ERP software in the USA
Many US companies keep their books in QuickBooks and everything else in spreadsheets: the order log, stock counts, purchase orders, job costs. Operix builds the ERP that takes over those operations, in US dollars, with sales tax worked out by state, and leaves QuickBooks doing the accounting if that is what your accountant prefers. Our team does the work from Karachi and hands it over online.
Set up for the USA
When QuickBooks plus spreadsheets runs out
Orders, inventory across locations and purchasing move into one database, and the workbook that only one person understands is retired.
Sales tax that follows the state
States and many local jurisdictions set their own rates, so each invoice gets its tax from a tax service by ship-to address.
Connected to what you already use
Invoices, bills and payments post to QuickBooks, and orders arrive from your online store or payment processor without re-typing.
ERP software
What the ERP covers
The same ERP software we build everywhere, with the local setup above for the USA.
Purchasing and suppliers
Purchase orders, goods received notes, supplier ledgers and payment schedules, with approvals before money goes out.
Inventory and warehouses
Stock by branch and warehouse, transfers, batches and expiry dates, and reorder levels that warn you before you run out.
Sales and invoicing
Quotation to order to invoice to delivery challan, with credit limits per customer and outstanding balances on every screen.
Accounts
Journal entries post themselves from sales and purchases. Receivables, payables, bank reconciliation, and sales tax or VAT reports.
HR and payroll
Attendance, leave and salary sheets, linked to accounts so payroll lands in the books without re-typing.
Reports and dashboards
Today's sales by branch, profit by product, stock value and ageing, exported to Excel or PDF when your accountant asks.
Roles and approvals
Each person sees the screens their job needs. Discounts, write-offs and payments above a limit wait for approval.

Questions
ERP software in the USA: what people ask
Do we have to stop using QuickBooks?
No. QuickBooks can stay as the book of account, with the ERP sending it finished invoices and payments. Moving the accounts into the ERP is a later choice, not a condition.
Will the ERP handle our sales tax filing?
It records the tax charged on every invoice by state and jurisdiction and produces the report. Registration and filing sit outside the software: confirm with your tax adviser which states you must register in and what you must file.
How much does an ERP cost?
It depends on the modules, users and branches you need. We don't publish prices; message us on WhatsApp or book a demo and we'll send a written quote.
