Why Demos Lie (and How to Know)
Every AI automation vendor will show you a polished workflow running flawlessly on their sample data. The sales engineer clicks one button. A bot extracts invoice data. A CRM record updates. You nod. You feel confident.
Then you go live in your environment with your messy, real data.
The bot halts on PDFs it wasn't trained to see. The API integration fails because your legacy system uses nonstandard field naming. The workflow succeeds 87% of the time, not the 98% promised. Your team spends week two debugging instead of reducing headcount.
This is the gap between demo and delivery. Most vendors close it slowly—if they close it at all. The smartest ops leaders now demand proof within the first 72 hours.
The 72-Hour Proof Test: What to Demand
1. A Working Bot on YOUR Data (Not Theirs)
Tell the vendor: "I'm giving you a sample of our actual invoices, support tickets, expense reports—whatever process you're automating. Build and test the first workflow on this data. Show me success metrics by Thursday."
This reveals two things immediately. First, does the vendor have the technical depth to handle your edge cases? Second, are they willing to work fast, or do they need two weeks to "align on requirements"?
2. Documented Failure Modes
Ask: "What will the bot NOT handle? Where does it need human review? How often?"
A vendor who's honest about failure modes is a vendor who's built real systems. They'll say things like: "Multi-page contracts where OCR confidence is below 85%, we route to your team. Handwritten signatures, always manual. Column-order variations in spreadsheets, we catch and flag."
Vendors who promise 100% automation without exceptions are selling fantasy.
3. Integration Proof, Not Promises
By hour 72, you should see the bot's output landing in your actual system—your CRM, ERP, or database. Not in a staging environment. Not in their sandbox. Yours.
If they can't connect and sync within three days, your timeline just expanded by weeks.
What Success Actually Looks Like in Week One
A vendor that ships a working prototype on your data in 72 hours isn't just faster. They've already identified the structural problems in your process that will make or break automation.
By end of week one, you should have:
A documented workflow with clear handoff points between bot and human.
A baseline on throughput: "The bot handles 120 invoices/day. 15 escalate for review. 3-5 require rework."
Clear ROI math: "At your current cost per transaction, this workflow saves $X per month when running at this volume."
A backlog of month-two improvements: better OCR, new data sources, expanded scope.
You should NOT have vague timelines, promises to "finalize technical architecture," or hopes that the bot will magically improve over time.
Red Flags During the 72-Hour Window
If the vendor says any of these, move on:
"We need more time to understand your process" — they should understand it from documentation and your sample data.
"This will require custom development" — for a proof of concept, it shouldn't. Use standard connectors and workflows.
"We'll show you results after integration" — results come first. Then integration.
"You need to clean your data first" — good vendors handle reasonable data quality. If your data is truly unusable, that's a business problem, not a vendor excuse.
Work with Us on This
At Modulus, we run the 72-hour proof test by default. Week one, you get a working AI automation prototype on your actual process, your actual data, with documented edge cases and clear ROI metrics. We connect to your systems immediately—no staging theater. We show failure modes honestly. By Friday, you know whether this works for you or whether we need to pivot.
This approach is for ops leaders managing invoice automation, expense processing, ticket triage, data entry, qualification workflows, or any high-volume back-office process where manual work is eating budget. You're tired of vendors overselling and underdelivering. You want working software, not pitch decks.
If you're comparing automation vendors right now and want a partner who ships fast and measures success in days not months, let's talk. We'll begin with your process, your data, and your timeline—and you'll have proof within 72 hours of whether this is the right fit.
Start here: AI Automation & Custom Workflows. Book a call with our team, send us your sample data, and let's run the proof test together.
