Order management is not software. It is the chain of steps between a customer buying and you being paid — and most small businesses lose orders in the handoffs, not in any individual step.
Order management is everything that happens between a customer placing an order and the transaction being closed: capture, confirmation, stock allocation, picking, dispatch, invoicing, payment, and whatever returns follow. Vendors sell it as a system; for a business under a few hundred orders a month it is a written sequence with owners, and the system is optional.
The reason to write it down is that orders are almost never lost inside a step. They are lost in the gaps — the order that arrived by email while the person who checks that inbox was away, the one that was picked but never invoiced, the one where the customer paid and nobody marked it.
The handoffs are where to put your attention, not the steps. Each transition — capture to allocation, pick to invoice, dispatch to collection — is a place where an order can stop moving with nobody noticing, because everybody assumes it is now somebody else's. The cheapest control is a single list of open orders with a status, reviewed daily, where anything that has not moved in two days is visible.
The threshold is not order volume alone. It is when orders arrive through more than one channel, when stock is sold in more than one place, or when more than a couple of people touch the same order. Any of those makes a shared list insufficient, because two people will act on stale information. Below that, a spreadsheet with a status column and a daily look at it genuinely works, and the money is better spent elsewhere.
Ettex Invoices holds the order through to invoicing and payment, with the paperwork chain covered in delivery note and the stock side in inventory management. Orders arriving through a shop sit in Ettex Sites, where the payment step is discussed in checkout page, and the delivery expectations you set in shipping policy.
The boundary: this is not an order management system. There is no channel integration, no multi-warehouse allocation, no automated picking workflow and no carrier connection. If you are selling across marketplaces with shared stock, buy a dedicated product — that is exactly the situation it exists for.
The whole sequence from an order being placed to the transaction being closed: capture, confirmation, allocation, picking, dispatch, invoicing, collection and returns.
When orders arrive through more than one channel, stock is sold in more than one place, or several people touch the same order. Below that, a shared list with statuses works.
The share of orders delivered complete, on time, undamaged and correctly invoiced. It is deliberately harsh because it measures what the customer actually experiences.
In the handoffs between steps rather than inside them — capture to allocation, picking to invoicing, dispatch to collection. A daily review of open orders by age catches most of it.
A delivery note is not paperwork for its own sake. It is the only evidence of what left you and what the customer received — and the argument it prevents is the one about a missing item three weeks later.
Credit control is the set of decisions made before an invoice exists — who gets terms, how much, and what happens when they slip. Chasing is what you do when those decisions were never made.
AP automation is sold as one product, but it is four separate jobs with very different payback. Capture and matching are where the software earns its price; approval and payment are mostly a question of whether anyone wrote the rules down.
