A periodic inventory system will always be a better choice for you when it comes to PERIODIC vs. PERPETUAL inventory. Retailers and other expert merchants have claimed that a periodic inventory system is better if you are just starting out, sell few products, or carry a very low budget. Perpetual is good for everyone who doesn't fall in the above-mentioned category. The moment your business grows, you will eventually turn towards the perpetual inventory. It's quite obvious as your inventory would need constant and continuous monitoring.
