When a Dash.fi customer wants to pay you through Dash.fi, they send you an invite by email. The link opens a short setup flow with four steps: **Sign in**, **Company**, **Details**, and **Vendor portal**. When you finish, the inviting customer is waiting in your portal as your first customer. ## Open the invite The invite page is titled **{Customer} needs your payment details**. It shows: * Any message the customer included with the invite. * **Requested by**: the customer who invited you. * **Sent to**: the email address the invite was sent to. * **Link expires**: the date the link stops working. Choose how to continue: * **Provide details**: Dash.fi emails a sign-in link to the invited address. Open it on the same device to continue. * **I already have a Dash.fi account**: sign in with your existing account. See [Signing in to Dash.fi](/account/sign-in). You must continue as the invited email address. If you're signed in as someone else, the page shows **Signed in as someone else**. Click **Sign out and continue** to switch to the invited address. ## Choose a company The **Set up the vendor portal for** step lists the companies your email address belongs to, plus **A new company**. The inviting customer sees the company you pick here. * Pick an existing company to set up its vendor portal. * Pick **A new company** to create a company with you as its first user. * If a company is marked **Already a network vendor**, click **Sign in** next to it. You then add the customer from that company's existing portal. Click **Continue**. ## Enter your company details The **Your company** step sets how you appear to the inviting customer and every other customer on the network. | Field | Required | | - | - | | **Business name** | Yes | | **Legal name** | No | | **What you do** | No | | **State** and **Country** | No. Provide both or neither. | If you chose **A new company**, you also enter your **First name**, **Last name**, and an optional **Middle name** and **Phone number**. Use the international format for the phone number, for example `+61 400 000 000`. Click **Set up my vendor portal**. Dash.fi shows a progress screen while it creates your portal. When setup finishes, the page reads **Your vendor portal is ready**. Click **Go to your vendor portal** to review what the customer asked for. If Dash.fi can't sign you in automatically, click **Sign in**. ## If you already run a vendor portal If your company already has a vendor portal, the invite page reads **Add {Customer}**. Click **Add this customer** to add them to your portal. You then answer their request from [Customers](/vendor-portal/customers). ## Invite problems | Message | What to do | | - | - | | **This link has expired** | Ask the customer who invited you to resend it. | | **This link is not valid** or **This invite no longer exists** | Check the link in your email, or ask the customer to send a new one. | | **Invite withdrawn** | The customer withdrew the invite. Ask them for a new one if you still want to connect. | | **You already have this customer** | The customer is already connected. Click **Sign in to your vendor portal**. | | **Setup failed** | Read the reason in the banner, correct the details, and try again. If the business name, country, or phone number wasn't accepted, fix that field. | This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
