Hey Product Hunt community! 👋

We’re thrilled to introduce FIT Apps (https://fit-apps.dev).

Why we built this:

As operators running our own high-volume 4,000+ SKU store (Bikenbiker) on Shopify, we were constantly frustrated by two things:

1. Legacy sync tools that charged aggressive per-order fees (costing hundreds of dollars on busy sale days).

2. Clunky off-the-shelf plugins that broke whenever multi-warehouse stock, split fulfillment, or statutory tax rules (like Indian GST & Legal Metrology) were required.

So our engineering team built FIT Apps—a cloud-native suite of 10 modular Shopify apps running on Google Cloud Run:

• FIT Zoho Sync: Sub-2-second bidirectional sync between Shopify & Zoho Inventory/Books with automated Indian GST/HSN splits.

• FIT Listing Master: Bulk Legal Metrology (LMPC) compliance declarations, 1-click variant bundles, and vehicle fitment matrices.

• FIT Inventory Sync: Ingests supplier stock updates directly from incoming Gmail CSV attachments and Google Sheets.

• FIT POS & Warranty Guard: High-speed barcode POS registers & customer serial/warranty registration portals.

While our public Shopify App Store listings are in final review, we are onboarding merchants directly today with Done-For-You Custom Store Integrations!
