Client number followed by invoice number Mar 24, 2023

I assign a number to each client and then my invoice number is the client number followed by the invoice number (e.g. client No. 5 and invoice No. 10 for this client will be 5.10).

- Date (6 digits)

- Year code (2 digits)
- Consecutive number (3 digits)

Local tax laws require me to have consecutive numbers for invoices, but the numbers can start at any number on 1 January (and may not overlap with any numbers of previous years), so I just increment the year code by 1 each January and reset the last three numbers as 001.

If a client wants me to type in the invoice number, and it doesn't allow all the characters, I just enter the last 5 digits.

The date code relates to the date of the deadline of the job. For invoices spanning multiple jobs, I may use a date code like 230100, etc.

Doesn't matter Mar 24, 2023

As long as your invoice # is unique, the client doesn't care about its format at all. You can use 1 digit or 10 digits.

In alphabetical and numerical order.
For example, my first invoice of this year would be something like A-0001-K23 (K23 = 2023).
When I get to the end of the alphabet, I start again like this: 2A-0027-K23, 2B-0028_K23... and so on.
This way, it is easier for me to find them when necessary.

Year + invoice number Mar 24, 2023

The number format of my invoices is year followed by the sequential position of the invoice. Invoices are filed by year + invoice number + client name.

Client initials + date, + letter to specify estimate or invoice + number because I do still have clients who ask for more than one translation in a month without adding them all up

SC0323-F01

I used to do F0323-SC01 but changed this year so that everything would be listed in numerical order and the estimate would also be right next to the corresponding invoice.

payment institution name PLUS sequential numbers (plus a, b, c if there was a problem or an extra) Mar 25, 2023

Adding the payment institution name e.g. PayPal, XXX Bank, allows me to quickly see which account the payment went into.

Tax authorities Mar 25, 2023

Here in the UK, the tax authorities are flexible in relation to this criterion, so so long as the numbering system is credible.

In my case, I use a system based on each client and the calendar year in which the invoice is issued.

This means that each invoice has a unique sequential identifier. For example:

Invoice Pallino 02/2023
Invoice Pallino 03/2023
Invoice Caio 11/2023
Invoice Caio 01/2024

and so on.

1,2,3 but I start anew for each client each year. After trying an uninterrupted sequential method, I found individual annual records more convenient. Quicken not only doesn't mind duplicate numbers after a polite clarifying question, but helps to single out full list of invoices for each client without keeping separate invoice folders on the c: drive.

Year/Country/Sequential Number Mar 25, 2023

For example:
2023/UK/001, 2023/DE/002, 2023/ES/003, 2023/UK/004...

For file names I use the format: 2023 001 UK Client name, 2023 002 DE Client name, 2023 003 ES Client name...

Tax authorities require consecutive invoice numbering.

Client Name followed by year, then number (for that client).

Suárez2023.3 means that this is my third job this year for Suárez.
