Pandemic Covid-19 berdampak pada penurunan penjualan UMKM di Indonesia secara umum tidak terkecuali pelaku UMKM Retail Banjarmasin, menurunnya penjualan akan sangat berdampak menumpuknya persediaan. Menumpukan persediaan mengakibatkan ada beberapa persediaan yang rusak, khusus untuk bahan makanan yang batas kadaluarsanya telah lewat pada akhirnya tidak bisa lagi dijual kepada konsumen. Kurangnya pemahaman bagaimana pengelolaan persediaan yang baik membuat pelaku UMKM mengelola persediaannya dengan apa adanya. Tujuan yang ingin dicapai dari program ini adalah untuk mengembangkan pengetahuan para UMKM di Banjarmasin mengenai pengelolaan persediaan barang dengan menerapkan metode First In First Out (Masuk Pertama Keluar Pertama) agar dapat meningkatkan pendapatan dengan meminimalisir adanya biaya persediaan yang expaired. Metode yang akan digunakan adalah bimbingan secara langsung oleh kami sebagai dosen Prodi D3 Akuntansi Politeknik Negeri Banjarmasin  dengan berdiskusi dan latihan/praktik di beberapa tempat pelaku UMKM bagaimana melakukan perhitungan persediaan. Melalui pengabdian ini kami mencoba melakukan transfer ilmu kepada masyarakat pelaku usaha UMKM pedagang retail Banjarmasin yang ada di sekitar Pasar Hanyar dan Kelayan B, bagaimana pengelolaan persediaan barang dagangan dengan menerapkan metode First In First Out (Masuk Pertama Keluar Pertama). Luaran yang direncanakan dalam usulan pengabdian masyarakat ini publikasi di Jurnal Implementation and Action (IMPACT) Poliban 2022.   Kata Kunci : Persediaan, metode First In First Out, UMKM Retail Banjarmasin.
