Order management software for small teams — sales order to invoice
Order management software usually means a heavyweight ERP and a six-month rollout. StockZip stays inventory-first: run the whole chain — sales order → pick list → delivery order → invoice, plus purchase orders and receiving — so stock levels, documents, and history always agree without retyping anything between systems.

Sales orders are the source of the chain — pick lists, delivery orders, and invoices are generated from them, so nothing is retyped between documents.
How it works
Record what the customer wants against your item list. The sales order captures the demand and becomes the single source for every later document in the chain.
Generate a pick list from the sales order, fulfil it by scanning items at the shelf, then convert it to a delivery order. Picked stock is deducted from inventory automatically — no separate adjustment step to forget.
Generate the invoice straight from the sales order — no retyping line items. If a delivery fails, mark it returned and the stock comes straight back into inventory, recorded in the audit trail.
Everything you need in one place
You get the inventory operations layer — the orders and the documents that move stock — at small-business pricing. Your accounting stays in QuickBooks or Xero; a QuickBooks Online sync for invoices and purchase orders is built and coming soon.
One chain: sales order → pick list → delivery order → invoice. Each document is generated from the previous one, so line items flow through instead of being retyped into a new screen.
Build a purchase order from your item list, email it as a PDF, and receive against it line by line — full or partial. Received quantities enter stock automatically at the right location.
There is no separate inventory adjustment to remember. Receiving adds stock, picking removes it, a returned delivery brings it back — quantities and paperwork always agree.
Every receive, pick, delivery, and adjustment logs who did it, when, and against which document. When a count looks wrong, the answer is in the history — not in anyone’s memory.
Documents track ordered versus fulfilled quantities, so partial deliveries, partial receiving, and backorders stay visible instead of getting lost in a spreadsheet.
