Custom ERP for distributors and wholesalers

Distribution ERP software built around your pricing and warehouses

Purchasing, stock, pricing, fulfilment and credit in one system that follows how you actually sell.

Wholesalers live on price lists, stock accuracy and landed cost. We build custom ERP for distributors whose rules a packaged product cannot hold without heavy customisation, and we tell you plainly when buying a package is the better choice. Choose 2 to 3 key modules and test them in a free pilot first.

What the system covers

Nine areas where a distributor makes or loses money

Each area is scoped with you. The first two or three become the pilot; the rest follow after you approve it.

Purchasing and landed cost

Reorder suggestions from stock, sales history and supplier lead times, then purchase orders with approvals.

Freight, duty, insurance and handling are spread across the received items, so stock value and margin use the real cost of getting goods onto the shelf rather than the supplier invoice price.

Multi-warehouse stock

Several warehouses, bins and zones in one stock record, with transfers that show an in-transit state.

Putaway and picking rules by zone or route, scanner-driven receiving and picking, cycle counts by class with variance approval, and one view of available-to-promise across locations.

Batch, lot and expiry

Lot numbers and best-before dates captured at receipt, carried through transfers and shown on the pick.

First-expiry-first-out suggestions, quarantine and blocked status, and a recall-style trace from supplier lot to the customers who received it, for lines where dated stock matters.

Price lists and customer contracts

Customer-specific prices, quantity breaks, promotions and contract prices with start and end dates.

A written order of precedence, a margin floor, and approval for overrides. Old contracts expire on their date instead of silently staying live.

Route and van sales

Delivery routes planned by day and area, and van stock tracked as its own location.

Mobile order taking and invoicing on the route, cash and credit collected on the spot, and an end-of-day reconciliation of stock, invoices and cash.

Returns and credit notes

Return authorisation with a reason code, then a decision: restock, scrap or return to supplier.

Credit notes linked to the original invoice and lot, with the stock and ledger effect posted together so returns stop being a month-end clean-up.

Credit control and collections

Credit limits and terms by customer, automatic holds on overdue balances and a release approval.

Statements, collection notes and promised-payment dates in one place, so the order desk and the finance team see the same status.

EDI and e-commerce feeds

Orders from a B2B portal or web store arrive on a schedule, and stock and prices go back out.

EDI with larger customers and suppliers for purchase orders, ship notices and invoices in the formats they require, assessed per partner before we promise anything.

Reporting for owners and managers

Margin by customer, item and sales rep; stock turn and aged stock; fill rate; open orders.

Supplier performance, cash collected against targets, and slow-moving stock with a threshold you set. Reports run on the live data, not an exported spreadsheet.

If you are still weighing the project, our guide to ERP for distribution companies explains the requirements, and distribution ERP implementation steps and a feature checklist covers the project from data cleanup to cutover.

Honest decision guide

Buy a package or build a custom distribution ERP?

Many distributors should buy. This table shows where each option is stronger so you can choose on fit.

A packaged distribution ERP compared with a custom distribution ERP on process fit, speed, pricing rules, integrations, cost model, roadmap control and risk
QuestionPackaged system (such as S2K, SAP Business One or NetSuite)Custom distribution ERP
Your processClose to standard wholesale: buy, stock, sell, ship, invoicePricing, routes, packaging or customer rules that set you apart
Time to a first working systemQuicker when standard features cover the need and the implementer has done it beforeFree pilot of 2 to 3 modules first; the full schedule is set from your requirements

IntegrationsStandard connectors for common platformsBuilt to the exact EDI formats, portals and equipment you use
Cost model over five yearsLicences or subscriptions that grow with users, plus customisation feesMostly the build and support; no per-user licence
Control of the roadmapThe vendor sets itYou set it and own the source code on full payment
Risk if requirements are unclearLower: proven product with known behaviourHigher until a pilot proves the design on your data

Buying a package is usually better when

  • You are a small or mid-sized distributor with standard processes and a team that wants a proven product with a large implementer ecosystem.
  • Your price lists, units of measure and fulfilment are close to what the product ships with, and customisation would be light.
  • You need a vendor-run product with a long upgrade history and are happy to follow its roadmap.

A custom build deserves a comparison when

  • Your price and contract rules, or your route and van-sales model, do not fit a standard price-list structure.
  • Customer-specific EDI formats, portals, labelling or scales make integrations the largest part of the project.
  • Per-user licences are costly for a large order-desk, warehouse and field team.
  • You want to own the code, host where you choose and change the system as the business changes.

The full trade-offs are in our ERP versus custom development comparison, and the build option itself is described on our custom ERP development page. A common middle path is a packaged core for finance with custom pricing, route or warehouse tools around it.

Start small

Three ways distributors choose their free pilot

The pilot is 2 to 3 modules that prove the hardest part of your business on your own data.

Pricing and orders

Customer price lists with contracts, order entry and credit holds

Proves: Proves the rules that cause the most invoice disputes.

