The Review
Feedback summary: 

Gulo delivered a system that both simplifies internal workflows and saves money via lower interchange rates for credit card payments. It has already saved $70,000 and will provide an ROI within one year. They worked seamlessly with both in-house employees and other third-party vendors. 


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 VP of finance for Dunbar Armored. We're an armored car cash transit provider that also offers outsourced processing for banks. In our money rooms, we physically process and count coin and currency for deposit. Money processing is our core business. 

Our ancillary services include a web system that allows customers to pay invoices online. We're not a major proponent of credit card use because our industry doesn’t offer cash discounts and the 2.5–3% interchange fees can add up quickly. We manage these payments very selectively. They account for less than 5% of our overall tender simply because of cost. Our returns are pennies on the dollar, so every transaction counts. Check and automated clearing house (ACH) payments are much more effective.


What challenge were you trying to address with Gulo?

Like any business, we needed an online portal to allow customers to pay by credit card if their contract requires it. We had a significantly outdated website that was hosted on very old server technology. We contracted with Gulo to create a new website with a PayTrace gateway. 

Our hosting company was going through some changes and highly recommended that we move to another provider. At that point, they couldn't promise they could relaunch our site if it ever crashed. 


What was the scope of their involvement?

Gulo designed and hosted our new website based on the wireframes we provided ahead of time. We didn't want to break away from the mechanics of our existing system’s customer experience, so they kept the UX simple. The payment gateway makes it easy to go online, look up open invoices, select ones to pay and check out.  It’s not meant for viewing anything in detail. We have other web portals for our customers to access copies of their bills. Gulo also works in conjunction with another company who manages interchange auditing. Level three processing minimizes the rate often to as low as 2% per transaction.

As the team automated processes, they built the new interface to update and refresh nightly. At midnight, the system automatically pulls payment information from accounts receivable into a file for our IT group to grab the next morning. The previous system’s user-driven updates required our cash-out person to initiate this process by manually refreshing the website.

The project lead carefully worked through all the details with our IT and finance teams to get the system up and running. My group and the cash-out and accounts receivable teams walked through and tested it. They provided feedback about what was missing or needed tweaks. 

What is the team composition? 

Zach (Partner and Chief of Technology, Gulo) was the project lead. He was on all our calls as we walked through the process and started testing the site.

How did you come to work with Gulo?

Our IT group got a referral to use Gulo. It might have been from the company we use for audits. 

What is the status of this engagement?

In July 2017, we started mapping out the project. We converted over to the new system in October 2017.


What evidence can you share that demonstrates the impact of the engagement?

Gulo helped us build a new system that gives us a much lower interchange fee. It saves us a good 70 basis points on $10-11 million worth of sales, which is about $70,000. I'm very pleased from a financial perspective. We'll see a return on our investment in less than a year. 

Internally, going through this process made our jobs easier. Having a much cleaner nightly cut off at midnight syncs up all the operations on the merchant end. Our engagement was a success. It has simplified work for our employees.

How did Gulo perform from a project management standpoint?

Gulo was excellent. The owner was always very helpful. We communicated through phone and email. 

What did you find most impressive about them?

Gulo delivered what they promised to. We’d used another provider who couldn't finish our project right. After that vendor's system went live, it had so many bugs we had to cut ties. During our second time around, we used Gulo, and it has worked out very well. 

Are there any areas they could improve?

I can't think of any. I haven't seen any bugs. We've only had 1–2 updates where customers made multiple payments late at night that weren't reflected correctly on the download report. After we submitted a help ticket, they were quickly able to remediate, research, and close out the transaction.
