Your sales and invoicing systems don't talk to each other?
Order Management, Sales and Invoicing for SMEs
GestFlow connects the complete cycle: quote → order → production → delivery → invoice. No more re-entry, no more forgotten invoices, no more invisible margins.
From quote to payment, a seamless cycle.
Disconnected systems
Sales in one file, purchasing in another, invoicing in a third. Each transaction is re-entered 2-3 times with risk of error.
Invoicing delays
Invoices go out days or weeks after delivery. Every day of delay = tied-up cash and cash flow pressure.
Invisible margins
How much does this client really bring in? Is this project profitable? Without an integrated sales-cost view, impossible to know.
Manual accounting sync
Exporting invoicing data to accounting takes time and generates errors. Double entry, discrepancies to reconcile.
How GestFlow solves this problem
Integrated sales-purchasing-invoicing cycle with real-time margin tracking and automatic accounting sync.
Manage the complete client cycle: quotes, orders, deliveries, invoices — all connected
Supplier orders linked to projects and production orders — complete traceability
Visualize profitability per client, project and product in real time — revenue vs costs
Automatically sync with your accounting software — zero double entry
