AkunaERP imposes no limits on you.
We do not have different pricing if you have more companies, more warehouses, more products or any other marketing tiers.
We do have some volume based charges for our OnDemand offering as these reflect the reality that we need to provide more disk space for your data and your data will consume more space on our backups. However, we make the charge a fair reflection of the cost of providing you the service.
