INSTICA / OPERATOR SOFTWARE FOR INDEPENDENT SELLERS

Know what you own. What it cost. Where it sold.

Built for the operator running eBay and Shopify side by side. Discogs and Etsy when the inventory calls for them.

02 / THE OPERATOR PROBLEM

You don’t have a sales problem. You have a ledger problem.

The sale happened at 4:12pm. The oversell happened at 4:13pm, because two ledgers disagreed about a quantity that hadn’t moved in a week. Every reseller who has been at this for more than six months has felt this — not as a business risk, but as a Tuesday afternoon stomach drop.

The problem isn’t the sale. It’s the three seconds between the sale and the update — and the fact that those three seconds are being managed by a spreadsheet, a sticky note, and someone’s memory. Instica collapses those three seconds to zero. That’s the whole product.

04 / WHO USES IT

05 / WHAT A TUESDAY LOOKS LIKE

A sale at 4:12pm.
Every listing updated by 4:12:03.

It’s 4:12pm on a Tuesday. A buyer in Hamburg pays for a 1973 pressing of Innervisions on eBay. Three seconds later, the same record disappears from your Shopify storefront, your Discogs listing is delisted, and your iPad shows the new cost-basis math: $42 in, $78 out, $36 booked. You did nothing. You were eating a sandwich. That’s the entire pitch. The rest of this page is just proof.

06 / THE MECHANICS

Three things running quietly in the background.

QUIET SYNC

Background reconciliation between eBay and Shopify. No autoplay, no progress bars, no notifications unless something needs you. Conflicts surface in a single inbox.

LEDGER

Every listing event — created, edited, listed, sold, refunded, ended — is a row. Export to CSV or push to Sheets. Your accountant gets one file.

FIELD CAPTURE

iPhone app: photograph, voice-note, push to draft. The desk app finishes the listing. The phone closes.

07 / PRICING

Four tiers. Three prices. One for hands-on conversations.

08 / WHAT WE GET RIGHT THAT ONE-SIZE-FITS-ALL TOOLS DON'T

Eight moves. Each of them small. Together, they're the whole product.

Built for the operator, not the pitch deck.

One ledger, not four.

eBay, Shopify, Discogs, and your own records agree on the same count. No reconciliation spreadsheet. No Sunday morning panic.

WRITES TO 3 CHANNELS READS FROM 3 CHANNELS DISAGREES WITH 0 OF THEM

Cost basis, stamped.

Every item enters with what you paid, so you always know if you're making money. Stamped at acquisition, not reconstructed in April.

STAMPED AT INTAKE IMMUTABLE AFTER SURVIVES SCHEDULE C

Nine seconds, not three hours.

An eBay sale at 4:12pm decrements Shopify by 4:12:09. The buyer in Vancouver never gets a shipping confirmation for something already on its way to Osaka.

Photo-first intake.

Shoot on iPhone. Instica pulls metadata, suggests tags, strips backgrounds. The listing writes itself, you confirm.

EXIF EXTRACTED BACKGROUND: REMOVED DRAFT: AUTO

P&L that travels with the item.

Every item carries its cost, fees, and net margin. Export the full ledger in one click — no upgrade required, no email gate.

PER-ITEM COGS PER-ITEM NET EXPORTABLE: ALWAYS

Built to be exported.

Your data leaves the same way it came in. One CSV, no extraction fee, no deprecation notice, no "premium plan required."

CSV: 12 COLUMNS JSON: ALSO GATED: NEVER

Keyboard-first.

Bulk-edit 200 items in three keystrokes. The kind of detail that doesn't fit on a screenshot but matters at 11pm in January.

⌘B BULK ⌘E EXPORT ⌘? THE REST

Honest at the edges.

When eBay rate-limits us, you see it. When a sale conflict happens, you decide. We tell you what's broken before you find out from a buyer.

09 / WHAT INSTICA DOES IN APRIL THAT IT DOESN’T DO IN OCTOBER

The work changes with the season. The ledger doesn’t.

Reselling has a calendar. Most software pretends it doesn’t.

JANUARY

Schedule C season

Your accountant needs cost basis for every item sold last year. Instica exports it, stamped at acquisition, ready to hand over. No archaeology.

Instica in January — Schedule C export

APRIL

Warm restock

Estate sales and thrift runs restart. Intake volume spikes. Every new item gets a cost-basis stamp and a cross-channel listing in one pass.

Instica in April — warm restock season

AUGUST

Death pile audit

The pile that hasn’t moved since March. Instica flags inventory by age and last-listed date so you know what to relist, reprice, or donate.

Instica in August — death pile audit

NOVEMBER

Q4 surge

Sales velocity doubles. So does the risk of overselling. Sub-3-second sync means Q4 runs at full speed without a single quantity conflict.

Instica in November — Q4 surge

10 / FROM THE FOUNDERS

We built Instica because a record sold twice in one weekend. The apology email at 11pm was the last one we’d send.

11 / FROM ZERO TO ONE LEDGER

01

Connect

Ninety seconds, no API keys, no copy-pasted tokens. OAuth with eBay or Shopify. Under 4 minutes, no passwords stored.

02

Import

We read what’s already there. We don’t write a thing until you say so. Drafts, sold history, photos, fees — imported in one pass.

03

Sync

eBay sale at 4:12:00. Instica detects at 4:12:01. Shopify updated by 4:12:03.

Vendoo, List Perfectly, Sellbrite are real products with real customers. Here’s where Instica is different and where it isn’t.

READ-ONLY BY DEFAULT

We request the narrowest scopes the APIs allow. We don’t touch payouts, payment methods, or buyer PII.

14 / DATA, IN THREE PLAIN SENTENCES

Three things we will not do.

We will not sell your inventory data, sales data, or behavioral data to any third party — advertising networks, data brokers, or otherwise — under any circumstance.

We will not use your data to train machine-learning models without your explicit, per-operator opt-in.

We will not make it harder to export or delete your data as the product grows. The CSV button and the delete button will always be accessible from your account page without a support ticket.

Two weeks. Your inventory. No card.
