Show HN: I made Sundaysub to help small startup create invoice for free (sundaysub.com)

Hello HN, I'm Vinz.

Based on my experience running a small design agency based on recurring monthly, i found a little issues with invoicing and subscription tracking for my clients, i was counting and create booklog manually on my notes and started to get a little headache with those repetitive works.

So i made Sundaysub, a little platform for me to create my invoice and save it easily. I don't have to create the product or write what product to deliver for several times, i can save it there. Also, i tried to improve the UI inn a POS-style format. On the left you can get lists of your products services, and you can record it in the order summary and complete the transactions.

I thought this is a helpful app that i've used personally for my agency, now i tried to open this app for free on public. Hope this would be helpful.
