Most IPTV Reseller Panel platforms assume every customer has one account. They don't. I've watched a British IPTV customer accidentally create three separate trial accounts with three different emails. He wanted to buy a subscription. He didn't know which email he used for the trial he actually liked. The reseller had no merge function. He had to manually transfer data between accounts. Took 45 minutes. The customer almost left twice.
What actually works is a panel with an account merge tool that combines MAC addresses, watch history, and payment records. Run a British IPTV duplicate account test through your panel. Create two accounts for the same person. Can you merge them? Does the panel preserve both payment histories? One reseller I know uses merge weekly—families, email typos, people who forgot passwords. His IPTV Reseller Panel handles merges in under 10 seconds. That's the difference between a frustrated customer and a relieved one. That said, many panels don't offer merge at all. Their solution is "delete one account and lose the data." That's not a solution. That's data destruction. Ask about merge before you need it. If the answer is "we don't have that," keep shopping.
