How a Retail Pharmacy Cut Incoming Stock Handling Time 70% With Robotic Dispensing

Manual back-room work collided with counter demand

A privately owned retail pharmacy in São Paulo served walk-in customers, online shoppers, and four subsidiary stores from the same building. Prescriptions still needed pharmacist review, yet technicians also received supplier deliveries, stocked shelves, cleaned boxes, and prepared e-commerce baskets for courier pickup.

Before automation, receiving stock meant scanning invoices and placing each package by hand. Online separation required staff to hunt the aisles while counter queues built. The team was fixed at one pharmacist, one technician, and three inventory employees, so there was little slack when volumes spiked.

• Receiving stock averaged 8 minutes 44 seconds per measured cycle before the robot.
• Separating online orders averaged 5 minutes 45 seconds before automation.
• Quarterly shelf and package cleaning pulled staff away from customer-facing tasks.

A phased robotic dispensing install with unchanged headcount

Researchers ran a prospective pre- and post-implementation time study with an external observer using a stopwatch. Pre-implementation visits occurred in November 2021; the robotic dispensing system went live in January 2022; post-implementation measurements followed in October 2022 across customer service, receiving stock, stocking, separation, invoicing, and packaging workflows.

Incoming packages were measured and barcode-scanned into automated storage while controlled and refrigerated items stayed manual. Staff still verified prescriptions and handed finished orders across the counter. A conveyor link moved stock from upper storage to the sales floor. Layout changes created a cleaner invoicing and packaging zone, which also trimmed interruptions during online fulfillment.

• Map each workflow before changing floor layout or staff roles.
• Route fast-moving packs through automated intake while keeping special categories manual.
• Keep pharmacists on verification and counseling rather than shelf searches.

Measured minutes fell across every workflow

Across 111 observations totaling 22 hours 25 minutes 51 seconds of timed work, total process time dropped in every category. Receiving stock fell 70%, and separation of online orders fell 75%, the largest swings in the study.

Average receiving time moved from 8 minutes 44 seconds to 2 minutes 37 seconds, a 6 minute 7 second saving per cycle. Online separation averaged 5 minutes 45 seconds before implementation and 1 minute 27 seconds after, saving 4 minutes 18 seconds. Stocking averaged 7 minutes 37 seconds before and 3 minutes 56 seconds after, saving 3 minutes 41 seconds.

Customer service, stocking, invoicing, and packaging also posted total time reductions between 36% and 53%. Counter service still needed human conversation, yet average time per customer fell by 34 seconds when retrieval no longer pulled staff into the aisles.

What US operators can take from a Latin American timing study

Service Robot Co. did not run this Brazilian deployment. The published observations are still useful for US retail and outpatient pharmacy leaders weighing pharmacy dispensing robots, because they show where minutes actually leave the building when automation owns intake and storage.

As a vendor-neutral integrator, Service Robot Co. helps US businesses select dispensing automation that fits floor layout and order mix, then handles financing, deployment, training, and nationwide service through one partner. A month to month robot lease or rental path can fund the pilot without betting the full capital budget on day one.

The study kept headcount flat while reclaiming back-room hours. That pattern matches how US teams use robotic dispensing to protect counseling time, shorten medication transport prep for delivery programs, and scale online fulfillment without adding overnight shifts.
