Indigo Ledger Landing

When to use

• You sell bookkeeping, accounting, invoicing, or expense software and your landing page needs to feel trustworthy to people who read numbers for a living
• Your current landing page leans on hype ("revolutionary!", "10x!") and your finance-savvy buyers don't believe a word of it
• You need a landing page whose whole argument is transparency: show the price, show the math, show the workings
• You are launching a finance tool for small businesses and want a visual identity that says "careful with your money" instead of "startup casino"
• Your pricing page is where deals stall because the numbers feel hidden or slippery

Workflow

1. State the honest argument (input: product + price → output: one-page argument)
   Write the landing page's argument as a ledger would: what the product costs, what it replaces, and what the buyer saves, in plain numbers with the arithmetic shown. No superlatives, no "up to" claims, no asterisks. If you can't state the value in one honest paragraph with real figures, the page isn't ready for design — fix the offer first, because a ledger-style page makes vague claims look worse, not better.
2. Set the ledger system (input: argument → output: visual system)
   Define the visual language: deep indigo ink on warm paper white, hairline rules that separate every row like a ledger, tabular numerals (figures that line up in columns), and a single serif for numbers and headlines with a plain sans for body text. Every section is a ledger entry: a ruled header, aligned columns, a subtotal line. The design rule is simple — if it wouldn't look at home in a well-kept account book, it doesn't go on the page.
3. Draft the sections in ledger order (input: visual system + argument → output: page draft)
   Lay out the sections the way a ledger reads, top to bottom: headline stating the promise in one line; the price, stated early and plainly, with exactly what's included; three or four features, each written as an entry with a concrete outcome ("Reconcile in 20 minutes, not 2 hours"); a worked example showing real numbers for a typical customer; social proof as a short list of named businesses with one verifiable fact each; and a final summary box — the page's balance sheet — restating price, what's included, and the guarantee. Nothing on the page is allowed to contradict the arithmetic.

Indigo Ledger Landing — Build Template

One landing page = one completed template. Fix the honest argument before designing.

Product: {name} — {one-line promise}

The honest argument (arithmetic shown)

• Costs: {price, exactly as it will appear on the page}
• Replaces: {what the buyer currently pays / does}
• Saves: {figure} — working: {show the calculation}

Visual system

• Ink: deep indigo {hex} / Paper: warm white {hex} / Accent (CTA only): {hex}
• Numbers/headlines: {serif with tabular figures}
• Body: {plain sans}
• Rule: hairline rules separate every row; if it wouldn't fit in a well-kept account book, it doesn't go on the page.
