Sigma Computing Consulting for Community and Regional Banks
Give finance and credit back the days spent pulling core banking reports into Excel before every ALCO and board meeting. We build Sigma workbooks on Snowflake that refresh on their own.
The short answer
Where the Hours Go Today
- Board and ALCO packs are assembled from core system exports in Excel.
- Loan and deposit trends by branch or officer take a custom report request.
- Past due and classified loan lists are rebuilt by hand each month.
- Each department keeps its own version of the same balances.
Sigma Workbooks We Build
- Loans and Deposits
- Balances, new production, rates and runoff by product, branch and officer, stored by month so any past date can be reopened.
- Credit Quality
- Past due, nonaccrual, risk ratings and concentrations by segment, with drill paths to each loan.
- Branch and Officer Performance
- Growth, pipeline and profitability by branch and officer, with each user limited to their own book.
- Board and ALCO Pack
- Monthly management and committee reporting built from the same tables, sent on a schedule.
Why Sigma Fits
- Each user sees only their book
- Row-level security by user, team or user attribute lets one workbook serve every branch and officer.
- Data stays in your warehouse
- Sigma queries the warehouse directly with no extracts, so loan-level detail is not copied into spreadsheets on laptops.
- Finance keeps a spreadsheet feel
- The grid works like Excel on live warehouse data, so analysts can check balances and build views without learning SQL.
Data We Connect
- Core banking system
- Loan origination system
- General ledger
- CRM
- Digital banking platform
- Budget spreadsheets
- Snowflake
Common questions
Is Sigma good for bank reporting?
Sigma fits banks whose core and loan data are in, or moving to, a cloud warehouse such as Snowflake and whose finance and credit teams work in spreadsheets. Your security and compliance teams should review the setup for your own requirements.
Can Sigma connect to our core banking system?
Sigma reads from a warehouse, not from the core directly. We load core, loan and ledger data into Snowflake on a schedule, then build the Sigma workbooks on those tables.
Can Sigma produce our call report?
We build management reporting, not regulatory filings. The same tables can support the figures your team reconciles for the call report, but the filing stays with your existing process.
Can each branch see only its own numbers?
Yes. Row-level security limits each user to their own branch, region or officer book, while leadership sees everything in the same workbook.
How long does a Sigma build take?
It depends on your core system, how much history you need and how many reports you start with. We scope it on a short call, starting with one report.
