LedgerBox

What is LedgerBox?

LedgerBox is a browser-based tool that converts financial documents into structured data; it is operated by Lumen Holdings LLC in Wisconsin, United States. It is designed for bookkeepers, accounting firms, financial teams, lending institutions, and developers who need to process large amounts of transaction data.

After the user uploads a PDF, a scanned document, or photos from a smartphone, the system identifies the structure of the pages and the financial fields involved, and organizes the information into editable, verifiable, and exportable tabular data. Its focus is not on general text recognition, but rather on extracting financial tables, performing arithmetic checks, and integrating with accounting software.

Main functions

• Extract financial data from digital PDFs, scans, and photos.
• Identify bank and credit card statements, invoices, receipts, and paystubs.
• Handle purchase orders, broker reports, checks, tax forms, and merchant settlement statements.
• Mark uncertain rows as pending review, rather than deleting them silently.
• Perform an arithmetic check based on the opening balance, closing balance, and total transactions.
• Export to Excel, CSV, QuickBooks CSV, QBO, and JSON.
• Send approved transactions via a QuickBooks Online connection.
• Use APIs, TypeScript SDKs, Webhooks, and MCP to integrate automation processes.
• Collect pending documents through the customer portal and email forwarding.

Supported document types

LedgerBox uses the same upload and verification process for various types of financial documents, but each document yields different fields and verification results. When a document page contains no structured data, it is sent to the OCR process; digital PDFs, on the other hand, have their text and layout read directly.

Input format and file restrictions

Extraction and verification of financial data

The system will analyze the table structure, align the columns, and extract the information that is actually printed on the page, row by row. Bank statements are verified by checking the opening balance, transaction amounts, and closing balance, while invoices and purchase orders have their detailed totals checked to ensure they equal the total amount specified in the document.

• Split the date, description, debit, credit, and balance into separate fields.
• Maintain a single row per transaction to facilitate filtering and summarization.
• Provide a label and the reason for rows that cannot be verified.
• Users are allowed to review and modify the recognition results before exporting them.
• The original content will not be replaced with guesses based on categories that are not supported by documentation.
• No unified and accurate accuracy rate applicable to all banks and formats has been published.

Comparison of export formats

Excel and combined export

The Excel output is not a simple text file with a changed extension; it is a workbook that can be opened directly in Excel, Numbers, and Google Sheets. Dates remain as dates, and amounts remain as numbers, which facilitates sorting, summing, and creating pivot tables.

• By default, it includes columns for date, description, debit, credit, and balance.
• The table headers are set to be frozen, so that the fields can still be viewed as the long statement scrolls.
• The debit and credit amounts are kept separately to avoid confusion regarding positive and negative signs.
• Add a document name column when merging multiple statements.
• Multiple files can be combined into one workbook.

QuickBooks workflow

All paid plans allow the download of QuickBooks CSV and QBO files; plans at the Pro level and above also enable the sending of approved documents to QuickBooks Online. File export and direct online connection are two distinct functions, and it is important to keep this in mind when choosing a plan.

1. Upload bank statements or other supported financial documents.
2. Wait for the extraction to complete and check the verification status.
3. Review each marked transaction and balance discrepancy individually.
4. Approve the document and select a QuickBooks CSV or QBO file.
5. With a Pro or higher plan, it is possible to connect to QuickBooks Online and synchronize the accounts.
6. In the accounting software, verify again the debit and credit directions, duplicate transactions, and the ending balances.

Batch processing and automation

Plans Pro and above support up to 20 files per batch, as well as Webhooks, automated workflows, and email forwarding. The Business plan is designed for higher monthly page volumes and team collaboration, while the Enterprise plan offers additional options such as custom integrations, white labeling, and on-premises deployment.

• Create batch tasks and view the processing progress in one place.
• Download a single result at a time or combine the results.
• Receive customer documents by forwarding emails.
• Use Webhooks to monitor document completion or status changes.
• External clients can submit documents through the customer portal.
• Apply for custom integration for specific business systems.

Free trial

The new workspace can be tried out for 14 days without the need to provide a credit card; it initially includes 10 pages. By inviting colleagues, sharing content publicly, submitting reviews, or selecting a package, up to 200 pages can be unlocked during the trial period. The actual number of tasks that can be used is determined by the instructions displayed in the account.

Prices and packages

The price information was verified on August 23, 2026; the actual amounts, taxes, exchange rates, and discounts may vary, and the final figures will be those displayed on the settlement page.

LedgerBox is subscribed based on the number of pages to be processed; each page of a document counts as one unit, and no fees are charged based on the number of transactions or exports. The quota is reset at the end of each settlement cycle, and processing stops once the limit is reached; no additional charges for exceeding the quota are issued automatically.

Page range and upgrade rules

Each standard package also offers different page count options: Starter covers 60 to 300 pages, Pro covers 640 to 1500 pages, and Business covers 2000 to 5000 pages. The price for the higher tiers varies depending on the number of pages selected; therefore, it is necessary to check the final amount based on the actual monthly page count at the time of purchase.

• A 12-page bank statement will consume 12 pages of space.
• A photo of a receipt is usually counted as 1 page.
• Re-exporting the same result will not incur additional charges per row.
• When the quota is insufficient, processing is paused; it resumes after an upgrade.
• Upgrades during a subscription period usually only incur a charge for the remaining duration.
• Annual payment is approximately 30% cheaper than monthly payment; the actual taxes and currency will be as indicated on the settlement page.

How to choose among different packages

API, SDK, and MCP

LedgerBox offers a document processing interface that utilizes API keys for authentication; it allows files to be uploaded, the status of tasks to be checked, and structured JSON results to be obtained. Each response includes information on the verification status of the document as well as a flag indicating whether it needs further review, which helps programs decide whether to allow the data to be included in the ledger.

