Write the document, the rest is automatic
When you issue a sales invoice, stock decreases and the customer balance updates; cancel it and everything rolls back. No manual corrections.
Order → delivery note → invoice chain
Take the order, ship with a delivery note, link it to the invoice. Which order is missing what — Stokpax keeps track.
Rapid line entry
Find the item from a single search box, click, line added — the box stays open, keep adding. Finish an invoice without touching the mouse.
Invoice PDFs, generated automatically
Professional PDF invoice templates; document numbers advance automatically per year — no manual renumbering.
Inventory invoice software, not two disconnected tools
Search "inventory invoice software," "invoicing inventory software," "inventory invoicing software," "invoice and inventory software" or "invoice and inventory management software" and most results split billing from stock control — you re-enter the same line twice. Stokpax runs both as one system: the same catalog that tracks stock control also generates the invoice, so whether you call it invoicing and inventory management software, inventory management and invoicing software, invoice software with inventory or invoicing software with inventory, the workflow stays in sync automatically instead of needing a manual reconcile.
Auto parts inventory software with invoicing
Most results for that search are either a general inventory tool with billing bolted on later, or a parts point-of-sale that treats invoicing as an afterthought. Stokpax counts and bills from the same parts catalog — a counter sale looks the part up, invoices it, and posts stock in one action, so auto parts inventory software with invoicing means one workflow, not two systems synced by hand.
Auto parts billing and inventory software
A counter sale needs both at once: look up the part, bill it, and have the shelf quantity drop without a second entry. As auto parts billing and inventory software, Stokpax generates the invoice from the same catalog that tracks stock, so billing and inventory move together instead of needing a nightly reconcile between two apps. Whether the search is for auto parts store billing software or auto parts shop billing software, that's the same one-login answer — the billing screen and the parts catalog are one system, not a till app bolted onto a separate stock list.
Auto parts wholesaler inventory software
A wholesaler's invoice isn't a one-off counter sale — it's a running account with the same buyer, order after order, often against a credit line. As auto parts wholesaler inventory software, Stokpax ties every sales invoice to that customer's balance and receivables aging, so a repeat wholesale order updates stock, the invoice and what the account owes in one action, not three separate records to reconcile by hand.
Auto parts inventory and invoicing app
Running a parts counter on two separate apps means a sale has to be entered twice — once to bill it, once to drop the stock count. As an auto parts inventory and invoicing app, Stokpax is one login, one catalog: look up the part, invoice it, and the shelf quantity updates itself, so you're not reconciling a billing app against a separate inventory app at closing time.
Purchase order → purchase delivery note → purchase invoice chain
The order → delivery note → invoice chain above covers what you sell. The buying side mirrors it: raise a purchase order with a supplier, receive the stock against a purchase delivery note, then turn that into a purchase invoice — each step updates on-hand quantity and the supplier balance automatically instead of a spreadsheet tracking what's still on order. As purchase order software for small business — or purchase order management software, if that's the phrase you're searching — Stokpax isn't a general approval/procurement workflow tool built for a dedicated purchasing department; it's the restocking half of the same catalog you sell from, so what you order, receive and owe a supplier stays in one place.
Frequently asked questions
What is inventory invoice software?
It's software that combines stock tracking and invoicing in one system instead of two separate apps — the invoice is generated from the same catalog that tracks quantities, so issuing it also updates stock and the customer balance in one action. Stokpax works this way by default, with no separate stock-control add-on to configure.
Does issuing an invoice update inventory automatically?
Yes — in Stokpax an invoice and a stock movement are the same transaction. Issue a sales invoice and stock decreases and the customer balance updates in one action; cancel it and both roll back together, so the two records never drift apart.
Can I create an invoice directly from a sales order?
Yes. Take the order, ship it with a delivery note, then link the delivery note to the invoice — the order → delivery → invoice chain stays connected so you can see what's still owed on any order.
Do invoice numbers need to be renumbered every year?
No. Document numbers advance automatically and reset per year on their own, so you don't have to renumber or track sequences by hand.
Does Stokpax work as standalone delivery note software?
Delivery notes are generated from the same catalog and customer records as the rest of the order → delivery note → invoice chain, then linked to the invoice when it's created — so you don't need separate delivery note software or a manual template alongside your invoicing.
Is "delivery challan software" or "delivery order software" the same thing as delivery note software?
Yes — a delivery challan (the term used in India and other markets), a delivery order, a consignment note and a delivery receipt all describe the same document as a delivery note: proof of what shipped, linked to the order and the invoice. Stokpax generates that document from the same catalog and customer records as the rest of the order → delivery note → invoice chain, whichever regional name you use for it.
Is Stokpax sales order processing software for small business?
Yes, as one step in the same chain: take the sales order, ship it with a delivery note, then link that to the invoice — stock and the customer balance update automatically as the order moves through, so a small business doesn't need a separate order-processing tool bolted onto its invoicing.
How do I manage inventory and billing in one software?
Use a system where the invoice and the stock movement are the same transaction, not two records kept in sync by hand: issue a sales invoice and stock decreases and the customer balance updates automatically, and voiding it rolls both back together. That's how Stokpax works by default — one catalog, one login, no separate accounting-suite setup to manage inventory and billing in one piece of software.
Is Stokpax purchase order software for small business?
Yes, as the buying-side mirror of the sales chain above: raise a purchase order with a supplier, receive the stock against a purchase delivery note, then turn that into a purchase invoice — on-hand quantity and the supplier balance update automatically at each step. It's not a general-purpose procurement/approval tool, just the restocking half of the same catalog you invoice from.
