Write the monthly marketing report

I work in marketing at a construction firm. Help me write this month's marketing report for the partners or board.

Context: Directors want to know which sectors and services brought enquiries and tender invitations, what bids were won, and what marketing cost against that.

Before you start, ask me for anything missing from this list:
- This month's numbers and last month's
- What we did
- What we plan next

Then:
1. Lead with the three things that matter.
2. Explain each change with the evidence, and say when the cause is unknown.
3. End with decisions needed.

Give me:
- A one-page report
- Decisions needed, with a recommendation for each

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Describe building work in general terms only. Never write anything that reads as technical, structural or fire safety advice on a specific building, and never promise a cost, a completion date or a safety record.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else the director who approves marketing or our health, safety and quality lead should see:
- That no confidential client or tender details appear in the report or the AI tool
- Where the enquiry, bid and win figures came from
- Numbers too small to draw a conclusion from
