iOS and Android mobile apps for electronic invoicing

The apps allow creating and sending out estimates and invoices, tracking time and expenses incurred, and accepting or making online payments.

iOS and Android mobile apps for electronic invoicing

    Client and challenge

    Our client created an online billing and invoicing platform for businesses. The competitive market and user demand for mobile billing prompted the company to start iOS app development. However, the team lacked the resources and expertise to complete the project in time. The client reached out to EffectiveSoft for consultation and code review.

    Our team offered solutions to overcome the challenges the сlient’s in-house team faced. Thus, the client decided to delegate further iOS app development to our team. Later, Android developers joined the project to develop an Android app from scratch.

      Online billing and invoicing platform

    Solution

    The native mobile apps we developed complement the web application. The feature-rich solutions we implemented allow businesses to manage their processes automating manual work and saving time and effort. The apps enable users to:

    • Create estimates. Once they are accepted by the client, the app automatically converts them into invoices, which the client can use to make payments.
    • Accept оnline payments directly on PayPal or Stripe. Their clients, in turn, can make credit card payments right from the invoice.
    • Set up an inventory of goods sold or a list of services provided and compile invoices much faster.
    • Keep track of business finances by generating customizable reports available in such file formats as PDF, XLS (Excel), CSV, or TSV.
    • Track hours worked, miles and kilometers covered, and expenses incurred, and to turn them into invoices.

    Highlights

    Customer management

    All the saved customer information, including phone numbers, email, addresses, etc., is easy to search and add to an invoice.

    Single account for several businesses

    This function allows users to have a single user account and configure separate tabs for different businesses, each coming with their own customers and teams.

    Customizable invoices

    Users can make invoices consistent with the company’s branding and recognizable across the board by adding logos and icons, changing colors and languages right in the app.

    Recurring invoices

    Businesses regularly providing services or supplying goods to the same customers can save time by setting up recurring invoices with customizable dates, timezone, and frequency.

    User-friendly interface

    Our team designed the UI/UX for the mobile apps keeping the same look and feel as in the web platform. To follow modern trends, we added dark mode support to the apps as well.
