Following the school inventory: textbooks, laboratory supplies, athletic equipment, supplies, etc. can be a nightmare to logistics. There is the failure of computers, expiring of software licenses and not every administrator or staff feels at ease with complex systems. What would you do if you could monitor, report, request and audit inventory with the use of mere SMS messages?
This guide will take you through an overview of how SMS-based inventory tracking works, why it is effective in resource-constrained settings and how you can implement a viable solution in less than a week. You do not require any special software, training, high-speed internet- connections, but any mobile phone and a tracker capable of sending SMS.
Keep a central spreadsheet (Google Sheets, Excel or even paper log) containing a list of items and its current stock levels.
Determine uncomplicated inventory action codes. For example:
ISSUE [ItemCode] [Quantity] to capture items issued. RETURN [ItemCode] [Quantity] in the case of returning items. STOCK [ItemCode] to inquire of current count.
Either use an SMS-to-email or SMS-to-spreadsheet gateway tool or a dedicated staff phone can receive messages and update inventory in real time.
Implement low stock, missing returns or unusual transactions alerts-received by SMS or email by the inventory manager.
Choose what you’d like to follow: textbooks, lab supplies, sports kit, IT hardware. List records by distinct Item Codes.
Lightweight version: A template in a Google Sheet with columns that include the following: Item Code, Name, total stock, issued, and available.
Semi-automated: configure an SMS-to-sheet service (such as Twilio + Google Apps Script or a web-based SMS gateway) such that incoming SMS messages will automatically fill in the sheet.
Develop transparent and short SMS templates. For example:
ISSUE BIO101 5 RETURN BIO101 2 STOCK BIO101
Educate train personnel or lab assistants to these commands and the need to use correct messaging.
A formula like: in your spreadsheet you can identify a formula to flag when available stock is below a certain amount, e.g.:
=IF([Available] < [Threshold], "LOW", "")
Connect this with the SMS or email notifications so you will be informed when you need to restock.
Begin small -follow one group of textbooks in a group or a particular lab. Gather messages in several days and ensure that the system is updating properly.
Roll out station-to-station: libraries, laboratories, sport equipment rooms. Periodic training of updates, assigning of accountable staff and sharing of Item Code lists among staff.
Conduct periodic SMS log reconciliation with physical inventory. Troubleshooting Use discrepancies to detect errors in SMS entries or process holes.
Chemistry Lab Tracking
SMS Conversation:
Below 10- automatic alert: ALERT: stocks of CHEM-GOGGles only ([?]10 units). Please replenish.
| Challenge | Solution |
|---|---|
| Wrongly formatted SMS messages | Give example formats, use auto-reply on errors |
| Lost or lost phones | Assign backups or fallback to central desk |
| Slow updating of records | Automate using SMS gateway, or use SMS checker |
| Several issuers of the same item | Insert name of sender to registers; insist on confirmation, twice |
| Stock discrepancy or manual error | Periodic physical inspection; reconcile on weekly basis |
The inventory management of a school does not need a state-of-the-art software or equipment. Through the ease and effectiveness of SMS, you are able to develop an efficient, accessible, and simple inventory tracking system, even when working in sparse resource conducive settings. As a librarian, lab assistant or school administrator, this strategy makes you more visible, in control and accountable, all with the palm of your hand.
