Complex projects

Business Central for organizations that aren't simple.

Many companies, many currencies, many users and many connected systems. Cateran designs and leads Business Central projects where the architecture matters — and where getting it wrong is expensive.

Discuss your project

Multi-company finance

Intercompany processing, consolidations, multi-currency accounting and dimension design that gives the CFO one version of the truth.

High user counts

Experience with clients from 5 to 200+ concurrent users — permissions, performance, roles and rollout planning that hold up at scale.

Multinational scope

Multinational projects spanning countries, currencies and teams, including on-site consulting in Ireland, Germany, and Japan.

Integrations

Connected systems that don't need babysitting

Integrations are where many Business Central projects quietly fail: no error handling, no monitoring, and staff re-keying what didn't sync. Cateran designs integrations with ownership, logging and recovery built in.

  • E-commerce: Shopify
  • Payroll & HR: ADP
  • Expenses: Concur
  • Reporting: Power BI, Jet Reports, financial reporting
  • Custom systems via Business Central APIs and web services
Development

Extensions built to survive upgrades

When standard Business Central isn't enough, Cateran builds AL extensions — tables, pages, codeunits, reports and APIs — designed to stay compatible as Microsoft ships updates twice a year.

  • AL extensions and custom APIs
  • Conversion of legacy C/AL code
  • Reports and document layouts
  • Data conversion and automation
  • Code review of work by other partners
How complex projects are led

A senior team. One point of accountability.

Complex projects are delivered by Cateran's senior team of developers, functional consultants, and integration and reporting specialists, led by the principal architect who owns the design and the delivery.

Assess

Map entities, users, systems and data flows, and find the constraints: close calendar, audit cycle, peak seasons.

Architect

Company structure, chart of accounts, dimensions, integration ownership and security, designed once and documented.

Build in workstreams

Finance, operations, integrations and reporting run in parallel against one design, with one person accountable for how they fit together.

Roll out in phases

Go live by company, region or process where it lowers risk, with monitoring in place before each cutover.

How Cateran works
Warning signs

Is your setup more complicated than it should be?

Complexity in the business is normal. Complexity in the system usually means an early design decision needs revisiting.

  • Consolidation and eliminations are done in Excel every month
  • Intercompany balances don't agree without manual adjustments
  • Each company uses different dimensions, so reports don't roll up
  • Staff re-key orders, invoices or payroll because an integration failed silently
  • The system slows down at month-end or when certain jobs run
  • Nobody is sure what the custom code does, or whether it will survive the next update

Complex project questions

Can Business Central handle 200 or more users?

Yes, with the right design. At higher user counts, permission sets, background job scheduling, integration volumes, reporting load and rollout planning all need deliberate attention. Cateran has led Business Central and NAV projects with 200+ concurrent users.

Can we run several companies in one Business Central environment?

Yes. Business Central supports multiple companies in one environment, with intercompany transactions and consolidation into a group company. The key decisions are which entities need their own company, a shared chart of accounts, and standard dimensions.

Does Business Central support multi-currency and consolidation?

Yes. Each company can have its own local currency, with an additional reporting currency if needed. Consolidation handles currency translation and intercompany eliminations. Exchange rates, frequency and elimination rules should be designed up front.

Can you integrate with a system that isn't listed here?

Usually, yes. Business Central exposes standard and custom APIs, so most modern systems can be connected. The design work is in deciding which system owns which data, how errors are handled, and who is alerted when something fails.

Can you take over custom code written by another partner?

Yes. Cateran reviews existing AL extensions and legacy C/AL code for quality, upgrade risk and performance, then recommends what to keep, fix or replace. You should have the full source code for anything written for you.
