The problem
Invoicing instalments on time remains a challenge
Instalment invoicing requires continuous oversight: which instalments have been sent, which are open, what percentage matches current progress, and does VAT reverse-charge apply? Often instalments come late — cashflow suffers.
Instalments sent late
Due to site pressure invoicing slips to the next week. That costs cashflow directly.
Determining progress percentages
Matching the correct percentage to actual progress requires project meetings and manual calculation.
VAT reverse-charge checks
Checking reverse-charge applicability for every instalment takes time, wrong codes lead to corrections.
No overview of outstanding instalments
Which instalments are sent, open, and how much cashflow is coming in? Often fragmented.
