Got questions?

Can Crunch help me if I'm a plumber?

Yes. Whether you're a self-employed plumber taking on jobs yourself or running a larger plumbing business, Crunch can help you manage the financial side without adding more paperwork to your day. You can manage your accounts through our smart software and speak to certified accountants whenever you need them.

Do I need an accountant as a plumber?

Not necessarily, but a plumber accountant can take care of the bookkeeping, tax and financial admin that comes with running a plumbing business. A trade accountant can help with:

  • Tracking income and expenses from your plumbing jobs.
  • Identifying allowable business expenses, including tools, materials, equipment, fuel and vehicle costs.
  • Calculating your tax and helping you plan for your tax bill.
  • Preparing and filing your Self Assessment tax return.
  • Managing CIS if you work with subcontractors.
  • Understanding VAT and your VAT responsibilities.
  • Advising on the best structure for your plumbing business as it grows.
Can Crunch do my Self Assessment?

Of course. Our dedicated Self Assessment service means a certified accountant can prepare and file your tax return for you. Most of our accounting plans also include a Self Assessment tax return, giving you expert oversight to help avoid costly mistakes and make sure you don't miss available tax reliefs. You can also ask your accountant questions about expenses, your tax bill or Self Assessment deadlines.

Can I track my plumbing expenses with Crunch?

Absolutely. Record expenses through the Crunch app and snap photos of your receipts as you go, whether you've just bought materials for a job, filled up the van or picked up a new tool. Everything stays together, rather than leaving you with a pile of receipts to sort through later.

Can Crunch help me keep track of what I owe in tax?

Yes. By keeping your plumbing business income, expenses and allowable business costs up to date, it's easy to work out your profit and get a better idea of your Income Tax liability throughout the tax year. You can also speak to a certified accountant about your Self Assessment, tax bill, allowable expenses, CIS or how much you should set aside for HMRC.

Can I invoice customers through Crunch?

Of course. All our accounting options for plumbers, from software-only to full accounting support, include unlimited customisable invoices. Create professional invoices for your plumbing jobs, send them to customers and use automatic payment chasers for overdue invoices, so you can spend less time chasing payment.

What if I have a question about my plumbing business finances?

Of course. All our accounting options for plumbers, from software-only to full accounting support, include unlimited customisable invoices. Create professional invoices for your plumbing jobs, send them to customers and use automatic payment chasers for overdue invoices, so you can spend less time chasing payment.

What if I have a question about my plumbing business finances?

You can ask a Crunch accountant. You can speak to one of our certified accountants about the things that come up when you're running a plumbing business, from whether you can claim a particular expense to questions about CIS, VAT or tax. Our Sole Trader Pro and Limited accounting plans include unlimited access to experts.
