Connect AI to QuickBooks Desktop.

Ask Claude or ChatGPT about your real QuickBooks Desktop books, and let it do the work: who owes you, last month's sales, a draft invoice. For Pro, Premier and Enterprise.

Use it on the QuickBooks computer out of the box, across your office network with one setting, and from anywhere, including claude.ai and ChatGPT, with LedgerCrossing Remote (or your own tunnel).

“Which customers are more than 60 days overdue, and how much do they owe?”
“What were sales by month this year?”
“Which items are below their reorder point?”
“Draft an invoice for Acme for 3 hours of consulting at $95. Show it to me before saving.”

Answers come from your QuickBooks Desktop company file, not a copy.

LedgerCrossing includes an MCP server — connect Claude Code, Cursor, or any MCP-capable assistant. It rides the same HTTP API as everything else, so it works with anything you've built. Six tools: list the 240 qbXML operations, get one operation's field rules, validate a request, run it, explain a QuickBooks status code, and check status.

It can create and edit records, not just read, so connect it to company files you mean it to touch. Runaway requests for your whole file are blocked by default, and QuickBooks' own audit trail records every change.

Included in the product. Not a tier, not a preview, not a limited-time unlock.

Use it free on the QuickBooks machine or your office network; reach it from anywhere with your own tunnel (free guide) or LedgerCrossing Remote ($39/mo — you're paying for the hosted relay, not the AI).

The Problem

The QuickBooks Web Connector is Broken.

If you use QuickBooks Desktop and need to sync data with any other system, you know the pain. The Web Connector crashes constantly, throws cryptic errors, and requires someone to manually restart it every single day. It is 2026 and you are still babysitting a SOAP-based polling agent from 2002.

Crashes constantly — admins report unrecoverable errors almost every single day

Cryptic error codes (QBWC1085, QBWC1039) with zero useful information

Silently fails when QuickBooks shows any modal dialog or update prompt

Requires QuickBooks to be running and logged in at all times

No real-time sync — it polls on a schedule, and short intervals make it unstable

The Solution

LedgerCrossing: Install Once. It Just Works.

LedgerCrossing is a lightweight Windows application that replaces the Web Connector entirely. It exposes a simple REST API that accepts qbXML requests, so your systems can push data into QuickBooks and pull data out: on the QuickBooks machine out of the box, across your office network with one setting, and from the cloud through your own tunnel or LedgerCrossing Remote. No SOAP servers. No polling. No crashes.

Runs quietly in your system tray — starts automatically, never needs babysitting

Direct qbXML pass-through — send and receive data instantly

Designed for long-running stability — no more daily crashes or manual restarts

On your machine or office network, your data stays in-house — it never transits anyone else's servers

Reachable across your office network with one setting — or from anywhere, via your own tunnel or Remote

Works with all QuickBooks Desktop versions including Enterprise

Compatibility: if it can make a web request, it can talk to QuickBooks Desktop through LedgerCrossing — custom code, integration platforms, internal tools, anything. One honest caveat: off-the-shelf apps that sync through the Web Connector today are controlled by their vendor, so LedgerCrossing is not a drop-in replacement underneath them.

Use Cases

What Runs Through LedgerCrossing?

Anything that needs to read from or write to QuickBooks Desktop — without the Web Connector in the middle.

Unattended server syncs

Integrations that run on a schedule without anyone logging in to restart the Web Connector. LedgerCrossing runs quietly in the system tray and handles itself.

"I have to restart QBWC every single day."

Field service & job costing

Job costs, estimates, and invoices flowing between field software and QuickBooks Enterprise without data gaps.

"Our field data never matches QuickBooks."

E-commerce order sync

Orders, customers, and payouts moving from Shopify, WooCommerce, or Amazon into QuickBooks Desktop without a connector breaking every week.

"The QB Desktop connector is a nightmare."

Inventory & manufacturing

Inventory counts, assembly builds, and purchase orders kept in sync between an MRP system and QuickBooks Enterprise.

"We cannot move to QBO — no assembly builds."

Custom integrations

New integrations built without the SOAP nightmare — send qbXML directly over HTTP instead of standing up a Web Connector service from scratch.

"Wait, I need a SOAP server just to create an invoice?"

CRM & billing sync

The end of the double data entry tax. When the integration actually works, every transaction flows without manual re-keying.

"The numbers in our CRM never match QB."
