Sure - no problem at all :)
Out of interest - what are you using at the moment and why isn't your current solution doing what you want?
If you don't need extensive analysis but you're looking for a solid system, FreeAgent is a great shout https://www.freeagent.com/ which is super user-friendly and cheap.
Has built-in iXBRL functionality and you can submit accounts, corporation tax returns, VAT returns, run company payroll and submit your own Self Assessment tax return from within the software (after your accountant does a review of course ;))
If you guys are looking to scale up over the next year or two, getting the correct accounting & financial infrastructure in place sooner rather than later is really important and will save you a lot of time and cost when you'll eventually need to switch.
I would still recommend Xero though if you want the best infrastructure - if you're VAT registered with 5 employees I'm guessing your turnover is probably in the range of £250k so Xero would be ideal and can scale with you.
I just worry a bit as I've never heard of anyone using Odoo in UK, probably since it's primarily a US-based company.
