Every procurement team has a number they don't know: how many hours a month they spend getting new suppliers into the system. Not selecting them, not negotiating with them — just the administrative work of turning a decision into a functioning vendor record.
The number is usually between 30 and 60 hours a month for a team managing 500 or more active suppliers. That's a full-time person doing nothing but chasing forms, checking documents, and re-keying data that already exists somewhere else.
Where the hours actually go
When we work with buyers to map their onboarding process, the hours break down into five consistent categories. The proportions shift, but the categories are always the same.
First, the invitation and explanation stage. Every new vendor needs to understand what they're being asked for, why, and how to submit it. For an LLC being onboarded as a strategic supplier, that's a full compliance packet. For a student receiving an honorarium, it's a W-9 and nothing else. Someone has to know the difference, and someone has to explain it. That explanation happens by email, usually more than once.
Second, the incomplete-form cycle. This is the single biggest time sink in the entire process. A supplier submits their paperwork. It's missing the insurance certificate, or the banking details don't match the entity name, or the tax ID fails validation. The form goes back. The supplier fixes one thing and misses another. It comes back again. Each round trip costs a week and 20 minutes of someone's time — and most onboardings go through at least two.
Third, the review routing. A typical onboarding touches procurement, compliance, risk, and accounts payable. In most organisations, that routing happens through email. Someone in procurement finishes their review and forwards the file to compliance. Compliance reviews it when they get to it, then forwards to AP. If someone is out, the file sits. If it goes to the wrong person, it sits longer. The work itself takes 30 minutes. The waiting takes three weeks.
Fourth, the verification checks. Sanctions screening, tax ID validation, insurance currency, business registration — the checks that determine whether this entity is safe to pay. In a manual process, each of these is a separate lookup in a separate system. An analyst opens OFAC, runs the name, screenshots the result, pastes it into a tracker. Then opens EPLS, runs the name again. Then SAM.gov. Then the state registration database. For one supplier, that's 25 minutes. For 40 new suppliers a month, that's 16 hours — just on the checks.
Fifth, the ERP entry. The vendor record has to be created in SAP, Oracle, Workday or whatever runs the purchase orders. In most organisations, this is a manual step — someone takes the approved information and keys it into the system. Typos here create payment failures later, and payment failures are the most expensive data-quality problem in procurement.
How to calculate your own number
Pick a month. Count the number of new suppliers onboarded. Multiply by the average number of touchpoints per onboarding — if you don't know this, ask the person who does the work, because they'll know it to the hour. Then multiply by the average time per touchpoint.
For most organisations, the formula looks like this: 40 new suppliers × 6 touchpoints × 15 minutes = 60 hours. That's before you count the re-work from incomplete submissions, which typically adds 30 to 40 percent.
The number is almost always higher than anyone in leadership expects, because nobody's job is to measure it. It's distributed across four teams, and each team only sees their own piece.
What changes when you automate
The five categories don't disappear — they compress. Configurable vendor types mean each supplier gets asked only the questions relevant to their category. Pre-submission validation catches the missing fields before the form reaches your team. Parallel routing means procurement, compliance, risk and AP review simultaneously rather than sequentially. Automated screening runs the sanctions, tax ID and insurance checks in seconds rather than 25 minutes. And ERP integration creates the vendor record automatically from the approved data.
The result is typically an 80 percent reduction in hands-on time and a 60 percent reduction in cycle time. For the organisation spending 60 hours a month, that's 48 hours returned — and every onboarding completes in days rather than weeks.
The cost you're not counting
The direct labour cost is straightforward to calculate but it's not the expensive part. The expensive part is what happens when onboarding is slow.
A supplier who takes six weeks to onboard is a supplier who can't be paid for six weeks. That means either the work waits, or the work starts and the payment is improvised — a P-card purchase, a check request, a favour from AP. Each of those bypasses the controls that onboarding exists to enforce.
The other hidden cost is the suppliers you never onboard at all. A diverse supplier who gives up after the third incomplete-form email is a supplier who doesn't show up in your diversity numbers at the end of the year. A small business that can't navigate a 40-page compliance packet takes their capacity to your competitor. The onboarding process itself becomes a filter — and it's filtering for administrative tolerance rather than business value.
What to do with this
Start by knowing your number. Not an estimate — an actual count of hours and cycle days for the last quarter. That number is the business case for any change you make, and it's the baseline you measure improvement against.
