- Bar & Café Ingredients Vietnam 2026: Yield, Waste & Cost Engineering — Operator playbook for sourcing, yield % and shrinkage on the 40 ingredients that move 80% of a Vietnamese café or bar's COGS. With supplier benchmarks, recipe yield tables and POS deduction workflows.
- GRN automation — closing the supplier-invoice loop — Goods arrive, someone signs the delivery note, the invoice arrives 3–7 days later, finance tries to match them by hand. This is where 4–7% of supplier overcharges hide. GRN automation closes that loop in real time.
- Cycle count vs full stock-take — frequency and accuracy trade-off — Full stock-takes are accurate but disruptive. Cycle counts are continuous but easy to fudge. The right answer for a multi-outlet chain is both, on different cadences.
- Inventory forecasting at outlet vs commissary level — Forecasting at the outlet level catches local demand; forecasting at the commissary level catches production economics. A chain with a CK needs both, and they must reconcile — otherwise CK overproduces and outlets stock out at the same time.
- Waste tracking by station — what gets measured gets cut — Aggregate waste numbers ('3.2% of food cost') do not change anyone's behaviour. Per-station numbers ('the prep station threw away VND 1.8M last week') do. Here is the format that works.
- Cold-chain monitoring for SEA F&B — IoT vendors and cost — Cold-chain breach is the most expensive food-safety failure in F&B — a single freezer fail can write off VND 30M of stock. IoT sensors cost VND 800k each. The economics are not subtle.
- Ingredient substitution rules during shortages — how to keep COGS flat — Supplier missed a delivery. Chef substitutes premium beef for the standard cut. COGS jumps 4 points. Multiply across 30 outlets and a typhoon week, and you have wiped out a quarter's margin. Pre-approved substitution rules prevent this.
- Daily stock-take in 20 minutes — the 'fast count' method — Most outlets stopped doing daily stock-takes because the old method took 90 minutes and nobody had time. The fast count takes 20 minutes and catches 80% of what the long one did.
- FIFO enforcement in cloud kitchens — practical SOP — FIFO is the easiest food-cost win in any kitchen. It is also the one that quietly breaks down within 60 days of any new SOP without enforcement. Here is the SOP that survives a year.
- Supplier scorecard template — 9 metrics that matter — Supplier reviews based on price-per-kg miss everything that actually costs you money — late deliveries, quality variance, short shipments. This scorecard fixes that.
- Yield management for prep-heavy kitchens (banh mi, pho, ramen) — A whole brisket weighs 4.8kg raw. After trim, slow-cook and slicing, it yields 3.1kg of usable phở topping. The 35% loss is not waste — it is recipe yield. If you cost recipes off raw weight, your food cost is wrong.
- Central kitchen for SEA chains — when, why, build cost — Central kitchens cut food cost and stabilise quality. They also add VND 30–60M of monthly overhead. Build too early and overhead crushes you. Build too late and growth stalls.
- Recipe-level inventory deduction — why ±2% beats ±8% variance — Item-level inventory ('we sold 38 phở, we have ingredients for 100') leaves a ±8% variance band — that is your food cost margin. Recipe-level ('we sold 38 phở, that should have consumed 28kg noodle, 3.8kg beef, 14L stock') tightens it to ±2%.
