For instrument, implant and set suppliers

Software for surgical instrument distributors, built around sets that travel.

Aura Business handles a catalogue of thousands of individual instruments, the sets and kits assembled from them, the loan sets that go out to a theatre for a case and come back, and the lot and serial traceability a hospital expects you to produce on request.

Why surgical distribution is an inventory problem first

A surgical instrument distributor carries far more part numbers than almost any other medical trade, and a large share of them are never sold on their own. They are members of a set: a tray of instruments and sizes that goes to a theatre together because the surgeon may need any of them. Software for this business has to model the set as a thing you own, book out, price and chase, while still holding every instrument inside it as a stock item with its own lot or serial.

The second complication is that a set comes back. It goes out on a delivery challan for a case, the used items are billed, and the tray returns to be cleaned and sterilised before it can go anywhere else. Aura Business tracks the set as stock in a location, with a movement out, a consumption record, a return and a turnaround stage, so what you can actually promise a hospital next week is a real number rather than a count of trays on a shelf.

Where it breaks

The tray is out, the paperwork is not.

Most of these businesses run on a catalogue spreadsheet, a challan book and the memory of whoever handles the theatre calls.

Sets counted, not tracked

You know you own six sets. You cannot say where four of them are today or which are fit to send tomorrow.

Items missing on return

A tray comes back short of two sizes and nobody notices until the next case, because nothing checked the set against its contents list.

Used items billed late

The theatre note says what was implanted, the invoice follows a fortnight later, and some of it is never billed at all.

Lot numbers on paper only

A hospital asks which lot went into a particular case, and the answer means searching a challan book.

Catalogue too big to search

Thousands of part numbers, similar names and many sizes, so quoting is slow and the wrong reference is picked.

Turnaround invisible

Sets waiting to be cleaned and sterilised look like available stock, so two theatres are promised the same tray.

How it runs

From the booking call to the invoice for what was used.

01

Book

A theatre requests a set for a date; the request is logged against the hospital account with the surgeon and the case.

→
02

Issue

The set moves out of its location on a delivery challan, scanned item by item against its contents list.

→
03

Use

After the case, the items consumed are recorded against the challan with their lot or serial numbers.

→
04

Bill

A tax invoice is raised for what was used, with the balance returned rather than billed.

→
05

Return and turn around

The tray is received back, checked against its contents, and held in a turnaround location until it is ready to go out again.

→
06

Replenish

Consumed sizes trigger reorder alerts, and a purchase order goes to the principal to make the set whole.

In practice

Four things a set-based business needs to get right.

Two theatres want the same tray

Workflow: The set is shown as issued with a return date, and the second request is offered the next free tray or a date after turnaround.

Result: No promise that cannot be kept.

A tray returns short

Workflow: The return is scanned against the set contents and two sizes are missing, so a short-return note is raised on the hospital account the same day.

Result: The loss is recovered while the case is still remembered.

The invoice follows the case, not the month

Workflow: Consumed items are entered against the challan on return, and the tax invoice is raised from those lines with lot numbers on it.

Result: Nothing used goes unbilled.

A lot is traced in minutes

Workflow: The hospital asks about a specific reference; the item's movement ledger shows the goods receipt, the challan it went out on and the case it was billed against.

Result: A traceable answer instead of a search through challan books.

Questions

Surgical instrument distribution, answered.

Can a set be handled as one item and as its contents at the same time?

Yes. The set is held as stock in a location with a contents list, while each instrument or implant inside it remains a catalogue item with its own serial or lot. Issue and return are scanned against the contents so shortages are visible immediately.

How do you handle stock that sits at a hospital rather than in your warehouse?

Create the hospital-side holding as its own location. Stock moved there stays yours and stays visible, movements are recorded, and consumption at the site is what triggers the invoice.

Can we bill only the items used from a set?

Yes. The consumed lines are recorded against the challan after the case, and the tax invoice is raised from those lines with lot or serial numbers carried onto it. The rest is received back into stock.

Does the system know a tray is not available while it is being cleaned?

Use a turnaround location. A returned set is received into it and only becomes available when it is moved back to the issuable location, so sterilisation time is reflected in what you can promise.

Is the catalogue workable at several thousand references?

Yes. Product lookup, barcode scanning and brand-aware catalogue records are designed for large catalogues, and quotations are built by searching the catalogue rather than typing descriptions.

Can we prove which lot went to which case?

The stock movement ledger holds every step from goods receipt to challan to invoice, and the audit log records who did what. That chain is what you show when a hospital asks about a specific reference.
