Picture this: you're eyeing a bustling restaurant that claims €50,000 monthly revenue, but the bank statements tell a different story. Sales verification isn't just paperwork—it's your shield against costly mistakes. Smart buyers know that sellers often cherry-pick their best months while hiding the lean periods.
Why sales figures matter more than you think
Revenue drives your entire valuation model. Sellers routinely present their strongest months or massage numbers to inflate worth. You need the real figures to avoid overpaying by thousands.
⚠️ Heads up:
Sellers love showcasing peak months only. Demand complete 3-year records, including the slowest quarters.
Essential documents for verification
Reliable validation requires multiple sources that cross-reference each other:
- VAT returns: Government-reported figures with legal weight
- Monthly revenue breakdowns: Three years of detailed patterns
- Daily register reports: Granular sales data from key periods
- Bank statements: Real money movement
- Financial statements: Complete P&L documentation
VAT returns: your verification anchor
These documents represent your most trustworthy source. They're filed with tax authorities and carry legal consequences if falsified.
? Example calculation:
VAT filing shows €87,000 quarterly revenue including tax:
- Per quarter: €87,000
- Monthly average: €29,000
- Yearly total: €348,000
Remember: food carries 9% VAT, alcohol 21%.
Spotting seasonal fluctuations
Restaurant revenue swings dramatically with seasons. Summer months can exceed winter by 40% or more. Examine 36 months minimum to identify true patterns—a pattern we see repeatedly in restaurant financials shows that buyers who skip this step consistently overpay.
? Typical bistro seasonal flow:
- Jan-Feb: €25,000/month (winter slump)
- Mar-May: €35,000/month (spring recovery)
- Jun-Aug: €45,000/month (summer peak)
- Sep-Nov: €30,000/month (autumn drop)
- December: €40,000/month (holiday boost)
True average: €35,000 monthly
Cross-checking register data
Daily register reports offer granular detail but can be manipulated more easily than VAT filings. Use them for pattern analysis, not primary validation.
- Weekend concentration: Friday-Saturday typically generate 40-60% of weekly sales
- Check averages: Should remain stable across comparable periods
- Cover counts: Must align logically with reported revenue
⚠️ Heads up:
Register totals significantly exceeding VAT returns often signal unreported cash sales. That's acquisition risk territory.
Banking records tell the truth
Bank statements reveal actual cash movement. Compare these against claimed revenues to spot inconsistencies.
- Card payments: Modern restaurants process 70-80% electronically
- Cash deposits: Should mirror register cash sales
- Deposit timing: Look for consistent, logical patterns
Warning signs of dodgy numbers
These indicators suggest unreliable or manipulated figures:
- Cherry-picked months: Missing complete annual data
- Source mismatches: Register vs. VAT return discrepancies
- Convenient gaps: "Lost" records from weak periods
- Spreadsheet-only data: No official documentation
- Banking secrecy: Refusing statement access
? Real-world validation:
Seller claims €40,000 monthly:
- VAT returns: €35,000/month
- Bank deposits: €33,000/month
- Register reports: €40,000/month
Reality check: Actual revenue sits at €33,000-35,000
Beyond raw revenue numbers
High sales don't guarantee a profitable acquisition. Examine these factors too:
- Net margins: Restaurant industry standard ranges 5-15%
- Fixed costs: Rent, labor, and supply expenses
- Revenue trajectory: Three-year growth or decline patterns
- Management dependency: Can it operate without current ownership?

How do you verify sales figures? (step by step)
Gather all financial documents
Ask for VAT returns from 3 years, monthly revenue summaries, cash register reports from representative weeks, and bank statements. Don't accept "missing" months or Excel files only.
Compare VAT return with other sources
Calculate the VAT return back to monthly revenue and compare with cash register reports and bank statements. Differences larger than 10% are suspicious and require explanation.
Analyze seasonal patterns and trends
Plot 36 months of revenue in a chart to see seasonal patterns and trends. A declining trend over 2+ years is a red flag for valuation.
Validate with operational figures
Check if revenue makes sense: number of seats × average occupancy × average check × operating days. If this deviates significantly from reported revenue, investigate further.
Have an accountant verify the figures
A due diligence by an accountant costs €2,000-5,000 but prevents costly mistakes in the acquisition. They can uncover hidden liabilities and irregularities.
✨ Pro tip
Request complete records from the restaurant's worst-performing 12-month period within the past 4 years. Sellers who can't or won't provide these figures are hiding fundamental problems with their business model.
