    Q: Has anyone faced real performance or scalability issues with Dynamics 365 Business Central at scale (100+ users, high transaction volumes)?

    Has anyone experienced real performance or scalability limits with Dynamics 365 Business Central in high-volume, enterprise-like environments (100+ users, heavy transaction loads)? What were the breaking points and how did you overcome them?

    At what point did you see slowdowns in posting, job queues, or inventory processing?

    Did custom extensions, integrations, or multi-company setups contribute to the problem?

    What were the breaking points, and how did you resolve them — optimization, architecture changes, or moving to another ERP like Dynamics 365 Finance or NetSuite?

    Looking for real-world experiences, not marketing answers.

    In some of my projects we were producing 3-4000 sales orders daily. Some documents had 20-30k lines.

    A few lessons I learnt:

    Your questions are generic but I found creating multiple no series and allowing gaps helped with deadlocks.

    Run processes via job queues.

    When processing in bulk commit after each entity processed.

    I had a custom sales pricing engine, so I bypassed via code the base app (default) sales pricing engine, and used my sales pricing engine. Use interfaces for that.

    Take advantage of isolation levels, review your queries use IsEmpty, SetLoadFields …

    Review missing indexes page and add keys where appropriate.

    Use automated testing for testing your processes and transactional volume.

    Ping me if you have specific questions.
