This sounds like two Point of Sale software companies I used to interact with.

PCAmerica sold themselves to a credit card processor that was then also acquired, and the POS software has been frozen in amber the last 5 years (with the same terrible bugs). Their market share has collapsed since then, as software support has been outsourced to India and they cobranded with Heartland Payments.

The other POS company is still struggling to survive, they have a couple large accounts but they are all using the legacy codebase built atop VB6, and their C#/Angular.js rewrite is still missing most of the features they had 15 years ago, despite 4 full time developers working on it since 2015.

Admittedly, the latter company seemed like a series of unfortunate events. They bet on Index Payments (Started by some Googlers, bought to be scrapped by Stripe which told grocers nationwide that they were going to brick their payments), did not chase large volume accounts that could have funded more developers & support, and inevitably missed the mark by rewriting a large application and halting forward progress.
