FAQ
Inventory & Automated Billing Software questions
Not answered here? Ask us directly.
Is the billing software compliant with Indian GST and e-invoicing rules?
Yes. We build automated GST calculation (CGST, SGST, IGST), HSN code lookups, and direct integration with government e-invoicing and e-way bill portals.
Can it sync inventory with Shopify, Amazon, and offline stores simultaneously?
Yes. When an item sells in a physical retail store, inventory updates instantly across your online Shopify and Amazon storefronts to prevent overselling.
Can warehouse workers use barcode scanners on their phones?
Yes. We integrate camera-based barcode and QR scanning into the mobile web interface, allowing staff to scan items using standard smartphones.
How does it handle batch tracking and expiry dates?
The system enforces FIFO (First-In, First-Out) or FEFO (First-Expired, First-Out) picking logic, alerting staff before perishable inventory expires.
How much does WebMarv charge for custom inventory billing software?