Stock and warehouse

Multi-warehouse stock, receiving with landed cost, transfers

Proves: Proves stock accuracy and the true cost of your goods.

Route and van sales

Route planning, van stock, mobile invoicing and end-of-day reconciliation

Proves: Proves field work, including with weak connectivity.

How the work is delivered

Understand, Plan, Select Technology, Pilot, Build and Scale

The same five steps run every project. For a distributor, each step has a specific job.

  1. Step 1

    Understand

    We walk your order desk, warehouse and purchasing flows, including the exceptions: split shipments, price overrides, returns and backorders.

  2. Step 2

    Plan

    Modules, price-rule precedence, warehouses, integrations and reports are written down and the pilot modules are chosen with you.

  3. Step 3

    Select technology

    Architecture follows your users, sites, devices and hosting needs: cloud, local servers or a hybrid that keeps working when the connection drops.

  4. Step 4

    Free pilot

    We build the 2 to 3 key modules as working software on a sample of your own items, customers and prices.

  5. Step 5

    Build and scale

    After you approve the pilot: full development, data migration rehearsals, testing with replayed real orders, training, cutover and support.

Delivery is remote from our Islamabad headquarters, with scheduled video meetings in your working hours. Our hours are Monday to Friday, 9:00 to 18:00 Pakistan time (PKT, UTC+5). For the generic project sequence, see ERP implementation services. The full explanation of the pilot is on how we work.

FAQ

Distribution ERP questions buyers ask

What is distribution ERP software?

Distribution ERP software connects purchasing, inventory, sales, fulfilment, invoicing, credit control and reporting for companies that buy goods and resell them. Its core is stock across several locations, customer-specific pricing and the cost of getting goods to your warehouse. A custom distribution ERP is built around your own pricing, routes, units of measure and integrations.

Should a distributor buy S2K, SAP Business One or NetSuite, or build a custom ERP?

Buy when your process is close to standard wholesale and customisation would be light: a proven product starts quicker and carries less risk. Consider a custom build when pricing rules, route sales, customer-specific EDI or large per-user licence costs are the issue, or when you want to own the code. Run your own orders through each option before deciding. See ERP versus custom development.

Can a custom ERP handle multiple warehouses and bins?

Yes, when it is part of the scope. Stock can be held by warehouse, zone and bin, with transfers that show an in-transit state, scanner-driven receiving and picking, cycle counts and one view of what is available to promise across locations. We confirm the location structure with you during planning.

How does landed cost work in a distribution ERP?

Landed cost adds freight, duty, insurance and handling to the purchase price and spreads them across the received items. The ERP then values stock and calculates margin on the full cost of getting goods into your warehouse, not only the supplier invoice price. The allocation method is agreed per cost type, for example by value, weight or quantity.

Can the system manage batch numbers and expiry dates?

Yes, for the items where they matter. Lots and best-before dates are captured at receipt and carried through transfers, picks and shipments, with first-expiry-first-out suggestions, quarantine status and a trace from supplier lot to customer. Which items are lot-controlled is decided in the planning step.

Can it support route sales and van sales with poor connectivity?

It can. A mobile app takes orders and prints or sends invoices from the van, holds van stock as its own location, and reconciles stock, invoices and cash at the end of the day. Working offline and synchronising later is designed and scoped from your routes and coverage, and is not automatic.

Can you connect it to our EDI partners, web store or B2B portal?

Often, depending on the other side. Each partner or platform needs a workable method (API, file exchange or EDI), the right formats and permission from its owner, so each one is assessed before we promise anything. Tell us the partners, the document types and the volumes and we will say what is feasible.

How are customer price lists and contract prices handled?

Prices are stored by customer, group, item, quantity break and date range. The system applies a written order of precedence, for example contract price first, then customer list, then quantity break, then standard price, with a margin floor and an approval for overrides. Expired contracts stop applying on their end date.

How much does a custom distribution ERP cost?

Timeline Digital does not publish prices for custom software, because every project is custom. The price follows the modules, users, warehouses, integrations, data migration and reporting you need. The price is set in three steps: we analyse your requirements, build a free pilot of 2 to 3 key modules, and after you approve the pilot we agree the scope, milestones and commercial terms in writing. Any change request outside the approved scope is reviewed and agreed with you before extra work begins.

How long does a distribution ERP take to build?

There is no fixed timeframe: the schedule for your distribution ERP is set from your requirements in the Plan step. The free pilot of 2 to 3 key modules is ready in about 2 days, and with 1,200+ developers we have the capacity to deliver a complete system in as little as 2 weeks. A module such as price lists or multi-warehouse stock can be one of the pilot modules you choose. Long-term support under a service level agreement (SLA) follows launch. The full project starts after you approve the pilot, and the scope, milestones and terms are agreed after it.

Can our existing item, customer and price data be migrated?

Usually. Migration is planned after we look at the quality and structure of your data: items and units of measure, customers and ship-to addresses, suppliers, price lists, open orders and opening stock. We rehearse the migration at least twice, reconcile stock and balances after each run, and agree what is carried over before cutover.
