Your tax appointment is in three weeks. Are your books ready?
Inventory, sales, expenses, mileage, sell advisor, and Schedule C export — all in one dashboard, alongside the LEGO market data you already use to find the deals. Tax-ready by default, not by a panicked weekend in March.
No more juggling QuickBooks Self-Employed, MileIQ, TurboTax, and three spreadsheets. One subscription, one login, one back office — built for the way LEGO resellers actually work.
Why we built it
Reselling LEGO is a real business. The tooling never caught up.
You already track sourcing in BrickPicker. Then you track expenses in QuickBooks Self-Employed. Mileage in MileIQ. Sales across three marketplaces in three spreadsheets. Tax estimates somewhere between a napkin and a panicked April. That's four subscriptions, four sign-ins, and four places for things to fall through the cracks.
My Business is the back office. Same app you use to find the deals, same data feeding both sides. Cost basis flows automatically from the deal you bought. Sale price comes from the marketplace listing. Fees calculate per platform. The expense receipt you snapped at Walmart this morning is on the P&L by lunch.
Tax-ready by default — meaning if you've been logging sales, expenses, and mileage all year, a Schedule C export at year-end is one click. Your CPA loves you. The IRS has nothing to ask about.
What's in the suite
Six tools that replace four subscriptions
Each one is built around the way LEGO resellers actually work — not generic small-business tooling retrofitted for a niche that doesn't fit.
Business Expenses
You snap a photo of the receipt — supplies, fees, shipping, software — and the OCR pulls the merchant, total, and line items. Auto-categorized into Schedule C buckets so a Walmart bin-and-tape run lands in inventory and a USPS label lands in shipping without you thinking about it.
- Photo + email + manual capture
- Schedule C-aligned categories (auto-tagged)
- Per-line itemization, not just totals
- Drill-down search by merchant, category, date
Mileage Tracker
Log scouting trips, store pickups, and supply runs at the IRS standard mileage rate. Address-based: type "Walmart Charlotte" and the autocomplete handles the rest. Multi-stop trips and a saved address book mean you log a clearance run in seconds, not minutes.
- Auto-applied IRS standard rate (we update it when they do)
- Multi-stop trips, distance auto-calculated
- Saved address book (home + frequent stores)
- Year-to-date deduction running on the dashboard
Inventory Tracking
Every set you're holding for resale, in one ledger. Cost basis, days held, target sale price, marketplace listed on, and status (stocked, listed, sold). Aging analysis flags sets sitting too long so you can act before they become dead capital.
- Cost basis, days held, target price per set
- Status tracking: stocked → listed → sold
- Aging analysis flags stale inventory
- Wired into live BrickPicker market value
Sales Ledger
Every sale, with the math done for you. Gross, marketplace fees, shipping, refunds, net, profit, and profit margin — per line. Side-by-side platform comparison shows where you actually make money, Amazon vs. eBay vs. Walmart, after the fees clear.
- Auto fee calculation per platform
- Net, profit, and margin computed per sale
- Side-by-side marketplace comparison
- Refunds and returns flow through cleanly
Sell Advisor
Recommends which set to sell next based on aging, current market price, retirement signals, and your target margin. What-if scenarios let you model "sell now at $X" vs. "hold 60 days at projected $Y" before you list anything.
- Ranked recommendations across your inventory
- Aging × market price × retirement signal
- What-if scenario modeling
- Pulls from BrickPicker's full market data
Reports & Tax-Ready Exports
Monthly P&L dashboard, theme-by-theme profitability, a quarterly tax estimator, and Schedule C export in CSV, PDF, or Excel — IRS-line-by-line with receipt attachments. Your CPA gets a clean handoff. Your audit defense is the export, not a shoebox.
