The Idea
Margin is a financial clarity dashboard built specifically for independent makers. It connects to Stripe, Square, Etsy, and PayPal, lets makers enter their material costs per product line, and answers the one question every maker avoids: Am I actually making money? True margin per item, craft fair ROI, and a monthly P&L that speaks maker — not accountant.
The Problem You Solve
Independent makers are flying blind financially. They know their Etsy revenue. They don't know their profit.
The actual problem is layered:
- Material costs are tracked in notebooks or not at all
- Platform fees (Etsy 6.5% + listing + payment processing) silently eat margin
- Craft fair costs (booth fee, travel, materials, time) are never reconciled against revenue
- Makers can't answer "is my $42 mug actually profitable?" — they've never done the math
- Generic bookkeeping tools (QuickBooks, Wave, FreshBooks) don't know what a glaze batch, a booth fee, or a Etsy listing fee is
The result: makers undercharge, attend money-losing shows, and build businesses that feel busy but aren't profitable. This is endemic across every craft category.
Core Features (MVP)

How to Get First Customers
Cross-community seeding: The prior ideas (Booth, Fairgrounds, Patchwork, Roaster) established a mental model of "SaaS for makers." Post authentically in craft subreddits and Facebook groups — frame it as "I made this for potters like me who never know if they're actually profitable."
The "Real Margin Calculator" free tool: Build a zero-account-required calculator page. Input: product sale price, material cost, platform (Etsy/Shopify/direct), and your rough hourly rate. Output: true net margin with a platform fee breakdown. Goes viral in maker communities. Converts to signups.
Etsy seller forums and Facebook groups: The Etsy Seller Community has millions of members and "am I pricing correctly?" threads are constant. This tool directly answers that question.
Craft fair circuit: Partner with Fairgrounds (organizer tool) to promote Margin to vendors. Natural funnel: organizers use Fairgrounds, vendors use Booth + Margin.
YouTube maker influencers: Potters, woodworkers, jewelry makers with 10k–100k YouTube subscribers regularly make "pricing my work" videos. Sponsor one or offer free Studio access in exchange for honest review.
Revenue Math

Churn is low for financial tools — once you have a year of data, you don't leave. The free calculator creates a steady organic acquisition funnel.
Why This Is Different
No direct competitor at this niche. QuickBooks is generic and costs $35–90/month. Wave is free but not maker-aware. Craftybase exists for product inventory tracking but costs $19–49/month and focuses on cost accounting, not profit clarity with show ROI and channel comparison. None of them have the "was that craft fair worth it?" feature makers actually want.
The insight is that maker financial pain isn't general bookkeeping — it's the specific inability to answer "am I pricing right" and "was this show worth my time." That's a different product than accounting software.
Path to Quitting Day Job
Margin sits at the intersection of every maker category already mapped: pottery, woodworking, cottage food, jewelry, ceramics. It's a horizontal tool across all of them.
At 800 paying customers ($15k MRR), this is a clean exit-the-day-job number as a solo product. That's a small fraction of the millions of active Etsy sellers and craft market vendors.
Expansion levers:
- Tax prep export (Schedule C, hobby vs. business classification) — add-on or tier upgrade
- Integrations with Shopify, WooCommerce, TikTok Shop as those grow
- "Pricing recommendations" AI layer: given your materials + hourly goal, suggest minimum prices by channel
- White-label dashboard embedded in Fairgrounds or Booth (acquisition or partnership)
Risks & Mitigations
Integration maintenance: Etsy, Square, and Stripe change APIs. Mitigate by starting with Stripe only (most reliable) and building manual CSV import as a universal fallback. Charge enough to maintain integrations.
Makers are price-sensitive: The $19/month Maker tier needs to feel obviously worth it. The free tier's real-margin calculator does the heavy lifting — users see the value before paying. A Studio annual plan at $232 lowers perceived cost.
"I'll just use a spreadsheet": Makers say this until they don't. The free calculator converts skeptics because it does the math they won't do in Excel. Once they see the Etsy fee breakdown for the first time, they understand.
Craftybase pivot: If Craftybase adds margin/show tracking, they still have a 2010s-era UI and an existing positioning as "inventory software." Margin owns the financial clarity angle.
Why This Works for You Specifically
You are the target user. As a potter who sells at shows and online, you've felt the financial blindness firsthand: you make something, you sell it, you don't actually know if you made money. Your craft community credibility means posts and outreach land authentically, not as ads.
The technical build is straightforward — OAuth integrations, a solid data model, and clean data visualization. No novel engineering required. The moat is positioning, community trust, and accumulated user data, not technical complexity.
You've already built tooling for the organizer side (Fairgrounds), the vendor analytics side (Booth), and the inventory side (Patchwork). Margin is the financial layer that completes the stack — and the one all those users also need.
First Action
Build the free "Real Margin Calculator" web page this week — no account required, just inputs and a clear output showing true net after material costs and platform fees. Post it in r/Pottery and one jewelry-making Facebook group. Measure signups from the email capture at the bottom ("Want to track this for every product?"). If 50 people sign up in 72 hours, start the full build.
