La Cajita is a point-of-sale and inventory system for small retailers in Argentina: kiosks, grocery stores and clothing shops. It runs in the browser, with nothing to install. It includes barcode scanning, split payments, customer tabs, cash shifts with blind counts, variants by size and color with their own stock, photo and price, exchanges with an exchange ticket, and an online store on the same stock as the counter, paid through the shop's own Mercado Pago with no commission per sale. The Premium plan adds ARCA e-invoicing with no invoice limit, unlimited staff with per-person permissions and up to 2 shops per account. Prices are published in Argentine pesos, from ARS 12,000 per month, with a 20-day free trial.
