Logo E-Invoice Integration

What Is Logo E-Invoice and Why Is It Preferred?

Logo is Türkiye’s most established and widely used enterprise accounting software. Particularly favored by mid-to-large businesses, Logo Tiger and Logo Go bring accounting, inventory management, customer account tracking, and e-fatura/e-arşiv invoicing under a single roof. From manufacturing companies with hundreds of employees to retail chains, a broad user base relies on the Logo infrastructure.

However, using Logo on its own creates a serious bottleneck once e-commerce order volume grows. Manually entering each order into Logo and issuing the invoice turns into an hours-long operation for a business processing 50-100 daily orders. While your accounting team spends the day on data entry, strategic financial work is delayed. On top of that, manual entry frequently causes customer-account matching errors, wrong VAT rates, and invoice-type mix-ups.

Logo e-invoice integration solves this at the root. Orders from your e-commerce site or marketplaces are automatically transferred to Logo, the correct invoice type is determined, the customer account is matched, and the invoice is issued. Our clients have reduced invoice processing time by up to 85% after this integration and redirected their accounting teams to reporting and analysis.

Beyond that, Logo’s periodic version updates can break existing integrations. Testing is mandatory after every update, and invoicing can be disrupted in the meantime. Logo’s on-premise architecture also prevents direct connection with cloud platforms like Shopify or İkas, requiring a bridging layer.

As Zeisoft, with our experience in e-invoice integration, we solve all these challenges for you and make Logo an indispensable part of your e-commerce infrastructure. Note: you own the Logo license directly — Zeisoft is service-only.

E-Invoice Management with Logo Tiger and Logo Go

Logo has two main product families, and each has a different e-invoice integration approach. Choosing the right product with the right scope optimizes both cost and timeline.

Logo Tiger E-Invoice Module

Logo Tiger is a comprehensive business management software offering enterprise-level accounting, production planning, human resources, and supply chain management. The e-invoice module is one of Tiger’s strengths:

• GİB integration: Direct integration with the Revenue Administration
• Bulk invoice issuance: Hundreds of invoices processed in a single batch
• Multi-company support: Centralized invoicing for multiple companies or branches
• Advanced accounting integration: Accounting entries are automatically generated the moment an invoice is issued

Tiger’s biggest limitation on the e-commerce side is the lack of direct marketplace or e-commerce platform connectors. An intermediate layer is needed to transfer order data into Tiger — and that’s exactly the layer we build.

Logo Go E-Invoice

Logo Go is a lighter accounting solution targeted at small and medium-sized businesses. Compared to Tiger, it offers basic accounting, e-invoicing, and customer account tracking at a lower license cost:

• Basic e-invoice issuance: Single or bulk invoice generation
• E-arşiv invoice support: Automatic e-arşiv for individual customers
• Customer account management: Tracking customer and supplier accounts
• Basic reporting: Sales, receivables, and payables reports

For Go users, integration is faster than Tiger because the module structure is simpler. However, some Go limitations (such as the lack of advanced inventory management or multi-warehouse support) can affect integration scope.

Which Logo Product Is Right for You?

If you already use Logo, we build the integration on top of your existing structure. If you’re at the Logo selection stage, we also help you determine the right product based on your e-commerce volume and needs.

E-Commerce Platform Integration with Logo

Logo’s on-premise (on-site installation) architecture cannot communicate directly with cloud-based e-commerce platforms. This technical difference is the main reason many businesses leave the question “How do I connect Logo to my e-commerce site?” unanswered. We bridge these two worlds with a secure connectivity layer.

Shopify Integration with Logo

Every order from your Shopify store is automatically transferred to Logo. Customer information, product details, and payment amount are pulled, matched with the relevant Logo customer account, and an invoice is created. Shopify’s various payment methods, discount coupons, and shipping processes are included in the integration. When your Logo inventory cards are matched with Shopify products, inventory automatically decrements after a sale.

WooCommerce Integration with Logo

For your WordPress-based WooCommerce store, we connect the order flow to Logo. Order status changes (payment received, shipped, etc.) automatically trigger the invoicing process. Thanks to WooCommerce’s flexible structure, custom order fields and tax rules can also be reflected in the Logo integration.

İkas and Other Platforms

We also provide Logo integration with İkas and Ticimax — Türkiye-specific e-commerce infrastructures. Order flow on these platforms is matched one-to-one with Logo’s invoicing and inventory processes.

