Bir-Fatura Integration

What Is Bir-Fatura and Why Is It Preferred?

Bir-Fatura is an e-invoice platform that has spread quickly among small and mid-sized businesses thanks to its affordable pricing and simple interface. With unlimited e-fatura and e-arşiv invoicing, mobile app support, and a straightforward user experience, it appeals to a broad user base — from new e-commerce entrepreneurs to growing businesses.

However, using Bir-Fatura on its own becomes insufficient as order volume grows. Manually entering each order into the Bir-Fatura panel and issuing the invoice is a serious time sink for a business processing 30-50 orders per day. A common complaint in Turkish e-commerce forums: “Bir-Fatura is affordable, but entering each order one by one takes forever — I wish it were automatic.”

Bir-Fatura integration solves this problem at the root. Orders from your e-commerce site or marketplaces are automatically transferred to Bir-Fatura, the correct invoice type is selected, and the invoice is issued. Our clients have reduced time spent on invoice processing by up to 80% after this integration and redirected their operations teams to value-adding work like order fulfillment and customer relations.

As Zeisoft, with our experience in e-invoice integration, we make Bir-Fatura an efficient part of your e-commerce infrastructure. Note: you own the Bir-Fatura account directly — Zeisoft is service-only, no lock-in.

How Automatic Invoice Issuance Works

The most fundamental function of Bir-Fatura integration is determining the correct invoice type and issuing the invoice automatically the moment an order arrives. Under Turkish regulations, e-fatura must be issued for corporate customers and e-arşiv invoice for individual customers. Manually performing this distinction is both a time loss and a legal risk.

Automatic Corporate vs. Individual Customer Detection

The integration system automatically performs these steps:

1. Order data is received: Order details are pulled from your e-commerce platform or marketplace
2. Tax ID check is performed: The customer’s tax ID is queried to determine corporate vs. individual status
3. Correct invoice type is selected: E-fatura is assigned to corporate customers, e-arşiv to individuals
4. Invoice is issued and sent: The invoice is created in Bir-Fatura and delivered to the customer

The entire process is completed automatically within minutes of the order entering the system. Your finance team never needs to intervene.

VAT Calculation and Product Matching

Even when different VAT rates need to be applied to different product categories, the system handles the calculation correctly. VAT rates defined per product category are automatically applied to every invoice. Thanks to Bir-Fatura’s simple structure, rate definitions are quick and easy to set up.

E-Arşiv Invoice Automation

The vast majority of e-commerce sales are made to individual customers, who require e-arşiv invoices. Bir-Fatura’s e-arşiv infrastructure, when combined with the integration, fully automates this process. For individual customer orders, the system automatically creates an e-arşiv invoice. The customer’s TC ID or tax ID is checked, the appropriate invoice type is determined, and the invoice is issued. The invoice is delivered to the customer as a PDF via email and reported to the GİB (Revenue Administration) system.

E-Commerce and Marketplace Integrations

Whichever infrastructure your e-commerce site runs on, we set up the automatic invoicing connection with Bir-Fatura. Each platform has its own order structure and data format; we manage these differences for you.

Shopify, WooCommerce, and Other Platforms

Every order from your Shopify store is automatically transferred to Bir-Fatura. Customer information, product details, and payment amount are pulled, and the invoice is created. Payments collected through virtual POS solutions like İyzico or PayTR and shipping scenarios are included in the integration.

We connect order flow to Bir-Fatura the same way for your WordPress-based WooCommerce store. Order status changes (payment received, shipped) automatically trigger the invoicing process. We also provide seamless integration with İkas and Ticimax — Türkiye-specific e-commerce infrastructures.

Automatic Invoicing for Marketplace Orders

For marketplace sellers, invoicing is one of the biggest operational burdens. Issuing invoices one by one for orders from Trendyol and Hepsiburada becomes impossible during peak sales periods. Bir-Fatura’s own marketplace connectors are limited and often require an intermediate layer.

Trendyol orders are automatically transferred to Bir-Fatura and invoiced. Hepsiburada orders flow through the same automatic process. Even when selling on both marketplaces simultaneously, each order is correctly invoiced. With our marketplace integration solutions, your invoicing burden does not grow as your sales channels expand.

Commission Invoices and Refund Management

Commission invoices issued by marketplaces to sellers are a critical but often overlooked part of the accounting process. The integration system automatically records commission deductions, matches them with sales revenue, and provides detailed reports for monthly reconciliation.

When an order is returned or partially returned, the system automatically generates a refund invoice (red invoice). For partial returns, a correction invoice is issued only for the returned items, with correct VAT calculation. This way, no manual intervention is needed in the refund process either.

Bir-Fatura’s Limitations and Our Approach

While Bir-Fatura is an affordable and useful platform, it has some technical limitations. Knowing these limitations and managing them with the right strategies is critical for uninterrupted invoicing. We design integrations with these constraints in mind.

Technical Constraints and Our Solutions

Bir-Fatura’s request capacity can become a bottleneck during peak order periods (Black Friday, 11.11, New Year). We mitigate this with the following measures:

• Queueing system: Orders are queued and processed in a controlled manner, preventing system overload
• Smart request management: Requests are sent at optimal intervals, minimizing the risk of hitting capacity limits
• Automatic retry: Invoice issuance is automatically retried in case of temporary errors or system outages
• Error notifications: For persistent issues, you receive instant notifications so intervention is not delayed

Thanks to this approach, you can invoice hundreds of daily orders without issue despite Bir-Fatura’s limitations.

Documentation Gap Issue

Bir-Fatura’s integration documentation is more limited compared to other platforms. This can cause delays and errors for businesses attempting to build the integration on their own. As Zeisoft, our experience with Bir-Fatura allows us to manage this documentation gap for you. We know all the platform’s capabilities and constraints.

Bir-Fatura, Paraşüt, and Logo Comparison

Choosing an e-invoice platform depends on your business size, order volume, and budget. The right choice directly affects integration cost and operational efficiency.

Who Is Bir-Fatura the Right Choice For?

Bir-Fatura is ideal in these cases:

• Budget-conscious businesses: Those who want to keep monthly invoicing costs to a minimum
• New e-commerce sites: Entrepreneurs whose order volume is not yet very high
• Single-channel sellers: Those selling through a single e-commerce site or marketplace
• Basic invoicing needs: Those who don’t need advanced accounting, customer account, or inventory management
• Retail sellers: Retailers newly opening online stores who need affordable invoicing

When your business grows and your needs expand, we also prepare the infrastructure for migration to more comprehensive solutions like Paraşüt or Logo. Our e-invoice integration page provides a comparative evaluation of all platforms.

Accounting Software Integration and Legal Compliance

Bir-Fatura is not a standalone accounting software — it is an e-fatura and e-arşiv invoice issuance platform. For this reason, many businesses use Bir-Fatura together with a separate accounting software. Manual data transfer between the two systems leads to duplicate records and data inconsistency.

We bridge Bir-Fatura integration with your existing accounting software. Order and invoice data is automatically synchronized between the two systems. Whatever accounting software you use, we ensure compatibility with Bir-Fatura.

2025 E-Invoice Mandate

In 2025, e-commerce companies with annual revenue exceeding 500,000 TRY are required to use e-fatura. For businesses approaching or exceeding this threshold, Bir-Fatura integration is a cost-effective legal compliance solution:

• You must issue e-fatura to all corporate customers
• You must use a system integrated with GİB
• Manual invoicing cannot keep up with legal deadlines

Bir-Fatura is already authorized as a GİB integrator for e-invoice issuance. We connect this infrastructure to your e-commerce operation to automate your legal compliance.
