For multi-channel resellers

eBay plus Amazon plus Mercari. One set of books. Zero chaos.

Multi-channel resellers end up with five sets of broken records — one per platform. Profit Hawk was built multi-channel from day one. One COGS lot, every channel, one unified ledger.

  • eBay fully synced today — reconciliation, COGS, fees, and payouts
  • Mercari and Poshmark on the near-term roadmap
  • One profit number across all channels — no manual consolidation

Five marketplaces, five 1099-Ks, and a CPA who has no idea what to do with any of it.

The multi-channel reseller's tax nightmare is real: eBay sends one 1099-K, Amazon sends another, Mercari sends a third — all reporting gross sales before fees, before returns, before chargebacks. None of them match your bank deposits. Your CPA charges three extra hours sorting it out. Profit Hawk reconciles all of it into one unified picture — real revenue, real fees, real profit — across every channel, ready for your tax preparer in one package.

One COGS lot, any channel the item sells on.

You sourced 40 vintage shirts for $80 — $2 per shirt. You list 20 on eBay, 10 on Poshmark, 10 on Mercari. The cost basis is the same lot regardless of channel. When each shirt sells, Profit Hawk records the channel-specific fees and net profit. You'll know which marketplace actually makes you more money per item after their fee structure.

Channel-by-channel fee intelligence.

eBay charges a percentage that varies by category. Poshmark charges a flat $2.95 under $15 and 20% above it. Amazon FBA adds pick-and-pack on top of the referral fee. Mercari charges 10% plus a payment processing fee. Profit Hawk knows every fee table and applies the right one — so your margin comparison across channels is apples to apples.

One Tax Pack. Every channel.

At tax time, your CPA gets one package: total revenue by channel, total COGS, total fees by channel, net profit, and a reconciliation of your 1099-Ks against your actual taxable income. They see where every dollar came from and where every deduction belongs. No more 'what's this Amazon deposit?' conversations.

Multi-channel questions.

eBay is fully live with complete reconciliation. Other channels are manual import today and sync integrations on the roadmap.
Yes. Start with eBay. Your data format doesn't change when new channel syncs launch — you just connect them.
The lot tracks the total inventory. When an item sells on any channel, you mark it sold from the lot. The COGS allocates correctly regardless of which channel moved it.
Yes. Profit Hawk shows your gross sales per channel, subtracts marketplace-collected sales tax, fees, and refunds to arrive at your actual taxable income — and compares that to what each 1099-K reported.
