Build the software your company actually needs. Run it on operations that already work.
VendorSpoke is a complete application, and most customers never want anything else. But if your team is going to build its own interfaces and assistants — and increasingly it can — we would rather that sit on top of us than beside us.
The expensive part was never the screen.
Put a competent developer and a good model together and you will have a working dashboard by Friday. What you will not have is the rest of it: a vendor who is qualified for this trade at this address today but not next month when the certificate lapses; an award that has to be blocked because of it; a commitment that routes to the person allowed to approve that number, lands against the right property and contract, and can still be explained when the owner asks about it two quarters later.
None of that is interesting to build, and all of it is unforgiving. It touches money, permissions, compliance and history at once, and the moment you write it yourself you are maintaining it forever — including the parts you only discover after the first disputed invoice.
So split the work along the line that actually matters. What is specific to your company is worth building and rebuilding as often as you like. What every operator in this industry needs — the vendor network, the bidding, the commitments, the approvals, the billing and the record of all of it — is worth renting from something that already does it.
Building on it
The whole product runs on a typed interface over the data described above, and the assistant inside the app uses it under the same permissions a person has — a cost-blind role stays cost-blind when it asks a question rather than clicks a screen.
Customer-built tools use that same interface. Access is scoped to your workspace and to the permissions of the user it acts for, so a reporting tool cannot see more than the person who set it up. Tell us what you intend to build and we will point you at the right entry points and the integration patterns other customers use.
