Ibu rumah tangga di desa Kalirejo Kecamatan Negeri Katon, Kabupaten Pesawaran, Provinsi Lampung memproduksi tapis dengan skala home industry untuk menambah pemasukan ekonomi keluarga. Namun selama ini produksi tapis dengan skala tersebut memiliki kelemahan terutama dalam hal inovasi produk. Produk tapis yang dihasilkan hanya seputar selendang dan kain sarung saja. Hal ini berdampak pada jumlah penjualan karena tapis hanya digunakan dalam kegiatan formal saja seperti acara adat ataupun pernikahan. Hasil dari turunan produk tapis pun masih di dominasi kalangan dewasa; belum menjangkau kalangan remaja. Hal ini dikarenakan desain serta bentuk turunan tapis yang ada saat ini dinilai belum sesuai dengan perkembangan masyarakat sekarang. Maka dari itu perlu adanya inovasi untuk memperbarui produk yang sudah ada agar dapat lebih menarik perhatian konsumen dan memiliki perbedaan dengan produsen lainnya. Sehingga nantinya akan berdampak pada kenaikan jumlah pemakaian yang secara tidak langsung juga akan berpengaruh pada kenaikan jumlah penjualan.

Terutama di pasar e-commerce jika orang menemukan produk serupa dengan harga lebih rendah dan kualitas lebih tinggi, mereka dapat dengan mudah pindah dan membeli dari pesaing yang lebih gesit. Masalah belanja online lainnya adalah layanan pengiriman yang buruk yang mengakibatkan kedatangan produk terlalu lama atau bahkan rusak. Layanan pengiriman sangat penting dalam e-commerce, karena merupakan tahap terakhir dari proses pemenuhan pesanan dan dari sudut pandang konsumen, yang paling kritis. Pengiriman tepat waktu dan andal harus menjadi prioritas nomor satu dan sangat penting untuk keberhasilan setiap toko online.
