Yes — MISAll can recalculate cost from the corrected purchase rather than only applying the right figure going forward, so historic margin reports stop being wrong instead of merely improving from today.
This matters more than it sounds. A cost typed in wrong does not just misstate one purchase; it flows into every margin figure for that product since, and into any decision you made on the strength of those figures. Correcting forward leaves you with a report that is half wrong and no marker showing where.
The usual trigger is someone noticing a gross margin that looks impossibly good. Before assuming a data error, check one thing first: whether a tax-inclusive price was entered into a tax-exclusive field. That single mistake inflates margin on every affected line and accounts for most of the "our margins look amazing" cases we are asked about.
Recalculation changes historic numbers, which is correct but worth telling your accountant about before you run it, particularly if a period has already been reported.
This sits in inventory management. Licensing is covered on pricing, and the rest of the questions are in Answers.

Yes. In MISAll the interface language is a property of the user account, not of the installation, so the back-office machine can run in Chinese while the front counter runs in English, Spanish, Arabic, Khmer or Indonesian at the same time.
Because the printer is being asked to render characters that are not in its built-in font table. The fix is to stop sending text and send the receipt as a rendered image instead — MISAll can print in graphic mode, which is why non-Latin scripts come out readable.
MISAll switches to offline mode automatically and keeps taking sales; the transactions sync once the connection returns. You do not have to notice the outage or press anything.
