I will automate your month end financial reporting with python and excel
Finance data analyst
About this Gig
Still rebuilding the monthly report by hand from accounting exports?
I build a Python and SQL pipeline that turns your CSV or Excel exports (QuickBooks, Xero, NetSuite, Business Central or any other system) into a validated reporting pack in Excel, in one command.
WHAT YOU GET
- Accounts mapped to your reporting lines, in a mapping file you can edit in Excel
- Data checks before any number reaches the report: unbalanced journals, duplicates, unmapped accounts and missing departments, each pointing to the file and line
- P&L and budget vs actual for the month and year to date; multi-entity and multi-currency on Standard and Premium
- A draft variance commentary built from reconciled numbers (Premium)
- Full source code, a run guide and a recorded walkthrough
WHY ME
3+ years building FP&A and controllership data inside finance teams, plus a BSc in Computer Science. I speak finance and code.
Please message me a sample export before ordering so we can confirm the right package.

FAQ
Which accounting systems do you work with?
Any system that exports CSV or Excel: QuickBooks, Xero, NetSuite, Business Central, Sage and others. Direct API connections can be quoted as a custom offer.
Do I need to install anything?
Python, which is free. The run guide covers setup in about 10 minutes. If your team cannot install software, tell me before ordering and we will agree on an option.
Do you need access to our accounting system?
No. I only need exports, never logins.
What happens next month?
You run one command. If you prefer, I can run it and maintain the mapping every month through a custom offer.
Can you handle several entities and currencies?
Yes. Standard and Premium consolidate entities and convert currencies at the rates you choose.
