GST Billing · Inventory · Karigar · Metal Ledgers

Software built for jewellers,
not adapted for them.

Most accounting software treats jewellery as one industry among twenty. Koshavo is built around fine weight, wastage%, karigar work-in-progress, and gram-for-gram metal ledgers from day one — with GST and Cash billing running side by side.

One system, from billing to bullion

Every module below exists in the running app today — not a roadmap slide.

GST + Cash Dual-Mode Billing

Formal GST invoices with CGST/SGST/IGST and e-invoicing, or quick Cash bills — on the same customer, switchable per bill.

Karigar Metal Tracking

Issue metal to an artisan, track work-in-progress in grams, and reconcile finished goods back into stock automatically.

Exchange & Melt Workflow

Old material received → sent to bullion → melt result recorded → PURE-GOLD/PURE-SILVER stock updated, with gain/loss tracked at every step.

Metal Ledgers, in Grams

Per-customer and per-vendor Credit/Due balances tracked in gold and silver grams — not just rupees — with full running history.

Rate-Lock Deal Booking

Let customers commit to buy or sell gold and silver at today's rate for a future date — partial fulfillment and auto-expiry included.

Multi-Firm, 6 Themes

Run several firms from one install, each with its own encrypted database, and pick from six built-in appearance themes.

Offline-First Desktop

Runs fully offline at the counter with a local database, and syncs deals and customers to the Koshavo Android companion over Wi-Fi.

GSTR-1 / GSTR-3B Filing

Validate, preview B2B/B2CS/B2CL, export JSON or Excel, and mark a period filed — with the app blocking edits to filed periods.

Built around jewellery, not bolted on

What changes when the software is jewellery-first

Generic GST software can be configured for a jewellery shop. Koshavo starts there.

General accounting / billing software

  • Weight, wastage% and purity are custom fields you configure yourself
  • Customer balances are tracked in rupees only
  • No concept of a karigar or metal work-in-progress
  • Old-material exchange handled as a generic credit note

Koshavo ERP

  • Fine weight, wastage% and HUID are native fields on every invoice line
  • Every customer and vendor has a live gold-gram and silver-gram ledger
  • Karigar issue/receive with running metal WIP balance built in
  • Exchange items flow through melt to PURE stock with gain/loss tracked

Questions

Frequently asked questions

Does Koshavo handle GST invoicing and e-way bills?+

Yes. Koshavo creates GST invoices with CGST/SGST/IGST, supports HUID, and prepares GSTR-1 and GSTR-3B for filing directly from the Reports module.

How is wastage% used in calculations?+

Every invoice line computes fine weight from gross weight, less weight and wastage%. Purity% is stored as a classification label and doesn't affect the fine-weight formula.

What does "karigar tracking" actually track?+

When metal is issued to an artisan, Koshavo records it as work-in-progress. When finished goods come back, they're added to stock and the karigar's balance updates automatically — no manual reconciliation.

Does Koshavo work without an internet connection?+

Yes, billing and day-to-day operations run fully offline on the desktop app. An internet connection is only needed for license verification and optional updates.

Can I run more than one shop/firm from one install?+

Yes. Koshavo supports multiple firms, each with its own encrypted database, switchable from a single desktop installation.

What happens to old material/exchange items customers bring in?+

Old material is logged against the bill, sent to bullion, and once the melt result is recorded, the refined metal is added to Pure Gold/Pure Silver stock — with gain or loss tracked at every step.

Can Koshavo be customized to how my shop already works?+

Yes. Billing mode (GST/Cash), item fields, labour and wastage rules, print formats, and appearance theme are all configurable per firm — and our team tailors the setup and plan to your shop's size and workflow during onboarding.
