01Why It Has to Be Written Down
Why the definition has to be written and signed
The Short Version
An unwritten criterion is not a criterion — it is a preference, and it changes with whoever is in a bad mood that morning.
Ask three reps in the same company what a good lead looks like and you get three answers. One says "anyone who has a CNPJ", another says "anyone who already knows the price range", a third says "anyone the boss sent me". None of them is lying — nobody ever wrote it down, so each built a rule from the deals they personally won. Marketing then optimises against an average of three private opinions, which is the same as optimising against nothing.
Two practical consequences. First, no target can be set: "bring me 40 qualified leads" is unenforceable if qualified has no definition, so the number degrades into 40 form fills. Second, no learning accumulates: a lead discarded without a reason that maps to a written rule teaches nobody anything, and the same wrong audience keeps arriving next month.
The generic B2B concept — what the term means outside manufacturing, where it came from and how it fits a funnel — is covered at what a qualified B2B lead is. This page does not repeat it: from here on, everything is specific to a plant that sells by volume, application and lead time.
02The Five Deciding Fields
The five fields that decide, and what each one rules out
Each field exists to rule out a specific kind of inquiry you cannot serve. If a field does not rule anything out in your operation, drop it — every extra field costs conversion:
Field 01
Company and Sector
Rules out the student, the individual consumer and the researcher. Company name as a free text field, not a mandatory tax ID — asking for a CNPJ upfront scares off the engineer who is specifying from home on a Sunday. The sector tells you whether your certification covers the application, which food, pharma and oil buyers will ask about anyway.
Mandatory
Field 02
Application
The single most predictive field, and the one most often missing. "What is this going to be used for" separates the buyer who has a project from the one who is browsing a catalogue. It also lets the rep open the call already knowing whether it is a fit, which is worth more than any score. Free text beats a dropdown here — the answer in the buyer's own words carries the technical detail.
Most Predictive
Field 03
Volume or Quantity
Rules out the order that freight makes unviable. Offer ranges rather than an open number, because the buyer often does not know the exact figure yet: below your minimum, one to five times the minimum, above that, and recurring supply. Ranges get answered; open numbers get abandoned.
Freight Filter
Field 04
Deadline
Separates a live project from research for a budget that will be reviewed next year. Four options are enough: urgent, within 30 days, this quarter, no defined date. "No defined date" is not a discard — it is a lead for nurturing, and treating it as junk is how plants lose the specification phase to a competitor twelve months later.
Timing
Field 05
Role of Whoever Is Asking
In manufacturing the person who researches is rarely the person who signs. The maintenance engineer specifies, the buyer negotiates, the plant manager approves. Knowing which one you are talking to changes the whole approach: price to the buyer, technical sheet to the engineer, payback to the manager. It does not disqualify — it routes.
Routing
Asking all five without turning the form into an interrogation is a craft of its own — the order, the wording and which ones to leave for the phone call. That is covered at how to qualify technical B2B leads without scaring the buyer.
03The Rule in Three Buckets
Turning the five fields into one rule with three outcomes
A definition that only says what qualifies is half a rule, because it leaves everything else in limbo and limbo is where leads go to die. Every inquiry has to land in exactly one of three buckets, and each bucket has an owner and a deadline:
The Three Buckets
Accept — Goes Straight to a Rep
All five facts present and within range. Named owner, first contact within 2 business hours. The rep cannot refuse a lead in this bucket without writing why, and that written refusal is the audit trail of the rule.
→
Return — Missing One or Two Facts
Real company, plausible application, but volume or deadline unknown. Goes back to marketing for one enrichment attempt: an e-mail or a call asking the two missing questions, with a 48-hour limit. It becomes accept or discard after that — it never stays here.
→
Discard — Outside the Criterion
Individual consumer, competitor, reseller you do not serve, volume below the freight minimum, application your certification does not cover. Mandatory reason from a closed list of at most five options, and the weekly count by reason goes to marketing.
The written sentence:
Fill in the blanks and the rule is done — "A qualified lead is a company in [sectors] asking about [applications], for [volume above the minimum], with a deadline of [up to 90 days], from someone in [engineering, purchasing or management]. Anything missing one fact goes back for enrichment for 48 hours. Anything outside is discarded with a written reason." One sentence, on the wall, signed by whoever answers for revenue.
The rule is only real on the day a rep is turned down for refusing a lead that met it. Until then it is a document, and documents do not change behaviour.
