1. Mesa Revenue Partners

Website: https://mrpcollects.com/colorado-commercial-collections-agency/
Address: 360 S Garfield St #400
Contact: +1 (303) 696-3910
Hours: Monday – Friday, 6:00 AM – 4:00 PM
Mesa Revenue Partners is a top choice for handling big B2B debt collection, especially when speed and results matter. They use a worldwide network of attorneys, so they can track down money even if someone has skipped town.
One client we talked to said they successfully recovered a large unpaid supply contract for their company. She added that they even found hidden property no one knew existed.
I love their online portal, which lets you check your case progress in real time, so you don’t have to keep calling for updates. Plus, they only charge if they recover your money, so there’s not much risk.
Just keep in mind, they work only with business-to-business cases. This means if your debt is small or personal, they can’t help.
Their in-depth investigations can also take a bit longer than sending a simple payment request.
Customer Reviews
He has been great to work with
I researched and vetted several collection agencies for my company to begin using. We chose Mesa Revenue Partners due to the relationship built with Jon Milstein. He has been great to work with and has done a fantastic job collecting payments that my team has spent a lot of time and effort chasing down. We will continue to send difficult accounts to Jon/Mesa as they have proven to be successful in this arena.

2. Greenberg Grant & Richards

Website: http://ggrinc.com/
Address: 8301 E Prentice Ave STE 316, Greenwood Village
Contact: [email protected]
Hours: Monday – Thursday, 7:00 AM – 5:30 PM, Friday, 7:00 AM – 3:00 PM
Greenberg Grant & Richards stands out for their strong negotiation skills and fast results in collecting debts.
Their in-house legal team is huge, so if regular talks stall, they can quickly move to legal action without missing a beat.
They also offer first-party services, which basically means they can take over your billing department to keep things smooth and professional.
We spoke to a client from a construction company who was really impressed by how efficiently they handled a complicated mechanic’s lien.
However, their focus is usually on bigger accounts. If you’ve only got a small invoice, their high-powered service might feel a bit much.
Customer Reviews

They have been able to get the answers we needed when we thought we were at the end of the road. In difficult situations like Collections, GGR is highly recommended!

3. Aurora Collection Bureau

Website: https://www.acbcollection.com/
Address: 2442 S Downing St.
Contact: [email protected]
Hours: Monday – Friday, 8:00 AM – 4:00 PM
Aurora Collection Bureau has been helping local businesses and medical offices in Denver for more than 50 years. Because of that, they already know their way around healthcare and consumer debt collection.
We like that they use advanced skip-tracing to track down people who seem impossible to find, which makes a big difference for medical offices. They also make sure everything stays HIPAA compliant.
Plus, their reports can connect straight to your accounting software, so you don’t have to keep nagging your accountant to handle annoying manual entry.
We chatted with a clinic manager who said the staff gives a personal touch that’s hard to find anywhere else.
Sadly, they’re not set up for tricky international cases. Also, their office closes a bit early and is closed on weekends, which can be frustrating if you need weekend help.
Customer Reviews
We are grateful to be working with Aurora Collections Bureau
Everyone here is easy to work with and very nice. They are very helpful and have even given me advice on how to handle clients, even before I place them in collections. As a company, we try to avoid collections as much as possible, but when we do have to use collections, we are grateful to be working with Aurora Collections Bureau!

4. Agency of Credit Control Inc

Website: https://www.getitpaid.com/
Address: 2014 S Pontiac Way
Contact: +1 303-757-5147
Hours: Monday – Friday, 8:00 AM – 4:30 PM
Agency of Credit Control Inc makes a real difference with their smart pre-collection program that motivates people to pay before things get stressful.
This early approach uses professional and friendly communication, so you can avoid the hassle of aggressive collections.
We’ve heard from clients that the staff is all about staying non-confrontational, so there’s much less worry about legal complaints coming back to your business.
They’re also trusted with big accounts from utility companies and property managers, which shows they can handle serious volume.
Plus, many clients find it helpful that their success team offers training to help boost their own credit policies.
One thing to remember is that the pre-collection letters do have an upfront administrative fee, whether they work or not. And because they’re a bigger operation, you might not get that small, personal feel some boutique firms offer.
Customer Reviews

5. Asset Recovery Inc

Website: https://assetrecoveryinc.com/
Address: 910 16th St Mall, Suite 624
Contact: +1 (800) 815-5032
Hours: Monday – Saturday, 9:00 AM – 6:00 PM
Asset Recovery Inc is a boutique agency that comes through when you need help with tough cases like judgment recovery or unclaimed funds. They focus on collecting court-ordered payments that have been ignored for years.
They’re also skilled at finding foreclosure overages and handling judgments on a pure contingency basis, taking care of all the legal filing costs themselves.
This makes them a solid choice for those hard-to-collect cases, especially when bigger agencies have already given up.
But since these cases can be tricky and involve a lot of legal work, be prepared for the process to take months, sometimes even years. Also, being a smaller firm means they can’t take on thousands of tiny cases at once.
Customer Reviews
