Do you waste hours splitting invoices and calculating which part of the pallet belongs to each partner in your purchasing group?
For small businesses, franchises, or local associations, pooling orders is the only way to reach the minimum volumes required by factories and secure wholesale discounts. The bottleneck arises when managing that collective cart. Relying on shared spreadsheets to track who wants ten boxes or who bears the shipping cost generates financial discrepancies, stockouts due to typing errors, and constant fights among partners.
The trap of Traditional Multi-vendor E-commerce
Trying to force platforms like PrestaShop or Magento so that multiple buyers fill a single cart for the same supplier crashes the shipping and payment logic. A standard e-commerce system does not understand logistics cost proration or B2B pallet splitting.
Our solution: Database Engine for Pooled Purchasing
At LANZA ESTUDIO, we develop custom transactional software and relational databases for purchasing centers. We build a platform where your franchisees or partners can aggregate their individual demands in real time until the minimum order is reached, automating all the underlying financial and logistical math.
- Dynamic Proration Calculation: The system automatically divides shipping and customs costs based on the exact weight or volume that each company has contributed to the joint order.
- Minimum Order Quantity (MOQ) Thermometers: We implement real-time indicators so all partners can see how much is missing to close a pallet or container and trigger the shipment.
- Automatic Invoice Splitting: Once the order is confirmed to the wholesale supplier, the database generates and sends exact individual invoices to each participating SME instantly.
- Price Tier Management: The engine automatically recalculates the unit cost downwards for all participants as the global volume of the collective cart increases.
The Real Impact on Your B2B Purchasing Center
- Wholesale margins for SMEs: Allows small businesses to compete with industry giants by accessing factory prices without assuming all the individual financial risk.
- Zero accounting conflicts: Eliminates hours of manual auditing; the software guarantees that each partner pays exactly for the grams or cubic centimeters they consume.
- Order flow automation: Converts a chaotic process of dozens of calls and emails into a silent, scalable, and one hundred percent self-managed operation.
