How does the onboarding process work for existing clients?
We assign a dedicated Onboarding Specialist to your firm. We migrate your clients’ data, validate their current nexus status, and configure their account. We do the heavy lifting to ensure the transition is seamless and requires minimal effort from your side.
Do you communicate directly with my clients?
That is entirely up to you. We can act as a white-labeled extension of your team where all communication goes through you, or we can work directly with your client’s finance team to handle operational details.
How much time will my team need to spend managing this?
Close to zero. We handle the setup, the monthly data ingestion, the filings, and the notices. Your role is simply to maintain the client relationship.
Who is liable if there is an error or a state notice?
We are. Zamp takes full responsibility for the accuracy of the filings we prepare.
My clients use different platforms (QuickBooks, NetSuite, Shopify). Can you support all of them?
Yes. We have native integrations with major ERP, billing and e-commerce platforms to ingest transaction data automatically. For clients with custom tech stacks, we can ingest data via API or simple CSV uploads, standardizing everything into one compliance workflow.
