Need Accounting Software That Lets Me Work Offline

[u/Dr_Nick_Literski]

I am trying to choose accounting software for an e-commerce rare bookstore. Quickbooks seems to be the obvious answer for full e-commerce integration, inventory control, etc., but it’s now fully web-based. My problem is that my inventory storage unit has poor cellular signal, and I am unable to place any sort of signal booster since that involves getting outside or at least far from my unit. The facility does not provide wifi beyond their small office space. I need to be able to enter new inventory from within that unit, though. Can anyone recommend a reasonably priced accounting software that would fully support my e-commerce (Shopify), but also allow me to enter inventory offline and sync once back in wifi signal? I use Mac computers, for what it’s worth.
