I duly Regret first for being sounding stupid. Better have office installed for maintaining records by use of excel sheets for maintaining records of daily customer. Use account software too for knowing your cash flow as well as expenses, to help you better with your funds management. You need to have Microsoft access encoded program to be prepared by it geek for same.

Now coming to your basic question. It sounds odd, but have better high speed Internet and update pc seperately, bcos it sounds odd but this is the best solution overnight, you need to uodate via platforms you installed steam / epic / origin. Nvidia Geforce Experience/ amd adrenaline to update gpu and offourse Windows update. I said same bcos to have automated ones you need to go through only paid programmes only. So it may sound absurd, but update manually individually when you start cafe, is tedious one, so do it every 15 days. Rest small updates will be carried by gamers as they arrive. You need to be aware on your pc when you start cafe, whether any new update released fpr any game, then you need to come early and do update that game 4 pc at once one time. It saves you hurdles.

Business is your, you only and always knows best for same. All i said, bcos like you I am gamezone cafe owner too (nvidia geforce Certified cafe) at Indore, MP, India by name of AlphaQ Gaming.

Best Paid Programme is Senet, if you can she'll off few bucks on them, they are best in market, but quality comes at price always, but you and your gamers also get tournament registration free of charge and on time, whether on discord or esfi or even esl.

Choice is always yours. Feel free to whatsapp me, if you want it, i share my whatsapp number with you.

God Bless n God Speed.
