Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Plate Costs from Invoice Photos for Restaurants

Photo your supplier invoice, get plate costs and delivery-app prices.

At one menu price, DoorDash's 30% cut lifts an owner's 30% food cost to 43%. This tool turns invoice photos into plate costs and app prices.

Delivery pricing is one formula with gated APIs, leaving a crowded invoice-costing tool with no owner pay signal.

In their words

The clipboard pile is the killer. If invoices sit for a week your plate costs are fiction.

Every spreadsheet I've looked at has two entries for the same ingredient, and whichever one the last person to touch the sheet picked is the one quietly driving your plate cost.

I am kinda confused if my costing is right or not. The food cost of a full meal is around 60-65%

The tools that already cover it

  • MarginEdge: Invoice processing, price alerts, recipe analysis; its pricing page mentions no delivery apps; 4.4 times the proposed $79.
  • MarketMan: Starter caps invoice scans at 50 a month; recipe costing included; no delivery-app pricing mentioned.
  • meez: Invoice processing only on the Premium plan; site mentions no delivery-app connection.
  • Cuboh: One-click menu push to delivery apps; no food cost or invoice features found.
  • Deliverect: Menu sync with dynamic pricing; no food cost or margin tools mentioned; enterprise feel.
  • Craftable: AI invoice matching and recipe costing tied to inventory; no delivery-app pricing mentioned; built for groups.
  • GastroMetrics: Indie spreadsheet replacement for chefs seen on Reddit; shows cost control is already given away free.
  • Marginly: Early invoice-first food-cost idea pitched on r/restaurant; same promise as the invoice half of the tool.
  • Claude plus a spreadsheet: One owner snaps invoice photos, units convert to price per gram, 10 to 15 minutes per delivery.

How it was challenged

  • Demand is inflated: of 41 authors, 3 are owners with costing pain, 16 are vendors or builders, 6 look seeded for a QR-menu vendor.
  • Delivery-app demand is one builder's research post; no owner in the data asked for price sync, and the price fix is one formula: price divided by one minus commission.
  • None of the 9 'would pay' posts is about costing or delivery pricing: they cover allergens, calories, meal prep, QR menus, Wix editing and staff chat.
  • Cheap end is crowded: Marginly, GastroMetrics (free tier), CafeTally (a cafe owner's tool with one sale) and a chef's Airtable app surfaced in one month; one owner uses Claude.
  • Photos solve one of four inputs (recipe, portion, price, waste); owners still type recipes, the real onboarding wall; DoorDash and Uber Eats gate auto price push.

The pain point it solves: Disconnected Restaurant Tools

Restaurant operators struggle with disconnected systems for menus, orders, inventory, and scheduling, causing errors and wasted admin time.

Why those fall short

  • order doesn't look like this on the Uber support side
  • QWeb renders only existing fields; no slot, minimum or variant logic
  • estimates still off; charity pickups unreliable; logs don't prevent overproduction
  • owner refuses automation so managers stay in tune with numbers
  • options differ by location and cannot order from multiple places
