Blue Lime Ledger Deck

When to use

• Your quarterly results need a board-ready deck and the spreadsheet alone won't carry the story
• A budget review meeting is coming and you need every variance explained on one slide each, not buried in footnotes
• You're pitching a pricing proposal and the client needs to see exactly what they pay and what they get
• An audit or compliance summary has to be readable by non-accountants without losing a single figure
• An investor update needs revenue, burn, and runway on three slides that a tired reader can absorb in sixty seconds

Workflow

1. Collect the numbers (input: spreadsheets, statements, or pasted figures → output: verified number sheet)
   Gather every figure the deck will show: revenue, costs, variances, runway, pricing tiers — with the period each covers and the source it came from. One number sheet, one source of truth. Round consistently (whole dollars or thousands — pick one and stick to it), and flag any figure you're unsure about instead of guessing. No number enters a slide until it appears on this sheet.
2. Shape the story (input: number sheet → output: slide outline)
   Decide the one message per slide before touching any design. The standard arc: where we are (headline numbers) → what changed (variances, with reasons) → what it means (implications in plain language) → what happens next (asks and decisions). Cut any slide that doesn't move that arc forward. A finance deck earns trust by being short, not by being exhaustive.
3. Build the ledger tables (input: slide outline + number sheet → output: table slides)
   Every table follows the ledger rules: right-aligned numbers, one decimal style throughout, subtotals ruled above and totals ruled below, and a variance column that shows both the amount and the direction (▲/▼ with color, never color alone). Each table gets a one-line takeaway above it — the reader should grasp the point before reading a single cell.
4. Apply the Blue Lime system (input: table slides → output: styled deck)
   Deep navy background panels for headers and key-number callouts, lime used only for the single most important figure or trend on each slide, silver-grey for supporting text and gridlines. One typeface family, two sizes for body text at most, and generous white space around every table. If a slide has two lime highlights, one of them is wrong — lime means "look here first."

Template preview

Blue Lime Ledger Deck — Template

One deck = one number sheet + one slide outline. Fill both in before styling anything.

Deck: {title} — {period, e.g. Q3 2026}

Audience: {board / client / investors / team} | Rounding rule: {whole $ / $ thousands} | Sources: {list}

Number sheet (single source of truth)

Unverified figures (do not put on slides until confirmed): {list or "none"}

Slide outline (one message per slide)

Ledger table format (copy per table slide)

Takeaway: {one line the reader gets before reading the table}

Style checklist

• [ ] Navy headers, lime on the single most important figure per slide only
