Got Questions?

Frequently Asked Questions

Clear answers to common questions about SSMS and subscription plans.

What happens if our store loses internet connection during counter rush? +

SSMS features an advanced dual-database replication engine. When the internet disconnects, counter billing seamlessly switches to your embedded local SQLite database with zero interruption or delay. When internet connectivity is restored, all offline transactions, stock decrements, and khata entries automatically sync back to your dedicated cloud PostgreSQL database.

How does license activation work when I purchase a plan? +

When you choose a plan on this page or inside the desktop software, you are directed to the secure Devix Payment Gateway (paymentgateway.devixdevelopers.dev). Once payment is confirmed, the browser communicates directly with your desktop software using the ssms://activate deep-link protocol, immediately unlocking your licensed terminals and provisioning your cloud database.

Can I enforce strict credit limits for customer khata accounts? +

Yes. Every customer profile supports a customizable credit ceiling. When cashiers ring up credit sales, SSMS checks the customer's outstanding balance in real time. If the sale exceeds their credit limit, the system blocks the transaction and requires administrative override, preventing bad debt accumulation.

Does SSMS work with my existing thermal printer and barcode scanner? +

Yes. SSMS supports standard 80mm and 58mm ESC/POS thermal printers (Epson, Rongta, Xprinter, Bixolon, Black Copper) via USB, LAN, Wi-Fi, or Virtual COM. Handheld and desktop 1D/2D barcode scanners work out of the box with zero drivers needed. RJ11/RJ12 automatic cash drawers kick open automatically on invoice printing.

How does Gate Pass (Delivery Challan) dispatch work? +

For wholesale orders and bulk cargo deliveries, SSMS lets you generate official Gate Passes (Delivery Challans). The slip records vehicle registration numbers, driver details, dispatched quantities, and verification QR codes. Security gates can scan the pass before releasing goods from the warehouse.

Can I manage multiple branch stores and godowns? +

Yes. Professional and Enterprise tiers support multi-branch networks. You can manage multiple store locations, track inter-branch stock transfers, assign cashiers to specific outlets, and monitor unified sales from your central management dashboard.
