Business Central Inventory Reconciliation & Fixed Asset Specialist — Diagnostic & Remediation

Summary Manufacturing company running Microsoft Dynamics 365 Business Central needs an experienced BC/ERP consultant to diagnose and resolve a significant, ongoing disconnect between inventory-related General Ledger accounts and inventory sub-ledger reports. The variance began after a migration from Dynamics NAV to Business Central and has persisted for roughly 18 months. Background - Migrated from NAV to Business Central; inventory GL accounts have not reconciled since. - Historically, reconciliation was done manually each month via spreadsheet and stayed in balance — it went untested through the migration and has been out of balance since. - Direct posting to inventory GL accounts is disabled at the setup level, so the root cause is suspected to be a mapping or configuration issue introduced during migration rather than manual override. - Known symptoms include mismatched received-not-invoiced and shipped-not-invoiced balances tied to closed POs/SOs, and inconsistencies in how items are coded between raw materials and finished goods. - Current variance is significant (six figures). - A related, lower-priority need: the Fixed Asset module was never fully implemented — assets are currently tracked and depreciated in a spreadsheet, then posted manually. Scope of Work - Diagnostic phase (primary/urgent): audit inventory posting setup (posting groups, general posting setup, costing configuration); review item ledger entries, value entries, and GL entries to trace the variance to its source; investigate flagged discrepancies; quantify the variance on a per-month basis to support a one-time balancing adjustment as of the start of the fiscal year. - Second phase (separate engagement, lower priority): implement the Fixed Asset management module, including depreciation schedules, replacing the current spreadsheet-based process. Requirements - Strong hands-on experience with Business Central (and ideally NAV) inventory, costing (FIFO/Average/Standard), and fixed asset modules - Experience specifically with inventory-to-GL reconciliation and post-migration cleanup projects - Comfortable working independently in a sandbox/staging environment with a copy of production data - Manufacturing or distribution industry experience preferred - Strong communicator — client wants clear root-cause explanations, not just fixes Engagement Structure - Starts as a short, hourly diagnostic contract (not-to-exceed without check-in), transitioning to a fixed-scope remediation contract once root cause is confirmed - Fixed Asset module implementation to be scoped separately afterward
