FAQ
Straight answers for finance and IT teams.
What is SYNCWAVE?
SYNCWAVE is integration middleware that connects supported ERP/accounting systems with Nigeria’s NRS e-invoicing environment—helping businesses transmit sales invoices, receive supplier invoices, and streamline related fiscalisation steps through one layer.
What does SYNCWAVE do with sales invoices?
It transfers supported invoice data from your business system into the NRS e-invoicing workflow and captures processing responses such as status and reference values where available.
Can SYNCWAVE receive supplier invoices?
Yes. Where the connector and business rules support it, SYNCWAVE can retrieve vendor invoices from the NRS portal and map them into the connected ERP for posting and reconciliation.
Which accounting systems are supported?
Reported integrations include QuickBooks Online, Desktop and Enterprise; Sage 200 Evolution, Sage 50 US and Sage 300 Cloud; and Odoo. Exact edition support and deployment prerequisites are confirmed during discovery.
Does SYNCWAVE guarantee compliance?
No software should be described as guaranteeing compliance. SYNCWAVE supports configured workflows; the taxpayer remains responsible for data accuracy and meeting NRS requirements.
How do I get started?
Submit a demo or enquiry with your ERP/accounting system details. Timing depends on edition, data quality and testing—estimates follow discovery.
