sellerboard provides profit analytics and business management tools for Amazon sellers, and describes support for Walmart and eBay sales. Its dashboard shows sales, orders, refunds, advertising costs, estimated payouts, net profit, and business KPIs. For Amazon, it accounts for more than 100 fees and supports FIFO, constant, batch, period-based, and marketplace-specific cost-of-goods methods. The inventory planner recommends reorder timing and quantities based on sales history, seasonality, supplier lead times, and user preferences. PPC reporting breaks performance out by campaign, ad group, or keyword, and bid automation can target ACOS or profitability. Refund reports detail costs and reasons, including refunded amounts, FBA fees, commissions, and lost COGS for unsellable returns. QuickBooks can sync profit, fees, and expenses; ShipStation can provide actual FBM shipping costs for profit reports. The service has iOS and Android apps and a Chrome plugin. Standard costs $19 per month billed monthly, or $179 billed annually ($15/mo). A one-month free trial is offered without a credit card.
