Proposal Mistakes That Lose Deals (and the Fix for Each)

These five mistakes appear in most losing proposals. Each takes minutes to fix — part of the winning proposal playbook.

1. Scope without quantities

"Full electrical works" invites disputes; "42 outlets, 18 lighting points" prevents them. Measurable scope is a trust signal. The same principle applies to money — see 7 proposal pricing mistakes.

2. No exclusions section

Every undefined boundary becomes unpaid work. List what is not included (FF&E, signage, third-party fees) as plainly as what is.

3. No expiry date

A proposal without an expiry is a quote that lives forever — and gets decided never. Date yours at 14 days and schedule the close (read how to follow up).

4. No single next step

"Let me know what you think" ends proposals; "Reply to accept and we schedule kickoff within 5 working days" moves them. One action, one timeframe.

5. Generic credibility claims

"High-quality service" and "tailored solutions" without a backing detail read as filler. Replace every adjective with a number: crew size, years, sites completed, response time.

Apearl's proposal structure enforces all five by default: quantified scope blocks, exclusions, expiry with reminders, a next-step close, and numbers pulled from your company knowledge.
