Sources checked.
SHVL details were checked against the live product on 28 September 2026. Upflow details come from Upflow pricing, cash collection and Xero integration pages on 28 September 2026. "Not published" means we could not find it on the vendor's own pages, not that the feature is missing. Features and prices change, so check the vendor's current pages before deciding.
