Stock that counts itself — from PO to godown to books.

1. Export your item list from Tally / Busy / Excel and upload it at Items → Import. Only name is required — HSN, GST rate, unit, SKU, barcode, opening stock, and reorder level come along if the columns exist. Sahaya recognises Tally's column names ("Stock Item", "HSN/SAC", "GST %"…) automatically.
2. Check the proposed column mapping on screen — wrong guess? pick the right column from the dropdown. Bad rows show their reason (invalid HSN, unknown GST slab); good rows go through.
3. Existing items are never overwritten — a matching name, SKU, or barcode is skipped, not merged, so nothing you've enriched gets clobbered.

Adding one item by hand: Items → new item — name, HSN/SAC, GST rate, unit, price, reorder level.

1. Open Settings → Locations and add each place stock lives — "Main godown", "Shop counter", "Branch – Indore".
2. From then on every item page shows stock per location, and the Stock home shows each location's SKU count and what's near reorder there.

Raise a purchase order

1. Open Purchase Orders → New PO.
2. Pick the vendor, add line items — quantity, rate, and GST pre-fill from the item master and last costs. Totals compute as you type.
3. Save, then Send it to the vendor. Status moves Draft → Sent.

Receive the goods

1. When the truck arrives, open the PO and click Create GRN — the receipt form pre-fills with whatever's still pending on that PO.
2. Enter what actually arrived, marking each line ok, damaged, or shortfall. Partial deliveries are fine — the PO tracks the remainder.
3. Save. Stock levels and weighted-average cost update instantly, per location.

The bill matches itself

When the vendor's bill arrives (WhatsApp photo, QR scan, or email — nobody types it), Sahaya matches it against the PO and the GRN — the classic three-way match. Quantity or rate mismatches are flagged before anyone pays, and the accounts side sees PO matched on the bill when it's clean.

1. Set a reorder level on each item that matters (item page, or the reorder_level column in your import).
2. The Stock home shows the Reorder board: every item at or near its level, with on-hand quantity and estimated days left based on how fast it's actually moving.
3. Batch-tracked items get an expiry watch too — batches expiring within 30 days are flagged at the top of the Items page.

There's also an as-of-date valuation (for year-end) and a full movement ledger with filters — every in and out, with the voucher behind it one click away.
