success of your project. Hundreds of entrepreneurs enter the market with theaim of success, making it difficult for clients to evaluate which firm is the best for their bespoke software development.
When you consider outsourcing a software project, you often wonder:
Thus, doing extensive research before choosing one is essential.
Now what if I told you that you are just one step away from finding the best firm for your Add-ins development? Here is the blog that will walk you through the key questions to ask before hiring an Excel add-in developer. Let’s get started.
Whether you choose to outsource your Add-in project or hire Excel Add-in developers, it is always necessary to do thorough research and ask pertinent questions in order to save time and get the desired outcomes.
Here are the top questions clients should ask developers before hiring them for business.
“It always makes sense to start with basics. One of the first questions you should ask is about the order of operations used in Excel formulas. This tests the applicant's foundational knowledge of Excel along with their mathematical thinking. After that question is answered, you want to ask them something more specific that tests how deep their knowledge is. You might ask about using a pivot table or VLOOKUP to see if they know about either of those.” - says Josh Snead, CEO of Rainwalk Pet Insurance
In order to make an informed decision, it is important to consider professional viewpoints. Let’s look at the valuable insights of various experts about the questions to ask before selecting a business and the reasons behind each.
Nikita Sherbina, the Co-Founder & CEO at AIScreen says – “Try asking these questions to the developer:
- This question assesses the developer's expertise and proficiency in creating Excel add-ins, indicating their familiarity with the development process, understanding of Excel's capabilities, and ability to deliver quality solutions.
- Reviewing the developer's portfolio allows you to evaluate the quality, functionality, and design of their work. It ensures their style aligns with your requirements and showcases their ability to deliver successful solutions.
- Understanding the developer's technical skills and preferred programming languages (e.g., VBA, JavaScript, C#) provides insights into their versatility and compatibility with your project's requirements.
- Compatibility is crucial to ensure the add-in functions seamlessly across Excel versions. A skilled developer should have a strategy to address compatibility challenges and ensure a smooth user experience.
- Check if the developer has experience integrating data from external sources or APIs. They should efficiently handle data retrieval, manipulation, and synchronization with Excel.
- A rigorous testing process identifies and resolves bugs or issues before final delivery. Testing ensures the add-in functions reliably, enhancing user satisfaction and minimizing problems.
- Ongoing support addresses future updates, bug fixes, or compatibility issues. A developer offering reliable post-development support ensures the longevity and improvement of your Excel add-in.
Asking these questions helps evaluate an Excel add-in developer's expertise, track record, technical skills, compatibility strategies, integration capabilities, testing procedures, and long-term support. It enables an informed decision when hiring a developer who can deliver a high-quality and effective Excel add-in tailored to your needs.”
Before hiring Excel add-in developers, asking the right questions is crucial to ensure you make an informed decision. Here are some essential questions to consider:
