How is this different from tracking inventory by SKU?

SKU inventory averages many identical units together. Antique dealing is the opposite — each piece is unique, bought once and sold once, with its own restoration spend. This page gives every one-off item its own record so you see that single piece's true margin, not a blended category average. If you sell repeatable bulk stock, this isn't the right page.

Can Cash Workspace calculate my margin or read my receipts automatically?

No. You enter the acquisition cost, restoration spend, and sale price yourself, and you attach each receipt manually. Cash Workspace does not read or extract data from your documents and does not sync with your bank. What it does is keep all three numbers and their proofs together on one item record so the margin is easy to see and verify.

What if I paid a restorer in cash with no receipt?

Record it anyway as a restoration line — note the date, the amount, and what it was for (for example "French polisher, re-finish tabletop, $37 cash"). A documented note still captures the spend so your per-item cost stays accurate, even when no paper receipt exists.

How do I handle a piece I haven't sold yet?

Keep its record in your active inventory folder with the acquisition cost and any restoration spend logged, and leave the sale price open. The record shows your total invested so far. When it sells, add the sale price and sales receipt, then move it to your sold/YYYY folder.

What about items I'm selling on consignment for someone else?

Those don't belong here. This page is only for pieces you own — bought to restore and resell on your own account. Goods you hold and sell for a third party, where you owe them a payout, fit the consignment and consignor payout records instead.

Acquisition cost records for antique dealers: buy, restore, resell, see the margin

When you deal in one-of-a-kind pieces, there is no SKU and no reorder — every item has its own story and its own math. You paid one price at an estate sale, spent more getting it re-caned, re-veneered, or re-wired, and sold it for a number that felt good but you never quite added up. Cash Workspace gives each piece its own record so the three numbers that matter — what you paid, what you put into it, and what it sold for — live in one place with the proofs attached. The result is a clear per-item margin you can actually trust. This page is about owned one-off inventory you buy to restore and resell; it is not for bulk SKU stock, consignment goods you hold for someone else, or items you manufacture.

The problem

Why per-item margin slips through the cracks

A dealer's "profit" on a piece is rarely the difference between the price tag and the receipt. The restoration spend is what quietly eats the margin, and it tends to arrive in dribs and drabs — a $40 invoice from the upholsterer here, a $12 hardware run there, a cash payment to the French polisher with no paper at all. By the time the piece sells months later, the buy receipt is in a different shoebox and half the restoration costs are forgotten. You end up guessing your margin, or worse, repeating a buy-restore decision that actually lost money.

The acquisition receipt and the restoration receipts get separated, so you never reassemble the full cost of a single piece.
Restoration spend trickles in over weeks — re-caning, re-gilding, parts, courier fees — and small cash outlays vanish without a paper trail.
Months pass between buying and selling, so by sale time you've lost track of what the piece truly cost you to bring to market.
Margin gets estimated from memory, which hides the pieces that barely broke even and the categories that consistently lose money.
Without the buy-and-restore proofs attached to the sale, an item's full cost basis is impossible to reconstruct later.

The per-item workflow

One record per piece, from gavel to sold

Each unique item gets its own record the day you acquire it. You add restoration costs as they happen, then close it out with the sale price. The margin is simply what's left, with every figure backed by an attached document.

1
1. Open the item record at acquisition
The moment you buy a piece, create its record — for example "Walnut tallboy, Marsh estate sale, 04-12." Enter the acquisition cost and attach the proof: the auction invoice, the estate-sale receipt, or a photo of the cash slip. Note the source and date so the buy is locked in before the day's other finds blur together.
2
2. Log restoration spend as it lands
Every time you spend on that piece, add a line and attach the receipt to the same record: the upholsterer's invoice, the hardware-store run, the courier fee, the can of shellac. For cash payments with no receipt, record the date, amount, and what it was for so the spend is still captured. The running restoration total builds itself.
3
3. Record the sale and let the margin show
When the piece sells, enter the sale price and attach the sales receipt or the marketplace payout statement. With acquisition cost and total restoration already on the record, the per-item margin is right there — buy plus restore, subtracted from sale. No reassembly, no guessing.
4
4. File the closed piece by year and review your patterns
Move the finished record into a sold/YYYY folder so your active inventory stays clean. Over time the closed records show which categories and restoration types actually pay — and which pieces you'd think twice about buying again.

Record structure

What to record per piece

These are the fields that turn a pile of receipts into a margin you can read at a glance. Capture acquisition once, add restoration lines over time, and close with the sale.

Item name & description: A specific, findable label — "Edwardian mahogany washstand" or "Seth Thomas mantel clock, c.1890" — not a generic category. This is your one-off identifier in place of a SKU.
Acquisition source & date: Where and when you bought it: estate sale, auction lot #, picker, flea market, private seller — plus the date, so the buy ties to the right receipt.
Acquisition cost: The all-in purchase price you paid, including buyer's premium or lot fees if the auction charged them, with the buy receipt attached.
Restoration line items: Each spend on the piece as its own line — re-upholstery, re-caning, re-wiring, refinishing, replacement hardware, parts, courier — with the supplier and the receipt attached to each.
Total restoration spend: The running sum of all restoration lines, so you always see how much you've put into the piece before it sells.
Sale price & date: What it finally sold for and when, with the sales receipt or marketplace payout statement attached. For unsold pieces, leave it open.
Per-item margin: Sale price minus acquisition cost minus total restoration — the true result for that single piece, recorded for review.
Expense category: Tag each cost line to a product-defined category (acquisitions, restoration-labor, restoration-materials, shipping) so your accountant sees consistent buckets at year end.

Example setup

An example folder layout

A simple structure that keeps active pieces separate from sold ones, with each item carrying its own buy-restore-sell trail. Adapt the folder names to how you talk about your own stock.

Active Inventory/

One record per piece you currently own and are restoring or listing. Example records: "Walnut tallboy — Marsh estate" (buy $220, restoration running $145, not yet sold) and "Brass carriage clock — Hartfield auction lot 58" (buy $90, awaiting re-plating quote).

Active Inventory/Walnut-tallboy-Marsh/

The item's own bundle: acquisition receipt, upholsterer invoice $90, hardware receipt $18, French polisher cash note $37, and progress photos. Acquisition + restoration totals sit on the record.

Sold/2026/

Closed item records moved here after sale, each with buy receipt, all restoration receipts, and the final sales receipt attached — for example "Edwardian washstand" showing buy $140, restore $95, sold $410, margin $175.

Restoration Suppliers/

A reference folder of the trades you use — upholsterer, French polisher, clock repairer, plater — with their rate notes, so you can attach the right invoice to the right item quickly.

Fiscal Year/2026-acquisitions/

A year-scoped view of every acquisition receipt for accountant handoff, kept consistent with the per-item records so cost basis lines up at year end.

Common mistakes

Common mistakes to avoid

Treating a one-off piece like SKU stock — pooling all walnut chairs together — so the individual loss-makers hide inside an averaged number.
Logging only the purchase and the sale, leaving restoration spend uncounted, which inflates every margin you report to yourself.
Letting small cash restoration payments go unrecorded because there's no receipt — record the date, amount, and purpose anyway.
Waiting until a piece sells to gather its costs, by which point the early receipts are lost in other folders.
Filing sold pieces in the same place as active inventory, so your live stock list is cluttered with items that are already gone.
Mixing in consignment goods you're only holding for others — those belong in a payout-owed ledger, not your owned-item margin records.

How it helps

How Cash Workspace helps

One record holds the whole story

Acquisition cost, every restoration line, and the sale all live on the same item record — so the full cost basis of a unique piece is never scattered across separate places.

Attach every proof to the piece

Drag the auction invoice, the upholsterer's bill, and the sales receipt onto the item's record. The documents stay with the numbers they justify, ready for review or handoff.

Consistent expense categories

Tag restoration labor, materials, and shipping to product-defined categories so your spend rolls up cleanly and your accountant sees the same buckets every year.

Fiscal-year folders and export

Close sold pieces into a sold/YYYY folder and export accountant-ready records at year end. It's free, and your buy-restore-resell history stays organized and retrievable.

Jeweler repair & custom order records

The closest sibling for high-value pieces: pairs gold and stone material cost against a multi-stage deposit-and-balance trail on each individual item.

Consignment & consignor payout records

Use this instead when you're holding and selling goods you don't own — it tracks the commission split and the running payout owed to each consignor.

Cash & card purchase receipts by vendor

Group your one-off cash and card buying receipts by store or picker when there's no invoice, so every purchase from a source sits together.

Business expense categories

Set up consistent acquisition, restoration-labor, and materials categories so your per-item costs roll up the same way every year.

Receipt & invoice organizer

The core habit behind this page: capture and file every buy, restoration, and sale document so it's attached to the right item.

Business document organization

The hub for structuring all your finance records into folders — a good starting point if you're building your dealer workspace from scratch.

What this page is and isn't

This is organizational guidance for tracking the cost and margin of pieces you own, not tax, accounting, or valuation advice. Cash Workspace helps you record acquisition cost, restoration spend, and sale price and attach the supporting documents — it does not value antiques, calculate your taxable gain, sync with your bank, or read figures off your receipts automatically. You enter and review every number yourself. For how cost basis and any gains should be treated, consult your accountant.
