Problem · Integration

I have several tools and none of them talk to each other

Isolated tools force someone to copy data from one screen to another — and that manual trip is where information gets lost. Integrating doesn't mean connecting everything to everything: it means deciding which system owns each piece of information and having the others read from it.

CRM on one side, ERP on the other, WhatsApp in a third place, a spreadsheet stitching it all together and one person copying data from one system to another. Each tool works; the whole doesn't.

How to solve it, step by step

  1. List where each piece of information is born. Customer, opportunity, order, payment. For each one, name a single system as the source of truth.
  2. Find the manual work. Every time someone retypes something that already exists on another screen, there's an integration missing right there.
  3. Start with the integration that hurts most. It's usually the one connecting the conversation to the sale: WhatsApp and CRM. Integrating everything at once rarely gets finished.
  4. Prefer official integrations. Documented APIs and webhooks survive updates. Fragile automations break silently and nobody notices for weeks.
  5. Monitor the integration. Set up alerts for sync failures. An integration without monitoring is one that has already stopped and you don't know it yet.
  6. Don't automate what needs judgment. Negotiation, exceptions and winning back an unhappy customer stay human. Automating them creates a new problem.

How this problem shows up

The cost shows up disguised as routine:

  • Someone exports a spreadsheet from one system and imports it into another every week
  • The same customer exists with different data in three places
  • Nobody knows which system has the correct information
  • Reports need manual consolidation before every meeting
  • A typo turns into a billing problem

Why it really happens

The tools were bought one at a time, each solving a specific problem well — and none of them was chosen with the whole in mind. It's accumulation, not a bad choice.

The manual work between them is usually invisible in the numbers: it doesn't show up on any invoice, but it eats hours of expensive people and introduces errors exactly where they're hardest to catch.

What changes once it's fixed

Data starts flowing on its own. Information is entered once and shows up wherever it's needed, with no exports, no copying and no conflicting versions.

As a result, reporting stops being a weekly project and becomes a lookup — and the operation stops scaling by hiring people to plug integration gaps.

How Nexo fixes it

Nexo builds proprietary software and integrates third-party systems. When a ready-made integration exists, it uses it; when it doesn't, it builds one.

  • Mapping which systems really need to exchange data — and which don't
  • Integrations via API, webhooks and automations
  • Defining which system is the source of truth for each piece of information
  • Custom development when no connector is available

Frequently asked questions

Do I need to replace all my systems?

In most cases, no. Replacing a system is expensive and risky; integrating usually solves the real problem, which is data not flowing.

What if my ERP is old and has no API?

There are options even without a modern API. The technical assessment defines what's feasible, and at what cost, before any promise is made.

Do integrations break when the system updates?

It can happen, which is why integrations need monitoring and maintenance — part of ongoing operations, not a one-time delivery.
