Being a small business owner life runs at a 100mph. My absolute dread has always been my self assessment. A couple of years ago I took the decision to use the services of an accountant. Several phone calls later they were all ‘too busy’. I found Lucy’s number and nothing was too much trouble. Friendly and so accommodating and never too busy to answer questions. A gem of a find.”

Online Accounting Questions, Answered
Thinking about going digital with your accounts? These FAQs cover everything from online support to using software like Xero or QuickBooks.
Yes—online accountants are just as good (if not better) than traditional ones. With secure software and expert support just a message or call away, you get everything you need without office visits. At Simplex, we work with small businesses virtually across the UK, offering practical support, real-time bookkeeping, and stress-free tax help. It’s flexible, personal, and built around you—so you can focus on your business, not your paperwork.
UK accountants often charge £50–£150 per hour depending on the work. But for small businesses, fixed-fee packages are usually more practical. At Simplex, we offer monthly support from just £25, with no hidden charges. You get help when you need it, without worrying about rising costs. It’s a straightforward way to stay on top of your finances—so you can spend less time stressing and more time growing your business.
Absolutely. Online accountants handle everything remotely—bookkeeping, tax returns, payroll, and more. At Simplex, we use secure cloud software and messaging tools to support UK business owners wherever they are. You still get the same level of service, just without the in-person meetings. It’s faster, easier, and fits your schedule. Whether you’re just starting out or scaling up, online accounting is a smart and flexible choice.
QuickBooks is brilliant for keeping your records tidy, but it won’t replace an accountant’s ongoing support. It tracks income and expenses, but it won’t help you stay compliant or understand what the numbers really mean. At Simplex, we use QuickBooks alongside our services—giving you clarity, accurate reporting, and help when you need it. Think of QuickBooks as the tool, and we’re here to help you get the most out of it.
As soon as you’re earning regularly from self-employment, running a limited company, or handling VAT—it’s worth having an accountant. At Simplex, we help you stay compliant, get organised, and free up your time. Even if you’re just getting started, our monthly packages give you the right support from day one. The sooner you get things set up properly, the easier it is to avoid stress and grow smoothly.
Most UK accountants charge between £150–£300 for a basic tax return. More complex returns—like for landlords or company directors—can cost more. At Simplex, we include your tax return as part of a monthly package starting from just £25 per month. That means no big one-off bills and year-round support when you need it. It’s a smarter way to manage your taxes and stay in control all year round.
Xero is a brilliant tool—but it works best with support from an accountant. At Simplex, we’re Xero-certified and help clients make sure everything’s accurate, deadlines are met, and their records are in great shape. Software is helpful, but it can’t replace the reassurance of having someone to turn to with questions. With the right setup, you get the best of both: powerful tools and reliable support behind the scenes.
