Why your ERP isn't enough for PO tracking
8 min read
Most people assume production buyers spend their days negotiating prices and evaluating suppliers. The reality looks nothing like that. The bulk of the job is tracking, chasing, and verifying that what was ordered actually shows up when it should.
Walk through a typical day with us. What follows is the hour-by-hour breakdown of production buyer daily tasks that rarely make it into a job description but define the role.
A production buyer manages the flow of purchased materials into a manufacturing operation. That means placing purchase orders, confirming suppliers received them, tracking delivery dates, handling changes, and escalating when something goes wrong. The job is less about sourcing and more about keeping production fed with the right parts at the right time.
The scope varies by company, but most buyers manage between 100 and 500 open PO lines at any given time. Each line is an open loop: an unresolved delivery that needs monitoring until parts hit the dock. The mental load of tracking all of them is what defines the role.
According to CourseCareers, procurement specialists spend 60-70% of their day navigating ERP systems, entering data, and resolving errors. The rest goes to supplier communication, firefighting, and trying to stay ahead of tomorrow's problems.
The day starts in email, not the ERP. A production buyer's first task is scanning overnight messages from suppliers for confirmations, ship notices, delay warnings, and questions about specs. On a typical morning, there are 30-50 new messages to sort through, most buried between newsletters and internal threads.
This is where the real production buyer daily tasks begin. You are looking for three things: who confirmed, who shipped, and who went silent. The silent ones are the problem.
Buyers who manage this well develop a system. They flag emails, copy dates into a spreadsheet, and update the ERP where they can. Buyers who skip this step lose track of things before lunch. Tools like PO-Relay's morning report exist to compress this work. Instead of reading 40 emails, you review a structured summary of what changed overnight.
By mid-morning, the focus shifts to follow-ups. Any PO that has not been acknowledged within 48 hours needs attention. A supplier that did not acknowledge your PO might not have received it, might be reviewing it, or might be ignoring it. You will not know unless you ask.
This is the most repetitive part of the day. You open the tracker, filter for unconfirmed lines, and start sending emails. Each follow-up needs context: the PO number, line items, expected dates, and a clear ask. Multiply that by 15-20 follow-ups and you have burned two hours.
Gartner's 2024 research found that 50% of purchase order lines undergo changes after issuance. That means even confirmed POs need re-checking. A supplier who confirmed last Tuesday may have sent a revised date Thursday that you missed. Auto follow-ups save the most time here by drafting messages with full context for the POs that have gone quiet.
Every production buyer knows this question. A planner, a supervisor, or someone from the floor walks over and asks about a specific part. They need it now, or they need to know when it is coming so they can adjust the schedule.
Answering should take 10 seconds. In practice, it takes 10 minutes. You check the ERP for the PO status. Then you check your spreadsheet for the latest supplier update. Then you search email for the most recent thread. Often the information does not match across all three sources.
According to Leverage.ai, buyers spend 15-20 hours per week on manual PO follow-up tasks like this: copying data from Outlook to the ERP, calling suppliers, and reconciling conflicting records. That is nearly half the work week spent on tracking, not buying. Email intelligence tools address this by reading supplier messages as they arrive and matching updates to the right PO automatically.
Afternoons are for the problems that email cannot solve. A supplier notifies you of a two-week delay on a critical component. A vendor needs updated drawings before they can ship. A quality issue on a recent receipt means you need replacement parts on an expedited timeline.
Each of these situations requires judgment, not just process. You need to assess the impact on production, decide whether to escalate, find alternatives if the delay is too long, and communicate the status to everyone affected.
The best buyers keep a short list of the five or six situations that could stop the line this week. They work that list every afternoon: making calls, pushing for answers, and updating stakeholders. The challenge is that this list changes daily, and the information feeding it is scattered across email, ERP, and personal notes.
Before wrapping up, the buyer updates whatever tracking system the team relies on. For many teams, that is a shared spreadsheet. For others, it is the ERP plus a spreadsheet. Either way, the update is manual and it takes longer than it should.
The problem with manual tracking is that it is only accurate at the moment you update it. By tomorrow morning, three suppliers will have sent new information that changes the picture. The tracker drifts out of sync within hours, which is exactly why the morning inbox triage exists. It is a cycle.
Leverage.ai reports that a typical buyer inbox contains 200+ messages with PO confirmations and shipment notices buried in them. When the tracking system depends on a person reading every email and updating every row, things slip through. A parts dashboard that updates itself from supplier emails breaks this cycle by keeping one source of truth current without manual entry.
The pattern across a production buyer's day is clear. Most of the time goes to information management, not procurement strategy. Inbox triage, follow-up emails, status lookups, tracker updates, and firefighting consume the majority of production buyer daily tasks. The actual work of evaluating suppliers, negotiating terms, and improving the supply base gets squeezed into whatever time remains.
This is not a discipline problem. It is a systems problem. The buyer becomes the system of record because no single tool holds the full picture. The ERP knows what was ordered. Email knows what the supplier said. The spreadsheet holds the buyer's interpretation of both. Keeping these aligned is a full-time job on top of the actual full-time job.
The Hackett Group's 2025 survey found procurement workloads rising 10% while budgets increase only 1%. That 9% gap has to come from somewhere. Right now it comes from buyers working harder and longer. The alternative is building systems that handle the tracking automatically, so buyers can spend their time on the decisions that actually require human judgment.
What does a production buyer do all day?
A production buyer spends most of the day tracking open purchase orders, following up with suppliers, and resolving delivery issues. The morning starts with email triage, mid-morning shifts to PO follow-ups, afternoons involve supplier calls and problem-solving, and the day ends with updating tracking systems. Strategic sourcing fills whatever time remains.
How many purchase orders does a typical production buyer manage?
Most production buyers manage between 100 and 500 open PO lines at any time. A $150 million distributor processes roughly 800 PO lines per month, and with changes that number grows closer to 1,000 entries. Volume depends on company size, product complexity, and how many suppliers the buyer covers.
What tools do production buyers use to track purchase orders?
Most buyers rely on a combination of their company's ERP system, a personal or shared spreadsheet, and their email inbox. The ERP holds official PO data. The spreadsheet tracks supplier updates the ERP cannot capture. Email contains actual supplier communication. PO-Relay connects all three into one view that stays current automatically.
Is being a production buyer stressful?
Yes. Production buyers carry the pressure of keeping manufacturing lines running. When a part is late, the buyer is the first person asked for answers. The combination of high PO volumes, constant supplier communication, and the expectation to prevent shortages before they happen creates sustained daily pressure that scales with the number of open orders.
PO-Relay gives production buyers a morning report that replaces the daily inbox dig. Every open PO, every supplier update, every at-risk delivery, summarized before your first coffee. See how it works.
