How Much Does Custom Wholesale Distribution Software Cost?

Configuring and integrating a proven ERP, inventory, order, warehouse, commerce, and accounting stack may require 200-600 hours, roughly $10,000-$30,000 at Vertinus's $49.99 hourly rate. A focused custom quoting, ordering, fulfillment, portal, or integration workflow may take 500-1,500 hours, about $25,000-$75,000. A broad custom distribution platform may require 3,000-10,000 hours or more, about $150,000-$500,000.

Most distributors should not replace proven financial, inventory, warehouse, and order infrastructure with a custom platform. Custom development is strongest where a distinctive customer, pricing, product, partner, fulfillment, or exception workflow creates measurable advantage around established systems of record.

Configure or integrate a proven stack: 200-600 hours

This can cover customer and item data, units, price lists, quote and order behavior, purchasing, inventory, warehouse basics, shipping, invoicing, returns, permissions, reports, migration, and one or two supported integrations.

Use native ERP and inventory transactions whenever they accurately represent the operation. Custom screens should not create a second independent order or inventory ledger.

Focused custom distribution workflow: 500-1,500 hours

A first release may include:

• Customers, billing and ship-to accounts, contacts, terms, and stable identifiers.
• Products, units, packs, barcodes, supplier and customer references, and status.
• Customer-specific catalog, price, availability context, and quote or order intake.
• Approved price precedence, quantities, substitutions, and requested dates.
• ERP order creation with line-level accepted, allocated, backordered, and canceled state.
• Warehouse, shipment, tracking, partial, and exception visibility.
• Invoice and payment status from established financial systems.
• Returns, credits, or supplier-recovery references for a supported path.
• Integration failure queues, safe retry, reconciliation, and reports.
• Migration, load testing, operational pilot, documentation, and training.

Broad distribution platform: 3,000-10,000 hours or more

Cost grows with many entities, customers, contracts, products, units, warehouses, suppliers, currencies, pricing rules, credit, quotes, orders, available-to-promise, purchasing, replenishment, warehouse execution, parcel and freight, local delivery, returns, EDI, marketplaces, portals, billing, accounting, analytics, and mobile use.

Credit, tax, trade, export, product safety, regulated goods, customer contracts, accounting, inventory valuation, pricing authority, worker safety, and retention must be supplied by qualified professionals and authorized business leaders.

What changes the estimate

Products, units, and pricing

A small each-only catalog and one price list is simpler than packs, conversions, alternate IDs, substitutions, lots, serials, contracts, quantity breaks, date ranges, freight, customer groups, promotions, several currencies, and precedence rules.

Orders and availability

One in-stock order is narrower than quotes, revisions, credit review, allocations, reservations, backorders, expected supply, partial shipments, substitutes, customer priorities, cancellations, and line-level state.

Purchasing, inventory, and warehouse

Importing on-hand quantity is simpler than demand, forecasts, supplier rules, purchase orders, receipts, units, locations, transfers, counts, adjustments, replenishment, picking, packing, returns, and reconciliation.

Partners and integrations

One ERP connection is narrower than portals, EDI, suppliers, marketplaces, ecommerce, carriers, tax, payments, accounting, data warehouses, several message formats, high volume, and partner-specific exceptions.

Example: customer order portal into ERP

A distributor needs approved customer login, account-specific catalog and pricing, availability context, order entry, substitutions, ERP sales-order creation, line and shipment status, invoice links, and visible integration exceptions.

• Discovery, commercial rules, ownership, data, user research, and prototype: 75-135 hours.
• Customers, users, ship-tos, products, units, catalog, and permissions: 105-210 hours.
• Pricing, availability, cart, order validation, and confirmation: 115-230 hours.
• ERP order, line, allocation, backorder, shipment, and invoice integration: 135-270 hours.
• Exceptions, retry, reconciliation, reports, support, and administration: 100-205 hours.
• Migration, security and load testing, pilot, documentation, and training: 95-180 hours.

Total planning range: 625-1,230 hours, about $31,250-$61,500 at $49.99 per hour, plus ERP, commerce, warehouse, carrier, tax, payment, hosting, and security charges.

How to reduce distribution software cost

• Start with one customer segment, product group, warehouse, and order flow.
• Keep customers, items, orders, inventory, shipments, invoices, and payments in designated systems of record.
• Clean identifiers, units, packs, price rules, and ship-to records before development.
• Use established ERP, WMS, commerce, EDI, carrier, tax, and payment products.
• Handle rare pricing, credit, substitute, freight, and return exceptions manually first.
• Reconcile every order line, shipment, invoice, and integration event.
• Expand only after customers and operations trust the first flow.
