There are plenty of free tools that small businesses can use without spending money on expensive software. WhatsApp Business lets you chat with customers, send updates, and even create a small catalog of your products. Social media apps like Instagram and Facebook also have built-in features for posting stories, running basic ads, and messaging customers directly. Google My Business is another free option that helps people find your shop and see your hours, photos, and reviews right from their phones. These tools might not have all the fancy features of paid platforms, but they work great for staying connected with customers and building your brand without breaking the bank.
