Cash Flow Management: Survive Mission Gaps
As of 2026-08-16
A missed 15-day invoicing window or an unpriced 60-day payment term does more damage to a consulting practice than a bad rate negotiation — and neither can be fixed after the fact. This module sets the numbers that matter: a minimum cash buffer of 4 months of fixed costs plus the VAT float (roughly €35,000-€40,000 for a €150K/year practice), the invoicing discipline that removes 15+ days from the collection cycle, and the pipeline-timing rule — next mission confirmed 4-6 weeks before the current one ends — that keeps a normal 3-8 week inter-mission gap from becoming a forced dividend or a missed IS acompte. It also reframes the rate conversation: a client on 30-day terms is worth more than a higher day rate on 60-day terms once the cost of held receivables is priced in.
What you will learn
- Calculate the minimum cash buffer required for a French SAP consultant operating through an IS-regime SASU, accounting for fixed costs, VAT float, and corporate tax advance payment schedules
- Apply invoicing discipline — timing, payment terms selection, and active chase protocols — to reduce average collection cycles and prevent the most common self-inflicted cash flow delays
- Design a gap-management strategy that includes advance pipeline planning, a dedicated transition fund, and revenue-smoothing mechanisms such as milestone billing and retainer agreements
- Integrate fiscal timing events (IS acomptes, URSSAF regularisation, PAS adjustments) into annual cash flow planning so tax deadlines never coincide with empty receivables
The Consultant's Cash Flow Reality
Consulting cash flow is structurally lumpy in a way that employment income is not. A salaried employee receives 1/12th of their annual package on the 28th of every month regardless of project delivery. A consultant invoices at end-of-mission milestones or monthly, waits 30–60 days for payment, then faces a gap between missions during which they receive nothing while fixed costs continue. Understanding and managing this asymmetry is not optional — it is an operational competency that determines whether a consultant can sustain their practice over a multi-year horizon.
