The cost depends on the scope: number of screens, business rules, connections to your existing tools, number of users and level of automation. Since every project is unique, the quote is tailored and discussed according to your priorities.
To put it in perspective: the hours spent every week on manual data entry and standard tool subscriptions accumulated over several years often represent a far higher cost than a tool designed once for your processes.
Modulo IT splits the project into modules: you invest first in the one with the highest return (often automating data entry), measure the gain, then extend if needed — the investment follows your pace.
