What Is Excel & Power Query
The automation layer you already own
Most UK businesses already have Excel. What most do not have is Power Query — the built-in data transformation engine that turns Excel from a spreadsheet into an automation tool.
⚡
Power Query — data transformation engine
Power Query is built into Excel and transforms raw data exports from any system into structured, clean data for Xero import or management reporting — automatically, without VBA or coding.
🧮
Complex financial models
Excel handles the financial calculations that no cloud tool does natively — commission structures, margin models, scenario planning, capacity calculations, pricing models.
🔄
Bulk Xero invoice import
Power Query transforms data from any operational system — job management software, CRM, timesheet tools, workforce management systems — into Xero's invoice import format automatically.
📊
Management reporting templates
Excel-based management report templates that pull data from Xero via G-Accon or direct export — formatted, consistent, and updated in minutes rather than hours.
📋
Commission and incentive calculations
Complex commission structures — tiered rates, clawback rules, placement confirmations, currency splits — modelled accurately in Excel and automated so the calculation happens without manual input.
🔗
Data bridging between systems
When two systems do not integrate directly, Power Query bridges the gap — transforming the export from one system into the import format for another, automatically.
Why Excel & Power Query
Why Excel and Power Query are still essential for UK SME finance
Every cloud tool has gaps. Excel and Power Query fill them — automating the specific calculations and data transformations that no off-the-shelf software handles for your exact business.
Builtin
Power Query is built into Excel — no additional purchase required
Anysystem
Power Query reads exports from any software that produces CSV, Excel, or XML
Zerocode
No VBA or programming required — Power Query uses a visual transformation interface
5days
Per week of manual invoicing eliminated for one client with a single Power Query automation
Why Excel and Power Query still matter in a cloud-first world: Every cloud tool handles the standard cases. Your business has non-standard cases — a commission structure that is specific to how your business works, a billing calculation that does not fit any software template, a data transformation that sits between two systems that do not connect. Excel and Power Query handle these cases permanently, without ongoing subscription costs, and without requiring your finance function to adapt to how software expects you to work.
What You Can Do With It
What Excel and Power Query can automate in your finance function
The right Excel and Power Query setup eliminates the manual steps that sit outside what your accounting software handles natively.
1
Bulk invoicing automation via Xero import
Power Query takes the data export from your operational system — timesheet software, workforce management, job management, CRM — and transforms it into Xero's invoice import format automatically. Hundreds of invoices are created in Xero in minutes, correctly formatted, correctly coded, and ready for approval.

2
Commission and incentive calculation models
Build a commission model in Excel that takes placement data, applies your exact commission structure — tiered rates, team splits, clawback rules, currency adjustments — and produces the correct commission figure for each consultant automatically. The model runs in seconds regardless of transaction volume.
When your CRM, job management software, or operational system does not integrate directly with Xero, Power Query builds the bridge. The export from System A is transformed automatically into the import format for System B — removing the manual data re-entry step entirely.

Management reporting templates
Excel templates connected to Xero data via export or G-Accon pull live financial data and format it into management reports automatically. Prior period comparisons, budget variances, KPI calculations — all updated by refreshing the data connection.

Financial modelling and scenario planning
Pricing models, capacity planning, acquisition analysis, investment appraisals, break-even analysis — Excel handles the financial modelling that no cloud accounting tool supports. Models built to your specific business logic, not constrained by software templates.
Transform timesheet data, shift records, or workforce management exports into the payroll input format required by your payroll software — automatically. Eliminating the manual re-entry of payroll data removes one of the most common sources of payroll errors.
How Excel and Power Query connect to the rest of the stack
Excel and Power Query work as the data transformation layer between your operational systems and Xero. Here is what those connections look like.
Power Query+Xero
Operational data to Xero invoices automatically
Any operational system that produces a data export can feed Xero invoices via Power Query. The transformation runs in seconds. Hundreds of invoices are imported correctly without manual entry.
→ ['Automated bulk invoicing from any system']
Excel+Fathom
Financial models feeding management reports
Excel handles the complex financial calculations Fathom cannot — custom KPIs, non-standard metrics, business-specific ratios. The outputs feed into management report templates alongside Fathom's automated accounts.
Power Query creates invoices or bills in Xero from operational data. ApprovalMax routes them for approval. The full flow — from source data to approved financial transaction — runs without manual re-entry.
→ ['Automated transaction creation with approval controls']
Excel+Xero
Commission models feeding payroll and invoicing
The Excel commission model calculates accurate figures. Those figures feed directly into Xero as payroll inputs or invoice line items. Commission processing that previously took a day takes minutes.
→ ['Accurate commissions from calculation to payment']

How Fintelwise implements Excel & Power Query
Excel and Power Query automation is one of the highest-ROI interventions Fintelwise delivers — because it uses tools businesses already own and eliminates processes that are genuinely painful.
The most valuable automations are always specific to the business. The Power Query transformation that eliminated 5 days of manual work per week for one client was specific to their workforce management system's export format and Xero's invoice import format. No off-the-shelf tool would have solved that problem.
Fintelwise designs and builds Excel and Power Query automations as part of the Finance Systems Audit process — identifying the specific manual steps that are costing time, designing the automation, and building it to run reliably without ongoing maintenance.
The result is a model or transformation that runs in minutes, requires no ongoing maintenance, and produces the same output every time. The person who previously spent 5 days on the task can now run it in 10 minutes.
Frequently Asked Questions
Excel & Power Query — common questions answered
Power Query is a data transformation and automation tool built into Microsoft Excel. It connects to data sources — CSV files, other spreadsheets, databases, web data — transforms the data using a visual interface, and loads it into Excel in a clean, structured format. It requires no coding or VBA skills.
Yes. Power Query can transform data from any system that produces a CSV or Excel export — timesheet tools, CRM, workforce management software — into Xero's invoice import format. The transformed file is then imported into Xero, creating all invoices in one step. This eliminates manual invoice entry entirely for high-volume billing scenarios.
Yes. Xero handles the standard accounting functions. Excel handles the non-standard calculations specific to your business — commission structures, pricing models, capacity planning, custom KPIs, and data transformations between systems that do not integrate directly. The two tools are complementary.
Excel formulas calculate values within a spreadsheet. Power Query transforms data — reshaping, combining, filtering, and cleaning data from external sources before it enters the spreadsheet. Power Query is used for data preparation and automation; Excel formulas are used for calculations and analysis.
Most individual automations take two to five days to design, build, and test. More complex models — multi-source data transformations, large commission models with clawback rules, multi-entity consolidation models — take one to two weeks. All automations are built as part of the Finance Systems Audit process.
Power Query transformations are documented and maintainable. If the source data format changes — for example, a software update changes the column names in an export — the Power Query steps can be updated to reflect the new format. Fintelwise includes documentation with every automation so your team can maintain it independently.
