Questions
Are these tools really free?
Yes. The calculators and label makers are included on every plan, including the free plan. You need a BoostBizTools account to use them.
Do the calculators know my marketplace’s fees?
No. Fees change often and differ by category, so you enter them from your rate card or a recent settlement. The result is an estimate; your marketplace statement is final.
Will the barcodes scan?
Bars are drawn as sharp vector lines at a printable width with a clear margin on each side. Print at 100% (actual size) and scan a test label before printing many. A code that is too long for the label is refused rather than printed too small.
Can I make my own EAN-13 numbers?
No. EAN-13 numbers for retail products come from GS1 India. Made-up numbers can belong to someone else’s product. For your own SKUs, use Code 128.
Does the MRP tag make my product compliant?
The tool prints what you enter. It does not check that your label is complete for your product. Food, cosmetics, drugs and some other goods have extra labelling rules; check them for your category.
