Deployment and hosting
Both can be self-hosted or run as a hosted service. Self-hosting buys control over data location and upgrade timing, at the price of owning servers, backups and patching. Decide this before comparing features, because it determines who in your business carries the system.
The size of business each assumes
Both scale from small businesses upward, but ERP of any kind assumes defined processes: item masters, tax structures, warehouses and approval chains. A ten-person trading company can run either, and will still spend real time on that structure.
Breadth versus depth
Suites win on breadth. One database holds finance, stock, purchasing and production, which removes a great deal of reconciliation. The trade is depth in individual functions, and sales is the function where that shows up most often, because pipeline work is behavioural rather than transactional.
Implementation effort
Both are partner-led in most cases. Budget for discovery, configuration, data migration and training, and expect the sales module to be scheduled after finance and inventory. That sequencing is sensible, but it leaves enquiry management unmanaged for a while, which is worth planning around.
Channel coverage
ERP suites are document-shaped, not conversation-shaped. Calls and WhatsApp exchanges usually arrive through extensions rather than the core. For Indian sellers this is the largest practical gap, because a great deal of business is agreed in a chat before any document exists.
