I’m trying to create an estimate to keep track of interest to be charged on an overdue invoice. However, one of the calculated interest is to 3 decimal places, but the unit cost is limited to only 2.
I’m aware quantity has been suggested to be made decimal, but can’t find any in relation to unit cost.
So, can I suggest that this is a possibility please? 
I’m afraid it’s one of those things that we just won’t be able to easily change now, it would require a massive overhaul. The risk of introducing errors would be so great that we’d have to perform 100s of tests that would take weeks.
As amounts ultimately need to be rounded down to two places, is it an option for you to detail specific interest rates in the description?
No problem at all, just thought I’d ask the question!
I’ve found a small solution of just using the rounded values (for ease of calculation) and having a new line for rounding correction.
Thanks for getting back to me though - appreciate it.
Love the changes to the PO procedure but wondered if it was possible to amend the unit cost field to allow for 4 decimal places (e.g. £0.0325)? A lot of components we buy are priced in fractions of a penny.
Hi @manleyc
I’ve converted this topic to a feature request for the moment. If there’s enough interest, then we’ll take a closer look to see if this is feasible.
Hi,
how do i change this on PO, i need at least 3 decimal places.
Hi @delan
With the the quantity, you can enter up to 4 decimal places
How about the price, i need 4 dec. places too.
This I’m afraid is not currently supported, although you’ve posted on the right topic. This is feature is not planned, however we will continue to monitor interest.
Hi, I cannot amend the unit price of the item on a sales invoice, to 4 digit decimal. The price of the item I am selling is GBP0.0188 per unit, but it appears as 0.02 on the invoice when I type it. I will need the decimals to be 4?
Hi @dtex,
This is not supported currently. I have moved your post onto the feature request thread.
Thanks,
Beth
QuickFile doesn’t allow fractions of a penny for the unit cost but it does allow fractional quantities, so a possible workaround might be to have the “unit” be 100 items at a price of £1.88 and then if you want to sell, say, 20 items then set the quantity to 0.2.
Hi, we’re also looking to be able to use 4 decimal places in the unit column when invoicing our customers for energy on our caravan site. The unit price currently is 0.1242 but obviously rounds down to 0.12 currently. We would appreciate the ability to invoice to this level of accuracy.
Thanks,
You can add your vote at the top of the thread as this a feature request thread.

Hi Glenn
back in 2014 you wrote:

in response to a question about unit prices to 4 decimal places.
Would this still be the case? If it is would you be able to expand on the resons why introducing the ability to have unit prices to four decimal places would introduce errors and result in an impossible amount of checking?
Thank you.

Hello @3Unique
We monitor feature requests for community interest to invest time in developing for our customers.
As it stands this request only has 7 votes.
The unit price affects all areas of the software requiring a significant investment in time and resources to implement.
While this may seem disappointing, never say never, as we work through continuous improvements in the platform and the introduction of new features it may be introduced in the future.
Thank you Steve and understood and though disappointing not a biggie. That said it is a surprise it wasn’t built in at the start.
Maybe one day you will be able to get AI to do all that testing for you in a blink of an eye? 
Regards
Michael