Open-source status

The LedgerBox platform, the recognition models, and the server-side components are not open-source products; therefore, it is not possible to classify the entire tool as open-source merely on the basis of an open SDK. The TypeScript SDK and the client components related to MCP are licensed under the Apache-2.0 license, with the openness applying mainly to the code used to call these interfaces.

• The open-source status of the products in the tool catalog should be marked as no.
• The fact that the SDK is open source does not mean that the recognition service can be deployed for free.
• API calls still require a LedgerBox account and a valid credit limit.
• Do not link to the repository of the encryption hardware project Ledger with the same name.
• Enterprise local deployment is a commercial solution; it is not the same as open-source self-hosting.

Privacy and data security

Documents and extraction results are encrypted both during transmission and when stored statically; the minimum required connection standard is TLS 1.2, and tenant isolation is implemented by the organization. The processing environment is located in the United States, and the uploaded data is not used for training, fine-tuning, or evaluating models.

• The document is stored in private storage locations in the United States, where independent model deployment takes place.
• The processing workflow does not include any step for manual review.
• The platform will not sell customer documents or use them for advertising.
• Internal services access data with the minimum required permissions.
• Maintain audit records for management actions and production changes.
• The database is backed up daily, and the backups are retained in accordance with internal policies.
• There are currently no available SOC 2 Type I or Type II reports.
• Currently, there is no self-service data processing protocol available, and SAML or SCIM are not supported.

Saving and deletion mechanisms

Documents in regular work areas are not automatically deleted after 30 or 90 days; they remain stored until the user initiates the deletion process and completes the necessary steps for erasure. At present, to completely remove stored files and data rows, a deletion request must be submitted – the removal action displayed in the account interface does not constitute actual erasure at the underlying level.

The customer portal allows setting a deadline for files; the uploaded files are removed once extraction is complete, but the structured documents resulting from that extraction are not automatically deleted as a result of this setting. Before processing sensitive files such as bank statements or identification documents, it is necessary to determine the company’s own retention period, any cross-border requirements, and the procedures for terminating such processing.

Standard usage process

1. Create a workspace and verify the email address.
2. Select bank statements, invoices, receipts, or other document types.
3. Upload a clear PDF or a supported image file.
4. Wait for the system to extract the table and complete the arithmetic verification.
5. Check all the marked rows, account periods, and ending balances.
6. Based on the subsequent system selection, choose Excel, CSV, QBO, or JSON.
7. When automation is required, create API keys, Webhooks, or MCP connections.
8. After the recording is completed, delete the document in accordance with internal policies and confirm that it has been erased.

Pre-purchase checklist

1. Test the completeness of fields using a real but properly anonymized document.
2. It is necessary to determine whether the review markers can cover the most common layout errors in business documents.
3. Count the actual number of pages in documents on a monthly basis, rather than just counting the number of files.
4. Confirm whether file export is required or a direct connection to QuickBooks Online.
5. Assess whether batch uploading, email forwarding, and Webhooks are needed.
6. Check the monthly/annual pricing, page count options, taxes, and the cost difference for upgrades.
7. Confirm that the handling procedures and document retention rules in the United States are in compliance with internal policies.
8. Before making a purchase, companies should ask for audit reports, data processing agreements, and proof of deletion.
9. Before integrating the access, test the API limits, asynchronous status, and error retry mechanisms.
10. Maintain manual approval and duplicate transaction checks before official recording.

Frequently Asked Questions

Is LedgerBox free?

LedgerBox does not offer a permanently free, unlimited-version plan, but it provides a 14-day trial period without the need for a credit card; this trial includes 10 pages initially. After completing the required actions to unlock additional features, the number of pages available in the trial can be increased up to 200.

Can it convert scanned bank statements into Excel?

Yes, PDF files and photos from mobile phones can be processed via OCR, while digital PDF files can be read directly. Before exporting, it is still necessary to check the date, amount, direction of transactions, and balance.

Can LedgerBox import CSV data and then convert it to QBO?

No, it can only read PDF files and supported image documents; it does not accept CSV, QBO, OFX, QFX, or QIF files as input. Existing data files need to be converted using other tools in different formats.

Is QuickBooks supported?

All paid plans allow for the download of QuickBooks CSV and QBO files, while plans at the Pro level and above enable sending these files to QuickBooks Online. The trial period permits testing of the online integration, but downloading of QuickBooks files is not possible during this time.

Are APIs and SDKs provided?

It offers REST APIs that use API keys for authentication, along with TypeScript SDKs, Webhooks, and MCP integration options. The Starter version includes the APIs and SDKs, while Webhooks are available starting from the Pro version.

Is LedgerBox an open-source tool?

No, the platform, recognition models, and server-side components are closed-source commercial products. What is available publicly is the TypeScript SDK under the Apache-2.0 license, along with the related calling components.

Will the document be deleted automatically?

Documents in regular work areas are not automatically deleted after a set number of days; to completely remove files and retrieve data, it is necessary to submit a request according to the existing deletion procedures. The customer portal allows setting an expiration date for uploaded files, but it does not automatically delete the results obtained from those files.

Summary

LedgerBox is suitable for teams that need to organize statements, invoices, receipts, and other financial documents into data ready for accounting purposes. Its advantages lie in its arithmetic verification features, markers indicating items awaiting review, a variety of export formats, as well as multiple ways to access it, from the browser to APIs and MCPs.

Before official adoption, it is essential to verify the accuracy of format recognition, the number of pages per month, the QuickBooks workflow, and the deletion mechanisms. In cases involving regulatory requirements or purchases by large enterprises, it is also necessary to ensure that the location of data processing in the United States, SOC 2 reports, single sign-on capabilities, and data processing agreements meet the required standards.
