Frequently Asked Questions about Sample Letter Requesting Ach Payment

When should I send an ACH payment request letter?

Send this letter immediately after an invoice is issued, a milestone is completed, or payment becomes overdue. Always send written confirmation even if you discussed payment verbally.

Do I need to attach my invoice with the request?

Yes, always attach the full matching invoice as a PDF. Accounting teams will almost always pause processing if supporting documentation is missing.

Is it safe to include bank details in this letter?

ACH routing and account numbers are safe to share for incoming payments only. Always send this request through a secure business email or portal.

How long does ACH payment take after request?

Most standard ACH transfers process within 1-3 business days after approval. Allow additional time for corporate accounting approval queues.

Can I send an ACH payment request via text?

You may send a short reminder via text, but always follow up with the formal written request via email. Formal requests create a paper trail for accounting.

What if the client ignores my payment request?

Send a polite follow up every 3 business days. After 14 days, call the accounts payable team directly to check for processing issues.

Should I include late fee terms in the request?

Only reference late fees if they were clearly agreed in your original contract. Mention them politely once payment becomes 7 days overdue.

Can I request same-day ACH payment?

You may request same-day processing, but note that most businesses charge an additional fee for this service. Always confirm fees in advance.

Who should I address the payment request to?

Address the request directly to the assigned accounts payable contact, not just the general company inbox. This cuts down processing time dramatically.
