What Is GenInvoice? An Automated E-Invoicing Solution

GenInvoice is an automated e-invoicing solution for Amazon and Etsy sellers, enabling order synchronization, batch invoice generation, complete reconciliation, and regulatory compliance.

What Is GenInvoice? An Automated E-Invoicing Solution
For e-commerce sellers, as daily order volumes grow from just a few transactions to hundreds, the workload involved in issuing e-invoices increases accordingly. Accounting teams need to retrieve marketplace data, enter the information into e-invoicing software, and verify buyer and transaction details before invoices can be generated and issued. If the entire process remains manual, processing time increases significantly as the business scales, while additional effort is required to review and reconcile the data.
The challenge, therefore, is not simply generating e-invoices, but handling a growing volume of transactions without a corresponding increase in manual work. GenInvoice was developed to address this challenge through an automated e-invoicing process that connects sales data directly with invoice generation and issuance, helping e-commerce sellers process increasing order volumes more efficiently.
 

1. What is GenInvoice?

GenInvoice is an automated e-invoicing solution for e-commerce sellers that currently supports sales data from Amazon and Etsy. Instead of downloading marketplace data, processing it through spreadsheets, and then entering it again into e-invoicing software, GenInvoice connects order data directly to the invoice generation and issuance process.
Once synchronized, sales data is standardized and processed before invoices are generated. Each invoice is created based on the corresponding transaction data and remains linked to the original order, allowing businesses to review and reconcile the information when needed. This approach reduces repetitive data entry and helps prevent order data, e-invoices, and accounting records from being managed separately across multiple systems.
GenInvoice operates on Genbook, a platform that supports financial data processing and management for cross-border e-commerce businesses. By connecting the e-invoicing process to the same source of sales data, businesses can maintain greater consistency across transactions, invoices, and accounting data instead of reconciling multiple data sources after invoices have already been issued.
For sellers handling large transaction volumes, GenInvoice is designed to shift invoice processing from handling individual transactions manually to a more centralized workflow, where data is synchronized, processed, and used consistently from the original order through to the invoice.
 

2. 4 Limitations of Manual Invoicing That GenInvoice Can Address

2.1 High Transaction Volumes

Each completed order requires a corresponding invoice. When a business operates across multiple stores and marketplaces, the number of invoices to be generated can reach thousands each month. Processing each transaction individually requires time and manpower that increase with sales volume, even when the value of each individual order is relatively small.

2.2 Multiple Manual Data Entry Steps

In a manual process, sales data is typically downloaded from the marketplace, processed in spreadsheets, and then entered into e-invoicing software. Moving data through multiple steps increases the risk of discrepancies in transaction values, exchange rates, or buyer information, particularly when businesses are handling large order volumes.

2.3 Time-Consuming Review and Reconciliation

Order data is managed on marketplaces such as Amazon, Etsy, or Shopee, while e-invoices are stored in a separate system, making reconciliation between the two data sources more time-consuming. Businesses need to identify transactions that have not yet been invoiced, invoices containing discrepancies, and returned or canceled orders that require further processing.

2.4 Increasing Compliance Requirements

As transaction volumes grow, businesses need not only to issue e-invoices at the appropriate time but also to ensure that invoice data remains consistent with sales data and accounting records. When these steps continue to rely heavily on manual processing, maintaining consistency across different data sources becomes increasingly time-consuming and difficult to manage.
 

3. How GenInvoice Handles the E-Invoicing Process

GenInvoice connects sales data with the e-invoice generation and issuance process within a single system. From the moment an order is synchronized until the corresponding invoice is issued, data moves through a consistent workflow, reducing the need to download files, re-enter information, and perform manual reconciliation.

3.1 Centralized Sales Data Synchronization and Management

Order data from Amazon or Etsy is synchronized with GenInvoice and centrally managed by legal entity, store, and time period. Instead of accessing individual seller accounts to download and consolidate reports, businesses can manage the data that needs to be processed in one place before moving on to invoice generation.

3.2 Data Processing and Automated Invoice Generation

Using the synchronized data, GenInvoice processes transaction information such as order status, sales value, and buyer details to automatically generate invoices. Invoices are initially created as drafts, allowing businesses to review and approve the information before issuance, reducing manual data entry while retaining the necessary level of control.

3.3 Batch Invoice Issuance

Once approved, multiple invoices can be issued in batches instead of being processed individually. The data is then transferred to the e-invoicing service provider to complete the issuance process and transmit the required data in accordance with the applicable procedures.

3.4 Invoice Status Tracking and Reconciliation

After issuance, businesses can centrally monitor the number of draft invoices, issued invoices, failed issuances, and the total value of invoices issued. The status of each invoice is retained alongside the corresponding transaction data, making it easier to review and reconcile invoices against orders when discrepancies arise.
 

4. How Does GenInvoice Optimize the E-Invoicing Process?

The value of GenInvoice goes beyond automated invoice issuance. It lies in the way sales data remains connected throughout invoice generation, issuance, and reconciliation, significantly reducing manual processing as transaction volumes increase.

4.1 Reducing Manual Data Entry

Instead of downloading reports from Amazon or Etsy, consolidating them in spreadsheets, and then entering the information again into e-invoicing software, order data is synchronized and used directly to generate invoices. This reduces repetitive data entry and helps minimize discrepancies between marketplace data and invoice data.

4.2 Processing Large Invoice Volumes Within a Single Workflow

GenInvoice automatically generates invoices from transaction data and allows multiple invoices to be issued in batches after they have been reviewed and approved. As order volumes increase, businesses do not need to process each invoice individually as they would in a manual workflow, reducing the time spent on repetitive tasks.

4.3 Reconciling Orders and Invoices Within the Same System

Transaction data and e-invoices are managed centrally, allowing businesses to review the number of transactions processed, invoices issued, and the status of each invoice. Maintaining a link between each invoice and its original order also makes it easier to investigate discrepancies or trace transactions when needed.

4.4 Maintaining an Efficient Process as Transaction Volumes Grow

With a manual approach, data entry and reconciliation workloads typically increase alongside order volumes. GenInvoice automates repetitive steps within the e-invoicing process, allowing businesses to handle larger transaction volumes without a corresponding increase in manual workload.
 

5. GenInvoice Pricing and Packages

GenInvoice offers flexible packages based on each business’s e-invoice issuance needs. The initial license package includes software access, digital signature services, and invoice incentives for new customers. Businesses can purchase additional invoice packages based on their actual transaction volume, ensuring a suitable solution for their current operations and future growth.

6. Automating the E-Invoicing Process with GenInvoice

As transaction volumes on Amazon or Etsy increase, manual e-invoicing requires more time for data entry, review, and reconciliation.
With GenInvoice, the e-invoicing process is connected directly to sales data rather than operating as a separate step after each transaction. This helps e-commerce sellers on marketplaces such as Amazon or Etsy reduce their reliance on manual data entry while maintaining consistent invoice data as transaction volumes and business operations grow.
