Integrate WhatsApp with öppen: AI agent for orders and inquiries
An AI agent can work with öppen by reading customers, products, stock and prices and loading orders, using whichever integration routes the ERP exposes. If you already use öppen's WhatsApp module, our agent comes in when you need more: custom rules, several systems at once, voice notes, photos and PDFs, and code in your account.

What connecting öppen to WhatsApp solves
öppen concentrates customers, catalog, stock and invoicing. When orders arrive on WhatsApp, the team acts as the bridge between the chat and the ERP. An agent takes over that bridge: it understands the order, validates against öppen and leaves it loaded or pending approval.
What the agent does inside öppen
All our agents talk to the system through a connector with the same interface. For öppen it is set up once and the agent always uses the same five operations.
| Operation | Example in a conversation | Read or write |
|---|---|---|
| Identify customer | Recognizes the buyer by their WhatsApp number and account. | Read |
| Search products | “Send me 20 boxes of yerba” is matched against your catalog, with codes and pack sizes. | Read |
| Check stock | Warns whether it is available before confirming and suggests alternatives. | Read |
| Check prices | Applies that customer's price list and terms, not a generic price. | Read |
| Create order | Builds the order from what was confirmed in the conversation and loads it into the system. | Write |
öppen's WhatsApp module or your own agent?
If all you need is to take text orders on öppen, the ERP's own module may be enough and is the simplest option. Your own agent is worth it when you need any of this:
- Several systems at once: öppen plus a supplier price sheet, a CRM or an in-house system.
- Custom rules: minimums by area, volume discounts, delivery days, blocked customers.
- Orders by voice note, photo of a list or PDF, not just text.
- Code and data in your account, so you don't depend on a single vendor.
- Modernizing the legacy system that still runs around the ERP.
How it writes to öppen without breaking anything
Reading is easy. Writing is the delicate part. That's why the agent never loads data blindly:
- Order pending approval: it reaches the system as a draft and a person confirms it. Once the team trusts it, you switch to direct loading by customer type or amount.
- No duplicates: every order carries a unique key from the conversation; if the customer repeats the message or WhatsApp retries delivery, it is not loaded twice.
- Audit trail: what the customer said, what the agent understood and what was written are all logged, so any order can be reviewed.
- Handoff: if an order is unusual (out-of-stock item, customer with a balance due, an amount outside the norm), it goes to a person with full context.
Timeline
An agent connected to öppen goes live in stages. Timelines depend on the available API and on how many products and pricing rules need to be covered.
| Stage | What happens | Time |
|---|---|---|
| Discovery | We review how öppen connects, the ordering flows and pricing rules. By the end you know scope and risks. | 1 week |
| Go-live | Agent running on your number, with orders pending approval and the team reviewing conversations. | 2 to 3 weeks |
| Tuning | With real conversations we tune products, synonyms and rules, and enable direct loading where appropriate. | Ongoing |
A note on transparency
We don't yet have an öppen case in production to show. That's why discovery validates each operation against a test environment before quoting, and we promise nothing we haven't verified there.
