Before a payment leaves your account, a small number of confirmations make the difference between an order you can hold someone to and an order you can only describe. None of them require technical knowledge.
The four confirmations
- Who is selling. The contracting entity, named on the invoice.
- Who is receiving payment. The beneficiary, which should be explainable if different.
- What is being bought. SKU, specification, quantity unit and pack contents.
- What happens if it is wrong. The remedy, stated in writing.
Why the quantity unit is easy to get wrong
Trays, boxes and individual fans are three different units, and a quotation that says a number without the unit can be read more than one way. A threefold difference in quantity is entirely possible between readings of the same figure.
Confirm the unit and, if trays, the fans per tray. Two numbers that together define the quantity.
Why the remedy belongs on the invoice
A remedy agreed after a problem appears is negotiated under pressure. The same remedy, stated before payment, is a term both sides accepted when there was nothing to argue about.
Correction, replacement or credit are the usual options. What matters is that one is named and the conditions are clear.
Keeping the record
Store the invoice, the approved sample photographs and the specification together. When a tray arrives that looks different, those three documents are the entire conversation, and the disagreement usually resolves in one exchange rather than several.
This is also why a written specification per SKU earns its effort. It is the only document that lets a low-value order be assessed without either side relying on memory.
These are not precautions against a specific supplier. They are the minimum record that makes any supplier relationship work, because they define what both sides mean by the product.
