Ledgerline Payments builds private, custom integrations that connect e-commerce platforms to QuickBooks Online. Orders trigger invoices. Payments close orders. No spreadsheets, no manual reconciliation, no card data on your servers.
Built around the platforms you already use
How it works
Three asynchronous events, fully reconciled. No polling, no cron jobs, no missed orders.
Customer checks out on your storefront and selects a card-payment option. Order is created and immediately set to on-hold.
A QuickBooks invoice is generated for the order total and emailed to the customer with a secure card-payment link. Mapping persists in your database.
When the invoice is paid, an HMAC-signed webhook fires and the order is auto-completed. Idempotent — duplicate webhooks are safely ignored.
Security
Customers enter their card details directly on Intuit's hosted payment page, not on your storefront. Your environment stays out of PCI scope.

Who it's for
Online stores that want their accounting books to match their order ledger automatically — without weekly manual reconciliation.
Recurring-revenue companies that need invoice records in QuickBooks for every renewal cycle, with payment status tracked end-to-end.
Consultancies and agencies that issue invoices per engagement and want the storefront, accounting system, and payment record kept in sync.
FAQ
No. We are an integration software studio, not a payment processor or money transmitter. We build software that connects your existing payment processor (e.g., Intuit Payments) and your accounting system (QuickBooks Online) to your storefront. Funds flow directly from the customer's card to your bank account via your processor — never through us.
Our primary integration target is WooCommerce, where our QuickBooks invoicing plugin runs as a private WordPress plugin. We also build Shopify-compatible variants on request, using Shopify's webhook and Admin API. Custom storefronts can integrate via our standard webhook contract.
No. Card data is entered directly on the payment processor's hosted page. Our integration only stores order metadata (order ID, invoice ID, amount, status) and OAuth tokens — never card numbers, CVVs, or bank credentials. This keeps your environment out of PCI scope.
A standard WooCommerce ↔ QuickBooks Online integration takes 2–5 business days from kickoff to sandbox-tested handoff. Custom storefronts or non-standard accounting systems are quoted individually. Production go-live is gated by your payment processor's underwriting timeline, which is independent of our work.
Intuit retries failed webhook deliveries automatically with exponential backoff. Our handler is idempotent — duplicate deliveries are safely no-op'd by checking invoice status in the mapping table before mutating order state. Each integration also exposes a manual "resend invoice" admin action for edge cases.
