Purchase Reports
Purchase Reports turns your bills into buying intelligence: what each category costs you, how each vendor's prices are moving, and where cost adjustments have changed the picture after the fact.

Reading them well
- Start with Purchases by categories and compare it against your sales by category. Categories where you buy a large share and sell a small one are where working capital is sitting still.
- Use Vendor cost analysis before every negotiation. A supplier whose prices have risen three times this year while a competitor's held steady is a conversation you should be having with numbers in hand.
- Read the cost adjustments report as a process check. Frequent adjustments mean freight and customs are not being entered on bills when they arrive, so your margin figures are wrong between receipt and adjustment - see Add Surcharge.
- Compare the same period year on year, not month on month. Purchasing is lumpy by nature, and a quiet month often just follows a large delivery.
Tip: Vendor cost analysis is most valuable on the products you buy from more than one supplier. Landed cost, not invoice price, is the comparison that matters - which is why entering freight and customs on the bill is what makes this report honest.
Warning: These reports are only as complete as your bills. Purchases recorded as expenses or receipts instead of bills do not appear here, and goods bought without a bill do not appear at all.
Note: Cost figures reflect adjustments, so a report run today may differ from the same report run last month for the same period. That is correct behaviour - the cost genuinely changed - but note the run date when you circulate one.