Automatic Logo Invoicing for Marketplace Orders

For marketplace sellers, invoicing is one of the biggest operational burdens. Manually entering each Trendyol and Hepsiburada order into Logo becomes unsustainable during peak sales periods. With our marketplace integration solutions, marketplace orders flow through the same automated process and are invoiced in Logo. Commission deductions are recorded separately, and monthly reconciliation reports are generated automatically. Whichever channel you sell through, all invoicing runs centrally through Logo.

Inventory and Customer Account Synchronization

One of Logo’s strongest features is its comprehensive inventory management and customer account tracking infrastructure. However, if this data is not synchronized with your e-commerce platform, you end up maintaining duplicate records on two separate systems. This means both wasted time and data inconsistency.

Inventory Card Synchronization

Your Logo inventory cards (product name, code, price, VAT rate, unit) are matched with products on your e-commerce platform. With this matching:

• When a sale occurs on the e-commerce site or marketplace, Logo inventory automatically decrements
• When you define a new product in Logo, it automatically appears on the e-commerce platform
• You can update prices in Logo and propagate them to all channels
• Automatic alerts are generated for products falling below minimum stock levels

If you use Logo Tiger, the multi-warehouse structure can also be incorporated. Which warehouse fulfills an order can be automatically determined based on the order region.

Customer Account Automation

For e-commerce orders, a customer account must be created in Logo for each customer and the balance tracked. In a manual process, this means opening a new customer card or finding an existing one for each order.

With integration, this process is fully automated:

1. When a new customer arrives, a customer account is automatically created in Logo
2. When an existing customer places an order, the relevant customer account is found and matched
3. When an invoice is issued, the customer account balance is automatically updated
4. When payment is received, the payment information is reflected in the customer account

We optimize your Logo customer account structure to fit your e-commerce needs.

Reporting and Financial Analysis

Logo integration is not limited to invoice issuance. By combining your e-commerce data with Logo’s powerful reporting infrastructure, you can comprehensively analyze your business’s financial position:

• Channel-based sales reports: Revenue per e-commerce platform or marketplace
• Product-based profitability analysis: Sales performance and margins per product group
• Customer account aging report: Receivables tracking and maturity analysis per customer
• VAT reports: Periodic VAT calculations and declaration support
• Returns and cancellations: Return rates, reasons, and financial impact
• Commission reports: Detailed breakdown of marketplace commission deductions

These reports are delivered through Logo’s own reporting module. With virtual POS integration, you can also include payment data in these reports. Custom reports and unified dashboards can be developed as needed.

On-Premise vs. Cloud: Running Logo with Modern Infrastructure

One of Logo’s defining characteristics is its on-premise (on-site installation) architecture. Logo software runs on your own server or local computer. This structure offers data security and control advantages but makes direct communication with cloud-based e-commerce platforms like Shopify or İkas difficult.

How the Bridging Layer Works

To connect Logo’s on-premise structure with your cloud e-commerce platform, we develop a secure intermediate layer. This layer:

• Pulls order data from your e-commerce platform
• Transforms data into the format expected by Logo
• Writes to the Logo database via secure connection
• Reflects inventory and price changes in Logo back to the e-commerce platform

Data transfer occurs over encrypted channels. Server access requirements and security configuration are determined during the discovery phase.

Logo License Costs and Module Selection

Logo’s licensing model is module-based. E-invoice, inventory management, multi-warehouse, and other features are each licensed as separate modules with additional cost. Modules required for e-commerce integration:

• E-invoice module: Mandatory (for e-fatura and e-arşiv issuance)
• Inventory management module: Required if inventory synchronization is desired
• Customer account module: Included in the base package
• Multi-warehouse module: Required if you have multiple warehouses (Tiger only)

To avoid purchasing unnecessary modules, it’s important to define your integration scope clearly. We analyze which modules you actually need during the discovery phase, helping you avoid unnecessary license costs.

Logo or Cloud Solution?

Logo’s on-premise structure and license costs may be heavy for small e-commerce businesses. For a business taking 10-20 daily orders that doesn’t yet have a Logo infrastructure, cloud-based solutions like Paraşüt or Bir-Fatura offer a more economical and faster start.

However, for businesses already using Logo, with high order volume and advanced accounting needs, Logo integration is the right choice. Logo’s comprehensive accounting infrastructure, multi-company support, and detailed reporting capabilities provide depth that cloud solutions cannot match. As part of our e-commerce solutions, we build the right invoicing infrastructure for any scale.
