eBay Whatnot PWCC COMC MySlabs Manual entry

You're running a real business on a spreadsheet that lies to you.

A $400 sale isn't $400. eBay took $53. The label cost $9. You forgot the grading fee. Your "profit" is fiction — your inventory's a guess — and tax season is a panic attack. There's a better way.

How it works

Up and running in
under two minutes.

STEP 01

Import your listings

Drop in your eBay or Whatnot active-listings CSV. Every listing lands as inventory — quantities and prices intact, one card per listing, no duplicates.

STEP 02

Drop your sales CSV

Export your monthly sales report and drop it in. Period auto-detected. Every fee parsed. Net profit calculated to the penny, per platform.

STEP 03

See profit, forecast, rank

Real P&L per month and per card. Projected revenue on what you're holding. Smart insights on what to fix. And your rank, climbing.

Built for serious sellers

See real profit after every single fee.

Gross sale minus eBay fees isn't your profit. CollectingHQ subtracts platform fees, payment processing, shipping labels, grading costs, and your cost basis — automatically. The number you see is the number you actually keep.

  • Accurate cost basis down to the cent
  • Every fee category tracked and categorized
  • Real margin %, not a hopeful guess

Your inventory, working as a forecast.

Every card you hold becomes a live portfolio. See total units, cost in hand, listed value, and exactly how much you'll collect after fees if it all sells. Aging alerts flag the cards sitting too long. It's a CRM for your shelf.

  • Projected revenue & profit on everything held
  • Quantity-aware: one card per listing, ×qty tracked
  • Aging alerts for inventory held 60+ days

eBay and Whatnot in a single financial view, plus an Overall tab that combines everything. Then the Insights engine reads your data and tells you what's working: your top earner, fees eating margin, stale inventory, your best flip, and what to fix next.

  • Separate eBay + Whatnot dashboards, plus combined
  • Smart insights on performance, fees & aging
  • Period-by-period comparison, any month

Why I built this
K
"I run a mystery pack business out of Brampton. I got tired of guessing whether I was actually profitable — so I built the tool I wished existed. Now I'm sharing it with every serious flipper who's sick of broken spreadsheets."

No card required for the trial. Sign up with email and get 7 full days. You're only charged if you continue after the trial ends.

Yes — as long as your subscription stays active. Founding members lock in $4.99 permanently. Cancel and resubscribe later and you'll pay the current rate. So once you're in, stay in.
What platforms do you support?
eBay CSV (sales and active-listings reports) and Whatnot CSV import fully. PWCC, COMC, MySlabs, and direct sales can be entered manually. More platform imports are coming based on what users request.
Does it track inventory, not just sales?
Yes. Import your active listings and every one becomes held inventory with its quantity and list price. You get a live portfolio with projected revenue, profit forecasts, and aging alerts — plus editable listings and one-click updates.
Is my data safe?
Your data is encrypted, isolated to your account, and exportable anytime. We never sell or share user data. It's your business — it stays yours.
What sports and cards does it work for?
All of them. Basketball, football, baseball, hockey, soccer, Pokémon, and any TCG. The financial tracking is category-agnostic — it works for any card or collectible you flip, including sealed and mystery packs.
