Trustindex"I was spending 5-6 hours every month on invoicing and bookkeeping. Creating invoices in Word, copying bank transactions into spreadsheets, then panicking every January trying to figure out my tax. RentalBux changed everything. I create invoices in under a minute, expenses categorise themselves, and when quarterly MTD submissions are due, my figures are already calculated. I claimed £1,400 more in deductions last year because I actually tracked everything properly. Best of all, I've added those admin hours back to client work—that's £2,000+ in extra billable time."

Freelancing Should Mean Freedom.
Not Drowning in Admin.
You became a freelancer to do work you love, not to spend evenings wrestling with invoices and spreadsheets. But somehow admin keeps eating into billable hours. Invoices get sent late. Expenses go untracked. Tax time becomes a scramble through bank statements and faded receipts.
From April 2026, freelancers with qualifying income over £50,000 must also comply with Making Tax Digital—quarterly submissions to HMRC using approved software. That's four extra deadlines per year on top of everything else.
RentalBux is built specifically for freelancers who want professional systems without the complexity. Send invoices that get you paid faster. Track every expense automatically. Submit MTD returns in minutes. Spend your time on work that earns money.
From Client Work to HMRC Submission in Four Simple Steps
Streamline your freelance workflow from invoicing to MTD compliance. Everything you need to run your business and stay compliant—no accounting experience required.
Create branded invoices and send them directly to clients. Track payments and send reminders automatically. Allocate expenses to projects and see profitability in real-time. When quarterly deadlines approach, RentalBux handles the calculations and submits to HMRC with a few clicks.
Professional Tools Without the Enterprise Price Tag.
Every feature designed to save you time, get you paid faster and keep HMRC happy—without the complexity of accounting software built for accountants.
Professional Invoicing That Gets You Paid
Create branded invoices with your logo and payment terms. Send directly to clients by email. Track which invoices are paid, pending or overdue. Set up recurring invoices for retainer clients. Professional invoicing builds credibility—and gets you paid faster.
Project Profitability Tracking
Know exactly which clients and project types make you money. Allocate income and expenses to specific projects. See profit margins in real time. Make informed decisions about which work to pursue, which clients to prioritise and where to increase your rates. Stop guessing, start knowing.
Automatic Payment Reminders
Stop writing awkward payment chase emails. RentalBux sends automatic, professional reminders when invoices become overdue. Customise reminder timing and wording. Track who owes what and for how long. Reduce your average payment time without damaging client relationships.
Bank Feed Automation
Connect your business bank account, and transactions import automatically. RentalBux learns your spending patterns and categorises expenses intelligently—software subscriptions, travel, equipment, and client entertainment. Review and adjust if needed, but most transactions categorise correctly from day one.
Built for Freelancers Who Take Their Business Seriously.
Whether you work with one long-term client or juggle a dozen projects, RentalBux organises your freelance finances, so you always know exactly where you stand.
Creative Freelancers
Designers, writers, photographers and creative professionals who bill clients by project or retainer. Track invoice for completed work and allocate expenses like software subscriptions and equipment to the projects that use them.
Consultants and Coaches
Business consultants, executive coaches and professional advisers who charge hourly or day rates. Manage client relationships, send invoices for completed sessions and track which clients generate the most revenue with the least overhead.
Technical Freelancers
Developers, IT contractors and technical specialists who work on multiple short-term contracts. Track income by client, allocate project-specific expenses and maintain clear records for MTD submissions.
Marketing and PR Freelancers
Manage campaigns, content creation or communications for multiple clients. Track retainer income and project fees separately. Allocate ad spend, tool subscriptions and subcontractor costs to the right clients. See which relationships deliver profit versus just revenue.
Freelancers with Rental Income
Combine freelance work with rental property investment. Track both income streams in one platform—no need for separate subscriptions. Keep freelance and rental records properly separated for tax purposes while managing everything from a single dashboard.

Get Started FreeFAQ for Freelancers
Common questions about managing freelance income, client invoicing, and MTD compliance for self-employed creative and professional service providers.
What accounting software do most freelancers use?
Freelancers need software that handles professional invoicing, expense tracking and MTD compliance without unnecessary complexity. RentalBux is purpose-built for UK freelancers with all essential features included: invoice creation, payment tracking, project expense allocation, and quarterly MTD submissions.
Do freelancers need to register for Making Tax Digital?
Yes, if your freelance income exceeds £50,000 per year (or/and your total qualifying income including any rental property income exceeds this threshold), you must register for MTD from April 2026. RentalBux provides full MTD compliance with digital record keeping and quarterly submissions built in.
How do freelancers track expenses for tax purposes?
Use accounting software to record all business expenses with digital receipts attached. Common freelance expenses include equipment, software subscriptions, training, marketing, travel and use of home costs. RentalBux scans receipts automatically and categorises expenses following HMRC guidelines.
Can freelancers claim expenses against their income?
Yes. Any expense wholly and exclusively for your freelance business is tax-deductible. This includes equipment, software, office supplies, training, marketing, vehicle costs for business travel and a proportion of home costs if you work from home. RentalBux tracks everything and calculates your net profit after expenses.
