New Client & Sales Proposals
4 promptsCold Proposal to a New Prospect

Proposal After a Discovery Call

Proposal for a Product or Service Bundle
3/20Draft a proposal letter offering [prospect/company] a bundle of [service or product 1] and [service or product 2] at [discount or price]. Explain the combined value in [2 to 3] sentences and give me three versions with different levels of formality.

4 promptsProposal to a Potential Business Partner
5/20Help me write a partnership proposal letter to [name] at [company] suggesting we team up on [specific idea or project]. Explain what each side brings, [my strength] and [their strength], and suggest [a meeting or call] as the next step. Give me two versions, one warmer and one more formal.
Pitches a specific partnership idea and spells out mutual benefit for both sides.

Mention what's in it for them, such as [compensation or product], and keep the tone friendly and respectful of their time. Give me two versions with different levels of formality.
A respectful pitch to a creator that leads with their benefit and keeps the ask specific.

Vendor, Contract & Renewal Proposals
4 promptsProposal to Become a Preferred Vendor
9/20Help me write a proposal letter to [company name] making the case for [my company] to become their preferred vendor for [product or service]. Highlight [advantage 1] and [advantage 2] over their current supplier. Give me two versions, one direct and one more relationship-focused.

17/20Write a short follow-up letter to [prospect name] checking in on the proposal I sent for [project or service] on [date]. Keep it brief, restate the [main benefit] in one sentence, and make it easy for them to reply. Give me two versions, one direct and one softer.

Briefly explain what's different at each level and recommend [which tier] as the best fit for their [goal]. Give me two versions of the recommendation paragraph.
