How B2B Sales Ordering Software Thailand Eliminates Notebook Ordering Errors

It is an enterprise software solution that empowers field sales representatives to access live inventory data, verify customer-specific pricing tiers, check credit balances, and submit purchase orders directly into the central ERP system using mobile devices, completely replacing manual paper-based workflows.

Field reps in Thailand frequently travel through rural areas or industrial zones with weak cellular reception. An offline-first app caches crucial customer, product, and pricing data locally on the device, allowing reps to record orders without interruption and automatically sync with head office once connection is restored.

By integrating with the back-office ERP, the app enforces pre-set wholesale pricing tiers and displays real-time credit status alerts. If a customer exceeds their credit limit or has overdue balances, the software automatically blocks new order creation, preventing unauthorized sales.

An ERP integration project typically requires 25 to 50 man-days of development. At an industry flat rate of 7,000 THB per man-day, the baseline integration cost ranges from 175,000 THB to 350,000 THB. Custom-branded client-facing features are billed on top based on specific project requirements.

Traditional order-taking logs orders for next-day dispatch from a central warehouse. Van Sales, however, treats each vehicle as an active mobile warehouse. Reps carry inventory, sell directly from the vehicle, print physical invoices on-site, and reconcile cash and stock balances at the end of each shift.
