Why a custom ERP?
Most growing businesses in Pakistan run on a mix of Excel sheets, WhatsApp groups and paper registers. Orders are copied by hand into challans, challans into invoices, invoices into ledgers, and the numbers stop matching somewhere in between.
Off-the-shelf packages expect you to change how you work. A custom ERP does the opposite: it uses your terms, your document formats and your approval steps, so your team keeps working the way it already does, just without the copying.
What it can cover
- Inventory and stock movements
- Purchasing and supplier ledgers
- Production planning and costing
- Orders, delivery challans and invoices
- Customer ledgers and receivables
- Payroll and expenses
- FBR digital invoicing with QR
- Owner dashboard and reports
You start with the modules that hurt most today and add the rest later. Every document your team prints, from a delivery challan to a sales tax invoice, follows your own layout.
FBR digital invoicing, built in
For businesses that must report sales to FBR, invoices can be sent through the PRAL digital invoicing API. The system stores the official FBR invoice number and prints the QR stamp on every invoice, so there is no second portal to re-type into.
Proof: an ERP I run in my own factory
I don't only build ERP for clients. I run a corrugated packaging factory in Karachi, and its orders, challans, invoices, reel stock and production run on OnePackERP, the system I built for it. Other packaging manufacturers now use it as a subscription.
That means the details that usually get missed, like costing by ply, leftover stock going back to the store, or a supplier ledger that matches their delivery challans, are things I have dealt with myself.

Questions
What is a custom ERP?
One system that holds your stock, purchases, production, sales, invoices, ledgers and payroll, built around your own documents and rules instead of a generic package you have to adapt to.
Can it send invoices to FBR?
Yes. Invoices can be sent to FBR through the PRAL digital invoicing API, which returns an official invoice number and a QR stamp for the print.
We use Excel today. Can our data move over?
Yes. Importing your existing customers, suppliers, items and opening balances is part of the launch phase.
Does it work on phones?
Yes. The system runs in the browser, so it works on laptops, desktop PCs and phones.
Where is the system hosted?
On a secure VPS with HTTPS and daily backups, and you own the code and the data.
