Hi, Lori –
Microsoft Access would be one quick way to move to a table-based (vs. the Excel flat file) data storage solution that could later be migrated. It would also be a pretty cost-efficient option as well...

I haven't personally used Access for *this* specific purpose before, but my general opinion is that it could serve as a good garden variety, cost-efficient way to store data in a tabular format until you're able to make a longer-term commitment to a different product.
Several options out there may help you; some even allow you to use it for free. NTEN put a document on low-cost CRM systems and has good comparatives.
The document is a bit old (2017) but still worth reviewing.
I am attaching the document; I hope this helps you guide your decision of a system to use other than excel.
