How to Forecast Inventory for Festive Seasons Singapore F&B

Your Bedok Reservoir zi char stall sells 150 plates of sambal stingray on a normal Saturday. Come Chinese New Year (CNY) eve, that jumps to 450—but last year you ran out of squid by 8pm, turning away a table of 10.[1] Festive seasons like CNY (late Jan/early Feb), Deepavali (Oct/Nov), Hari Raya (Apr/May), and Christmas deliver 2-3x sales spikes for Singapore F&B, yet 30% of operators overstock perishables and waste S$5k-10k per outlet.[1][2]

This tutorial walks you through forecasting inventory using your historical POS sales data, local trends, and simple calculations. No fancy consultants needed—just your last 3 years' numbers and a spreadsheet. Expect to cut wastage 15-20% while covering peak demand.[2]

Step 1: Pull Historical Sales Data from Your POS

Start with what sold last festive season. If you're on Eats365 or Qashier, export daily item sales reports for the 7-10 days around the holiday.[1] Manual ledger? Tally receipts from last CNY.

Filter for festive periods: CNY days 1-3 (usually 2x-4x normal sales), Deepavali week (family catering spikes).[4]
Break down by menu item: Focus top 20% sellers like yu sheng (CNY), mutton rendang (Hari Raya).[2]
Calculate average daily sales: (Total festive sales ÷ festive days). Example: 2,000 prawns sold over 5 Deepavali days = 400/day.

Example calculation: A Jurong Point bubble tea kiosk sold 1,200 cups of teh tarik during Hari Raya 2025 vs 300 normal days. Festive uplift: 4x.[4]

Invoco tip: Export sales by ingredient using recipe costing to see prawn usage across laksa, sambal, and grilled items.

Step 2: Factor in Singapore-Specific Trends

Singapore F&B sees uneven festive boosts: hotels/restaurants report record demand in 2024 Christmas despite retail slowdowns.[6] Hawker stalls in wet markets surge 50-100% for CNY bak kwa lines; CBD cafes flatline.[6]

Check local patterns: NEA hawker data shows 20-30% footfall rise in mature estates like Toa Payoh during Deepavali.[web:NEA hawker stats]
Promotions impact: If you run Oddle QR pre-orders for CNY sets, add 25% buffer.[1]
External shocks: Monsoon (Nov-Dec) cuts outdoor sales 15%; plan indoor catering.[4]

Use Straits Times festive F&B reports for uplift estimates: CNY +150% for family-style zi char.[6]

Step 3: Build Your Forecast with PAR Levels

PAR (Periodic Automatic Replenishment) is your safety net: minimum stock to cover peak day + lead time.[2] Most budget POS like Loyverse lack it; Lightspeed has basic alerts.[3]

Formula: Forecast daily usage × festive days × (1 + buffer %) + lead time stock.

Daily usage = Normal daily sales × festive uplift (e.g., 100 prawns/day × 3x = 300).
Buffer: 20% for no-shows or spoilage (perishables like ikan bilis).[3]
Lead time: 2 days for wet market suppliers.

Spreadsheet example (CNY prawns for 10-table zi char): | Item | Normal Daily | Uplift | Festive Daily | Days (1-7) | Total | Buffer 20% | PAR | |------|--------------|--------|---------------|-------------|--------|------------|-----| | Prawns (kg) | 20 | 3x | 60 | 7 | 420 | 84 | 504 |

Total cost: 504kg × S$25/kg = S$12,600. Last year you bought S$10k and wasted S$2k—now covered.[1]

Adjust for 2026: Enterprise Singapore notes 5% ingredient inflation; scale up.[enterprisesg]

Step 4: Set Reorder Alerts and Supplier Comms

Input PAR into inventory software. When stock hits 30% PAR, auto-alert.[2] For manual: Weekly counts pre-festive.

Supplier sync: Share forecast 4 weeks ahead. Chinatown wet market uncles hold stock if you commit.[3]
Cycle counts: Daily during festive—FIFO (first in, first out) for prawns, tauhu.[3]

Qashier does alerts but manual entry; Klikit ties to sales but no weighted costing.[1]

Step 5: Track Variance and Refine Post-Festive

Post-CNY, run "beginning + purchased - ending" report. Target food cost <32%.[1] Over-usage on sambal? Tweak portions.
