Bill subcontractors with legal certainty – via credit note.
For general contractors who work with subcontractors: no more incorrect invoices, missing documents and WhatsApp chaos. Mendato flips billing around – you issue the credit note yourself, GoBD-compliant and audit-proof.
Working with subcontractors
is a risk – but it doesn't have to be.
Customs and the tax office are scrutinising subcontractor relationships ever more closely. Three things go wrong most often.
Incorrect invoices
The subcontractor invoices incorrectly, incompletely, too late – not GoBD-compliant. You chase after it and correct in endless loops.
Missing documents
Public liability insurance, certificates – if a document is missing during an audit, it quickly becomes a liability risk.
Communication chaos
Assigning jobs via WhatsApp and phone – and losing track of which subcontractor is working where.
You no longer wait for the invoice.
You write the credit note.
The biggest problem in the subcontractor business is billing. Mendato flips it around – and makes it audit-proof.
The invoice from the subcontractor
In practice, the subcontractor sends the general contractor an invoice. Something constantly goes wrong – and in the end you carry the risk.
- ✕Mandatory details missing, not GoBD-compliant.
- ✕Wrong amount, arrives too late – you chase after it.
- ✕Correction loops – and the tax office may not even recognise it.
The credit note from the general contractor
Mendato turns the tables: you create a credit note to the subcontractor yourself and transfer the amount. You no longer have to request anything or wait for anything.
- ✓GoBD-compliant with all mandatory details – automatically correct.
- ✓Correct amount based on the work actually performed.
- ✓No waiting, no correction loops – you stay in control.
- ✓Audit-proof for the tax office and customs.
All documents neatly in the digital subcontractor folder.
You need important documents from every subcontractor – public liability insurance, clearance certificates and more. If something is missing during an audit, it becomes a liability risk. The digital folder keeps everything complete and ready to present.
- ✓All documents in one place – neatly uploaded and stored.
- ✓Completeness at a glance – what's there, what's still missing?
- ✓During an audit, everything is immediately ready to present – no risk.
Subcontractors in the roster – no more WhatsApp.
Instead of assigning jobs by WhatsApp and phone, you schedule subcontractors directly in the roster. You see where each sub is working – and the subcontractor sees all their jobs in their own access.
Invoices & WhatsApp are a risk.
Mendato makes it safe.
