I had an excellent experience working with ProsperSpark on a custom Excel audit tool. From the initial discussion through delivery, their team was highly responsive, organized, and easy to work with. They quickly understood the complexity of the project including weighted scoring, reporting, and dashboard
requirements and translated it into a clean, functional solution.
What stood out most was their turnaround time. They delivered a strong first draft very quickly and were proactive in walking through the tool, explaining functionality, and identifying areas for refinement.

The final product significantly improved our ability to analyze audit results, with automated data processing, clear summaries, and strong visual reporting. It’s clear they focus on building practical solutions that reduce manual work and improve accuracy.

Overall, I would highly recommend ProsperSpark to anyone looking for expert Excel support, especially for complex or time-sensitive projects.

We have been working  with ProsperSpark for over a year. They have been instrumental in helping us get our Airtable dashboard to where it needs to be. They are attentive and always available to assist. I want to shout out Jessica McMullen specifically who has been absolutely great to work with in every way.

I chose Prosper Spark because I needed help on an excel project that others had not succeeded.  They did everything as expected, provided good service, treated my hours with care, and made sure I wasn't billed if a mistake was made on their end (which was very important to me).  Ross was excellent in his response and solutions.  Thank you for the work you did for me!

Working with Prosper Sparks has been one of the most impactful decisions I’ve made for my business. From the very first conversation, their team brought not only technical expertise but also genuine care, curiosity, and a deep respect for the vision I had. They didn’t just offer automation—they listened, asked the right questions, and helped me reimagine what was possible.

Before Prosper Sparks, I was juggling too many manual processes, patching together systems that didn’t talk to each other, and spending valuable time on tasks that weren’t moving the needle.

What stood out most was their ability to translate complex systems into simple, actionable solutions tailored to my unique needs. They didn’t push a one-size-fits-all approach—they built with me, not just for me. Every step of the way, I felt supported, empowered, and genuinely excited about the future of my business.

Prosperspark has helped us several times over the years with some complicated workbooks our company uses.  They are always prompt, professional, and upfront on pricing.  Would definitely recommend!

I reached out to Prosperspark to help me create a spreadsheet to help track budgets and financials for a commercial general contractor.  Erin and Jessica took on this role and worked with me over the course of a few months to deliver a workbook that not only is easy to use, but saves me a lot of time with the quick buttons that are integrated to create PDF's and save them in Onedrive.  They listened to what I needed, provided some ideas and direction and the whole experience was a lot of fun.  It has made my day easier and will help my company save time and money.  Thanks.

I've been working with Jessica at Prosper Spark for a couple of months now.  She's been amazing.  There are times when I've wanted our project to report certain information and didn't quite know how to set it up or explain it and she's interpreted my jumbled speech into exactly what we've needed. Professionalism and expertise are beyond reproach. I will definitely go back to her if another project comes along!

I've had the absolute best experience. They have been easy to communicate with, and were very clear about what to expect and when to expect it. And they delivered. They made automations for me that saved me hours of time each week.
