01Team access
Every colleague gets the access their job needs.
Access is set per area of the app, at four levels: none, view, edit and full. Start from a role, or set the areas one by one for a colleague.
NoneViewEditFullEach level includes the ones before it.

02Companies
Several companies, one login.
Construction groups often trade under more than one company. On Greyn, one person can belong to several and switch between them.
- Switch the active company — listings, orders, inventory and payouts always belong to the company you are working for at that moment.
- Each company stands on its own — with its own team, locations and Stripe account, so sales and payouts never mix.
- Add a company yourself — create another company from your account and invite its team.
- Conversations belong to the company — colleagues who buy or sell for it see the same conversations, so anyone can pick up where someone else left off.
03Stock and sites
Know what you have, and where it is.
Every company gets a free inventory, also before it sells anything. Keep it current, and put an item on the market the day you no longer need it.
04Purchasing
Buy against your purchase order.
Upload a purchase order as a PDF. Greyn reads the materials and quantities and looks for matching listings.
Upload the order
Drop in the PDF. Greyn picks out each material with its quantity and unit.
Review the matches
See per line what is available, from whom and at what price, and add it all to the cart in one go.
Get alerted for the rest
Turn lines without a match into saved searches and hear as soon as matching stock is listed.
NoteA price offer made to your company can be accepted and paid by any colleague who buys for it.

Yes. The inventory imports an Excel template (or a CSV file), and you can export it, change it and import it again to update your items. For a large stock list or a demolition inventory, the Greyn team can turn it into draft listings for you to check.
