💬 Frequently Asked Questions

Everything you need to know about Billing Software's enterprise features.

Billing Software utilizes database-level pessimistic locking (lockForUpdate()) on sequence records. This guarantees consecutive, unique sequence generation even when hundreds of users create invoices simultaneously across different terminals.

Yes. Our platform features dual-mode inventory support. High-value equipment can be tracked by individual unique serial numbers (with warranty & service logs), while standard items are tracked by bulk unit quantities.

Absolutely. Non-admin users are restricted to their assigned warehouse ID. They can only view, edit, and invoice stock from their specified location. Global administrators retain master oversight over all warehouses.

Payments entered into the system require admin confirmation before an invoice is marked as fully reconciled. This two-step process guarantees accurate accounting and financial compliance without unverified cash entries.
