Frequently asked questions

What is Internal Tools Development?

Internal Tools Development is a more specific Custom Software Development buying path. Use it when the broad service category is too general and you need vendors with visible proof around this exact build type.

Should I start from this hub or a city folder?

Start from this hub to understand scope, proposal checks, and related folders. Open a city folder when you want ranked vendor cards for a specific market.

Why are some city folders still marked in verification?

Vendar keeps the URL structure stable while vendor coverage is being filled. A folder can be useful for routing and buyer intent before enough verified profiles are ready for ranking output.
