Pick and Pack Fulfilment for Healthcare Products: How It Works

A pharmacy orders four packs. A hospital orders a pallet. A clinical site orders two chilled cartons that must arrive before nine tomorrow morning. All three hit the same warehouse, the same stock and the same team, and all three must leave with a complete batch and expiry record attached.

That is the difference between general pick and pack fulfilment and pick and pack fulfilment for healthcare products. The physical motions look similar. The control layer around them does not. Every line picked must be traceable to a batch, every batch in date and released, every customer qualified to receive what they ordered, and the whole sequence must survive an MHRA inspection two years later on the records alone.

From order to despatch: the process end to end

Order receipt and integration

Orders arrive by EDI, by API from the customer's ERP or e-commerce platform, through a web portal, or by email for exception handling. EDI remains the backbone for wholesaler and hospital trade because it carries structured line data and acknowledgements. Whatever the channel, the integration must be validated and failed messages visible rather than silent.

Order validation and customer qualification

Under GDP, a wholesale dealer may only supply customers entitled to receive the product. Before an order is released to pick, the receiving pharmacy, hospital or clinic is verified as holding the appropriate authorisation and the product checked against what that customer may buy. Validation also catches operational traps: quantity outside pack multiples, or a chilled line booked on an ambient service.

Allocation, FEFO and batch selection

Allocation decides which stock fills the line. Healthcare fulfilment runs on FEFO, first expired first out, rather than FIFO, subject to any minimum residual shelf life the contract specifies. A hospital may require six months remaining at delivery; a wholesaler twelve.

Some customers require single-batch delivery per line so their own records stay clean; others accept split batches provided each is declared.

Picking methods

The order profile drives the method:

• Piece pick for individual packs, typical of small pharmacy and direct-to-patient orders.
• Case pick for full outer cases to wholesalers and hospital stores.
• Pallet pick for full-pallet movements, the fastest and lowest risk per unit.
• Batch and wave picking, where many small orders are picked together and sorted downstream. This cuts travel but adds a sortation step that must itself be verified.
• Zone picking, where an order is picked in parallel across ambient, chilled and controlled drug areas, then consolidated. On a site like Central Pharma's Bedford warehouse, with more than 10,000 pallet locations, this is often unavoidable.

Scanning and verification

Each pick is scanned. The operator confirms location, product code, batch and expiry, and quantity, and the system rejects a mismatch rather than warning about it. Verification at pack-out is a second, independent check of order against contents before the container is closed.

Packing, cold chain pack-out and documentation

Board grade, void fill and pallet pattern follow from the product rather than what is nearest to hand. Cold chain pack-out is a qualified operation. Shipper, coolant configuration, conditioning time and permitted ambient window are set by a validated pack-out procedure for a stated duration and season, and the pack is assembled to that procedure with the data logger placed as specified. Chilled product is packed against the clock, so pack-out time is recorded, not estimated.

Documentation closes the pick. A GDP-compliant despatch note records date, product name and pharmaceutical form, quantity, batch numbers and expiry dates, supplier and consignee details, and any storage or transport conditions. Retained and retrievable, that record is what makes a recall executable.

Carrier selection, booking and proof of delivery

Carrier choice follows the service requirement: temperature control, security for controlled drugs, delivery window, signature, and whether the route needs a validated transport lane. Proof of delivery is captured and matched back to the order. Unreconciled proof of delivery is a common weak point, and exactly what an investigation needs when a consignment goes astray. Central Pharma runs distribution on in-house electric vehicles alongside approved transport vendors.

The healthcare layer general fulfilment does not have

Batch and expiry on every line. Not just on the invoice, but on the picking record, despatch note and archive, so any unit can be traced from patient back to batch.

Controlled drug picking controls. These scale with the schedule rather than applying uniformly across Schedule 1 to 5. Schedule 1, Schedule 2 and the Schedule 3 drugs specified in the Misuse of Drugs (Safe Custody) Regulations 1973 are picked from a store meeting the safe custody standard, with access limited to named staff. Schedule 4 and Schedule 5 are not subject to that requirement. Controlled drugs register entries at the point of issue apply to Schedule 1 and Schedule 2, with witnessing where the procedure requires it, while Schedule 3 and Schedule 5 transactions are evidenced by retained invoices. Register balances are reconciled against physical stock, not against the warehouse system.

Temperature integrity through the pick. Time out of refrigeration is controlled and recorded, mapped staging areas are used, and excursions during picking are treated as deviations.

Quarantine and hold rules. Unreleased, returned, damaged and recalled stock sits in defined statuses that allocation cannot reach.

Serialisation data where applicable. EU FMD safety features ceased to apply in Great Britain from 1 January 2021 and in Northern Ireland from 1 January 2025, so there is no mandatory UK domestic scheme and serialisation is an export requirement. EU and US consignments still need serial and aggregation data handled; DSCSA has required interoperable EPCIS exchange since 28 May 2026.

Recall traceability. From a batch number, the system must return every customer, order and delivery date in minutes.

Returns

Returns are a licensed activity, not a customer service gesture. Returned product may only go back to saleable stock where storage conditions can be evidenced for the whole time it was away, the pack is intact, remaining shelf life is acceptable and the return is assessed by a competent person. Anything else is quarantined for destruction. Cold chain returns are hardest: absence of temperature evidence is itself a failure.

Measuring performance, cut-offs and peaks

Three metrics carry most of the weight. Line accuracy, correct lines against total lines picked, is the honest version of order accuracy. On-time despatch against published cut-offs shows whether the operation is running to plan. Stock record accuracy from cycle counting predicts short picks before customers find them.

An earlier cut-off for cold chain than for ambient is normal, because pack-out and collection take longer. Peaks, whether flu season, a tender award or a competitor supply failure, are planned with pre-picked stock and booked carrier capacity.

Key takeaways

• Healthcare pick and pack fulfilment differs from general fulfilment in its control layer: batch, expiry, customer qualification and audit trail on every line.
• FEFO allocation with a contractual minimum residual shelf life, not FIFO, is the correct default for medicines.
• Picking method follows order profile, and zone picking is usually needed where ambient, chilled and secure areas must be combined.
• Cold chain pack-out must follow a qualified procedure for a stated duration, with the data logger placed as specified.
• Returns to saleable stock need evidenced storage conditions for the entire period away, assessed by a competent person.

Talk to Central Pharma about pick and pack fufilment

Central Pharma runs pick and pack fulfilment from a 267,000 sq ft licensed site in Bedford, with more than 10,000 pallet locations, temperature-monitored warehousing across ambient, +2°C to +8°C and −20°C, and Schedule 1 to 5 controlled drug storage and supply under a Home Office licence. Distribution uses in-house electric vehicles and approved vendors, backed by an MHRA WDA(H) and MIA, a dedicated QA team and ISO 9001 and ISO 13485. To discuss a requirement, get in touch.
