Compare · Building it on Sage Intacct Platform Services
You could build this. Here is what that actually takes.
Platform Services is genuinely capable, and a custom object with an approval workflow is a reasonable weekend for a good consultant.
External supplier identity is not.
The hard part is not the screens. It is guaranteeing that a supplier can never see another supplier's orders, handling passwordless access and revocation, storing tax and banking data safely, keeping documents private, versioning compliance records, and maintaining all of it as your supplier base grows.
Honest framing
- Build it if you have three suppliers and a strong internal developer.
- Buy it if a mistake in supplier isolation would be a serious problem for your company.

Every supplier request is scoped to your company and their vendor record. A query without that scope fails rather than returning data.
