I know exactly what you mean. I've been using Paybis for my SLP to PHP conversions for a few months now and it's been working well. The process is pretty straightforward – you send your SLP, they convert it, and you can withdraw the PHP to your bank account or e-wallet. The rates are competitive and they show you the final amount you'll receive before you confirm the trade, which is the most important part. You can check the current rate and process directly on their slp to php page. It's definitely saved me a lot of time compared to other methods.
