Not every business needs ongoing monthly bookkeeping. Some businesses have irregular income, seasonal businesses have quiet periods, project-based businesses only need bookkeeping for specific projects, and some businesses just need occasional help with catch-up work or one-off tasks. Ad-hoc bookkeeping gives you flexible support when you need it, without committing to ongoing monthly services.
Here's what you need to know:
- Ad-hoc bookkeeping helps businesses that don't need ongoing monthly bookkeeping but need help with specific projects or catch-up work—pay for what you need, when you need it
- Project-based bookkeeping tracks income and expenses for specific projects, helping businesses understand project profitability and make better decisions about which projects to take on
- Flexible bookkeeping services suit businesses with irregular income, seasonal businesses, or businesses needing occasional help—perfect for businesses that don't fit the monthly bookkeeping model
- Ad-hoc bookkeeping can be more cost-effective than ongoing monthly services for businesses with low transaction volumes or irregular activity—no monthly fees when you don't need ongoing support
The problem is most bookkeeping services only offer ongoing monthly packages. That works great if you have regular transactions every month, but if your income is irregular, if you're a seasonal business, or if you only need occasional help, you're paying for services you don't need. Ad-hoc bookkeeping solves that.
We handle project-based and ad-hoc bookkeeping for businesses that need flexible support: project-based bookkeeping, ad-hoc catch-up work, one-off bookkeeping tasks, and flexible support. Whether you're a project-based business in Medway needing project profitability tracking, a seasonal business in Maidstone needing occasional help, or a business in Canterbury needing catch-up work, we'll provide bookkeeping support that fits your needs. No monthly commitments, no paying for services you don't need—just flexible bookkeeping when you need it.
What this helps you do (fast)
- Pay only for what you need — No monthly fees when you don't need ongoing support. Pay for bookkeeping only when you have work to do or projects to track.
- Track project profitability — Project-based bookkeeping tracks income and expenses for specific projects, so you can see which projects are profitable and which aren't. Make better decisions about which projects to take on.
- Get flexible support — Bookkeeping when you need it, not when you don't. Perfect for seasonal businesses, irregular income, or businesses needing occasional help.
- Handle catch-up work — Need to catch up on bookkeeping after a busy period or when you've fallen behind? Ad-hoc bookkeeping handles catch-up work without requiring ongoing monthly commitment.
- One-off tasks — Need help with a specific task (bank reconciliation, VAT return, year-end preparation)? Ad-hoc bookkeeping handles one-off tasks without ongoing commitment.
- Save money on low-volume businesses — If you have low transaction volumes or irregular activity, ad-hoc bookkeeping is more cost-effective than ongoing monthly services.
How it works
Step-by-step process for project-based and ad-hoc bookkeeping:
- Discovery call — We chat about your needs: what type of bookkeeping help you need (project tracking, catch-up work, one-off tasks), how often you need support (occasionally, for specific projects, seasonally), what your business activity looks like (regular, irregular, seasonal), and what your budget is.
- Scope definition — We define exactly what you need:
- Project-based bookkeeping: Specific projects to track, project duration, what expenses/income to track per project
- Ad-hoc catch-up work: Period to catch up on, what needs doing (transactions, reconciliation, VAT returns)
- One-off tasks: Specific task needed (bank reconciliation, VAT return, year-end prep, etc.)
- Flexible ongoing: How often you're likely to need support, what triggers bookkeeping work (project completion, busy periods, etc.)
- Bookkeeping delivery — We do the work:
- Project-based: Track income and expenses for specific projects, provide project profitability reports, help with project invoicing and expenses
- Ad-hoc catch-up: Catch up on missed bookkeeping, reconcile accounts, prepare VAT returns, organize records
- One-off tasks: Complete specific tasks (bank reconciliation, VAT return preparation, year-end accounts prep, etc.)
- Flexible ongoing: Support when you need it (during busy periods, for specific projects, when you need help)
- Reporting and handover — We provide reports and handover:
- Project reports: Project profitability, income/expense breakdown, project completion status
- Catch-up reports: Summary of work completed, updated account balances, compliance status
- Task completion: Completed tasks with documentation and explanations
- Flexible ongoing: Regular updates when we do work, summaries of what's been done
- Ongoing flexibility — We remain flexible for future needs:
- Project support: Available for new projects as they come up
- Ad-hoc support: Available for catch-up work or one-off tasks when needed
- Flexible ongoing: Available on an as-needed basis without monthly commitment
What project-based and ad-hoc bookkeeping includes:
- Project-based bookkeeping (project income/expense tracking, project profitability reporting)
- Ad-hoc catch-up work (period catch-up, reconciliation, VAT returns)
- One-off bookkeeping tasks (bank reconciliation, VAT return prep, year-end prep)
- Flexible ongoing support (as-needed basis, no monthly commitment)
- Reporting and handover (project reports, catch-up summaries, task completion docs)
Common ad-hoc bookkeeping scenarios:
- Project-based businesses: Construction projects, consulting projects, event projects needing project profitability tracking
- Seasonal businesses: Seasonal businesses needing bookkeeping during busy periods, quiet during off-season
- Irregular income businesses: Businesses with irregular income needing occasional bookkeeping support
- Catch-up work: Businesses needing to catch up on bookkeeping after busy periods or when falling behind
- One-off tasks: Businesses needing help with specific tasks (bank reconciliation, VAT return, year-end prep) without ongoing commitment
We work with whatever bookkeeping system you're using—Xero, QuickBooks, Sage, spreadsheets, or starting from scratch. The key is providing flexible support that fits your business needs, not forcing you into ongoing monthly services you don't need.

Costs & timelines
Pricing factors:
- Type of work — Project-based tracking costs less than comprehensive catch-up work
- Volume of work — More transactions, more projects, more catch-up work means more cost
- Complexity — Simple tasks (bank reconciliation) cost less than complex work (comprehensive catch-up, year-end prep)
- Urgency — Rush work may cost more due to prioritization
Commonly reported ranges by local providers:
- Project-based bookkeeping: £200–£500 per project depending on project duration, transaction volume, and reporting needs
- Ad-hoc catch-up work: £300–£800 depending on period to catch up, transaction volume, and complexity
- One-off tasks: £150–£400 per task depending on task complexity (bank reconciliation £150–£250, VAT return £200–£350, year-end prep £300–£600)
- Flexible ongoing (hourly): £40–£60/hour for ad-hoc support when needed
Why ad-hoc bookkeeping can be cost-effective:
- Pay only for what you need (no monthly fees when you don't need support)
- Suitable for low transaction volumes (more cost-effective than monthly packages)
- Perfect for irregular activity (don't pay for months with no activity)
- Flexible pricing based on actual work needed
Timeline: Depends on the work needed. Simple one-off tasks (bank reconciliation) might take 1–2 days. Project-based bookkeeping depends on project duration. Catch-up work might take 1–2 weeks depending on period and complexity. We'll give you a timeline when we quote.
No monthly commitments. All ad-hoc work is quoted and paid for per job. Flexible ongoing support is available on an as-needed basis without monthly commitments.
