come with receipts

To (be ready to) produce evidence of something, especially that which disputes or disproves what someone has said or claimed. I sent Ali a bunch of emails about it, so if she says I never contacted her, I'll just come with receipts. A: "Boy, did his wife come with receipts posting those screenshots on social media." B: "Right? Guess he didn't think she'd seen his texts with his mistress!" When the boss accused me of never finishing and sending that report, I came with receipts real quick.
