Proof of obtaining goods when your supplier won’t issue an invoice

Say that you bought goods from your regular supplier (or even not so regular, but just this one time) and for some odd reason beyond you they’re not issuing an invoice for the purchase. The reasons may vary as human mind is surprising at times, so let them be. How would you however deal with the situation if you’re facing an audit? 

Let’s first get clear that there are various types of audits and for instance if it’s a tax audit, it may be wise to consult with your local tax advisor regarding the documents they’d require in this instance.

However, say it’s a financial audit and you’re asked to prove that you have the legal ownership of the goods. The documents that would hold meaning with regards ownership of the legal title for the goods would be any agreements you have with the supplier stating that such similar goods are delivered upon ordering to your premises. Regardless if such an agreement is in place, what you ought to have is a shipping document that states what, when and by whom was delivered and obviously this document should state that the recipient is you.

More or less whatever documentation you have with the name of the goods, with the name of the supplier and you, the better.
