You've signed up for an AI voice agent. The platform asks you to upload a knowledge base. You stare at a folder with 47 PDFs, a dusty service menu from 2019, and a half-finished FAQ doc someone started during lockdown. Where do you actually start?

Most people either dump everything in at once or get paralysed and upload nothing. Both kill performance. A call we listened to last Tuesday had the agent confidently quote a price that changed six months ago because the owner uploaded every old document they could find. The customer hung up. Upload the right 20% first, and you'll handle 80% of calls correctly from day one.

The 30-minute starter pack

Your first knowledge base session should answer three questions: what you do, what it costs, and how someone books. That's it. In 30 minutes you can prepare:

• Service list with current prices. One page. If your pricing is complex, give ranges or starting points. "Consultation from $180" beats a silent agent.
• Opening hours and location. Include public holiday closures if you know them.
• Booking process. Do they book online, call back, or can the agent do it? State the steps clearly.
• Top 5 FAQs. Pull these from your actual inbox or the questions your current receptionist hears daily.

Format each as a question and a short answer. "Do you bulk bill?" gets a yes/no plus one sentence of detail. The agent reads exactly what you write, so skip the preamble. "We bulk bill Medicare card holders for standard consults" works. "Well, it's a bit complicated because sometimes we do but it depends on several factors" does not.

What to leave out in week one

Do not upload your full policy manual, your staff handbook, or your terms and conditions PDF. The agent doesn't need to know your sick leave policy or your supplier contract terms. It needs to handle customer calls.

Also skip anything time-sensitive that you won't remember to update. If you're running a March promotion, upload it in March and delete it in April. Stale offers destroy trust faster than no offer at all.

One plumbing business uploaded a 90-page franchise operations guide. The agent started explaining territory rights to customers asking about blocked drains. Strip it back. Customer-facing information only.

The 60-day expansion

After your first month live, you'll know what the agent struggles with. Listen to five random calls or read the transcripts. Look for moments where it says "I don't have that information" or gives a vague answer.

Now add the second layer:

• Common objections and edge cases. "What if I need to cancel?" "Do you come to my area?" "Can I get same-day service?"
• Product or service detail. If 30% of calls ask about a specific treatment or part, write a clean paragraph about it.
• Process clarifications. What happens after someone books? Do you send a confirmation email? Should they bring anything?

You're aiming for another 10-15 question-answer pairs. Keep the format identical to your first upload so the agent's response style stays consistent.

The 90-day audit and refresh

Set a calendar reminder for 90 days after go-live. Open your knowledge base and delete anything that's wrong. Prices changed? Update them. Stopped offering a service? Remove it. Hired someone new who handles bookings differently? Rewrite that section.

This is also when you add the final layer: edge policies and rare questions. Refund policy. Accessibility information. Parking instructions. These come up in maybe 5% of calls, but when they do, you want a clean answer ready.

A legal practice we work with adds one new knowledge item every Monday morning. It's a standing task for their practice manager. Over six months they built a base that handles 91% of intake calls without a human. They didn't do it in one weekend. They did it in small, deliberate updates.

Format mistakes that break AI reading

AI agents read text, not layout. Your beautifully formatted brochure PDF might render as gibberish. Before you upload anything:

• Test by copying the text into a plain notepad. If it looks scrambled, rewrite it as clean sentences.
• Avoid tables unless they're very simple. The agent can't parse a complex pricing grid. Write it out: "Standard service $200. After-hours add $80."
• No images with text. The agent can't see them.
• Delete headers, footers, and page numbers from PDFs. They confuse context.

Plain text question-answer pairs beat fancy documents every time.

What to do this week

Block 30 minutes. Open a blank document. Write your service list, your hours, your booking process, and your top five FAQs. Upload that. Go live. Listen to 10 calls in the first week. Add three more answers based on what you hear. Book another 30 minutes in 60 days to do the same thing.

Your knowledge base is never finished, but it doesn't need to be. It needs to be accurate, current, and focused on what customers actually ask. Start small. Update often. You'll be handling real calls correctly while your competitors are still trying to document everything.

Sign up at app.voxreach.com.au/signup and upload your first knowledge base today. Thirty minutes of work, then let the agent take your next hundred calls.
