What Kartial Does

Everything between a sale
and your actual profit.

We calculate what competitors don't: true net profit inclusive of VAT offset, withholding tax, commissions, shipping, and cost of goods.

📊
Real Profit Engine
Net profit calculated after marketplace commissions, VAT, withholding tax, shipping costs, and product cost of goods — nothing hidden.
🔗
Multi-Platform Sync
Connect Trendyol, Hepsiburada, Etsy, Amazon and more. All your orders, inventory, and profits in one unified dashboard.
🏗️
Bill of Materials Tracking
Multi-level BOM support for complex products and semi-finished goods. Understand your true cost per SKU, even for bundled or handmade items.
📄
Invoice Parsing (e-Fatura)
Upload Turkish e-Fatura and e-Arşiv PDF invoices. Kartial extracts line items automatically — no manual entry, no raw file storage.
📦
Smart Inventory Management
Shared stock pools with channel-specific pricing overrides. One product, multiple marketplaces, zero confusion.
📈
Historical Snapshots
Kartial takes time-stamped snapshots of your data. Compare profit across any period, track trends, and never lose historical context.
The Formula Others Skip
Most tools just subtract commission. Kartial goes further.

API & Platform Compliance

Built on official APIs.
Designed for trust.

Kartial integrates exclusively through each marketplace's official developer API program. We follow all platform terms of service, rate limits, and data usage policies.

🔐
OAuth 2.0 Authentication
Sellers connect their accounts via each platform's official OAuth flow. We never ask for or store login credentials.
📋
Minimal Data Scope
We request only the permissions needed: orders, products, and inventory. We do not access financial accounts, payments, or messaging.
⚡
Rate Limit Compliance
Our sync engine respects each platform's API rate limits. We use polling and queuing patterns to stay within allowed thresholds.
🏢
Registered Developer Account
Kartial is operated as a registered business entity with an active developer account on each integrated marketplace.
🔄
No Scraping. Ever.
All data is fetched exclusively through official API endpoints. We do not scrape, simulate browsers, or reverse-engineer platform interfaces.
📜
Terms of Service Adherence
We actively review platform policies and update our integration to stay compliant with any changes to developer program terms.

Your data is yours. Always.
Kartial operates under Turkish data protection law (KVKK) and follows industry-standard security practices. We do not sell or share seller data with third parties.
