The background to this research was that one of the MSMEs (Micro, Small, and Medium Enterprises) participating in the Lestari Guide, "Dapoer Niswah," was facing challenges such as inadequate promotion. For example, the business's web page was unusable and difficult to find, and when users wanted to order, there was no information available. Furthermore, other issues arose when business owners were still stuck using manual methods like Excel for financial calculations, including profit and loss, disorganized record keeping, and slow reporting. This research aimed to address the challenges faced by the Dapoer Niswah MSME. The MSME needed a new promotional page and an information system that could address the limitations of the manual system. The Dapoer Niswah Jamu MSME needed to develop a new interface for its website, which was essentially outdated and no longer usable. The author conducted a trial by entering Mrs. Niswah Lestari's sales data into an AIS program to facilitate this. Based on the existing SOPs, the author conducted the research at the location for approximately three months. As a result, the Dapoer Niswah MSME can now operate with a new perspective. Implementing a website or Accounting Information System (AIS) at Jamu Dapoer Niswah has resulted in significant operational and financial changes.
