Frequently Asked Questions

Is BizLyn better than eR4u?

eR4u is a well-regarded retail POS with strong barcode billing, loyalty and eCommerce features. BizLyn builds on those retail capabilities and adds AI forecasting, HR & payroll, GST Composition filing (CMP-08 and GSTR-4), a full reconciliations suite and B2B collaboration. If you need a broader business operating system beyond retail POS, BizLyn is the more complete platform.

Does eR4u support GSTR Composition returns like CMP-08 and GSTR 4?

eR4u is primarily a retail POS and billing platform. It does not have dedicated CMP-08 or GSTR-4 modules for composition dealers. BizLyn natively supports both returns with automatic tax payable calculations, payment recording and a filing history.

Does eR4u have AI forecasting?

No. eR4u focuses on retail operations — GST billing, barcode POS, loyalty and eCommerce. It does not include AI-powered sales forecasting, demand planning, or cash flow projections. These are core features of BizLyn.

Can I use BizLyn if I also sell online?

Yes. BizLyn includes an integrated online store — your own branded website synced with billing, inventory and payments — live in 7 days. It matches eR4u's eCommerce offering while also covering HR, manufacturing, CRM, reconciliations and AI forecasting.
