AI POS Software / Setup guide

Connect Invoay SimplePOS to your AI app with MCP (Model Context Protocol). Then ask about sales, stock, customers and staff in plain language.

You only do this the first time. After that, just open your AI app and ask.

Step by step
Choose your AI app
Menu names in AI apps change often. If a step looks different, our team will walk you through it on a short call.
Connect Invoay to Claude
- Open claude.ai on the web or the Claude desktop app.
- Go to Settings → Connectors (on some accounts it is Customize → Connectors).
- Click Add custom connector.
- Name it Invoay and paste the Invoay MCP server URL our team gave you. Click Add.
- Click Connect and sign in with your Invoay login when asked.
- Start a new chat and ask: “What were my total sales yesterday?”
Plans
Custom connectors work on Free, Pro, Max, Team and Enterprise. Free allows one custom connector.
Team or Enterprise
An Owner adds it once in Organization settings → Connectors. Members then click Connect.
Connect Invoay to ChatGPT
- Open chatgpt.com on the web (custom connectors are added on the web, not the mobile app).
- Go to Settings → Apps (shown as Apps & Connectors on some accounts) and open Advanced settings.
- Turn on Developer mode. On Business or Enterprise workspaces, an admin may need to allow this first.
- Go back and click Create to add a custom app. Name it Invoay and paste the Invoay MCP server URL.
- Choose OAuth if asked, then sign in with your Invoay login.
- In a new chat, turn on the Invoay app and ask: “Which items are running low?”
Plans
Custom MCP apps use developer mode. Availability depends on your plan; admins control it on Business and Enterprise.
Safety
ChatGPT asks for confirmation before an app runs an action that changes data.
Connect Invoay to Gemini
- Open gemini.google.com on the web.
- Go to Settings → Connected apps → Custom apps and choose Add a custom app.
- Paste the Invoay MCP server URL and click Next.
- Sign in with your Invoay login and approve the connection.
- Ask: “Compare this week’s sales with last week.”
Availability
Google currently limits custom apps by country and account type, with Gemini set to English.
Gemini Enterprise
Your Workspace admin adds Invoay as a Custom MCP Server for the organisation.

Your first 5 questions
Ask these right after connecting. Want more? Open the question library.
- What were my total sales yesterday, and how does that compare with last week?
- Which 10 items are running low?
- Who are my top 20 customers this year?
- Which staff member had the highest sales this month?
- Which customers haven’t visited or bought in 60 days?
Troubleshooting
If something doesn’t work
No option to add a custom connector
Use the web version, check that your plan allows custom connectors, and on team plans ask the workspace owner or admin.
Connected, but the AI doesn’t use Invoay
Turn the Invoay connector on in that chat, and in ChatGPT check that developer mode is on. Mention “in Invoay” in your question.
Sign-in fails
Check that you use your Invoay login and that MCP is turned on for your account. Contact our team if it still fails.
Numbers look different from reports
Tell the AI the exact branch and date range. If it still differs, share the question with our team so we can check.

Talk to our teamDo I need to know coding to connect Invoay to an AI app?
No. Our team turns on Invoay MCP and gives you a server URL. You paste it into your AI app’s connector settings and sign in with your Invoay login.
Which AI app is easiest to start with?
Claude is usually the simplest: custom connectors are available on its plans, including one connector on the free plan. ChatGPT needs developer mode, which depends on your plan. Gemini custom apps are currently limited by country and account type.
Can I connect from my phone?
Add the connector once on the web or desktop app. After that you can use it from the mobile app of Claude, ChatGPT or Gemini.
Can the AI change my data in Invoay?
Our team will confirm what your Invoay MCP connection can do when they set it up. AI apps ask for your confirmation before running actions that change data.
How do I disconnect?
Remove or disconnect the connector in your AI app’s settings at any time, or ask our team to turn off MCP for your account.
The connector option doesn’t appear. What should I do?
Use the web version, check that your plan allows custom connectors, and on team plans ask your workspace owner or admin. Menu names change often, so our team can guide you on a short call.
