Small and medium-sized businesses (SMEs) often outgrow basic spreadsheet templates but cannot justify spending $20,000+ on enterprise BI tools or specialised ERP software. Custom Microsoft Excel automation offers the ideal middle ground: the same architecture a senior finance team would build, owned by the founder, and delivered at a price that pays back in weeks. The six scenarios below are the ones we ship most often for small businesses in the US, UK, and Australia.
The six scenarios small businesses commission most
Across the last 100+ small-business engagements, six scenarios account for about 80% of the work. Each one is a fixed-scope project, ships in one to three weeks, and pays back in under three months. The price ranges are for a senior remote senior consultant; US/UK consultancies charge 3-5x more for the same deliverable.
01
Weekly Cash Flow Forecasting
A custom 13-week cash flow model that pulls bank balances and pending invoices into a dynamic dashboard, enabling founders to predict working capital squeezes months in advance. The single most-asked model in any small business. Built off a single Power Query connection to the bank feed and one SUMIFS by week. Pays for itself the first time it catches a cash squeeze before it happens.
ROI: Working capital squeeze avoidanceFrom $36002
Inventory Reorder and Safety Stock Calculators
Automated reorder point models that evaluate supplier lead times and daily sales velocity to calculate exact purchase order quantities, preventing stock-outs and excess holding costs. Built off the sales register (Power Query) and the supplier master (XLOOKUP). The model is a single tab with a Slicer for category and a formula-driven PO list.
ROI: Stock-out rate down 60-80%From $24003
Multi-Channel Sales and Margin Reporting
Single-click Power Query pipelines that combine Shopify, Amazon, and offline wholesale sales records into one executive gross margin report. The standard pattern is: each channel is a separate query → merge in Power Query → load to the data model → a single Pivot Table with Slicers. Replaces the Friday-afternoon spreadsheet-tidying ritual that consumes every small business owner.
ROI: 5 hours saved per weekStandard build, $180-50004
Project Profitability and WIP Trackers
For service agencies and trade contractors, custom Excel trackers that monitor billable hours against fixed contract budgets to surface unprofitable clients early. The pattern is: hours register + contract register → XLOOKUP for revenue rate per project → margin by project. The WIP tab calculates work-in-progress for accruals. Replaces the gut-feel management of client profitability.
ROI: Margin visibility per clientStandard build, $180-50005
Monthly Board Pack
A one-page monthly board pack that pulls from Xero/QuickBooks and the CRM, presents revenue / gross margin / cash / headcount / runway, and refreshes on a single click. The board gets the same page every month, with the same layout, and the variance is in the comments column. The single biggest unlock for any small business that has a board or an investor.
ROI: Board prep from 4 hours to 30 minutesStandard to Complex, from $18006
Customer Churn and Retention Dashboard
For SaaS small businesses, a customer cohort table that calculates monthly churn, expansion revenue, and net revenue retention. The data comes from Stripe or the billing system; the cohort table is a single SUMIFS pivot. The single most-asked SaaS metric by any investor or board.
ROI: Net revenue retention visible monthlyFrom $360
The four signals that you've found the right consultant
Fixed scope after a discovery call
If the consultant can quote the work in writing within one working day of the discovery call, they have done the work before. Hourly-only billing means the consultant is optimising for invoice size, not outcome.
Three named small-business references
Ask for proof: named references if the consultant has them, or sample builds and a small paid first step if the practice is new. Generic logos with no detail are not proof.
NDA before file review
Any consultant who asks you to send the file before the NDA is signed is not the consultant you want. The right senior will send the NDA template within minutes of the first call.
Documented walkthrough at handover
The handover is a recorded walkthrough, not a meeting. The walkthrough lives in your shared drive. New team members can watch it. The 30-day support window is in the contract.
Excel vs Google Sheets for small business
The Excel vs Google Sheets question comes up on every small-business engagement. The honest answer is that the two tools have different strengths. Excel wins on Power Query, Power Pivot, XLOOKUP, and any file above 100K rows. Google Sheets wins on shared input, simultaneous editing, and zero install. For most small businesses the right answer is Excel for the heavy lifting and Google Sheets for shared input - they integrate cleanly via Office 365 or Google Workspace. The wrong answer is to pick Google Sheets for the entire stack just because it is "free" and lose a week of productivity to performance issues on the first 200K-row dataset.
What the typical engagement looks like
The first engagement for a small business is usually a single scenario from the list above. The kickoff is a 30-minute call, the scope is a one-page document, the price is fixed, the build is two to three weeks, the handover is a recorded walkthrough with 30 days of support. The second engagement is usually the next scenario on the list, often started while the first is still in support. By the third engagement, the small business has a working BI stack on Excel for less than the annual licence of a single Power BI Pro seat.
