Sync Master

Shopify App

Sync Shopify inventory straight from Google Sheets.

Bulk update stock and metafields from a spreadsheet. Verify your column mapping with a test connection. Automate it on a schedule. No CSVs, no copy-paste.

Built for merchants who run real catalogs.

  • Multi-location ready
  • Test connection first
  • Scheduled automation
  • Five languages

What it does

Three ways to sync. One source of truth.

Pick the workflow that fits your catalog. Run it on demand, or let it run itself.

01

Sync Selected Items

Paste a list of barcodes or SKUs and update only those rows. Perfect for fast, surgical edits without touching the rest of your catalog.

02

Sync the Whole Sheet

Read an entire spreadsheet and push every row to a Shopify location in one pass. Multi-location updates in a single run.

03

Sync Metafields

Map spreadsheet columns to Variant metafields — only the Variant category of metafield definitions is supported. Normalize values on the fly — dates, booleans, casing, custom rules.

How it works

From spreadsheet to storefront in three steps.

  1. STEP 1

    Connect Google Sheets

    Authorize once. Sync Master reads your sheets — it never writes back.

  2. STEP 2

    Test the connection

    Sync Master fetches the first 3 rows from the cells you configured, so you can confirm the column mapping is correct before running.

  3. STEP 3

    Sync or schedule

    Run it now, or set a daily or monthly schedule and let it handle itself.

Why merchants pick Sync Master

Built around the way real stock teams work.

Test connection first

Test Connection fetches the first 3 rows of your configured cells, so you can verify the column mapping before running the sync.

Scheduled syncs

Daily, monthly, or custom cadences keep your storefront in lockstep with your sheet.

Multi-location

Update one location or every location in a single run.

Smart normalization

Trim, case, date format, booleans, and custom replace rules — no formula gymnastics.

Detailed sync logs

Per-row success and error tracking, so you can audit what changed and when.

Resume on failure

Checkpointed runs pick up where they left off instead of starting over.

Built for scale

Engineered for large catalogs.

Sync Master is built around real-world catalog sizes — tens of thousands of variants, multiple locations, and runs that have to finish reliably.

Batched updates

Inventory writes are batched in groups of 100 and metafields in groups of 25, staying well inside Shopify's API limits.

Checkpointed resume

Every run records its progress. If anything fails mid-way, the next run picks up exactly where it left off — no duplicates, no skipped rows.

Background execution

Long syncs run asynchronously on the server. Close the tab, come back later — the run keeps going and the result is waiting for you.

Live progress & stop

Watch the run advance row by row, with a stop button you can hit at any time. Already-processed rows stay updated.

Pricing

Start free. Scale when you need to.

Three plans. Clear limits. No surprises.

Stop pasting stock numbers by hand.

Install Sync Master on Shopify and run your first sync in under five minutes.
