7 Sales Materials That Help Your Team Close More Deals

Written by Nick Biela | August, 18, 2025

Most sales reps don’t fail because they lack hustle. They fail because they’re under-equipped.

You can have the best product, service, or pitch in the world but if your team doesn’t have the right sales materials to support that conversation, you’ll lose deals to competitors who simply came better prepared.

At The Diamond Group, we help businesses build sales enablement systems that actually move the needle from first outreach to signed contracts. Here’s what we recommend every sales team have on hand to boost credibility, improve conversions, and close more consistently.

1. A Company Overview One-Pager

This is the “who we are” piece, not the “here’s our entire story” piece.

Too often, companies overload prospects with dense brochures or underwhelming About Us pages. Instead, create a clean, modern one-pager that highlights:

  • Who you help
  • What you do (in plain English)
  • Key differentiators
  • Social proof (logos, stats, or testimonials)
  • A clear call to action

Documents should support first meetings, email follow-ups, and outbound outreach. And spoiler alert: Your website is one of the most important parts of your brand and the way customers can really learn about who you are. Zendesk reports that 81 % of buyers research products online before talking to sales.

2. Case Studies That Prove Results

Every buyer wants to know: “Can you actually do what you say?” That’s where case studies come in.

Strong case studies:

  • Follow a problem > solution > outcome format
  • Highlight quantifiable wins (think: 3x ROI, 50% faster close time)
  • Include direct quotes from clients
  • Show off your process—not just your results

Extu notes that 80% of B2B buyers consult case studies and that 88% of marketers rate them as the most effective content

Tip: Build a few short-form versions that can be dropped into outbound emails or proposals. You don’t need a 4-page PDF every time.

3. A Value-Driven Sales Deck

This isn’t your investor pitch. It’s not a slideshow of logos. It’s a narrative tool.

The best sales decks:

  • Lead with the buyer’s challenge, not your features
  • Show a clear solution path (bonus points for visuals or models)
  • Keep text minimal and talking points clear
  • End with next steps, not a vague “thank you” slide

Sales decks should work across live presentations and asynchronous shares. If it doesn’t work in both formats, it’s time for an upgrade. Read more on our blog about “The Power of Storytelling in Sales”. 

4. Objection Handlers and FAQ Sheets

Most sales reps already know the 5–7 objections they’ll face. “Too expensive.” “Not the right time.” “I need to check with my team.”

So why not arm them with messaging that works?

Marketing can help create:

  • PDF or internal-only FAQ sheets with tested responses
  • Slides or snippets to use during follow-up
  • Supportive content like blog links or videos that defuse objections indirectly

Not only does this help your reps close, it creates a more consistent buyer experience.

5. Pricing Sheets That Build Trust (Not Confusion)

No one likes vague pricing. But dropping a flat number with no context can be equally harmful.

Your pricing materials should:

  • Be easy to understand
  • Include tiered options if available
  • Reinforce value through outcomes or ROI
  • Address common billing or contract questions

Bonus: create an internal version with guidelines for reps so they’re never unsure how to present pricing confidently.

6. Post-Demo Recap Email Template

After a call or demo, buyers often forget half of what they heard. The follow-up email is your second chance to make it stick.

A good recap includes:

  • A clear summary of what was discussed
  • A restatement of the buyer’s goals
  • Links to relevant resources (case studies, blog content, explainer videos)
  • A single next step (calendar link, proposal review, or discovery call)

Marketing can create branded, ready-to-edit templates to make this fast and repeatable.

7. A Proposal That Feels Like a Solution, Not a Spreadsheet

Your proposal is often the last thing someone sees before deciding to buy. It should reinforce trust, not raise questions.

We recommend proposals that:

  • Include a personalized intro
  • Reiterate outcomes, not just line items
  • Feature your process or methodology
  • Showcase success metrics, testimonials, or guarantees
  • Are easy to sign and return digitally

Why These Materials Matter More Than Ever

Today’s buyers don’t want a hard sell, they want confidence. When your sales team has high-quality, strategically designed materials, they:

  • Feel more prepared
  • Deliver a more consistent story
  • Shorten the decision cycle
  • Handle objections with ease
  • Look more credible and professional

And that leads to one thing: more closed deals.

Want Materials That Actually Work?

The Diamond Group helps B2B companies design and deliver sales content that closes. From decks to proposals to entire email sequences, we create marketing-driven assets that support your team at every stage of the pipeline.

We’ll help you:

  • Audit your current materials
  • Identify where deals are getting stuck
  • Build what’s missing with your brand and voice in mind
  • Connect sales and marketing into one system

Because great sales teams don’t just talk. They show—and close—with the right tools.
