FAQ

Frequently Asked Questions

Everything you need to know about GAIN ERP features, multi-industry customization, data migration, and Meta WhatsApp API.

Yes, 100%. GAIN ERP is built as a resilient hybrid system. Your core billing, barcode POS scanning, inventory management, and invoice printing run entirely on your local PC even if your internet is completely disconnected. As soon as connectivity returns, your data automatically syncs with the Web GAIN cloud portal.

GAIN ERP is designed for all major sectors: Wholesale & Distribution (tier pricing, salesman route tracking, customer credit lock), Retail & Supermarkets (1-second POS barcode billing, weigh-scale integration), Manufacturing & Factories (Bill of Materials BOM, raw material issue, job-work challans), Hardware & Electricals (serial number warranty, multi-godown stock), FMCG & Pharma (batch & expiry date alerts), and Textile & Garments (meters/taka, broker Dalali 194H).

We use the Official Meta WhatsApp Cloud API, not unofficial browser scraping tools or pirated extensions. Because it is directly authenticated through Meta Business Manager, your registered business phone number is 100% safe from bans, carries official brand credentials, and sends bills and payment reminders at lightning speed.

GAIN ERP supports all standard business peripherals: 2-inch and 3-inch thermal POS receipt printers (TVS, Epson, Posiflex), laser and inkjet printers (A4 and A5 sizes), high-speed 80/132 column dot matrix printers (continuous stationary), 1D/2D wireless and USB barcode scanners, electronic weighing scales, and cash drawers.

GAIN ERP connects with the official government NIC GST portal. In just 1 click, the software generates compliant Part-A & Part-B e-Way Bills, tempo/vehicle updates, and B2B e-Invoices with digitally signed 64-character IRNs and 2D QR Codes. You never need to enter party GSTINs, pincodes, or HSN codes twice.

Yes! Our technical support team provides complete hassle-free data migration assistance. We can import your customer & supplier ledgers, opening balances, item masters, barcodes, and price lists from Excel, CSV, Tally, Marg, or Busy in less than 2 hours without disrupting your daily sales.

A lightweight secure background service on your master computer securely mirrors ledger queries and summary reports to `webgain.gainsoftwares.com`. You log in using your private credentials from any browser, smartphone, or tablet without needing a fixed public IP.

We offer instant remote assistance via AnyDesk/TeamViewer within 10 minutes, dedicated WhatsApp & phone helplines, and on-site engineers. We provide comprehensive hands-on training for your billing operators, accountants, and warehouse staff.
