Built from your actual numbers across Amazon, eBay, Walmart and Shopify. Not templates. Not estimates. Computed.
Step 1 — Check your store feesSix deliverables, each computed from your own numbers. None of them is a template you fill in.
The fee calculators are live now, free, and need no account. The rest launches in November — join the waitlist below and we will tell you when.
Where you are doing well, where you are not, and what each gap is costing you. Not opinions. Dollar amounts per product, per platform, per cost line.
Breakeven price for every product. Maximum discount before you lose money. ACoS ceiling. Ad spend limit per unit. The numbers behind every pricing, advertising, and inventory decision you make this week.
Computed from your cost structure, not industry averages. Revenue targets, margin goals, cost budgets — by product, by platform, by month. Your numbers become your benchmarks.
Built from your real costs, your real margins, and your real constraints. Multi-year targets, quarterly milestones, monthly budgets. Updated when your business changes, not when you remember to open a spreadsheet.
Performance vs plan. What moved, what it cost, what to do about it. Structured, scheduled, delivered. You do not have to build it.
Same data means different things depending on whether you are building to sell, extracting cash, or scaling. Every number on your desk is framed against your goal.
You are busy running your business. a1desk handles the financial planning and analysis.
Behind every number: 26 marketplace configurations, 17,000+ fee rules, computed from published rate cards. Each figure is traced to its source. Where a rate card is silent, we say so — we do not fill gaps with estimates. This is the same rigour used to evaluate institutional portfolios, applied to your e-commerce business.

Start with sale price, subtract all fees, factor in return rate. A 5% return rate on a $35 product adds ~$0.05/unit in refund admin. At 15%, it's $0.16. Each product has different rates.
Shopify Payments doesn't return the processing fee on refunds. Basic: (price x 0.029) + $0.30. The $0.30 hits harder on cheaper products.
Surcharges escalate in 30-day bands from 181 days. A compact product at 270 days costs ~$0.08/unit. A bulky product at the same age: $0.75.
Several cost lines sit between gross sales and your deposit: referral, FBA, storage, inbound, refund admin, advertising, aged surcharges, removal charges.
No fixed markup. Raising your Amazon price also increases the referral fee. 15% on $35 is $5.25. Raise to $40 and it's $6.00.
At face value on $50: eBay $6.80 vs Amazon $7.50. But eBay FVF includes payment processing. Amazon referral doesn't.
The same profit figure means six different things. Which one it means for you decides what to do about it.
