FAQ
What hosting fees or external database costs will I have to pay?
None! That is the massive benefit of Google Apps Script. Your web application, database (Google Sheets), and server logic run entirely on Google’s free cloud infrastructure. Unless you scale past standard Workspace quotas or need premium 3rd party APIs, there are zero monthly hosting fees.
Can multiple users log into the ERP or Inventory system at the same time?
Yes. I build custom web interfaces using HTML/CSS/JavaScript that handle multi-user input seamlessly. We can also implement user roles (e.g., Admin view vs. regular Employee view) so staff only see what they are authorized to access.
What are the limitations of a Google Sheets backend?
Google Sheets is perfect for small to medium businesses, with a limit of 10 million cells per spreadsheet. If your enterprise grows larger or requires high-velocity transactions, I can easily modify the script to connect directly to external databases like Google BigQuery or SQL.
Will I be able to edit or modify the code later if needed?
Absolutely. I write clean, well-commented modular code directly inside your project container. You retain full ownership of the application, and any future developer will easily be able to read the documentation and scale the system.