04Validating the Rule Against History
Test the rule against orders you already closed
Before publishing the criterion, run it backwards. Take the last 90 days of closed orders — or the last 20 orders, whichever is more — and check each one against the rule as if it had arrived as a form fill. The exercise takes an afternoon and it is the only cheap way to find out whether your rule would have blocked money.
How to Read the Backtest
The number that matters is how many real orders your new rule would have thrown away. Anything above one in ten and the rule is too tight.
Three outcomes and what each one means. If the rule accepts every past order, it is well calibrated — publish it. If it blocks up to 10 percent, look at those cases individually: usually they are a small first order that grew into a recurring account, which is an argument for a "recurring supply" option in the volume field rather than for loosening the whole rule. If it blocks more than 20 percent, the rule was written from the ideal customer instead of the real one, and publishing it will cut revenue while everyone congratulates themselves on lead quality.
One more step, and it is the one that keeps the rule alive: put a date on it. Review the criterion every quarter against the same backtest, because the mix of what the plant sells changes — a new line, a new certification, a freight table that makes a smaller order viable. A criterion written eighteen months ago and never revisited is why a plant refuses inquiries it could now serve profitably.
Once the rule exists, the next question is who applies which label at which moment, and where that handoff breaks: MQL vs SQL in manufacturing. And if your leads are failing the criterion in bulk, the causes are mapped at why marketing generates unqualified leads.
05FAQ
FAQ
What counts as a qualified lead in a manufacturing company? +
An inquiry where five facts are known: which company and sector, which application, what volume, what deadline, and the role of whoever is asking. Interest alone does not qualify — those five facts do, because they are what let a rep decide whether to call and what to say. The definition must be one written sentence signed off by whoever answers for revenue.
Which fields does an industrial contact form need in order to qualify? +
Company, application in free text, volume in ranges, deadline in four options, and the role of whoever is asking — plus name and contact. Seven fields total. Application in free text is the most predictive of the set; volume in ranges gets answered while an open number gets abandoned. Anything beyond seven fields starts costing more conversion than it buys in information.
Do I need to ask about budget on the form? +
No, and in manufacturing asking it early usually backfires. The engineer who is specifying genuinely does not know the budget yet, and the buyer who does know will not disclose it to a supplier they have not spoken to. Volume plus deadline predicts purchasing capacity well enough at the form stage. Budget is a conversation for the second call.
Who should define the qualified lead criterion — marketing, sales or the owner? +
Sales drafts it, because they are the ones who know which inquiries turned into orders. Marketing reviews it for feasibility, because a criterion nobody can generate demand against is useless. Whoever answers for revenue signs it — that signature is what makes it enforceable on both sides. A criterion written by marketing alone will be ignored by sales, and vice versa.
Does BANT work for a manufacturing company? +
Partially. The authority and timing parts hold up well in manufacturing. The budget part fails at the top of the funnel because the specifier does not know it yet, and the need part is too vague to filter anything. In practice, swapping budget for volume and need for application gives you a filter that works on a plant floor. The interrogation-style version of BANT for technical buyers is discussed at /metodo/captura-e-agendamento-b2b/qualificacao-bant-industrial.
How do I write the qualified lead definition into a document? +
One sentence with the five fields filled in, followed by the three outcomes and who owns each. "A qualified lead is a company in these sectors, asking about these applications, at this volume, with this deadline, from someone in one of these roles. Missing one fact goes back for 48 hours of enrichment. Outside the criterion is discarded with a written reason." Half a page total. Anything longer will not be read twice.
Should a lead with no defined deadline be discarded? +
No. In manufacturing the specification phase happens six to eighteen months before the purchase order, and the engineer who is specifying today with no date is the one who writes your competitor into the technical sheet if you ignore them. Route it to nurturing with a quarterly technical touch, not to the discard pile. Discarding it is how plants lose deals they never knew existed.
How often should the qualified lead criterion be reviewed? +
Every quarter, using the same backtest: run the rule against the orders actually closed in that quarter and count how many it would have rejected. Review it out of cycle whenever a new product line launches, a certification is obtained, or the freight table changes — each of those moves the minimum viable order and therefore the rule.
Want the criterion written and backtested against your own orders?
We sit down with your sales team, draft the one-sentence rule, run it backwards against the last 90 days of closed orders and hand it over signed, with the discard list and the three buckets already configured in the CRM.
