Understanding your pharmacy profits with a digital ledger

Most pharmacy owners know today's revenue. Few know today's margin. Revenue is what the counter rings up. Margin is what stays after you paid for the stock you sold.

DoseBook posts every sale and purchase to an append-only ledger with six account types: Cash, Inventory, Revenue, Payable, Discount, and Tax. Entries are never edited — only new correcting entries are added.

When a sell invoice posts, the ledger records cash in and revenue out automatically. When a purchase posts, inventory increases and payables increase. Adjustments create their own correction entries without touching the original.

The dashboard shows revenue and gross margin percentage with period-over-period trends. Item history goes deeper — per-medicine revenue, purchase cost, and price trend charts over 24 months.

Understanding your pharmacy profits is not about more data. It is about the right data, recorded automatically, that nobody can quietly change after the fact.
