Basics
Free GST Invoice Maker & Profit Calculators on Bikwao
Running a wholesale trading, manufacturing, or surplus stock clearing business in India involves constant mathematical calculations: working out reverse GST figures, splitting CGST and SGST on odd amounts, calculating margins against bulk lot MRP, and generating clean tax invoices for buyers.
Small traders and MSMEs often struggle with expensive, complicated accounting software just to generate an occasional B2B invoice or verify a supplier's quotation.
To help traders make faster, smarter business decisions, Bikwao provides a suite of completely free business utility tools. You can access all of them immediately in the Bikwao free business tools hub, with zero software installation, no credit card, and no mandatory registration.
1. Instant GST Invoice Maker
Whether you are dispatching a full truckload of textiles and fabrics or clearing surplus packaging materials and boxes, issuing a valid GST invoice is legally required under Section 31 of the CGST Act.
Features of the Bikwao GST Invoice Generator
- Automatic State & Tax Detection: Enter the supplier's state and recipient's state. The tool automatically decides whether to apply intra-state CGST + SGST (50/50 split) or inter-state IGST.
- Round-Off and Odd-Paise Handling: Splitting odd-paise amounts (like 5% GST on Rs 123.45) frequently causes rounding discrepancies between tax ledgers. The invoice engine balances CGST and SGST down to the exact paisa so books reconcile cleanly.
- Print & PDF Export: Fill in your business name, GSTIN, invoice date, HSN codes, and line items. With one click, generate a clean, professional, print-ready PDF invoice ready to email or attach to goods.
- Zero Data Harvesting: Your customer details, pricing, and business transactions are processed directly in your browser session. Bikwao never stores or mines your client invoices.
2. Inclusive and Exclusive GST Calculator
B2B negotiations often involve shifting between "tax-inclusive" and "tax-exclusive" price quotes.
For example, a seller may quote Rs 450 per unit "all-inclusive" for an overstock batch of electrical fittings. To know your input tax credit (ITC) and base purchase price, you must calculate backwards:
$$\text{Base Price} = \frac{\text{Inclusive Amount}}{1 + \left(\frac{\text{GST Rate}}{100}\right)}$$
$$\text{GST Amount} = \text{Inclusive Amount} - \text{Base Price}$$
The Bikwao GST Calculator allows you to toggle between:
- Add GST (Exclusive to Inclusive): Enter your base rate and select the GST slab (0.1%, 1.5%, 3%, 5%, 12%, 18%, or 28%). It instantly calculates the exact CGST, SGST, IGST, and final gross billing amount.
- Remove GST (Inclusive to Base): Enter the final quoted amount to reveal the true base taxable value and the embedded tax amount eligible for input tax credit.
3. Stock Lot Profit & Margin Calculator
Surplus lots and inventory clearance deals carry unique cost structures. A deal that looks cheap on a per-unit basis can quickly become unprofitable once you add handling, transit insurance, freight, and expected defect percentages.
The True Cost Formula in Surplus Lots
$$\text{Landed Cost per Unit} = \frac{\text{Lot Purchase Price} + \text{Freight} + \text{Handling} + \text{Packaging}}{\text{Total Units} \times (1 - \text{Expected Defect Ratio})}$$
The Bikwao Lot Profit Calculator helps you:
- Factor in transport, local loading, and unloading charges.
- Adjust for expected defect or unsellable damaged units (e.g., 5% damage allowance).
- Determine minimum wholesale selling price to secure your target return on investment (ROI).
- Compare buying by weight versus selling by retail piece.
4. Free Unit Converter for Industrial Trade
Industrial traders deal across multiple measurement units depending on the commodity:
- Textiles: Meters, yards, kilograms, running meters, and ounces.
- Metals & Scrap: Metric tonnes, quintals, kilograms, and pounds.
- Chemicals & Liquids: Litres, imperial gallons, drums (200L barrels), and kilograms based on specific gravity.
Bikwao’s unit converter provides quick conversions across Indian trade benchmarks, preventing costly calculation mistakes when converting factory lot manifests into retail billings.
Take advantage of these free utilities today by visiting the Bikwao business tools section. If you are conducting transactions with new counterparties, always pair these tools with our safe trading guidelines to verify GSTIN status and inspect goods prior to payment.
