Megaventory subscription pricing is mainly based on the number of Megaventory users/seats. Pricing is also based on the number of inventory "Transactions" an account generates.
The base plan supports up to 50k (50 thousand) transactions. If your business generates on average 10 sales invoices a day that's 3650 invoices per year so, you will reach the 50k limit in approximately 13 years. You can increase this limit by purchasing +25k Transactions (so you will again be under the limit for the next 6 years) for a monthly increase in the subscription fee.
