Spreadsheets vs Chemical Program Software: The Real Cost of Manual Tracking
Every chemical program starts in a spreadsheet and most are still there. The spreadsheet is free; the program it hides is not. Here is the comparison, line by line.
Line by line
| Task | Spreadsheets | Chemical program software (Prodesy) |
|---|---|---|
| Field capture | Paper ticket, transcribed at night | Mobile app, offline, synced |
| Actual vs target PPM | Calculated monthly on estimated production, if at all | Daily on allocated production |
| Inventory and run-out | Last read plus a guess | Rolling-average forecast, load board |
| Lab results | PDFs in email; re-typed for reports | Workflow: sample to automated report, trended against treatment |
| Vendor reporting | Seven spreadsheets, seven formats, consolidated by hand | One record, role-based access |
| Telemetry | A separate portal nobody opens | Integrated, any device |
| Executive reporting | Built monthly, stale on delivery | Power BI, live |
| Audit trail | Version 14 FINAL v2 | Every change, who and when |
| Cost | Free, plus ~30 staff-days a month, plus 15–20% variance | Subscription; pricing |
The two hidden costs
Staff time. Chemical coordinators and vendor field staff commonly spend 30 staff-days a month between them consolidating, transcribing and reformatting. That time returns when capture happens once. Variance. Monthly, estimate-based PPM cannot see drift; programs on spreadsheets run 15–20% variance as a matter of course. On any program with more than a few dozen points, the over-treatment half of that variance exceeds the subscription. See the variance guide.
When a spreadsheet is fine
A dozen points, one vendor, one product, no lab program, no telemetry: a spreadsheet works. The moment there are two vendors, a lab program or a production decline to keep up with, it stops working, and the failure is silent. Pine Island is what the transition looks like for a vendor; the Canadian producer is what it looks like for an operator. See chemical management software for what to look for.
Frequently asked questions
Can we import our existing spreadsheets?
Yes. Historical data is normalized into the Prodesy model during onboarding so trends start on day one.
Can our vendors keep using their spreadsheets?
They submit through Prodesy Mobile instead, which is faster than the spreadsheet. Their internal tools are their business.
What does implementation cost in staff time?
About a week of the chemical coordinator’s time over the 30-day onboarding, mostly confirming injection points and targets.
