Multi-Entity Accounting Consolidation Integration
Let's Connect
Overview
What we built
A business group running 5 legal entities was spending 3 full days every month stitching accounts together by hand in Excel. We connected all 5 Xero organisations and made consolidation automatic.
In plain terms: the group's finances lived in 5 separate Xero organisations, one for each legal entity, and the only way to see the whole picture was to export reports from each and combine them by hand in Excel. That assembly job swallowed 3 full days at every month end, tied the finance team up in copying and checking rather than thinking, and meant the board always received its numbers late. Any slip in the manual inter-company eliminations could ripple quietly through the consolidated figures.
We built a consolidation system that connects to all 5 Xero organisations through their APIs and does the assembly automatically. It identifies inter-company transactions, eliminates them without human intervention, and produces consolidated statements in real time. Month-end consolidation now takes under 2 hours instead of 3 days, elimination errors have fallen to zero, and board reporting lands 8 days earlier each month. The finance team spends its reclaimed time on analysis rather than on assembling spreadsheets.
The Problem
Five entities, manual month end
The group had grown into 5 legal entities, each with its own Xero organisation, its own bookkeeping habits and its own rhythm. Xero served each entity perfectly well on its own; the difficulty began the moment anyone needed a group-level view. No system held a consolidated ledger, so the group picture existed only as a spreadsheet artefact, rebuilt from scratch every single month by the finance team.
The rebuild was entirely manual. Staff exported reports from each of the 5 organisations, pasted them into Excel, aligned accounts across entities and worked through inter-company transactions line by line to identify and eliminate them. The routine consumed 3 full days at every month end, and it demanded the finance team's most careful people precisely because a missed elimination would distort the consolidated result for the whole group.
The consequences travelled upwards. Board reporting could only begin once the Excel consolidation was finished, so directors reviewed figures that were already well into the following month. The finance team, meanwhile, spent its scarce capacity on assembly work rather than on the analysis and forecasting the growing group actually needed from it.
Five disconnected ledgers
Each legal entity ran its own Xero organisation, so no system anywhere held a single, group-wide view of the accounts at any moment.
Manual Excel assembly
Group reports were rebuilt by hand every month: exports from each entity, pasted into Excel, aligned account by account and checked line by line.
Fragile eliminations
Inter-company transactions were identified and eliminated by hand, so a missed or duplicated elimination could flow straight into the consolidated figures unnoticed.
Slow board reporting
Directors could not see group numbers until the 3-day consolidation finished, pushing every board pack deep into the following month.
What it was costing them
Three full working days of finance time vanished into assembly at every month end, and the output still carried manual-elimination risk. Board decisions waited on numbers that arrived late, questions from directors triggered fresh spreadsheet archaeology, and the finance team had little capacity left for forecasting or analysis. The group was paying skilled people to copy data between systems that refused to talk to each other.
The Solution
Real-time automated consolidation system
We designed a custom consolidation system around the group's existing Xero footprint rather than asking anyone to migrate. The system connects to all 5 Xero organisations via API, pulls the entity ledgers continuously and holds them in one consolidated model, so the group view stops being a monthly artefact and becomes a live position that anyone authorised can open at any time.
The heart of the build is automated inter-company handling. The system identifies transactions between the entities, matches them across both sides and applies the eliminations automatically, removing the most error-prone step of the old routine. Consolidated statements are then produced in real time, ready whenever the finance team or the board needs them rather than at the end of a 3-day assembly exercise.
We introduced the system alongside the existing month-end routine rather than switching overnight. The finance team ran both in parallel, verified the automated consolidation against its own Excel workings entity by entity, and only then retired the manual process. That gave the team confidence in the eliminations before anything depended on them, and turned the cutover into a quiet non-event rather than a leap of faith.
Key decisions
Integrate, do not migrate
The 5 Xero organisations stayed exactly as they were: the consolidation system connects over API, so no entity had to change how it keeps its books.
Automate eliminations end to end
Inter-company transaction identification and elimination, the most error-prone manual step, was made fully automatic rather than merely assisted, taking routine judgement calls out of human hands.
Consolidate continuously, not monthly
Statements are produced in real time from live entity data, so the group position is always current instead of being rebuilt once a month.
Prove it before switching
The automated output was verified against the finance team's own workings before the Excel routine was retired, so trust in the numbers came first.
Measurable Impact
What changed after launch
The month-end grind collapsed. Consolidation that once took 3 full days now completes in under 2 hours, and the inter-company eliminations that previously depended on careful manual checking now run automatically, with errors reduced to zero. Board reporting arrives 8 days earlier each month, so directors discuss figures while they are still fresh enough to act on.
The quieter change is in how the finance team spends its time. The capacity that used to disappear into exporting, pasting and reconciling has been redirected to analysis, and the consolidated position is available on demand rather than once a month. Questions that once triggered a spreadsheet hunt can now be answered directly from the live consolidated statements.
