Yes. Invoicing handles California sales tax (7.25% statewide base rate (including 1.25% mandatory local) plus local district taxes) and the other states where you have nexus. If you or your customers want it, a custom ERP can connect to DBNAlliance through an accredited provider.
Yes. Current language models handle English, Spanish and Chinese well, including mixed-language messages. We still test an agent in each language your customers use before it goes live, and route anything it is unsure about to your team.
Usually one module that fixes the most expensive problem first. For logistics & ports that is often job & shipment costing and warehouse management (bins, put-away, picking). It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
