Mastering your restaurant’s purchasing management to boost your profitability
In this article:

Purchasing management represents one of the major challenges for professionals in the hospitality sector. Far more than a simple expenditure line, it's a strategic function that directly impacts your restaurant's profitability and efficiency. Between budgetary control, maintaining culinary excellence and organising supplies, every restaurateur must juggle numerous variables to ensure their business's profitability.

In a sector as competitive as hospitality, where raw materials account for between 28% and 35% of turnover, every pound saved on purchasing translates into direct profit. A methodical approach and appropriate tools can transform this constraint into a genuine competitive advantage.

Why is optimising purchasing management crucial for your restaurant?

In the restaurant industry, raw materials typically represent between 28% and 35% of turnover. This considerable proportion makes purchasing a fundamental lever for improving your business's margin and economic viability.

Effective purchasing management goes well beyond simply placing orders. Rigorous management enables you to:

  • Drastically reduce food waste: In France, it's estimated that on average 10% of products ordered by a restaurant are never used. Better planning limits these direct financial losses.
  • Avoid stock shortages: A shortage during peak service disrupts operations, generates stress for your teams and disappoints your customers.
  • Improve your gross margin: By controlling raw material costs, you have a direct lever for increasing the profitability of each dish sold.
  • Guarantee culinary excellence: The consistent quality of your dishes depends directly on the quality of the ingredients you purchase.
  • Strengthen food safety: Rigorous monitoring ensures product traceability and compliance with hygiene standards.

Restaurants that neglect this aspect often see their expenditure spiral and their reputation deteriorate. The primary objective is to create an efficient system that will optimise every pound invested.

Step 1: analyse your needs and define your supply strategy

All optimisation begins with a precise analysis of your operational needs.

Create detailed technical specifications

For each dish on your menu, creating a kitchen technical specification is a non-negotiable step. This essential tool must include:

  • The precise list of ingredients and their exact quantities
  • The cost price of each portion
  • The preparation steps and time required

These specifications enable you to:

  • Calculate the profitability of each dish with precision
  • Avoid ordering errors that lead to waste
  • Plan your restocking with great accuracy

Evaluate needs according to footfall and seasonality

This analysis must take into account your restaurant's footfall, the seasonality of produce, and the specifics of your culinary menu. Use data from your till software to anticipate demand and adjust your orders.

This methodology allows you to know your daily requirements precisely and avoid errors that generate waste. Using a precise specification document will also facilitate communication with your commercial partners.

Step 2: select and rigorously evaluate your suppliers

Supplier selection shouldn't be based solely on pricing. Your suppliers are genuine strategic partners; their selection is crucial for your business's sustainability.

Essential selection criteria

A complete evaluation must include:

Product excellence: Verify certifications, visit facilities if possible, and test products before committing. The quality of raw materials directly impacts that of your culinary creations.

Partnership reliability: Assess delivery punctuality, responsiveness to problems, and ability to adapt to specific requests. A reliable supplier prevents shortages that disrupt your operations.

Commercial conditions: Negotiation isn't limited to pricing. Also negotiate payment terms, delivery times, and return conditions. A good supplier should allow you to pay according to your cash flow constraints.

Geographic proximity: Prioritising local suppliers offers numerous advantages: reduced transport costs, product freshness, support for the local economy, and the possibility of developing a short supply chain offering.

Diversify and monitor performance

Diversifying supply sources limits shortage risks and enables better commercial condition negotiations. Create an evaluation list comprising delivery times, product quality, and compliance with ordered quantities to identify the most efficient partners.

Step 3: implement a structured ordering and receiving system

A well-defined process is key to avoiding oversights, duplicates and costly errors.

Standardise order processing

Establishing a structured ordering process prevents oversights and duplicates. Use standardised order forms that should clearly display product names, quantities and unit price excluding VAT. Establish a regular delivery schedule with your main partners.

Reception control: a critical stage

Systematic inspection of goods upon arrival is a regulatory requirement and an economic necessity. With each delivery, systematically check the conformity of delivered products:

  • Quantities and compliance with the order form
  • Product quality (appearance, freshness, integrity)
  • Crucial information (expiry dates, temperature)

This critical phase enables rapid identification of malfunctions and preservation of your preparations' excellence. Daily monitoring is essential for maintaining a consistent quality level.

Step 4: optimise real-time stock management

Rigorous stock management relies on permanent monitoring and regular information updates. Good stock management allows you to find the right balance: avoiding losses whilst never running out of products.

Establish regular inventories

Organise weekly counts for perishable produce and monthly counts for dry goods. This regularity enables rapid detection of discrepancies between theoretical and actual stock, and identification of waste sources.

Using barcodes and scanners facilitates this task and limits input errors. Some restaurants even use RFID tags to completely automate the process.

Apply the FIFO method (First In, First Out)

Establish a stock rotation system to prioritise using the oldest products. Precise monitoring of expiry dates prevents waste and guarantees food safety.

Modern technologies generate automatic alerts for products approaching their expiry date, enabling optimal valorisation or alternative transformation.

Define optimal stock thresholds

Determine minimum and maximum thresholds for each product based on average consumption, supply frequency, and seasonality. This technique prevents both shortages and overstocking.

Step 5: equip yourself with the right technologies to automate and manage

In the digital age, managing purchasing without appropriate tools has become counterproductive. Modern technologies are valuable allies for improving efficiency.

Specialised IT systems

Suitable management software centralises all information relating to your supplies. The solution offered by Inpulse enables tracking of the entire supply chain: from price lists through to product delivery.

Thanks to automated supplier ordering, Inpulse automatically generates the purchase order based on the restaurant's needs and the supplier's logistical conditions. Orders are sent directly via the software by email or EDI connection.

Connected POS systems and complementary solutions

Modern till software analyses commercial data to identify trends, automatically calculate raw material requirements, and trigger alerts in case of low stock. Inpulse is now integrated with over 70 POS systems, enabling automation of theoretical stock levels in real time.

Complementary tools also automate invoice processing, from receipt to payment, by checking document conformity and identifying duplicates.

Mastering costs and improving profitability

Cost price analysis

Precisely calculate the cost of each culinary creation by incorporating raw material pricing, as well as labour costs and fixed charges. Regularly update these calculations based on changes in partner pricing.

Optimised commercial negotiations

Negotiations aren't limited to pricing. Also negotiate payment terms, volume discounts, additional services, and quality guarantees. A win-win relationship improves services and can lead to preferential conditions.

Food waste reduction

Identify waste sources: overproduction, poor storage, unsuitable portions, or defective stock rotation. Every pound saved on waste directly impacts your profits.

Performance indicator monitoring

Establish a dashboard with fundamental indicators: material expenditure/turnover ratio, waste rate, stock turnover times, and profit per creation. With Inpulse, it's possible to centralise this data and facilitate its analysis.
