Why Syntax

A quieter way to run the numbers. Built for sellers who'd rather move stock than wrestle spreadsheets.

FIG 0.1 — SYNC

One synced ledger

Connect eBay and Etsy with read-only OAuth. Orders, payouts and fees flow in automatically — no CSV exports, no copy-paste.

FIG 0.2 — MARGIN

True margin, live

Every marketplace fee, postage label and refund is netted off automatically — so the margin you see is the margin you keep.

FIG 0.3 — WORKSPACE

One calm workspace

Statements, inventory, goals and reports in a single dark, fast interface. Everything in its place, nothing shouting for attention.

Inventory & margins

Know exactly what's
on the shelf — and what
it's really worth.

Syntax tracks every unit against its true landed cost, so stock levels and profit move together in real time.

Landed-cost marginsPostage, fees and tax baked into every SKU's real profit.
Low-stock signalsReorder warnings before a best-seller quietly sells out.
Reconciled to the centInventory value ties straight back to your statements.

Built for real stockrooms

From the back room
to the books.

Syntax was made for people who pack their own orders. The numbers stay honest because they come straight from what actually shipped — not a guess at month-end.
