With reference to your invoice no. 21026 of 3 July, we have to point out that you have made an error in your total. We calculate the correct figure at £237.73, not £247.73 as given by you.
Our cheque for my former amount is enclosed and we should be obliged if you would amend the invoice or pass the necessary credit.
 Error in extending item on invoice
We thank you for prompt delivery of our order no. 212 of 3 May, and are pleased to report that the goods arrived in good condition.
Your invoice has now been received, and on checking this we find that you have made a mistake in the extension of item no. 3,15 chairs at £3.35. You rave extended this as £53.60, whereas the correct figure is £50.25. Please let us have your credit note for the difference
 Disagreement on goods sent and charged
Our indent no. 00265, your invoice no. 2345
The various items supplied against the above indent have now teen checked and we regret to inform you that there is a discrepancy' between the goods sent and the amount invoiced.
Item no. 5 of our indent called for 10 x 6 men's poplin shirts, size L. and this quantity was in fact received. We noticed that your packing note showed 12 x 6 shirts against this item, and now we find that your invoice shows this quantity, too. Will you kindly look into the matter and let us have your credit for the difference in due course.
 Incorrect discount in statement
Your statement of account for the December quarter has been found in order but we think you have made an error in the special discount shown. In your letter of 15 September last you agreed to allow us 5% extra on quarterly transactions exceeding £1,000 in value. The amount of the statement in question is £1,106, but you have shown discount at only 2,5%.
Will you kindly adjust this, after which we shall be pleased to pass the account for payment.
 Discrepancies in statement
We have received your statement for December 1978 and must point out certain discrepancies in your entries:
(1) 5 Dec. You debit us £55.38 against invoice no. 31752, but we have no record of such an invoice in our files, nor can we trace any packing note for goods that might explain this item.
(2) 19 Dec. Invoice no. 32101 for £31.50. This item is charged twice; as you will see, you have made a similar debit dated 29 December.
(3) Your final entry is 53p carnage added to your entry for invoice no. 33711. We take it that this charge is made because the order in question is under £10 in value. While agreeing that you are entitled to make this charge, we think that the volume of business done with you in December should warrant a free delivery in this case.
Will you please let us have your comments.
 Customer queries credits
Your quarterly statement arrived a few days ago and shows a balance in your favour of £527.40.
We have to draw your attention to two credit items which you do not show on this statement: firstly, an amount of £1.89 due to us in accordance with your credit note A124 of 17 May, and secondly, an amount of £5.83 due to us for empty crates and carboys returned to you on 30 April.
We have never had any credit note for the second of these two items, although we wrote to you on 5 June asking for credit.
Under these circumstances we are deducting a total of £7.72 from the amount of your statement and are instructing our bank to remit the sum of £519.64 in full settlement.
Seller complains of short payment
We thank you for your remittance for £117.18 received today by our bank. Our official receipt is enclosed.
The amount of the statement in question is £157.18 and as you make no mention of this in your recent letters we are wondering if this is a clerical error* on your part. Perhaps you would remit the balance of £40 in the course of the next few days.
 Seller rejects request for discount
We thank you for your letter of... in which you draw our attention to an apparent error in the discount we have calculated on your quarterly statement dated 31 December. Through an oversight, no accompanying letter went out with your statement. The position is that the discount of 5% agreed on orders over £1,000 was granted on condition that no balance was outstanding from previous accounts. At the time of writing there is a balance of £300 due from our last account rendered, and under the circumstances we can only offer the normal 2,5 % discount.
You will appreciate that while we are anxious to give every assistance, we are only able to make discount concessions if accounts are cleared promptly.
