iii.Pillar three

Math

"Revenue is vanity. Cash is reality. Profit is sanity."

Most starting brands fail at one of two numbers, and they don't know which one. This is the pillar that separates founders from hobbyists. We pull your real data and run it through the four math frameworks every Shopify owner should know — marketing math, accounting math, unit economics, and inventory math. By the end, you can defend or kill any spending decision with a number.

section 01

Marketing & Conversion

If your conversion rate is below 1%, more traffic just means losing money faster. We dig into your social media, ad, and on-site data to find which step of the funnel is actually broken, and how much your business should be willing to spend per visitor to keep going.

01.

Social Media Data Analysis.

A read of your post-level data (saves, shares, profile clicks, link clicks) to identify which content type is actually moving people toward purchase and which is just generating likes. We separate vanity engagement from buying signals.

02.

Conversion Rate Calculation.

We benchmark your conversion rate against your specific category (not the meaningless "industry average" of 2.5%) and break it down by traffic source, device, and landing page. Output: a single number that tells you whether to fix conversion or fix traffic next.

03.

Funnel Rate Analysis.

Step-by-step funnel: ad/post → site visit → product page → ATC → checkout → purchase. We find the leakiest step and quantify what fixing it is worth in dollars. Most starting stores leak hardest at product page → ATC. Yours probably does too.

section 02

Accounting Analysis

Most starting founders track revenue and ignore profit until something breaks. We rebuild your basic accounting picture so you know what you make, what you keep, and what each marketing dollar is actually returning.

01.

Cost Analysis.

We separate fixed cost, variable cost, and the hidden third bucket most founders forget — founder labor priced at zero — and rebuild your true cost-of-goods picture. You'll often find one cost line item is silently eating 40–60% of your contribution margin.

02.

Basic Cashflow & Net Profit Calculation.

Cash flow is the lifeblood of business. We give you a founder-readable monthly P&L and 90-day cash projection. No accounting jargon, no fancy software. Just the three numbers that decide whether you can keep operating next month.

03.

ROI Audit.

A channel-by-channel ROI review — including the channels you don't think you're spending money on but actually are (your time, your tools, your auto-renewing subscriptions). Output: a kill list and a double-down list.

section 03

Unit Economics

This is the most important math any DTC founder will ever do, and almost nobody under $5K MRR has run it correctly. We build your unit economics from the ground up so you know exactly how much you can pay to acquire a customer and how much each one is worth.

01.

CAC vs. LTV Loop.

We calculate true CAC (including the costs you're not counting) and realistic LTV (with your actual repeat rate, not Shopify's optimistic projection). Output: a CAC ceiling that tells you the most you can spend to acquire a customer and still survive.

02.

AOV (Average Order Value) Analysis.

AOV is the easiest lever you're not pulling. We map your AOV by SKU, traffic source, and buyer cohort, then identify two structural moves (bundle, upsell, threshold) that lift AOV by 10–25% without changing your traffic or conversion rate.

section 04

SKU & Inventory Math

If you're selling 30 products and 80% of revenue comes from 4, the other 26 are taxing your operations, your photo time, your ads, and your decision-making. We run an honest cut.

01.

ABC Analysis.

We rank your SKUs by revenue contribution and split them into A (your real business), B (supporting cast), and C (tax on your time). The deliverable is a focused SKU strategy and a clear answer to "should I add this new product?" for the next 90 days.

Key takeaways

A founder-readable financial reality check in 4 documents:

  • Your funnel-leakage map (where exactly you're losing dollars per step).
  • Your true CAC ceiling — the most you can pay to acquire a customer.
  • Your 90-day cash projection + monthly P&L (no jargon, no fancy software).
  • Your ABC-ranked SKU list — A (your real business) / B (supporting) / C (kill candidates).

Mindset shift You stop asking "am I doing well?" and start answering "what does my next dollar do for me?" You'll be able to defend or kill any spending decision with a number — including the decision to keep going at all.
