I’ve tried a few “free” fax apps, and most either limit pages or add branding somewhere. Before choosing one, send a test to yourself and check the received quality, cover-page settings, file storage, and whether the free allowance resets monthly. I’d also avoid anything that makes you upload sensitive invoices without explaining its privacy policy.
For improving small-business workflows, I’ve been looking at
MSI’s self-paced Six Sigma material too. The DMAIC approach is useful for finding where paperwork and approvals keep slowing jobs down.
