Our collaboration with Invictus Modern Dentistry began in June 2025. In the early stages of our partnership, it was Alex who contacted me. I really liked Alex. I did some research on him, and I found out that he is a dentist with a PhD, and his preparation work was excellent with very high professional standards. After he handed over the work to me, he immediately had Lucas get in touch with me, and from then on, all payment matters were handled by Lucas. They really liked our work, and our pricing was very competitive! However, the trust between us began to decrease due to delayed payments, which later turned into prolonged delays.

Looking back at our communication history, from the second package of our collaboration, collecting payments was never easy. Initially, Lucas requested that we settle the bill on the 10th of each month. This was quickly approved by our finance team because he is a dentist, and dentists are very protective of their reputations. However, what I didn’t expect was that, even with the agreed-upon payment date, Lucas would always delay payments for various reasons and excuses.

In fact, it wasn’t until the end of our partnership that I found out from Google that Lucas Silva’s real name is Lucas Lima, and he is an unlicensed dentist. The real Lucas Silva is someone else, and you can find him on Google.

At first, I was very understanding, thinking he was indeed busy. After that, when the doctors sent cases without detailed instructions, we would handle them as regular cases and use simple, standard procedures. The next three months were the most troublesome. I noticed an unusually high redo rate from Invictus Modern Dentistry. At times, the monthly redo rate exceeded 8%, and at its peak, it reached 27%. I immediately investigated the cause and found that several cases had been redone multiple times, even up to the third time. The reason was that the patients had high demands, which the clinic didn’t inform us of initially. We made the cases according to the standard quality, and the patients were not satisfied. The cases were sent back for remakes without marking them as redo cases or specifying what was wrong, until the second redo when they informed us of the issues. Anyone in the lab business knows that after one redo, there is no profit, let alone after two. Due to the lack of communication, we failed to complete several cases in three months. In September, Lucas also mentioned that he had two patients who had not paid. Of course, this happened later on.

What I want to express here is that for cases that were not handled properly, the lab does bear some responsibility, but the clinic also shares half of the responsibility. The clinic should not only focus on the business aspect and neglect the details after the order is placed. Our technicians cannot see the patients, but the doctors are the ones who understand the patients’ needs the most. A perfect case requires not only the ability of the technicians but also the doctor’s instructions and requirements for details.

Since September, Lucas has been saying that his company’s account had issues because of patient refunds, and they were unable to make payments. He asked us for more time. So, payment delays began, starting with one month, then two months, and eventually three months. In between, he made a few small Zelle payments, but they were so slow that it soon became three months of unpaid bills. The worst time came when payments were four months overdue. Then, our finance team intervened and restricted our shipments. From the end of January, we only sent Lucas a few urgent cases. A month passed, and Lucas was still paying very slowly. By the end of February 2026, even the November 2025 payments were not cleared. So, out of necessity, finance enforced a halt in shipments.

On March 12th, Lucas told me that one of his patients’ cases was urgent, and the patient would be leaving town next week, needing the prosthetics by Friday. I clearly told him that all his cases had been completed, and if he cleared all payments for cases before January, I would send out the package, and he would receive it by Friday for the patient. However, he refused. At that moment, I realized that perhaps the patient wasn’t as important to him.

(Additional note: I had suspected that Lucas might want us to waive the fees for patients who requested refunds, but we had already remade the cases at least twice, and there was no profit left. I had suggested that we could offer a 50% discount for patients who requested refunds, but he never responded to this proposal.)

He always apologized, citing company financial issues as unprecedented. However, this problem had prevented him from making normal payments for nearly six months. I don’t understand how he could still pay his employees or run the clinic. He had almost never fulfilled his payment promises, and this led to his most recent request for us to continue sending urgent cases, but his weekly payments were directly rejected by finance.

It has now been 5 days without a response to my messages. Last week, he promised to arrange a payment plan, but I still haven’t received any update. I checked, and there are still 19 cases left abandoned in our office, the earliest dating back to January and the latest from March. He hasn’t mentioned them again, so maybe he has sent the data to another lab.

I really want to communicate properly with Lucas to discuss the payment plan, but he doesn’t answer my calls or reply to my messages. In desperation, I have no choice but to record these matters in writing. I hope someone from Invictus Modern Dentistry can see this and contact me as soon as possible.
