Sending an invoice is only the start of the cash-collection process. A contractor invoice tracker answers a more important question: what has actually been paid, what is still outstanding, and what is overdue?
Core fields to track
For each invoice, record the job or client, invoice number, invoice date, due date, invoice amount, payments received, outstanding balance and payment status.
A useful tracker should also calculate days overdue so old balances become visible without manually counting dates.
Invoice amount vs cash collected
Revenue and cash are not the same thing. If you invoice £8,000 and the customer pays £5,000, the tracker should show:
- Invoice amount: £8,000
- Cash received: £5,000
- Outstanding: £3,000
This sounds simple, but it becomes difficult to manage when several jobs, staged payments and change orders are active at the same time.
Use clear payment statuses
Keep statuses simple: Open, Part Paid, Paid and Overdue are usually enough for operational control. The status should reflect payment reality, not whether the work itself is complete.
Track due dates, not just invoice dates
The invoice date tells you when the bill was raised. The due date tells you when the cash should arrive. Both matter. A balance can be outstanding without yet being overdue.
Link invoices back to jobs and changes
If an invoice relates to a specific job or approved change order, record that link. This makes it easier to reconcile project profitability with cash collection later.
Review outstanding cash regularly
A weekly review of unpaid and overdue invoices can be enough for many small contractors. Sort by largest balance and oldest due date so attention goes to the items with the greatest cash impact.
Separate operational tracking from accounting advice
A spreadsheet can help you organise invoice and payment data, but your accounting and tax treatment should follow the requirements that apply to your business and jurisdiction.
Use one workflow from change order to collection
The Change Order & Payment Tracker combines approved extras with invoice and payment tracking, including outstanding and overdue balances. If you also need estimating and job-costing control, Contractor Profit OS keeps the wider commercial workflow together.
