Most field service businesses do not have an invoicing problem, they have a gap problem: the days between a job being finished and an invoice going out. That gap is created on site, when the record of what was done is either captured properly or left to be reconstructed later, and it is closed by the schedule rather than by the accounting system.
The invoice is written by the work order
What was done, what parts went in, how long it took. If those are captured at the address the invoice is a formality; if they are not, somebody rings the technician on Thursday to ask about Monday. The quality of your invoicing is decided by the quality of your work orders, which is decided by how quick the app is in the van.
A ticket is not an invoice and should not pretend to be
A ticketing system tracks the request and its state; an invoice is a demand for money with tax consequences. Products that merge them make it hard to say which jobs are complete but unbilled, and that list is the single most valuable report a service business can look at on a Friday afternoon.
Complete but unbilled is the number to watch
On the worked example this site publishes, a job invoices $285 on average and the team completes 655 a month, which is $186,732. A week of unbilled completions is roughly $46,000 sitting still. Nothing about that is a billing system failure; it is a record that was never finished.
Keeping the paperwork
Records supporting what you charged are kept for tax purposes, which the Internal Revenue Service sets out for small businesses, and the practical version is the same in every trade: the invoice, the work order behind it and the estimate before it should be findable together, from the job, without anybody searching an inbox.
Questions people ask about field service invoicing software
Should invoicing live in the scheduling system?
The document should live with the job. Whether the ledger does is a separate question, and most businesses are better off keeping proper books where they already are.
How fast should an invoice follow the job?
Same day is achievable when the record is made on site. A week is normal and expensive, and the cost is entirely in the gap.
