The real cost of silent POs
Updated August 2026
Buyers live in a two-front squeeze.
Planning/production is chasing them from the inside (“can we start the job Monday?”) while they chase suppliers on the outside for the answer. In between sits the open order report, the spreadsheet, and an inbox where the truth actually lives.
How POs go into silences
The PO that was never acknowledged. It went out as a PDF; nothing came back. Things could easily slip through and resurface when something is really wrong. One buyer’s summary of the job: a lot of emails, chasing quotes, updating POs, fixing vendor screwups.
The acknowledgment that means nothing. The supplier confirmed three weeks ago and has gone quiet since. A confirmation is like a snapshot. If the supplier never sends the update, the confirmed date just stands in the record until the parts fail to arrive.
The confirmation, then the change. Confirmed for the 12th; an email on the 3rd says the 23rd. If a buyer catches it, planning reshuffles early and cheaply. If it sits unread in one inbox — vacation, volume, or the wrong buyer — the ERP keeps promising the 12th to everyone downstream, and the miss is discovered at kitting.
Three ways the same PO line goes quiet.
How the silent POs cost the company
Buyer hours. Handling one PO line across its life — reading the reply, digging up the PO, comparing line by line, re-keying the tracker and the ERP, chasing the silent — runs about 20–30 minutes. At a $45 loaded hour, that is at least $15 a line in labor before anything goes wrong. A site running 4,000 lines a month is spending roughly $648K a year of buyer time keeping records current.
An SVP of supply chain at an electronics manufacturer measures 30–50% of his buyers’ week going to exactly this; a director of strategic supply chain at an aerospace components manufacturer told us chasing purchase orders is 80 to 90 percent of his buyer-planners’ time, and supplier development is “pretty much out of the question.”
Bought-back time. A slip found late is bought back at a premium: expedited freight instead of ocean or ground (0.6–1.5% of direct-material spend, of which a quarter is avoidable with earlier discovery), and supplier rush fees on compressed lead times (0.25–0.7% of spend). On $150M of spend, those two slices alone run at least $1M a year.
Buffer stock. Inventory held against what you cannot see. When the record can’t be trusted, safety stock quietly becomes the insurance policy, and working capital pays the premium: carrying inventory costs 20–30% of its value a year, so two extra weeks of cover on $150M of spend — about $5.8M of stock — is another $1.2–1.7M a year.
The revenue at stake. All of the above ends at the customer: a slip found late at kitting or receiving is either bought back at a premium, or the schedule is resequenced and the promise date slips.
Across manufacturers, 44.5% of organizations report losing 3–4% of annual revenue to supply-chain disruption. A VP of supply chain at a $600M manufacturer told us he missed his number by about 15% in a single year — roughly $50 million of opportunity — to production delays from parts nobody tracked in time. “Just stupid stuff,” he said.
The labor cost of PO management.
What good PO management looks like
What good PO management looks like is visibility into the state of supply, with a loop closed around it.
Every open line shows days since sent and acknowledgment status. Silence past a threshold produces a drafted chase for a buyer to approve, not a mental note. A reply that moves a date becomes a proposed change with the email attached as evidence; one click updates the ERP and notifies the owner.
That visibility is what the business objectives rest on. Situational awareness: planning works from the real state of supply instead of the date the ERP is still promising. Risk management: a slip surfaces the day the supplier’s email arrives, while resequencing is still cheap, not at kitting. On-time delivery and working capital follow from those two — fewer expedites, less buffer stock, and a promise date the customer can trust.
That is what Cronwell builds from the inbox your buyers already have — the record baselines from email history in the first week, and suppliers never change how they work.
The VP of Operations at a consumer-audio manufacturer, after connecting: “We connected the mailboxes and the record was already there. There was nothing for our suppliers to sign up for.” The CIO of an electronics manufacturer: “My buyers didn’t have to learn anything new. It works where they already work.”
Run the arithmetic on your own site: open-PO lines per month, times ~20 minutes, times your loaded rate. The calculator does the labor floor in two minutes. If the number annoys you, bring it to a 30-minute call.
