└───────────────────────────────────────────────┴───────────────────────────────┘3 Easy Ways to Add Items to a Bill
- Barcode Scanner (Fastest):
Simply pick up any item and scan the barcode. The product appears in the cart immediately. Scan the same item twice to increase quantity to 2. - Search by Name or SKU:
Click the search box (or press the/shortcut key) and type a few letters of the product name (e.g., "amul butter" or "parle"). Select the item from the dropdown list. - Touch Category Tiles:
For items without barcodes (like fresh bakery buns, samosas, or loose potatoes), tap on the category tile and touch the item to add it.
Everyday Counter Actions
Changing Quantities & Weighed Items
- Click the
+or-buttons next to any cart line, or type the exact quantity. - For weighed produce (like fruits or vegetables), enter decimals like
1.750kg. If you have a connected digital scale, the weight automatically fills in!
Giving Discounts
- Item Discount: Click the discount tag next to a specific item to give a percentage (e.g.
10% off) or flat rupee discount (e.g.₹20 off). - Bill Discount: Click Add Bill Discount at the bottom of the cart to apply a special discount to the entire purchase.
Handling Counter Rushes: Hold & Recall Bills
Imagine a customer is at your counter with 15 items in the cart. Suddenly, they say: "Wait, I forgot my wallet in my scooter, give me 2 minutes!"
Without MEGSTAT POS, the cashier is stuck waiting while other customers get annoyed.
- Click Hold Bill: The current cart is safely saved with a ticket number, and the screen clears instantly.
- The cashier bills the waiting customers.
- When the customer returns, click Recall Bills, tap their ticket, and resume billing right where they left off!
Indian GST Made Completely Simple
You never have to calculate tax percentages manually or guess which tax rule applies. MEGSTAT POS takes care of all GST calculations in the background based on official Indian tax rules:
1. Same-State Sales (Intra-State Supply)
If your store is in Maharashtra (State 27) and you sell to a local customer:
- The system automatically splits the GST 50/50 into CGST + SGST.
- Example: On an item with 18% GST, the bill displays 9% CGST and 9% SGST.
2. Other-State Sales (Inter-State Supply)
If you ship goods to a customer or business in Karnataka (State 29) or any other state:
- The system automatically bills the tax as 18% IGST (Integrated GST).
3. Tax-Inclusive vs. Tax-Exclusive Pricing
- Tax Inclusive (Retail / MRP): In grocery and apparel stores, prices on shelf tags typically include GST (e.g., MRP ₹100). MEGSTAT POS back-calculates the taxable value and tax portion cleanly so the customer pays exactly ₹100.
- Tax Exclusive (Wholesale / B2B): Wholesale stores quote prices before tax (e.g., ₹100 + 18% GST = ₹118). The system adds the tax cleanly at checkout.
4. B2B Invoices with Buyer GSTIN
For business buyers who need input tax credit (ITC):
- Select or create the customer and enter their 15-character GSTIN.
- The system automatically verifies the business name and prints an official GST Tax Invoice with HSN codes, Buyer GSTIN, and reverse-charge indicators.
Accepting Payments (Split Tender)
Customers pay in different ways. MEGSTAT POS supports any combination of payment methods on a single transaction:
