Square is an excellent billing solution, offering a budget-friendly way to streamline your invoices and ensure you get paid on time. Rather than focus on fancy features, it hones in on automating your invoicing and payment reminders — and does them well. And if you want to add more tools to your business, Square has other PoS and e-commerce features. Square won’t do your bookkeeping for you, but fortunately, you can integrate it with other products to cover those areas. So if you need a way to manage your billing more efficiently, consider Square.
