QuickBooks for accounting. Celerp for everything else.
Keep QuickBooks for your books, or replace it entirely. Celerp adds multi-location inventory, manufacturing, barcode scanning, and purchase orders - with or without QuickBooks.
Free, with open-source modules. Connect sync from $29/mo.
What QuickBooks can't do
QuickBooks is accounting software. It was not built to manage inventory or operations.
No multi-location inventory
QuickBooks tracks stock as a single number per item. If you have multiple locations, you are guessing. Celerp tracks per-location with real-time visibility.
No manufacturing or BOM
QuickBooks has no bill of materials, no assembly tracking, no production orders. Celerp handles full manufacturing workflows.
Limited barcode support
QuickBooks has no native barcode scanning. Celerp includes it free - scan to receive stock, pick orders, and do cycle counts.
Desktop being sunset
QuickBooks Desktop is being discontinued. Users are forced to QuickBooks Online, which has even fewer inventory features. Celerp is a free alternative.
Connect Celerp to QuickBooks in 3 steps
Download and install Celerp
pip install celerp or download the desktop app for Mac, Windows, or Linux. Takes under 2 minutes.
Connect to QuickBooks
In Celerp, go to Settings - Connectors - QuickBooks. Click Connect QuickBooks and authorize on Intuit's website. Customers, items, and invoices sync.
Your inventory stays in sync
Every stock movement in Celerp updates QuickBooks. Bills and invoices sync automatically. Your books stay balanced.
How to migrate from QuickBooks Online to Celerp
Celerp reads the lists and reports QuickBooks Online exports.
Export your books from QuickBooks Online
Export the Account List, the Customer and Vendor Contact Lists, the Product/Service List, the Journal report, Sales by Customer Detail, Purchases by Vendor Detail, Invoices and Received Payments, Bills and Applied Payments, a Trial Balance as of the last day of each financial year and of the ledger, each run from the first day of its financial year, and A/R Aging Detail and A/P Aging Detail as of the last day of the ledger. The transaction reports can be exported a year at a time. Celerp lists each file and where to export it.
Upload them to Celerp
Install Celerp, choose Move your books from another system, pick QuickBooks Online as your current system and add the files, one at a time or as one zip. Each file is checked when you add it.
See what comes across
Before anything is imported, Celerp lists every kind of record in your file or files and shows what comes across, what comes across in part, and what it cannot bring over yet.
Choose full history or a cutover date
Full history recreates every transaction. Cutover starts from a date you choose: balances on that date become opening balances, and open invoices, bills and stock are recreated.
Check the results
Celerp compares its totals with the totals in your file or files and shows any difference. Download the reconciliation pack for your records or your accountant.
Your QuickBooks Online company stays as it is. Celerp only reads the exported files, so you can keep working in QuickBooks until you are happy with the result.
What moves from QuickBooks Online
Celerp shows this for your own file before you import anything.
Comes across
Chart of accounts, customers and vendors, products and services, invoices, bills, credit memos and vendor credits with the payments applied to them, and every entry in the Journal report. Voided invoices and bills come across as void. Invoice and bill lines keep their class and location as tracking options; journal lines do not.
Checked against your file
The trial balance on each date you exported it for, each customer's and vendor's balance, and each invoice's and bill's total, status and amount due. Each is compared with the figures in your QuickBooks files.
Listed, not moved
Estimates, purchase orders and other records that post nothing are not in the files Celerp asks for, so recreate the ones you still need.
Not supported yet
Stock quantities on hand are not imported: count your stock in Celerp after the import. Celerp does not report by class or location.
Staying in step with QuickBooks
Two-way sync keeps your back office and accounting always in agreement.
QuickBooks contacts sync to Celerp CRM. Track order history, lifetime value, and communication.
Celerp invoices push to QuickBooks automatically. Purchase bills sync on receive. COGS is recorded per transaction.
Products sync between systems. Celerp manages stock levels; QuickBooks sees the financial impact.
One-time import of your QuickBooks chart of accounts into Celerp. Full accounting stays in sync.
