Invoice numbering

[cojak]

Never yet had a satisfactory answer to this one. Personally I treat the agency invoice as a remittance advice - which it is, functionally - and raise my own correctly numbered invoice in parallel. The self-billing rules (which weren't written for continual supply of services, only widgets, but hey...) say you don't submit invoices, it doesn't say you can't use your own tracking mechanism.

This what I do and attach the self-billed invoice to my invoice (which I don't send out). Both are then reconciled.

I use a unique sequence for each client that I bill, and just enter the invoice number from self-billing if I use that. It may be an issue if another self-billing system clashes with one I've already used, but I'll deal with that if it ever happens.

I started at 1 and now I'm at 50. I'm not confused.

I have to wonder if any of you guys have ever worked for a proper company or used a computer based financial system. I have never experienced anyone having suffixes or prefixes to denote client.

Your first invoice is 00001, then comes 00002. Its really easy.

Look at your phone bill: BT uses AA 9999 9999 A999 - the first 10 are your account number, the next letter is the type of bill (Q for Quarterly, M for Monthly, etc) and then the last 3 are sequential from your previous bill, starting with I001 (I for Initial). Vodafone uses your account number followed by .000001 continuing sequentially. These are but two examples.

For a smaller concern, you absolutely don't want clients knowing you're issuing only a few invoices, for a large concern, it's the same issue but for the opposite reason!

My accountant says not.

They recomended keeping all issued invoices as is, but then for each client switch to a sequential number for the next invoice.

Apparantly (accoring to my accountant) this rule exists so that if you get investigated, they can tell at a glance if any invoices have gone missing...

DO NOT renumber them, but you could start a new sequence to continue as you mean to go on. Any query can be easily calmed with a simple explanation of the problem you anticipated and how your new system will avoid it. (This MUST be a RARE occurrence - more than once or twice ever is likely to cause further investigation!)

Start with 000001 and go to 000002 and so on.

On the file name I put the initials of the client, but not on the actual invoice number, but then I just use an excel spreadsheet invoice format, so I can keep things simple.

Strictly speaking the supplier (you) raises invoices and what you get from the purchaser is a purchase order, and it makes sense to put the PO number on your invoice. It doesn't matter that the agency doesn't require you to submit the invoices month to month, but you could submit the invoices in the event of a dispute. Never done self billing, but if I did that's how I'd treat it.

I just started from 1 and counted up.

Take off your tin foil cap and stop resurrecting zombie threads.

When you're on the bench like I am, invoice numbering is the least of your concerns!

I number my invoices with a GUID
