Fastbill is available on request in the Binom dashboard: Integrations → More integrations → Fastbill. ## What Binom can do in Fastbill Binom here refers to your AI employee. After Fastbill is connected, it calls the service's actions when the conversation needs that data. You decide which actions it can use. In the dashboard, each action is marked: **read** (Binom only views data), **write**, or **delete** (Binom changes or deletes data in Fastbill). | Section | What Binom can view | What Binom can change | | --- | --- | --- | | Invoices | Invoices, recurring invoices | Create, complete, send by email or by post, mark as paid, cancel | | Estimates | Estimates | Create, send by email, convert to invoice | | Customers | Customers and contacts | Create and edit | | Income and expenses | Income, expenses | Create, mark as paid | | Projects and time | Projects, time tracking, products | Create and edit | ## Can the chatbot issue an invoice in Fastbill? Yes. Binom creates a customer ("Create Customer") and an invoice ("Create Invoice"), completes it ("Complete Invoice"), and sends it by email ("Send Invoice By Email"). ## Estimate with conversion to invoice Binom creates an estimate ("Create Estimate"), sends it ("Send Estimate By Email"), and after the customer agrees, converts it into an invoice ("Convert Estimate To Invoice"). ## What access you will need Connection method: API key. You will need your Fastbill email and API key. Details for each method are shown in the "Authentication" block on the Fastbill page in the dashboard. ## How to get the Fastbill integration Fastbill is connected on request: first, the Binom team sets up the integration for your account. General catalog rules are described in the instructions [how to connect a service from "More integrations"](https://binomai.com/faq/connect-service-to-chatbot/). 1. Open [Integrations → More integrations](https://app.binomai.com/cabinet/binom/integrations?tab=14), enter "Fastbill" in the "Search integrations" field, and open the Fastbill card. 2. The "Fastbill integration for assistant" page will show the message "Integration is available on request. Request it now, and we will set it up for you as a priority." The assistant here is your Binom. The "Authentication" block shows which access you will need, and the "Actions" list shows everything Binom can do in Fastbill. 3. Click "Request integration". The message "Request sent. You will receive a notification when the integration is available." will appear, and the button will change to "Requested". 4. A Binom setup specialist will contact you. When the integration is ready, a "Connect" button will appear on the Fastbill page. 5. Click "Connect", go through the steps in the "Connecting Fastbill" window, and click "Done". After "Connecting...", the status will change to "Connected". If "Confirmation has not arrived yet. The connection may still complete: check again in a minute." appears, click "Check again". ## How to choose what Binom can do in Fastbill A connected integration does nothing until you allow actions. The dashboard states this clearly: "Select the actions the assistant may call. Until something is selected, it has no access to any action." 1. On the Fastbill page, tick the actions you need in the "Actions" list. To find them by name, use the "Filter by actions" field. The counter shows how many are selected. 2. Check the "Ask before changing data" toggle. It is on by default: before any action that writes or deletes data, Binom will describe what it is about to do and wait for your confirmation. 3. Click "Save". The message "Allowed actions saved" confirms the changes. To start, "List Customers", "Create Customer", "Create Invoice" and "Send Invoice By Email" are enough. Add the actions for editing and deleting when you are ready to let Binom make changes in Fastbill. ## How to check that the integration works - Start a new conversation with your Binom, for example via the [public chat link](https://binomai.com/faq/public-chat-link/), and agree on a test service. Check the invoice in Fastbill. - Delete the test draft after checking. ## Possible problems ### Binom does not use Fastbill data in its answers **What to check:** that the Fastbill status is "Connected" and that the needed actions are ticked (for example "Create Customer"). **What to do:** tick the actions and click "Save". **How to tell it is resolved:** the message "Allowed actions saved" appears, and in a new conversation Binom answers using Fastbill data. ### "Could not save the request. Please try again." **What to do:** click "Request integration" again. If the message keeps appearing, write to support@binomai.com with the name of your Binom and the integration (Fastbill). **How to tell it is resolved:** the button shows "Requested". ### "Integration is temporarily unavailable - your request has been saved." Nothing more is needed: the request is saved, and you will receive a notification when Fastbill can be connected. ### "Reconnection required" **What it means:** "The service no longer accepts saved credentials, so the assistant does not use them." **What to do:** open the Fastbill page under [More integrations](https://app.binomai.com/cabinet/binom/integrations?tab=14), click "Reconnect" and go through the connection window again. **How to tell it is resolved:** the status is "Connected". ### "Could not start the connection. Please try again." **What to do:** click "Connect" again. If the message keeps appearing, write to support@binomai.com with the name of your Binom, the integration (Fastbill) and a screenshot of the message. **How to tell it is resolved:** the "Connect Fastbill" window opens. ### "Paid plan" instead of the connect button The page will show "Available on a paid plan. Tell us what you need, and we will let you know when it launches." For what is included in each plan, see the [plans and subscription prices](https://app.binomai.com/plans) page, and for how to change your plan, see the guide [how to change or upgrade your plan](https://binomai.com/faq/change-subscription-plan/). After changing your plan, return to [More integrations](https://app.binomai.com/cabinet/binom/integrations?tab=14) and open Fastbill again. ### "You do not have permission to manage this section." **What this means:** only users with the Owner or Admin access level can manage integrations. **What to do:** ask the account owner to give you the Admin access level or to connect Fastbill yourself. More details: [access levels in a team](https://binomai.com/faq/kak-raspredelit-obyazannosti-v-komande-s-pomoshhyu-pyati-urovnej-dostupa-owner-admin-editor-operator-viewer/). **How to tell it's resolved:** after you refresh the page, the integration settings open. If the problem persists, write to support@binomai.com or send "I want to talk to a person" in the chat with [Binom Tutor](https://app.binomai.com/cabinet/binom/binom-tutor-stream). Include the name of your Binom, the integration, and attach a screenshot of the message. ## How to disconnect Fastbill On the Fastbill page, click "Disconnect". The "Disconnect Fastbill?" window will show a warning: "The assistant will lose access to the service. To restore it, you will need to reconnect the integration and enter the credentials again." Confirm, and the message "Integration disconnected" will appear. ## Other common questions ### Do I need a programmer to integrate Fastbill? No. You request Fastbill in the [Integrations → More integrations](https://app.binomai.com/cabinet/binom/integrations?tab=14) section, the Binom team sets up the integration, and then you connect the account yourself and choose the actions. ## What's next - [Clear Books integration](https://binomai.com/integrations/clear-books-integration/)
