Microsoft Dynamics 365 Bookkeeping Services & ERP Accounting

Microsoft Dynamics 365 is a real ERP with a real general ledger — Business Central for small and mid-sized organizations, and Dynamics 365 Finance with Supply Chain Management for the enterprise. Your implementation partner set it up; somebody still has to run it every month. Dimensions, posting groups, cost adjustment, bank reconciliation and the close are where Dynamics books quietly go wrong, and Microsoft even provides free External Accountant licenses so a firm like ours can work inside your tenant. That monthly discipline is what we do.

Which Dynamics 365 Are We Talking About?

One clarification up front, because the naming trips everyone: Microsoft 365 is the productivity suite — Word, Excel, Outlook, Teams. The ERP line is Dynamics 365, and two products matter for bookkeeping. Dynamics 365 Business Central is Microsoft’s business management solution for small and mid-sized organizations and the upgrade path from Dynamics NAV. Dynamics 365 Finance and Dynamics 365 Supply Chain Management — the “finance and operations” apps, successors to Dynamics AX — serve enterprise and multi-entity organizations. There is no longer a single product sold as “Finance and Operations.”

If you are still on Dynamics GP (Great Plains): Microsoft has announced end of support, with product support ending December 31, 2029 and security updates ending April 30, 2031, and names Business Central as the recommended path. GP is in a published wind-down, and the migration wave is real — we keep books on both sides of it.

Both Business Central and Finance are true books of record: full chart of accounts, dimensions, multi-currency (Finance posts a reporting currency on every transaction and it cannot be turned off), intercompany, fixed assets with separate tax and book depreciation, and bank reconciliation with statement import and auto-matching. The capability is not the question. The configuration and the monthly discipline are.

Where Dynamics 365 Books Go Wrong

Dimensions set up casually, regretted permanently. Business Central gives you two global and up to eight shortcut dimensions, and Microsoft’s own guidance is to choose them carefully because changing global dimensions later forces updates across all posted entries. A dimension scheme that grew ad hoc produces a P&L by department or project that nobody trusts. In Dynamics 365 Finance the same failure lives in financial dimensions and account structures.
Posting groups decide your GL, silently. In Business Central, general, inventory, customer, vendor, bank, fixed asset and tax posting groups determine which accounts every transaction hits — and Microsoft’s documentation recommends consulting an accountant before creating them, because a wrong mapping posts revenue, COGS or inventory to the wrong accounts with no error message anywhere.
Inventory cost that hasn’t been adjusted isn’t a cost. Business Central’s cost adjustment (the Adjust Cost – Item Entries process) forwards changed inbound costs to outbound entries; until it runs, inventory value and COGS are simply inaccurate. Companies that turned automatic adjustment off for performance and never scheduled the batch job are reporting wrong margins.
Bank rec automation has documented limits. Feeds and auto-matching help, but Microsoft documents cases the automation does not handle — and posting directly to the bank G/L account breaks the connection with bank ledger entries altogether. Intercompany eliminations in Business Central are manual journal entries — the eliminations report only previews them. Deferral templates, US sales tax areas layered from state, county and city jurisdictions, and the Close Income Statement year-end process all work beautifully and all need a human who runs them correctly, every period.

Core Dynamics 365 Bookkeeping Functions We Manage

1. Monthly Close, Run as a Calendar

Posting-period controls, pre-close checks, deferral schedules reviewed, cost adjustment verified, bank and credit card reconciliations completed, and in Dynamics 365 Finance the financial period close workspace actually maintained rather than ignored.

2. Dimension and Posting-Group Governance

Who may create dimensions, accounts and posting groups; a documented mapping; and a monthly review that catches miscoded entries while they are still cheap to fix.

3. Bank and Subledger Reconciliation

Statement import and matching supervised rather than trusted, unmatched items worked, and AR, AP, inventory and fixed asset subledgers proved to the GL — see our bank reconciliation services.

4. Intercompany and Multi-Entity Bookkeeping

Intercompany transactions posted through the IC framework rather than ad hoc journals, eliminations prepared and documented at consolidation, and dual-currency postings in Finance kept clean.

5. AR, AP, Payroll Entries and 1099s

Receivables, payables, payroll journals from your payroll provider, and year-end 1099 filing.

The Dynamics 365 Rescue: After Go-Live, and After QuickBooks

The most common engagement is the post-migration cleanup. Microsoft’s own QuickBooks migration tools for Business Central move master records, G/L beginning balances and open documents — and Microsoft documents the limits plainly: only full amounts are migrated, partially paid amounts are not updated, purchase orders and sales orders are not migrated, and beginning balances may need manual correction. The wizard gets you started; it does not hand you clean books. We true up the opening balances, rebuild the open item detail, and reconcile the first months on the new system.

The second pattern is the post-go-live drift: an implementation partner configured the system, left, and a year later the dimensions are inconsistent, cost adjustment has not run, and the bank has not been reconciled since spring. We quantify the damage by period, fix the configuration causes, and put the close calendar in place.

Months behind on either system? Start with catch-up bookkeeping.

Why Outsource Your Dynamics 365 Accounting to Maxim Liberty?

Your implementation partner builds the system; we run the books inside it, month after month. Microsoft supports exactly this split: Business Central licenses include up to three free External Accountant licenses per tenant, with a built-in invite workflow — so bringing us in costs nothing in licensing and touches nothing in your partner relationship.

We have kept US books since 2005, we are BBB A+ accredited, and plans start at $75/month with dedicated bookkeepers at $15/hour for businesses and $10/hour for CPA firms who white-label our team.
