Medium-sized business owners are in a vulnerable position in that they are growing but are still in need of help so that they don’t stagnate.
But these firms aren’t necessarily dealing with the accounting processes they once knew. HMRC is in the process of rolling out making tax digital (MTD), meaning that many business owners have had to change the way they do their accounting.
The problem is that a lot of accounting software providers gear their products towards small businesses, sole traders and/or freelancer. As the owner of medium sized business, that leaves it up to you to sift through the figures and cast your own judgements.
To help you decide, we’ve looked at the best UK mid-sized business accounting software packages on the market.
Best UK medium sized business accounting software
Every business is different. Most smaller businesses can make do with basic functions like invoicing, bank reconciliation, income and expense tracking and financial report generation. However, some slighter bigger businesses might need more.
Indeed, most UK small business accounting software offers the same features, it’s just that you may feel more comfortable with how one is designed over another – and then of course, there’s the cost.
Best accounting software for UK medium sized businesses
First, make a list of what you need to do in terms of bookkeeping and accounting.
- Do you need to track inventory and purchase ordering?
- Do you need to invoice payment deadlines?
- Do you need foreign currency transactions?
- Do foreign currency transactions convert to sterling?
- How many users will need to use the accounting software?
How much can you afford?
Although there are free options available, when it comes to UK business accounting software – and especially something as sensitive as financial information – it’s probably wise to pay for a package. Back in the 1970s, the US television industry coined the phrase, “If you’re not paying for the product, you are the product.” These days that means that the software provider sells on your data. Keep that in mind when doing your search.
The other change that has happened is the rise of monthly subscription as opposed to a one-off software licence. On the plus side, Software-as-a-Service (SaaS) means your tech is always up to date. The downside is that, as the months roll on, you eventually end up paying more than if you’d bought a one-off licence.
4 questions you need to ask your accounting software supplier
- How do you back up data?
- Tell me about customer support. What are your hours and how quickly should I expect a response if I raise an issue?
- Can you tell me about a similar client who’s signed up to your software?
- Does your platform support foreign currency payments and convert them into sterling?
Pick an accounting software solution that will grow with you
Don’t be tempted to buy the most basic licence only to find you’ve outgrown what’s provided within a year. Ask your would-be supplier to explain how its accounting software can scale with your growing business.
