Online invoicing and payment app service\u00a0WePay just released a new app for iOS devices that allows small businesses to send invoices and charge credit cards from mobile devices. While businesses have plenty of other options for accepting credit card payments via phones or tablets, the new payment app gives small businesses one more choice to manage mobile payments. And those who already use WePay online will now have a way to manage their accounts on the go. Because of its focus on professional invoicing, WePay is aimed more at small businesses and professionals than are other mobile payment solutions like Square and Paypal, which offer features for\u00a0both businesses and individual users. In addition, the WePay payment app doesn\u2019t need any extra hardware like a card reader. Instead, it does require users to enter credit card numbers manually. Credit card processing and invoicing both come with a fee of 2.9% and $0.30 per transaction. The payment app accepts all major credit cards, and there are no contracts or monthly fees associated with the service or the app. The first photo above shows a default app page, where users can see their account balance and choose to send money to their bank accounts, charge a credit card, or send an invoice. They can also choose to view pending invoices and recently received payments. The second photo shows an itemized invoice, where users can break down each good or service they provided and the individual prices for each. They can also set a due date and even a late fee. The third photo shows a list of unpaid invoices a user has sent to different parties, allowing them to see how much money they have coming in and the due dates of each invoice. The WePay service also offers support for e-commerce, donations, event registration, and ticketing. The company, a team of 48 based in Palo Alto, California, was originally founded in 2008.
