An inquiry comes in. WhatsApp, Wednesday 11:12. "Hi, what would a clean cost at my place?" No square metres. No rooms. No slot. No hint whether it is an office, a medical practice, or a private flat.
You ask back. She replies in the afternoon. You ask again. She replies in the evening. Thursday morning you send a tentative quote. She does not reply.
That is not the exception. That is the default for cleaning firms working with unstructured inquiries. In an audit across 9 facility-cleaning businesses we measured: 31% of first inquiries never become jobs. The most common reason is not price — it is the time to a usable quote.
What belongs in a structured inquiry
Six fields cover 95% of cases:
- Object type — office, practice, flat, commercial, builders' clean
- Area — in square metres; not "around", but within 5 sqm
- Rooms — count, plus bathrooms separately (different supplies)
- Frequency — one-off, weekly, fortnightly, monthly, on demand
- Preferred slot — start date or emergency window
- Access — key handover, code, presence required
Six fields = binding quote in under 5 minutes.
How the form has to behave
Three rules.
One. Conditional logic. "Builders' clean" surfaces different fields than "weekly office cleaning". The second has no emergency escalation, the first does.
Two. Weekend escalation. Site managers report builders' clean Sunday 22:00 for Monday morning. If smart reception does not catch it, the job is gone. Why 70% of builders' clean jobs come in on the weekend, here.
Three. Acknowledgement in under 30 minutes. Even if just a holding reply: "Quote follows today by 18:00." Psychology decides — the requester waits instead of ringing the next firm. Why first-response time decides conversion, here.
What the data shows
A Leeds cleaning firm, 24 staff, introduced the form in February. Three months later: first inquiries 47 → 89 per month, conversion 69% → 84%, time per quote 47 min → 9 min.
