Service

Warehouse management software development

For warehouse operators, third-party logistics providers and e-commerce fulfilment businesses who need stock locations, goods-in, picking, packing and counting designed around their own racking, order mix and client contracts rather than a generic inventory app that knows what you have but not where it is.

The problem

What goes wrong today

Where it usually starts

A warehouse that has outgrown a spreadsheet knows roughly how many of each item it holds and almost nothing about where.

  • Goods arrive against a purchase order, are counted on the dock and put wherever there is space; the location lives in the head of the person who put them there.
  • When an order for forty lines comes down from the shop at eleven, the picker walks the aisles with a printed list, finds the first eight items, cannot find the ninth because it was put on a high shelf in the wrong aisle, and the packer waits.
  • The item was in stock according to the spreadsheet, so the shop sold it; it will be a back order and an apology.

Where it gets harder

Stock takes close the warehouse for two days and still produce variances nobody can explain, because adjustments made in between were written on a clipboard.

  • Batches with expiry dates are picked oldest-last because the picker takes the nearest box.
  • A 3PL storing goods for six clients bills them from a monthly guess at pallet positions and argues about it.
  • Reorder points exist in someone's memory, so the fast-moving line runs out on a Friday and the slow one has two years of cover.
  • Courier labels are typed from the order into a carrier website, and the tracking number is pasted back by hand, or not.

Scope of the service

What the build covers

A custom warehouse management build normally covers stock from the dock to the courier van:

  • A location model of zones Aisles, bays, levels and bins with barcode labels
  • Goods-in that scans each line against an expected purchase order or client delivery notice, records quantity, batch and expiry, flags shortages and damages, and directs put-away to a suggested bin by product rules such as fast movers near dispatch and heavy items at floor level
  • Order import from one or more shops or client systems
  • Pick lists released singly In batches or as waves grouped by courier cut-off, with a pick path in aisle order
  • Scanning on a phone or hand-held at every pick to confirm bin and item
  • Packing with carton selection and label printing through courier connections
  • Dispatch confirmation back to the shop with tracking numbers
  • Reorder thresholds with alerts
  • Cycle counts by bin or by product that run while the warehouse operates With every variance recorded and approved
  • For third-party storage Client accounts that see their own stock and are billed for pallet positions, handling and picks by your tariff

How discovery works

Discovery works through a goods-in morning and a dispatch afternoon with you: how deliveries are booked and checked, how the racking is actually laid out, which items need batch or expiry control, how many orders and lines leave each day and by which couriers, when the cut-offs fall, who counts and how variances are approved, and what each 3PL client is charged for. Each answer becomes a named stage in the scope document: received, put away, allocated, picked, packed, dispatched, counted, billed.

Deliberately out of scope

  • Purchasing and supplier management, the shop itself, accounting and payroll, each of which stays in its own system and is connected where it earns its place

When the scope grows

Scoping scenario

A 3PL with two sheds, nine thousand bin locations and twelve e-commerce clients wants orders pulled from each client's shop platform, waves released per courier cut-off across all clients, batch and expiry control for two food clients, cycle counts that keep each client's stock accuracy figure visible to them, and monthly billing from pallet-days and handling events. That is a materially different build from a single-shed wholesaler with eight hundred bins and one shop, and the scope document says which is being built.

Deliverables

What you receive

  • Discovery notes from a walk-through of goods-in, a pick wave and a cycle count on your floor
  • A written scope document naming each stock stage, location rule and client charge, with what is out of scope
  • Design of the scanning pages for goods-in, picking and counting, checked on the hand-held or phone your staff will use
  • The build, deployed to your hosting or ours
  • Migration of products, locations, opening stock and open purchase orders from current spreadsheets or systems, where relevant
  • Training for the warehouse manager, goods-in team, pickers and packers, with a one-page guide per scanning page
  • Handover material and full ownership of the source code and your data

Process

How a project runs

Each stage maps onto the project view in your client panel. Durations are set in your proposal, never on this page.

  1. Onboarding

    Access, contacts, product and location lists, a racking plan, sample purchase orders and a look at how orders arrive and leave today.

    Project stage: Onboarding

  2. Planning

    Discovery with the warehouse manager, a goods-in operator and a senior picker; the scope document and milestone plan are agreed.

