The problem

Deals and renewals depend on conversations nobody can see.

In high-ticket sales the real work happens in WhatsApp threads, email, site visits and the heads of your best people. The owner learns about a cold buyer or a slipping account after it is lost.

Follow-up lives in personal phones

Hundreds of leads, many agents, and no shared picture of who was promised what and when.

Knowledge leaves with the person

When a sales rep or account manager moves on, the history of the client moves with them.

The owner is the bottleneck

Status comes from asking around. Reports arrive late, built by hand, already out of date.

The product

One place where your team, your clients and your AI assistants work together.

Eratu is a ready AI-powered ERP that we adapt to your business in weeks: your brand, your workflow, the modules you need and nothing you do not. You own it. The AI reads the communication, keeps a timeline per client, writes summaries and follow-ups, and briefs you every morning.

Morning briefing · 07:00
Good morning, Pak Budi. Three things for today:
  • Melati cluster: 2 buyers not contacted for 5 days. Rina has the task.
  • PT Sinar Abadi: quote opened 3 times, no reply yet. Suggest a call today.
  • Team: 7 tasks done yesterday, 4 due today.

Sample briefing. Names and numbers are fictional.

  • Clients and dealsEvery lead, buyer or account, its stage, its history and its next step.
  • Communication monitorWhatsApp, email and meeting notes in one timeline, summarised by AI, with what needs attention flagged.
  • Tasks per clientWho does what by when, created by people or by the AI from the conversation.
  • Documents and proposalsQuotes, offers and reports drafted from your own data in your own format.
  • Owner briefingEvery morning on your WhatsApp: what moved, what is going cold, what needs you.
  • Your modulesPayment schedules, unit stock, visit plans, anything specific to how you sell.

How we start

Audit and Demo: see your own company in the system within ten days.

Instead of a generic demo, we build a working version with your name, your sample clients and your real conversations. You decide with evidence, not with slides.

  1. Day 1Discovery session, 60 to 90 minutesYou and your sales or account lead. What you sell, who talks to whom, where deals and renewals get lost.
  2. Day 2 to 3Your sample dataA spreadsheet of clients or leads, two or three exported WhatsApp threads and one proposal. You choose the sample. A one-page NDA is signed before anything is shared.
  3. Day 5Your demo instanceYour brand, your clients loaded, your conversations summarised by the AI with next steps and flags.
  4. Day 5 to 9Five mornings of the owner briefingOn your WhatsApp, built from your sample.
  5. Day 10Audit report and fixed quoteWhere communication leaks, the module map for your version and a fixed price for the build.

The demo instance stays live for 14 days. It then becomes the first version of your system, or it is deleted together with your data. Deletion is written into the NDA.

Always included

  • Every module, including the ones we release later, at no extra cost
  • An AI assistant that knows your company and respects each employee’s access rights
  • Client hub, referral programme and documents in Indonesian
  • 90-day guarantee: the first-quarter licence is refunded if the team does not use it

The first ten companies become Founding Partners: locked price, double AI quota, extra implementation hours.

After the demo

Implemented in weeks, subscribed while it pays off, owned when you want.

Implementation

fixed packs

Your demo becomes the live system: vocabulary, stages, templates, real data, team training. Packs of 10, 25 or 60 hours at a fixed price, no hourly billing.

Subscription

per seat per month

All modules, updates and plan support. Configuration requests are included; improvements useful to other clients we build for free; your custom modules at a fixed price.

Own server

same seat price

Run it on your server at the same seat price. A perpetual licence equals 30 months of subscription, and every 12 months of subscription already grant a perpetual right to that version.

Why weeks, not a year

Building a system like this from scratch takes one senior developer a year. Eratu starts from a core that already runs, so your version runs in weeks, and every new client makes that core stronger for everyone.

Why Eratu

Eratu runs on Eratu.

The core was born from the platform that has run our own agency since 2024: clients, tasks, documents and team communication across two countries. Today Eratu is its own first client: leads, contracts, invoices and your implementation are managed inside the same system you see below.
