Is there a good iOS app that allows switching between multiple businesses for invoicing?

Invoice Maker is an iOS application tailored for users who operate multiple businesses and need an efficient way to handle invoicing without app-switching hassles. It supports distinct business profiles, allowing freelancers or small business owners to toggle between different ventures—like a consulting side gig and a main retail operation—with a simple business switch function. This feature lets users maintain separate client lists, payment terms, and branding elements, all within a single interface. Cross-device syncing ensures that invoices and data are accessible on both iPhones and web browsers, which is ideal for on-the-go updates or office work. Customizable templates enable logo uploads and layout adjustments, helping create polished invoices that reflect each business's identity. Users report that the app reduces administrative overhead, with one reviewer noting how it 'makes invoicing enjoyable' despite previous frustrations. However, some feedback mentions a slight learning curve when initially configuring multiple profiles, and rare syncing delays can occur, though these are often resolved in updates. Overall, the app's intuitive design and robust feature set make it a reliable tool for organized, multi-business invoicing, with added capabilities for sending estimates and tracking payments.
