Spreadsheet or app for reselling inventory?

Short answer: at five or ten items a month, use a spreadsheet. We make the app and we still say that.

Ask any reselling group and the consensus is the same: a spreadsheet does this for free. On the maths, that’s right. Any cost split, any margin, any report you’re willing to build, a sheet will hold it.

What it won’t do is look. Photograph a pile of finds and a sheet gives you a photo, not eight named items.

The rest is what it costs you to keep up. A sheet wants you at a keyboard with a free evening, typing every line yourself. ItemLogue reads the receipt in the checkout line and has the haul itemised before you’re home.

Same arithmetic either way. Your evening goes back to your hobby, your family, or the next sourcing trip.

Find yourself here

It comes down to volume, and to how much time you're willing to put into the books.

Rough numbers, here so you can place yourself. The other half is the time you'd rather spend sourcing, or not spend on this at all.

5–10 items a month

Use a spreadsheet

One platform, a few items at a time. It takes minutes and you’ll remember the details anyway.

Somewhere in between

Depends on the shape

Buying in bulk lots instead of singles tips it earlier. So does selling across platforms, or anything with a return window.

50 in a haul, or 100+ a month

Typing becomes the job

A bin run, or garage sales every weekend. The sheet stops being a record and starts being a backlog.

A lot of resellers are juggling a job, sometimes two, and family responsibilities on top, and that hour at the desk has to come out of something else. Others have the hour and just don’t want to spend it on a spreadsheet.

For someone that busy, spreadsheet time is hard to find. The sheet holds the numbers just fine, it just never gets fed.

A few weeks in, the last few hauls still aren’t typed up. The P&L you can see is missing all of that, and it still counts an item you returned as inventory, so what it does show isn’t right either.

You get that hour back by photographing the receipt instead of typing it in. It reads the numbers, you don’t have to.

That’s what keeps the books current: you update them as you go, not in a sit-down session with a spreadsheet. And current books are ones you can rely on.

Group by where you bought it, then by category, then tap a number to see the items behind it. No setup, no formulas. What’s actually your best sourcing channel, garage sales, estate sales or marketplace? That one you can answer from the couch.

That’s the loop. Less typing, so the books stay current. Current books show you where the money came from, and that tells you where to go next weekend. Do that a few times and you’re buying more of what actually pays.

Buying

A bin run. Fifty items, one price.

In a spreadsheet

Fifty rows, typed. Then split what you paid across them, evenly, because anything smarter isn’t happening tonight.

Realistically the haul sits in bags for a week first.

In ItemLogue

Spread it out, photograph it in batches. ItemLogue reads the items, quantities included.

Type the lot price once and it splits across all of them. Fix what it got wrong, save.

Selling

Someone offers for four items. You have five hundred.

In a spreadsheet

Find four rows out of five hundred. Add up what they really cost, including each one’s share of shipping and tax. Take off the fee and postage. Then decide.

They’re waiting for a reply, so most people just eyeball it.

In ItemLogue

Search the four, add them to one sale, type the offer as the total. It splits, takes off fees and postage, shows what you clear.

On your phone, while they wait.

The other side

Most of this a sheet will hold. Some of it, it can’t.

The record-keeping is all possible in a spreadsheet, often more flexibly. It just doesn’t happen until you sit down and type it. The scanning isn’t a column you can add.

Every row and column is typed

Storage, condition, tags, platform. A sheet holds all of it. You just fill it in yourself, every item.

Photos live somewhere else

You can paste a link per row. Keeping fifty of them pointing at the right picture is what quietly stops.

A date cell stays silent

It sits there being correct while the return window closes. You can script an alert or set a reminder per item, or just have it arrive.

Lot costs need a formula

One price across fifty items, plus shipping and tax on top. Most sheets just divide evenly, and every margin after that is off.

A bin can’t be scanned

No QR label on a bin to show what’s inside, no barcode to pull an item up at the till. That isn’t a formula you’re missing.

Every view is one you write

By shop, then by category, then the items behind the number. A pivot table does all of it, once you know the syntax and keep the ranges right.

Reading it is easy on your phone. Typing on it isn’t.

The mobile apps work fine. Thumbing fourteen rows into a keypad in a queue is what never happens.

The gap widens as you grow. A sheet spreads across tabs and side files. ItemLogue keeps the receipt, the item, the listing and the sale on one record.

Building your own? Use these columns

No catch, no email. Most reselling sheets track the sale price and the purchase price and nothing in between, which is why the margin they show isn’t the margin you got.

  • Item name
  • Where you bought it
  • Date bought
  • What you paid
  • Its share of shipping, fees and tax
  • Condition
  • Where it’s stored
  • Listed price and platforms
  • Date listed
  • Return deadline
  • Sold price
  • Platform fee
  • Shipping you paid
  • Date sold

The one everyone leaves out is the share of shipping, fees and tax. Without it a $15 item that really cost $18.24 looks three dollars better than it was, on every sale.

Signs you’ve outgrown it

  • You buy in bulk lots, so cost per item stops being obvious.
  • You sell across platforms with different fees.
  • You’ve missed a return window, or you’re not sure you haven’t.
  • You’ve stopped entering things the same day.
  • Finding the item takes longer than listing it.
  • A thousand items in, and you couldn’t say which sourcing trips made money and which ones didn’t.

None of those true? Keep the sheet. More on scanning receipts, working out real profit, or the inventory itself.

Most of ItemLogue is free, including unlimited inventory, sales, profit and CSV export. What the plans cover.

Try it against your spreadsheet.

Photograph one haul and see what lands. If the sheet still wins, keep the sheet.
