Field notes
HarBill’s example models a Friday hotpot bill: named diners, item-specific participation, 10% service charge and 7% VAT, with per-person totals and QR markers. HarTrip is described for expenses paid by different people over multiple days; participants add records through one shared link, then receive a settlement showing who should transfer money to whom. The maker identifies himself as software engineer Chattawas Kongyut in Chiang Mai.