    Project stage: Planning

  3. Design

    Clickable designs of the goods-in, pick and count scanning pages and the manager dashboard, checked on your hand-helds in the aisles.

    Project stage: Design

  4. Development

    Built in stages: locations and products first, then goods-in and put-away, then orders, picking, packing and courier labels, then counts, thresholds and client billing.

    Project stage: Development

  5. Client review

    Your team runs a goods-in day and a pick wave on real stock in a test zone and tells us where the put-away rules, pick paths or counts do not fit the floor.

    Project stage: Client review

  6. Revisions

    Location rules, pick path order, scan prompts, variance approval and billing lines are adjusted from the review and re-checked against the scope.

    Project stage: Revisions

  7. Ready for launch

    Bins labelled, opening stock counted in, shop and courier connections tested on real orders, hand-helds set up, launch checklist signed off.

    Project stage: Ready for launch

  8. Delivered

    The warehouse runs on the new system; optional maintenance and hosting continue under their own agreement.

    Project stage: Delivered

Integrations

Commonly integrated

Systems this kind of business usually asks us to connect. Each integration is confirmed during discovery; none is assumed.

  • Shop platforms and marketplaces for order import and dispatch confirmation with tracking numbers
  • Courier and carrier APIs for label printing, manifests and tracking
  • Label and thermal printers for bin, product and shipping labels
  • Barcode scanners and hand-held devices, or phone cameras where volumes allow
  • Accounting software for stock valuation, client invoices and purchase order matching
  • Client systems that send delivery notices and receive stock reports

How we would approach it

Worked example

Concept demo

A two-shed 3PL with twelve e-commerce clients

The situation

A third-party logistics business with two sheds and nine thousand bins stored and shipped for twelve online retailers and wanted to stop arguing with clients about stock accuracy and monthly bills.

Why it is a custom build

This needs a custom build rather than a stock app because client ownership runs through every record, the wave logic has to balance courier cut-offs against pick path length, and the billing is derived from operational events rather than entered by hand.

The scope we would propose

  • One location model across both sheds with client ownership on every stock record
  • Orders pulled from each client's shop platform on a schedule
  • Waves released per courier cut-off that group all clients' orders into a single pick path per picker
  • Batch and expiry control for the two food clients with oldest-first allocation
  • Cycle counts scheduled by bin velocity so the fastest bins are counted weekly, with each client seeing their own accuracy figure
  • Month-end billing calculated from pallet-days, receipts, picks and packaging events against each client's tariff

Concept demo: a scoping scenario written to show how we would approach the work. It is not a delivered client project.

Pricing

What affects the price

Every proposal is priced on scope. These are the factors that move it most for this kind of build.

  • Number of sheds, zones and bin locations, and whether locations need relabelling
  • Number of products and whether batch, expiry or serial numbers are tracked
  • Daily order and line volume, and single, batch or wave picking
  • Shop platforms and couriers to connect and how dispatch confirmation flows back
  • Scanning hardware: existing hand-helds, new devices or phone cameras
  • Third-party clients, their portals and how billing is derived
  • Cycle count scheduling and variance approval rules
  • Hosting choice: your own hosting or ours

FAQ

Frequently asked questions

Would the package do, or do we need a custom build?

A single warehouse with bin locations, goods-in against purchase orders, pick lists with scanning, a shop connection and cycle counts is usually covered by the warehouse management package through configuration. Multi-shed operations, waves across many clients, event-based 3PL billing or unusual put-away rules are where the custom route becomes the honest recommendation. Discovery is where we tell you which.

Do we need to buy scanners?

Not necessarily. The scanning pages run in a browser and work with the camera on an ordinary phone, which suits lower volumes. Existing hand-held scanners with a browser can usually be used, and dedicated devices are connected where the volume justifies them.

How does put-away decide where things go?

By rules you set: a preferred zone per product group, fast movers near dispatch, heavy items at floor level, keep like with like, or fill the emptiest bin in a zone. The operator sees a suggested bin and can override it, and the override is recorded.

Can we count stock without closing the warehouse?

Yes. Cycle counts run by bin or by product while picking continues; the count page knows about picks in progress and every variance is recorded with who counted and who approved the adjustment. A full stock take remains possible when you want one.

Who owns the system afterwards?

You do. The source code, product, location, stock movement and client records are handed over at delivery and can be exported at any time. Hosting and maintenance are optional and separately agreed.