- Monthly P&L: revenue, COGS, expenses, mileage, net
- Theme analytics — what actually makes money
- Quarterly tax estimator (safe-harbor calc)
- Schedule C export with line-item receipts attached
Reports
Monthly P&L, quarterly estimates, and a clean Schedule C
The reports section is where the daily work pays off. Everything you logged through the year — sales, fees, expenses, mileage — surfaces in three views built for the three moments you actually need them.
Revenue, COGS, expenses, mileage deduction, and net income — broken out by month, quarter, and year. Theme-by-theme profitability so you know which categories pull weight and which ones are dead weight.
Safe-harbor calculation plus a self-employment tax estimate and an incremental income-tax projection. Pay quarterlies on time, avoid IRS underpayment penalties, stop white-knuckling April.
IRS-line-by-line breakdown formatted to match Schedule C's structure, with receipt images attached as supporting documentation. Hand it to your CPA and they're done in minutes. Get audited and your defense is one zip file.
A day in the life
Boring book-keeping, automated
The whole point: you don't spend Sunday afternoons reconciling. You spend ten seconds on a receipt, the system does the rest, and the tax-ready picture is always current.
Morning
Scouting trip
Hit three Walmarts on the way to the office. Tap "Start trip," the app logs the route, and the IRS deduction is on the dashboard before you're back to your desk.
Midday
Receipt comes in
Buy a stack of clearance. Snap the receipt, OCR pulls the line items, every set lands in inventory with cost basis, and the supply tape gets categorized as a business expense — automatically.
Afternoon
Sale clears on eBay
Logged in the sales ledger with eBay's fees backed out, your shipping label cost subtracted, and the realized profit posted against the holding's cost basis. Margin shows up on the monthly P&L instantly.
Quarterly
Estimated tax payment
Open the tax estimator. It shows your safe-harbor quarterly payment based on last year's federal tax, plus an SE-tax and incremental income-tax estimate. Pay through IRS Direct Pay; no more April surprises.
Why one app, not four
Stack the math against the alternatives
Each of these tools is fine in isolation — they just don't talk to each other, and none of them know what a LEGO set is. You end up doing the integration work yourself, in a spreadsheet, badly.
QuickBooks Self-Employed
What it covers
Bookkeeping only
What you still need
Doesn't know LEGO. Inventory tracking is generic. No market data, no sell-advisor, no retirement signals.
MileIQ
What it covers
Mileage only
What you still need
Just mileage. You still need separate tools for expenses, inventory, sales, and tax.
TurboTax Self-Employed
What it covers
Tax filing only
What you still need
Reactive. You learn what you owe at year-end. No proactive quarterly estimates, no inventory or expense capture.
Spreadsheets
What it covers
Everything, in theory
What you still need
Drift, errors, and no audit trail. One missed row at year-end is a real tax problem. No receipt attachments. No marketplace fee logic.
BrickPicker Reseller
What it covers
All of it. Plus the LEGO market data.
What it adds
Inventory, expenses, mileage, sales ledger, sell advisor, monthly P&L, quarterly tax estimator, and Schedule C export — wired into LEGO market memory, retirement signals, and the arbitrage tools you already use to find the inventory in the first place.
Replaces a stack of subscriptions that don't know your business — for less than the stack costs and with a deal-finding platform on top.

This is not tax advice. Always consult a CPA.
- •We are not a CPA, a tax preparer, or a registered tax advisor.
- •The quarterly tax estimator runs standard public formulas. It is a calculator, not a tax engine.
- •State and local taxes are not modeled. Filing status edge cases, dependents, retirement contributions, health-insurance deductions, depreciation rules, and home-office allocations are not modeled.
- •Always consult a licensed CPA or Enrolled Agent before filing. Use this tool to keep books clean and pay quarterlies on time — not to replace professional tax advice.
My Business is bookkeeping software. It calculates standard public formulas, surfaces what your CPA needs at filing time, and keeps your books clean year-round. It does not file your taxes for you, nor does it replace professional advice for anything beyond a basic Schedule C situation.
