Can I keep records digitally instead of on paper?

Yes. The FDA rule accepts electronic records (21 CFR 117.305) and exempts them from Part 11 unless another regulation requires it.

SQF asks that records be legible, accessible, retrievable and securely stored, in any format. What matters is that the record is made at the time, is indelible (cannot be erased or changed without leaving a trace), and can be found quickly when someone asks for it.
