Every effective missing invoice request includes these core details:

• Official purchase order number
• Exact delivery or work completion date
• Approximate order value (if known)
• Your direct accounts payable contact details

Frequently Asked Questions about Sample Letter Request Missing Invoice

How soon should I send a missing invoice request?

Send your first request 3 business days after confirmed delivery or work completion. This gives the vendor time to process paperwork without being pushy. Follow up every 3 business days for high priority items.

Should I call or email for a missing invoice?

Always send a written request first. This creates a paper trail for accounting and audits. Only follow up with a phone call if you have not received a response after two written requests.

Can I charge late fees if a vendor does not send an invoice?

You cannot charge vendors for late invoice submission unless this is explicitly stated in your original contract. Always communicate deadlines clearly in your request instead.

What if the vendor says they already sent the invoice?

Politely ask them to resend it to a confirmed alternate email address. Also request they send it as an attachment rather than embedded in the email body to avoid spam filters.

How do I request an invoice without sounding rude?

Start by confirming receipt of their goods or work first. State clearly that you are ready to process payment immediately once you receive the document. Avoid accusatory language at all times.

What details do I always include?

Always include the purchase order number, delivery date, and order description. Add your contact information and confirm the correct email address they should send the invoice to.

Can I use these templates for personal purchases?

Yes, these templates work for personal purchases too. Simply remove company titles and adjust the tone to match informal or personal vendor relationships.

What do I do if the invoice is permanently lost?

Ask the vendor to issue a duplicate invoice marked clearly as a copy. Most accounting systems accept duplicate invoices as long as they are marked correctly and include all original details.

Missing invoices don’t have to derail your accounting schedule. With the right sample letter, you can get the documents you need while maintaining good working relationships with your vendors. Always double check reference numbers before hitting send.

Save these templates to your shared accounts payable folder today. Test one with your next missing invoice follow up, and adjust the tone to match your business voice. You’ll spend less time chasing paperwork and more time running your business.
