30 prompts to run your merch program from Claude or ChatGPT

Copy them, change the numbers, and run them in Claude, ChatGPT or Gemini with Sunday connected. Grouped by the job you're trying to get done.

Part of our complete guide to Sunday MCP: manage your merch from Claude, ChatGPT or Gemini.

Sunday MCP use cases fall into eight jobs: budgets, stock, reorders, onboarding, events, gifting, reporting and creative ideas. The 30 prompts below work in Claude, ChatGPT or Gemini once Sunday is connected. The agent prepares suggestions, plans and quotes. A person on your team approves every order and confirms every shipment.

The hard part of using an AI assistant for merch isn't the technology. It's knowing what to ask. So here's a starting set, written the way people on marketing, HR and ops teams actually talk. Swap in your own numbers, offices and audiences.

How should you use these prompts?

First, connect Sunday. Add it as a custom connector in your assistant using the URL you receive, then sign in with your Sunday account. The setup guide has the details. No Sunday account yet? Create one for free.

Then keep one thing in mind. Every prompt ends in one of three places: an answer, a suggestion or a quote. None of them ends in an order placed by the agent.

Here's what one of those exchanges looks like in practice.

You, in Claude · Illustrative example: How many black hoodies do we have left in stock, by size?

Sunday MCP: Here's your current black hoodie stock by size from your Sunday inventory. Medium and large are your lowest. Want me to prepare a reorder quote for those two sizes? You'd approve it through a link before anything is ordered.

Budgets: what should we spend, and on what?

Assembling budgets is the most tedious merch task there is, and the first one worth handing over. With one prompt the assistant searches the whole catalog, looks at what's popular and comes back with a split you can react to.

• 1. "We have 20,000 euros for merch this year and about 300 employees across three offices. Suggest a budget split by item and occasion, based on what's popular in the catalog."
• 2. "Build a wish list of eight items under 40 euros each that would suit a developer audience, and give me a link I can share with my team."
• 3. "Calculate the price for 150 embroidered caps and 150 printed T-shirts, and show me how the price per unit changes at 300."
• 4. "I have 5,000 euros for client gifts this quarter. Suggest two pack options at different price points and tell me how many of each that covers."

Stock: what do we actually have?

These are the safest prompts to start with. Read-only, instant, and they replace the "can someone check the warehouse" message.

• 5. "How many black hoodies do we have left in stock, by size?"
• 6. "Which items in our stock are below 50 units?"
• 7. "Show me everything in stock that we haven't shipped in the last six months."
• 8. "Do we have enough T-shirts in stock to cover 120 new hires next quarter, or do I need to reorder?"

Reorders: one prompt, one quote

Reorders are where agents will take over first. Niels Vandecasteele at Sunday puts it this way: "New products is a creative project. Reordering is an administrative transaction." Each of these comes back as a quote for someone to approve.

• 9. "Create a quote to reorder the pants we ordered last spring, same quantities."
• 10. "Reorder our onboarding kit for 40 people as a quote and send it to me for approval."
• 11. "We're running low on notebooks. Prepare a reorder quote for 500, same design as last time."
• 12. "Prepare two reorder quotes for our hoodies, one for 200 and one for 400, so I can compare the unit price."

Onboarding: kits for new hires

Claude for HR mostly looks like this: less spreadsheet, fewer emails to the office manager. For the program side of welcome kits, see new hire welcome kits.

• 13. "Suggest a pre-made welcome kit for new engineering hires, under 80 euros per person."
• 14. "Plan shipments of the welcome kit to the five new starters in this list, in Berlin, Lisbon and London. Show me the plan before anything ships."
• 15. "What does it cost to send one welcome kit each to Germany, Spain and the United States?"

Events: forecast before you run out

Say your team hands out 1,000 to 1,500 items per event. The assistant can turn your event calendar into a forecast and the quotes to match. More on planning event kits in event merchandise.

• 16. "We hand out 1,000 to 1,500 items per event and have four events next quarter. Build a forecast and prepare quotes to cover the quarter."
• 17. "Suggest event giveaways under 5 euros per unit that people actually keep, for a fintech conference audience."
• 18. "Plan a shipment of 400 T-shirts and 400 tote bags to our booth address in Amsterdam, and tell me what I need to confirm."
• 19. "How many items did we ship for our last three events, by product?"

Gifting: who gets what

Gifting is one part of what Sunday MCP does. These prompts get stronger when your CRM is connected to the same assistant, which prompts 21 and 22 assume. If you're building a repeatable program, start with our guide to corporate gifts.

• 20. "Send these three customers a nice gift. Suggest what, and show me the quote before anything goes out."
• 21. "From our CRM, find the customers where a gift would have the most impact right now. Then ask Sunday what to send each of them."
• 22. "This is our leftover stock in Sunday. Based on our CRM and HR data, which customers or employees should we reward with it?"
• 23. "Suggest a thank-you gift for a partner agency team of 12, using items we already have in stock."

Reporting: answers without the export

Data questions that used to mean a dashboard login or a request to your account manager.

• 24. "How many items did we ship last quarter, and to which countries?"
• 25. "What are our most popular shipping countries this year?"
• 26. "Request a report of everything we ordered this year, so I can share it with finance."
• 27. "Which products do we reorder most often?"

Creative: ideas without browsing the catalog

This is where the real value sits. The platform already saves the admin time. What the assistant adds is ideas that fit your audience, without you scrolling through the full catalog.

• 28. "Suggest five merch ideas for our summer offsite that fit a young, design-minded team. Skip the mugs."
• 29. "Request a design for a hoodie and a matching beanie with our logo, in our brand colours."
• 30. "We're launching a new product in May. Suggest a small kit for 50 key customers that ties into the launch, with a price per kit."

Design requests go to a person for sign-off against your brand guidelines. For the full creative flow, from idea to mockup to approved quote, read AI merch design. For longer scenarios that string several of these prompts together, see 12 agentic AI examples in merch and gifting.
