Run every counter, shelf, and branch from one system

Not if it is your own connection that is down — selling requires a connection and there is no offline path in the POS. Worth separating from the other outage people mean by this question: if your line is fine and KRA is unreachable, the sale completes as normal and the transmission retries on its own until it lands, so a KRA outage never stops the counter. For your own connectivity, treat it as a continuity question and plan a backup line the way you would a backup generator.

The shift close states expected takings by payment method; you match the M-Pesa till statement against system-recorded mobile payments per shift, and variances are logged by name. The routine takes about 20 minutes per counter per day.

Yes — item lists are standardized and merged during onboarding, then branches connect one at a time, each going live at a stock count. Clean master data is most of the migration work, and it pays back immediately in shared reporting.

Partly, and the part it does not do is worth knowing before you decide. Credit sales with customer accounts and credit limits run alongside cash-and-carry, and margin is reported per item. What does not exist is a price list: there is no customer price tier and no per-customer pricing, so a wholesale price is entered on the line at the time of sale rather than applied automatically from the account. For a shop with a handful of trade customers that is workable. For one running a real trade-price book across hundreds of accounts, it is the question to press us on.
