Volta Corporation is a company that simplifies the cumbersome and complex process of issuing electronic tax invoices. It enhances work efficiency by enabling not only individual business owners but also corporate members to check electronic tax invoices within the platform. The company is expanding its service area to facilitate the issuance and verification of cash receipts as well.
Reducing Electronic Tax Invoice Issuance Time from 5 Minutes to 5 Seconds…‘Volta Corporation’

Lee Moon-hyuk, CEO of Volta Corporation, stated, “We often hear that the method of issuing electronic tax invoices, which was thought to never change, has finally changed through Volta. For instance, it used to take about 5 minutes to issue an electronic tax invoice through multiple categories and complex authentication procedures on Hometax. By utilizing our service ‘Volta,’ electronic tax invoices can be issued with minimal information input and a single click after the initial authentication. We are providing the service after acquiring the National Tax Service's standard certification for electronic tax invoices,” adding, “Employees in the finance teams of large companies are constantly bombarded with inquiries beyond their main duties. For example, if 20 sales team members simultaneously ask one finance team member about the issuance of electronic tax invoices, the finance team member has to check all and then notify them back. This type of simple task delays the core work of the finance team, often leading to overtime. Using Volta can significantly enhance the work efficiency of the finance team.”

He continued, “Issuing electronic tax invoices is not the end; post-processing tasks are also necessary. The transaction must be confirmed as completed by verifying actual deposits. On the Volta platform, not only can electronic tax invoices be issued, but also the integration of deposit and withdrawal details allows for a clear view of outstanding and unpaid statuses. It also aids in the easy preparation of complex and difficult expense reports,” and added, “A scheduled issuance function is also provided to support the issuance of tax invoices related to regularly recurring transactions every month.”

Lee Moon-hyuk explained that the inconveniences experienced while working in large corporations, public institutions, and startups became the motivation for founding Volta.
He said, “The task of issuing electronic tax invoices linked to sales always arises suddenly. Due to communication errors, the amount or date may be incorrect, necessitating reissuance,” and added, “This can lead to conflicts among team members. The finance team claims they received incorrect information and should not be held responsible, while the sales team insists they communicated accurately over the phone and demands quick corrections, prioritizing it over other tasks. Meanwhile, the customer becomes dissatisfied. By using Volta, members can clearly verify contract, estimate, and tax invoice data anytime, anywhere, preventing such disputes and enabling quick responses.”

Listening to Practitioners’ Feedback: The Background of ‘Service Enhancement’

Volta Corporation is a company with the mission of ‘everything starts from the customer's difficulties.’ Not only the CEO but also developers and designers meet with client companies to converse and incorporate feedback into the service. Thanks to this philosophy, there have been cases of service improvement.

Lee Moon-hyuk stated, “In the early stages of the business, while trying to simplify the task of issuing electronic tax invoices as much as possible, we guided not to enter industry and business type information, which is not mandatory. As a result, the time taken for issuance was significantly reduced, but after meeting practitioners directly, we received feedback that although it is not mandatory, industry and business type information is customarily included,” and added, “We immediately incorporated the feedback into the service, and now the information is automatically retrieved, improving convenience. If we hadn’t met practitioners face-to-face to hear their opinions, quick responses would have been difficult. No matter how busy, developers and designers accompany meetings to listen to opinions.”

He continued, “Being selected for the Jungle ASAP program hosted by Seoul National University of Science and Technology was also a great help in improving the service,” and added, “Through this program, we connected with Amazon Web Services (AWS) and were able to confirm market strategies, pricing strategies, and technical strategies necessary for SaaS companies, as well as references from other SaaS companies. We also learned about the existence of the AWS Marketplace through this collaboration. Even without going abroad, it is useful for renowned overseas companies to access Volta’s services through the AWS Marketplace.”

Finally, he shared Volta Corporation’s future plans.

Lee Moon-hyuk stated, “This year, we achieved a tenfold increase in client companies compared to last year. While expanding client companies is important, service retention rate is also crucial. Currently, Volta shows a retention rate of about 98%. Particularly, the active adoption by large corporations makes us feel the increased market recognition,” and added, “Our ultimate goal is to create an AI-first service that handles all miscellaneous tasks of the finance team and assists in strategic decision-making. To this end, we are planning to update additional features in November to assist with cash receipt issuance and history verification. We will continue to be a company that listens closely to the voices of client companies and immediately reflects them in the service to resolve difficulties.”
