Tamarindo design
and writing guide

Use the original artwork

Preserve its proportions, wordmark and three-colour underline. Place it on paper or white. Leave clear space of at least the lowercase “o” height on all sides.

Minimum width: 140px on screen or 35mm in print. The logo should identify the document, not compete with its main message.

Do not reconstruct it

Do not retype, stretch, recolour, add effects or crop the mark. Do not place the supplied paper-backed artwork on a dark surface. A separate approved reverse mark is needed for that use.

Photography and supporting graphics must not borrow identity from other businesses whose folders contain the source media.

One job per slide

Assign a specific question to each slide. Use one main idea and at most three supporting points. Aim for about 45 visible words. More than 70 triggers editorial review; a necessary comparison table may justify an exception.

Read adjacent slides together. If both answer the same question, merge them or move detail into supporting material.

Show calculations on demand

Keep the result, unit and meaning in the slide. Put arithmetic, cell references and assumption detail in “How it is calculated”, with an obvious return action to the same slide.

Material qualifications remain beside the claim or clearly signposted. A cleaner slide must not make a forecast look like a realised result.

Editing test

Can the reader identify the actor, action and financial consequence? Does each sentence add a fact, distinction or necessary explanation? Remove throat-clearing, abstract promises and repeated conclusions.

Prefer “residence” or “residential property” to “home”. Use “IRR” in investor copy; keep the calculation method in supporting notes. Use “Equity” and “Seed Investors”, not “Cash Equity” or “Cash Seed Investors”.

Words that need proof

Fast, secure, confidential, lower cost and no-doc must describe a mechanism or a measured result. Confidentiality does not mean anonymity, no identity checks or exemption from reporting obligations.

Do not claim the lowest rate, universal eligibility, an approved legal structure, committed funding or an enacted tax change without current supporting evidence.

Keep definitions separate

Outstanding principal is a balance at a date. Originations are a flow over a period. A facility commitment is not cash already deployed. A coupon is not an IRR. Reimbursed property costs are not the same as operating revenue.

A replacement facility must not be added to the bridge it replaces. Rounding can create small differences; disclose the basis instead of forcing the source values to fit.

Research hierarchy

Prefer statutes, regulators, central banks, official statistics and provider product terms. Record access date, jurisdiction, eligibility and limitations. A competitor webpage proves its advertised terms, not approval for every borrower.

Keep management assumptions visibly distinct from law. For tax reductions assumed in the model, say that they are model assumptions until legal status is verified.

Diagram rules

• Name every party before using abbreviations.
• Label arrows with money, rights, title or services.
• Separate ownership from operating responsibility.
• Use a consistent flow direction and avoid crossing lines.
• Use dashed lines only when their meaning is stated.
• Provide a text explanation and source reference.

Media rules

• Use real, licensed locations and approved portraits.
• Do not imply stock footage shows Tamarindo assets.
• Use one meaningful image, not decorative stock tiles.
• Keep text readable without relying on the video frame.
• Store the source, licence and attribution with the asset.
• Preserve original assets and editable diagram sources.

Documents

Keep prose left aligned. Use short paragraphs organised around one idea. Give the reader enough context to follow the transaction without needing the slide deck. Tables compare parallel facts; they do not store every sentence.

Keep headings with their first paragraph, avoid orphan lines, and repeat table headers when a table spans pages. Confidential belongs at the top right on each page.

PowerPoint

Use a 16:9 canvas and shared theme colours. Keep all required financial evidence editable. A full-slide screenshot is a visual reference, not an equivalent editable deck.

Inspect exported slides as rendered images and, when available, in PowerPoint. Check fonts, clipping, line breaks, charts and notes. Do not claim native review unless it occurred.

Small screens

• Reflow text and comparisons into a reading order.
• Keep controls at least 44px and inputs at least 16px.
• Respect safe areas in portrait and landscape.
• Provide visible alternatives to swipe-only navigation.
• Keep details, chat and controls from covering content.
• Test at 320,390, 768 and 1440px widths, plus the user’s actual viewport.

Accessible interaction

• Use real headings, buttons, links and labelled fields.
• Maintain visible keyboard focus and logical order.
• Restore focus after closing calculation detail.
• Meet 4.5:1 body-text contrast and 3:1 for large text.
• Do not communicate meaning through colour alone.
• Support 200% zoom and reduced-motion preferences.

Mechanical checks

Flag long slides, repeated titles, vague claims, banned source tabs, missing references, stale figures, inconsistent units and output drift. A flagged sentence needs review; a checklist cannot determine good writing alone.

Editorial decision

Read every title and slide aloud in order. Can a new investor describe the product, customer, parties, markets and funding need? Does the business-model paper explain what the slide deck necessarily omits?
