This is general information, not tax or legal advice. Check GOV.UK or ask an accountant about your own situation.
A small logistics company has high fixed costs and thin margins. Knowing your margin per customer, route or vehicle is the difference between growth and a cash crunch.
Track the big costs separately
- Fuel, tolls and parking.
- Driver pay, agency drivers and subcontractors.
- Vehicle finance, insurance, tax and maintenance.
- Depreciation of vehicles. See the fixed asset register.
Margin by customer or route
Tag income and costs with a segment per customer, route or vehicle and run profit and loss by segment.
Credit control
Customers often pay in 30 to 60 days while fuel and wages are due now. Run the ageing report weekly. See aged receivables, and bad debts for the worst cases.
VAT and fuel
Keep valid VAT invoices for fuel and costs you reclaim, and check the rules on any private use.
Cash flow
Forecast fuel, wages and finance payments against expected receipts. See cash flow forecasting software.
How AvrioBooks fits
Segments, the fixed asset register, ageing, cash flow forecasting and VAT returns are included on suitable plans. For routing, fleet tracking and payroll, use specialist tools.
What AvrioBooks does not do: it is accounting software, not a payroll, time-tracking or job-scheduling system, and it has no automatic bank feeds (it imports CSV, OFX, QFX and QIF statements). Use specialist tools for those jobs and bring the figures into your books.
