From a customer nod to cash in the bank, a deal at least crosses quote, lock, outbound, receipt, invoice, and apply. Each hop that changes file or group adds another “I thought.” The system’s job is that the next step sees the qty and price already confirmed — finance does not guess again at month-end.
Fights stick on the arrows, not on department names
All four sentences can be true because no document pinned “agreed → shipped → invoiced.” The arrows require: a qty change edits the order and re-locks; free goods are a line; invoicing reads shipped qty, not sales memory. Stock matching the books is the base of this chain. See How a system makes inventory match the books.
Price and terms follow the order, not the chat
The same customer can have different discounts on different orders, but each order’s price must trace an approval. “Same as last time” in the group is no price in a cash fight.

See Sales and finance looking at the same customers and contracts.
Apply cash to goods, or reconciliation is not over
A round bank deposit that cannot split across shipments becomes a prepay; sales thinks it is closed. The system lets one receipt apply to many orders, or one order take many receipts, with a reason: shortage, warranty, allowance. What a customer exports is this chain — audit wants the same. See What the system does when you reconcile, audit, or a customer asks for a document. These changes can go in a weekly report. See The efficiency a business system can make visible.
Partial ship and returns are the two arrows that snap first
One order on three trucks, invoiced as the full qty, and the customer refuses the gap invoice. A return that does not release reserved stock inflates inventory. Allow line-level partial outbound, invoice what shipped, and release or return stock — each step with a reason. Finance integration can wait; those three steps must be continuous in the operations system. After growth, partial ship is daily. See Why growth requires an operations system of your own. Allowances and swaps on a work order should hang back on the same sales order, so cash-apply does not open another blurry book. See After work orders close the loop, what changes in after-sales and quality.
When DaXi Technology builds intake-ship-reconcile, invoicing sits after shipped qty — not after “sales thinks we can invoice.” Phase one can make outbound create A/R; finance-software integration can wait for phase two.
