A trip is the unit, not a bottle
Faisalabad mills, Multan schemes, Quetta compounds, and Karachi sites all buy water by the load. Record tanker size, site, and amount per trip. Partial loads and two trips in one day must stay as two lines or month-end billing becomes a fight.
Credit is the default for sites
Construction and factories rarely pay cash on the running board. Give each site a running balance and a limit. Check outstanding before the next dispatch. Payment In is how a bank transfer drops the balance without a fake trip.
Do not mix the household 19L rider
If you also sell bottles, keep tanker zones and vehicles separate. A mill on the edge of Faisalabad will wreck a Madina Town bottle round. One ledger is good; one mixed list is not.
Waiting time is a cost you can name
Time at the site is time the tanker is not earning. Build a free window into the rate and charge beyond it, especially on busy Karachi and Lahore days. Software will not invent the policy, but it will show which sites eat the clock.
FAQ
- Which Pakistani cities need tanker software most?
- Any city with construction, mills, or scarce piped water: Faisalabad, Multan, Quetta, and large Karachi sites are typical. The software job is trips, credit, and vehicle tracking.
- Can I run tankers and 19L bottles in one Mashqi branch?
- Yes. Use different items and zones. Both post to the same customer ledger and reports.
