FAQ
Do you work with Microsoft Dynamics 365 Business Central?
Yes — I use BC's OData APIs regularly for a production client. Sales orders, invoices, customers, custom entities — all supported.
Can you integrate ADP Workforce Now?
Yes. I've built time-tracking → ADP payroll sync in production. ADP's API is quirky; I know the gotchas.
My systems are old / weird / custom. Can you still integrate them?
Probably yes. If it has any API, database, file export, or even email output, I can work with it. Message me a description.
How do you handle authentication and security?
OAuth 2.0, API keys stored in secure vaults (AWS Secrets Manager, HashiCorp Vault), TLS everywhere. No credentials in code. I sign NDAs.
What if the integration breaks after delivery?
Standard includes 30 days of support. Premium includes 60 days. Ongoing maintenance is available as a monthly retainer.
I need something more complex than the Premium tier. Can you handle it?
Yes — my typical enterprise integration project is $8K–$25K. Message me for a custom offer.
