Electrical and field service businesses quote jobs, buy materials, use subcontractors and invoice on completion or in stages. Good books show whether each job made money.
Quote, invoice, repeat
Send quotes and turn them into invoices. Use stage invoices for larger jobs and recurring invoices for maintenance contracts.
Job costing
Tag materials, subcontractors and income to a job using segments (Standard and above), then run profit and loss by job.
Materials and suppliers
Use purchase orders for larger orders and attach supplier invoices to bills. Trade counter receipts need to be kept. See receipt management.
Subcontractors and VAT
Construction work can involve the Construction Industry Scheme and the VAT Domestic Reverse Charge. These have specific rules, so confirm the treatment with your accountant and check the rates on each invoice.
Vehicles and tools
Record vans and expensive tools in the fixed asset register.
How AvrioBooks fits
Quotes, invoices, purchase orders, segments, fixed assets and VAT returns are included on suitable plans. For scheduling, dispatch and timesheets, use a field service tool.
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.
Frequently asked questions
Can I see profit per job?
Yes, with segments on the Standard plan and above.
Does AvrioBooks handle CIS or the reverse charge?
It lets you set tax rates, but confirm the correct treatment with your accountant.
Does it schedule engineers?
No. Use a field service tool for scheduling and bring the figures into your books.
