CUSTOM SOFTWARE

Software built around the way your business works.

We build client portals, internal tools and CRM workflows connected to the systems you already use. Start with one process your team can test and validate.

Scope, schedule and investment are agreed after diagnosis.

THE PROBLEM

Disconnected tools leave your team doing the same work twice.

We define the process the software needs to support, the deliverables and third-party dependencies. You know how each stage will be validated before implementation starts.

  1. 01

    Spreadsheets used as the operation's primary record

  2. 02

    CRM, ERP and service channels without a reliable shared workflow

  3. 03

    Repeated tasks that depend on manual checks and handoffs

  4. 04

    Business rules spread across people, spreadsheets and tools

  5. 05

    Teams lose context when work moves between systems

  6. 06

    An off-the-shelf tool covers part of the process but blocks the rest

SYSTEM TYPES

Build the parts your operation needs.

Start with a concrete journey. The technical design follows its owners, data and exceptions.

Revenue and relationships

  • CRM pipelines and follow-up rules
  • Client portals
  • Marketplaces
  • Sales workflows

Operations and control

  • Back offices
  • Operational dashboards
  • Permissions and approvals
  • Process auditing

Data and integrations

  • Integration layers
  • Event-driven workflows
  • Data consolidation
  • Observability

PROJECT FIT

Start with a process your team can validate.

A good fit when

  • Operations with a recurring process and clear impact on revenue, capacity or quality
  • Businesses that already use systems and need to connect them without replacing everything at once
  • Teams with an owner who can make decisions, validate the work and provide system access
  • Projects that can start with a defined journey and acceptance criteria

A poor fit when

  • Hourly developer allocation
  • Open scope without an internal owner or clear priority
  • Replacing an entire operation without diagnosis, access and a rollout decision

CUSTOM INTEGRATIONS

Connect the tools your business already uses.

We build the layer that connects APIs, webhooks, data and operating rules. Depth depends on each provider's access, permissions and limits.

CRMs

ERPs

Payment gateways

Logistics

Internal systems

When a scope includes WhatsApp or agents, messaging and agent infrastructure is available. Syntesi builds the custom integrations with your systems and operating rules.

PROCESS

Each phase defines what is included, how we validate it and what comes later.

  1. 01

    Diagnosis

    Map the process, its owners, the systems involved and the risks of the first stage.

  2. 02

    Workflow & metrics

    Define the steps, exception handling, events to track and acceptance criteria.

  3. 03

    Build

    Deliver demonstrable increments with repository access and documented decisions.

  4. 04

    Controlled rollout

    Prepare the environment, permissions, required data and a gradual production release.

  5. 05

    Measurement

    Review events, failures and usage to see whether the workflow operates as agreed.

  6. 06

    Evolution or handoff

    Deliver documentation, prepare your team to continue and agree whether there will be another phase.

PROJECT PRICING

SCOPE AND INVESTMENT

We quote the work after diagnosis, based on the process, integrations, data and delivery requirements. The proposal lists deliverables, acceptance criteria, dependencies and responsibilities before development starts.

AGREEMENTS AND HANDOFF

Scope, ownership and handoff agreed before delivery.

Project scope and milestones, acceptance criteria and responsibilities are agreed before delivery. The client receives the project code, subject to third-party licenses, and repository access as agreed.

COMMON QUESTIONS

Questions to answer before deciding.

Do you work for a fixed project fee?

Yes. We organize the project around deliverables, milestones and acceptance criteria. We assess significant scope changes before implementation.

Does the client own the code?

The client receives repository access and the code developed for the project, subject to disclosed third-party components and licenses.

Do you replace an existing CRM or ERP?

It depends on the bottleneck. Integrating, modernizing or adding an operational layer often solves the issue better than replacing an entire tool.

How do you handle third-party integrations?

We map APIs, webhooks, permissions, limits and responsibilities before agreeing on the scope. Provider and client access dependencies are listed in the proposal.

Can we start with one part of the operation?

Yes. A focused pilot addresses one defined journey and lets the team validate the integration, workflow and acceptance criteria before expanding the platform.

Do you continue after delivery?

We can agree on a managed evolution phase or finish with a documented handoff and repository access. The choice is explicit in the scope.

Do you guarantee operational results?

We agree on the contracted deliverables and acceptance criteria. Operational results also depend on data, adoption, internal decisions and third-party systems.
