Hello
I have over 28 years extensive experience with Filemaker Pro and have developed, deployed and maintained many instances from very large and complex down through to small more simple deployments.
Regarding your project, I have read through your outline details and it would be doable, there are a few queries I have:
1. What format is your data currently stored in? You mentioned it can be exported to Excel format, is it currently stored in Excel and if so, is the attached Date Template the current format?
2. Are you currently running Filemaker Pro/Server and if so, which version?
3. For the access side of things, you mentioned issues with customers installing an app, there would be a number of options, including Filemaker WebDirect, PHP/Web Portal or Filemaker Go App, do you currently have a preference regarding that?
4. How many users would you expect to access the database at any one time?
5. Do you have some design ideas in mind (colours, formats, section placements, etc)?
If you would like to send through some additional information on your project as per above, we can confirm a plan and I can provide a more accurate timeline estimate for completion.
Thank you
Darren
