Mobile App Dev for Home Improvement Company
the project
“They’ve solidified themselves as a top partner, and we plan to continue working together.“
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the CIO for a home improvement company; we sell roofing, siding, windows, gutters, and gutter protection services to homeowners in the US.
What challenge were you trying to address with Grey Chain?
We had faced delays with our mobile application while working with another service provider, so we engaged Grey Chain to build a functional sales enablement app. Our goal was to create a customized tool that provided our users with a consistent customer experience.
What was the scope of their involvement?
Grey Chain has supported us with mobile app development and UX/UI design initiatives. They started by conducting workshops and interviews with our team to gather the requirements. We also provided them with marketing materials to support the design process, including color schemes and logos.
Once they learned about our industry and business vernacular, they designed and built a new mobile application from scratch. They were responsible for creating designs, names, and icons for the new app. Since our existing app was built for iOS, the team also made the new version for iOS. We haven’t published it to the app store because it's proprietary.
The new version of our app is called HIRO, which stands for home improvement renovation options. Grey Chain built a CMS that organizes our product and pricing catalogs by market branch on the back end. They also embedded the app with all the capabilities a sales executive needs to sell a customer. The app holds measurements, product pricing, customer financing options, discounting functionality, and e-signature functionality. It also accommodates credit card payments for customers who want to submit deposits directly through the app.
Furthermore, Grey Chain integrated the app with APIs, which means that confirmed leads can reach our sales executives directly through the app. Our sales executives can access appointments and customer information via turn-by-turn navigation. Additionally, the app stores information from our call center regarding which products potential customers are interested in. They also embedded product presentations and videos within the app to provide potential customers with a consistent end-to-end flow.
Our sales executives used to bring boxes of product samples and literature to appointments, but the team digitized those resources and embedded them into the app. Furthermore, the app also features a leaderboard that enables sales executives to judge their performance against their peers. They can also use the filter views to review the past month or 90 days.
Now that we’ve launched the new version of the app, Grey Chain has been working on expanding the functionality. For example, we recently launched a bath and interior division, so they’ve scheduled a work stream to add those capabilities.
What is the team composition?
We’ve worked with 15 people from Grey Chain: four iOS teammates, four architecture and backend teammates, one dedicated testing resource, one design resource, three project management resources, and a PowerBI resource for reporting.
How did you come to work with Grey Chain?
We found them through a referral.
How much have you invested with them?
We’ve invested roughly $300,000 in the partnership.
What is the status of this engagement?
They won partner of the year for their work in 2022 and early 2023. 5⭐️ experience!!
What evidence can you share that demonstrates the impact of the engagement?
Grey Chain has significantly improved our mobile app's UX/UI design and flow. Our previous app lacked API capabilities, so it didn’t function how we needed it to. For example, when customers wanted to submit payments, they had to call our office, provide their credit card information, and wait for us to enter it into a system. Now, we can accommodate payments via the app, making the process seamless and clean.
Furthermore, the app has seen an outstanding internal adoption rate, facilitating 13 months of record sales performance and growth. Grey Chain’s efforts have entirely transformed our sales process without skipping a beat, which is a huge testament to them.
How did Grey Chain perform from a project management standpoint?
Grey Chain has been an outstanding partner throughout the development process, and we’ve built a phenomenal relationship. Although the team is offshore, they’re just a phone call away. They’ve gone above and beyond to support critical business disruptions, which we appreciate.
During the development phase, they organized work sprints around the UI and API layer. We used Excel and Jira to manage development tasks.
What did you find most impressive about them?
Grey Chain has talented designers with robust industry knowledge. Working with them has been easy, and I’ve been most impressed by their flexibility and warmth. They’ve solidified themselves as a top partner, and we plan to continue working together.
Are there any areas they could improve?
No, I’m 100% satisfied.
Do you have any advice for potential customers?
What are you waiting for, have a discusson!
