AI-powered warehouse software for construction

Material requests over WhatsApp, read by AI and ready to pick

Engineers write the request the way they already do. Zelo's AI finds the items in your company's catalogue and suggests quantities and a usage date. Once the engineer confirms, the request lands in the warehouse queue, and anything sent too late is flagged.

Features

What a material request needs to arrive on time

Catalogue, timing rules, picking queue, AI requests over WhatsApp, alerts and analytics. Every request carries who asked, for when and how far ahead.

AI requests over WhatsApp

The engineer sends the request in one message. The AI reads it, finds the items in the catalogue and proposes quantities and a date. The request is created only after they confirm.

Confirmed before it's created

Material catalogue

Codes, units and descriptions standardized across the company. Import your ERP spreadsheet in one go, then keep it current with the same file.

One code per company

Structured request

From 1 to 100 catalogue items, each with a quantity, plus a usage date and time and a priority. Every request gets your company's next sequential number.

Numbered per company

Cut-off and minimum window

Set the hour by which a request makes the plan, and how far ahead it must arrive. Anything outside that is flagged as unplanned.

Planned × last minute

Picking queue

Pending, scheduled, in progress, completed. The warehouse sorts by usage date or priority, and the engineer follows along without calling.

From request to pickup

Manager dashboard

The next 7 days' load, today's and tomorrow's peak hours, overdue requests and each engineer's lead time.

How it works

From catalogue to picked material, in four steps

The warehouse sets up the catalogue and the rules once. From then on the field team requests through Zelo and everyone sees the same queue.

Step 1 of 4 Catalogue
warehouse-materials.xlsx
Excel · 186 KB
1,284 materials validated
Unique codes Units checked Nothing half-saved

Catalogue · Warehouse

Import your material list from an Excel sheet — code, name, unit and description. The whole file is validated before anything is saved: if one row has a problem, nothing is half-saved.

Step 2 of 4 Team and rules
Request Pick Configure Team member Warehouse manager

Team and rules · Warehouse

The warehouse manager invites the team and sets the daily cut-off and the minimum lead-time window. The rules apply to every request from then on.

Step 3 of 4 Request

Request · Engineer

The engineer builds the request in Zelo or sends it over WhatsApp, where the AI proposes the catalogue items. Every request has a quantity, a usage date and time and a priority. If it arrives after the cut-off or with less notice than the minimum window, Zelo asks for a justification and flags it as unplanned.

Engineer notified at every change

Picking and analytics · Warehouse

The warehouse works from a single queue, sorted by usage date, priority or status. The engineer is notified at every change, and the manager sees on the dashboard where the load will peak.

Day to day

A queue your warehouse can actually keep

Fewer surprise requests in the morning, more picking done the day before — and numbers for the conversation with whoever always asks at the last minute.

  • No requests lost in the group chat.
  • No chasing calls.
  • No invisible queue.
Alerts

Every change reaches whoever needs it

New, cancelled or reopened requests alert the warehouse and management; status changes alert the engineer. Whoever made the change isn't alerted about it.

Load forecast

The next 7 days, day by day

How many requests are due on each day of the week, and which hours today and tomorrow the picking will bunch into.

Lead time

Who plans ahead and who asks at the last minute

Average lead time and unplanned rate for the engineers who request the most, measured against the rule in force when each request was sent.

On the phone

The queue fits in the warehouse keeper's pocket

On a phone the queue becomes cards grouped by usage date, with the same search and sorting. And Zelo can be installed as an app.

Pricing

You pay for picking volume. Not per user.

Plans differ only in the material lines included each month. Every item in a request counts as one line, and every feature, AI requests over WhatsApp included, is in every plan.

FAQ

The questions that come up before signing

Billing, inventory, AI, last-minute requests, the catalogue, phones and who can see your operation's data.

You choose a plan by the number of material lines per month — each item in a request counts as one line. We don't charge per user, so engineers, warehouse staff and managers join at no extra cost. Pricing is on request: tell us how many requests your operation handles a month and we'll send a sized quote.

It works on WhatsApp requests. When an engineer sends a free-text request, Anthropic's Claude model compares the message with the active materials in your catalogue and proposes items, quantities and a usage date. The engineer checks the proposal and confirms, and only then is the request created, under the same timing rules as a request placed in the app. We don't send phone numbers, user names or the company name, and the data isn't used to train AI models.

No. Zelo organizes the request and the picking: what was asked for, for when, how far ahead and where it stands. Stock levels, purchasing and invoicing stay in the system you already use — and Zelo's catalogue can be imported and updated from the spreadsheet that system exports.

The request goes through. Zelo doesn't block late requests: it asks for a justification, flags the request as unplanned with the reason (same day, after the cut-off or short of the minimum window) and carries that to the manager dashboard. The point is to make late demand visible, not to stop the job.

No. Download the template, fill it in or paste your ERP export, and import it. Each file, of up to 5,000 materials, is validated in full before anything is saved. To update later, re-import in update mode: existing codes take the new values and nothing is deactivated by omission.

Yes. The queue and requests work in a phone browser, and Zelo can be installed as an app. If your company turns it on, engineers can also request over WhatsApp: they link their number once, send the request in a single message, check the items the AI proposes and confirm.

Only the people your company invited. Each company has an isolated workspace, there is no open sign-up, and the roles that administer or pick require two-factor authentication.
