What records should contractors and trades keep for accounting?

Contractors and trades should keep invoices, purchase receipts, materials records, mileage or vehicle evidence, subcontractor details, CIS deduction statements where relevant, VAT records if registered, bank statements and notes explaining mixed-use costs.

Can an accountant help with CIS and VAT together?

Yes. CIS and VAT often affect the same job records, invoices, subcontractor payments and cashflow. The safest route is to review the record system, VAT position, CIS evidence and payment timing together.

Is this page tax advice?

No. It is general guidance. Treatment depends on the business structure, contracts, records, ownership, VAT position and current HMRC rules, so personalised advice needs a proper review.

Accounting support for contractors and trades with moving parts to control.

Trades businesses often look simple from the outside, but the records can be messy: CIS statements, subcontractors, materials, mileage, tools, deposits, VAT timing and job-by-job cashflow. This route helps owners prepare the facts before tax, VAT or year-end pressure builds.

Contractor and trade accounting

The risk is not one receipt. It is losing the story behind each job.

When job costs, deposits, subcontractors and customer payments are not matched clearly, it becomes harder to explain profit, VAT, CIS deductions, tax set-aside and what the owner can safely take from the business.

This page is intentionally practical. It does not claim specialist sector proof Gardian has not approved yet; it gives contractors and trades a clean route into the right review.

CIS evidence

Deduction statements, subcontractor payments and contractor income need to be traceable before year end.

Materials and tools

Purchases need supplier evidence, job context and a clear split from personal spending.

VAT timing

VAT registration, returns and payment planning can change pricing, cashflow and bookkeeping routines.

Uneven cashflow

Deposits, retentions, slow payers and lumpy tax bills need more than an annual accounts conversation.

The record desk

What Gardian would need to review before recommending the route.

Business setupSole trader or limited company, VAT status, payroll status, CIS role and any subcontractor use.

Sales evidenceInvoices, deposits, staged payments, retentions, cash/card payments and unpaid customer balances.

Job costsMaterials, plant hire, tools, fuel, subcontractors, waste disposal, parking and other job-specific spend.

Vehicle and travelMileage logs, van costs, insurance, finance agreements and any private-use questions to review.

CIS recordsDeduction statements, subcontractor details, verification notes and monthly payment evidence where relevant.

Cash set-asideVAT, PAYE, CIS, Corporation Tax or Self Assessment money separated before deadlines become stressful.

Monthly workflow

A better accounting rhythm for trades businesses.

The goal is to stop records being reconstructed from van receipts, WhatsApp messages and bank memory at the deadline. A simple monthly routine gives the accountant cleaner evidence and gives the owner earlier warning.

Collect

Upload invoices, receipts, CIS statements, supplier bills and mileage notes while the job context is still fresh.

Match

Connect customer payments, deposits, materials, subcontractor costs and bank transactions to the right month or job.

Review

Check VAT, CIS, payroll, owner drawings, director loans or tax set-aside before the numbers are filed.

Decide

Use clearer profit and cashflow to decide pricing, hiring, equipment spend, dividends or when support needs to increase.

Contractor and trades FAQs

Questions to settle before the quote.

Do trades need specialist accounting software?

Software can help, but it is not the full answer. The important part is whether invoices, receipts, bank transactions, CIS evidence, VAT records and job notes are captured consistently enough for review.

What if my CIS or VAT records are already messy?

That is a common reason to ask for help. The first route may be clean-up and deadline triage before any longer-term tax planning or management reporting.

Can this work remotely?

Yes. Contractors and trades can use an online workflow for records, but human review still matters where costs, VAT, CIS, private use or owner drawings need judgement.

Preview review note: This page uses safe general guidance only. Before public launch, Gardian should confirm the sectors it actively serves, any approved proof examples, and exact professional-status wording.

Bring the records into one clear review.

If CIS, VAT, tools, subcontractors, vehicle costs or tax set-aside are creating friction, start with the fit check and route the enquiry properly.
