Your whole business in one place

A system built to manage marketplace operations end to end

Sellyox centralizes operations, costs and business analysis so you do not have to rebuild every decision across seller dashboards, invoices and isolated spreadsheets.

Full marketplace synchronization

Update catalog, inventory, orders, fees, financial events and returns from the authorized seller account.

Line-level orders

Review gross sale, taxable base, VAT, channel fees, net received, partial or full refunds and related physical returns.

Operational inventory

Track available, reserved, inbound and unfulfillable stock together with sales metrics and recent physical returns.

Purchase recommendations

Detect urgent or recommended replenishment based on coverage, lead times, inbound stock, safety stock and historical profitability.

Purchases and landed cost

Record suppliers, invoices, batches and shipping, prep, customs and other costs to obtain the real unit cost.

Unified profitability

Measure net profit, margin and ROI including sales, VAT, channel fees, product cost, expenses, refunds and reimbursements.

Returns and refunds

Separate refunded money, physical returns, reasons, inventory disposition and channel reimbursements without mixing sources.

Business analytics

Analyze sales and profit trends, product performance, concentration, returns and other key indicators by period and marketplace.

Multi-country tax compliance

Support tax obligations in Spain and other markets with country-specific rules, automated VAT and tax calculations, filing periods and models, controlled manual inputs and alerts to review data before each filing.

Operational alerts

Centralize stockout risk, tax review issues, missing costs and other relevant situations detected by the system.

Sellyox Copilot · Artificial Intelligence

An AI assistant built into your business. Ask in natural language and let it combine sales, profitability, inventory, purchases, returns, tax and alerts using the same canonical sources as the rest of Sellyox to analyze causes, detect risks and deliver actionable conclusions.

Multi-marketplace management

Use the same architecture across marketplaces and currencies while preserving the source and context of every data point.

Aligned data

One definition for every metric

The app avoids parallel calculations: every critical data point has a canonical source and modules reuse the same logic so Orders, Analytics, Tax, Alerts and Copilot do not contradict each other.
