Missing costs are discovered after invoicing, reducing profitability and requiring awkward follow-up billing.

Job records remain open indefinitely because the closeout process is unclear or incomplete.

Final invoicing is delayed while chasing missing paperwork and supplier invoices across multiple systems.

What if the customer disputes the final invoice?

Having documented acceptance and detailed cost records in Zigaflow provides clear evidence of agreed work scope and actual costs incurred, making dispute resolution much simpler.

How do I handle variations that weren't in the original quote?

Capture variations in the job record as they occur, with customer approval where possible. Include these clearly itemized in your final invoice with supporting documentation.
