This prints one bill. A lab prints a hundred a day.
Every bill here starts from an empty form. In the product the patient is already on file, the rate list fills the lines, the bill number comes off a counter that never repeats, and what was billed shows up in the day's collection figure.
ZapLab is paid software, not a free plan: from ₹349 a month billed yearly, plus GST. The trial runs 30 days without a card, and a first term is refundable for 30 days.

This is a standalone utility, not a laboratory information system. It does not keep a patient record, number your bills, track a sample, or store anything between visits. If you want those, read what is actually free for an Indian lab before you pay anyone, including us.
