Collection Notes

How the data is collected

All data is scraped from public-facing COMMBUYS pages that require no authentication. We use a polite scraper with rate limiting and exponential backoff to avoid overloading government servers.

The discovery script runs daily, querying COMMBUYS for any newly-posted open bids. New bids are scraped in full; known bids are skipped to avoid redundant requests. Open bids are polled multiple times per week to capture any addenda, deadline changes, or new vendor submissions.

Bid attachments (PDFs, Word documents, spreadsheets) are downloaded and stored locally. File download uses the COMMBUYS multi-step form authentication pattern required by the platform.

Data freshness

Bid records are updated each morning. Quote data is refreshed when the polling script detects a change in quote count. The last-updated timestamp on each download reflects when the data was last scraped, not when it changed on COMMBUYS.

Known limitations

  • Pagination not yet implemented — EOHLC has ≤25 open bids (within single-page limit)
  • Quote total values are only available when COMMBUYS discloses them pre-award
  • Award data (final contract decisions) is not yet captured
  • COMMBUYS has no "last modified" timestamp — change detection uses field comparison

Legal & terms

Data is sourced from public government records. COMMBUYS robots.txt permits crawling of all /bso/ paths. We are not affiliated with the Commonwealth of Massachusetts or Periscope Holdings.

About COMMBUYS

Understanding where this data comes from helps you interpret it correctly.

What is COMMBUYS?

COMMBUYS is the Massachusetts statewide eProcurement system operated by the Executive Office for Administration and Finance (ANF). It handles bid solicitations, vendor registration, quote submission, and contract management for state agencies, municipalities, and quasi-public bodies.

Who posts bids?

Any of 1,200+ registered Massachusetts government organizations — from large state agencies to small water districts. State agencies are generally required to use COMMBUYS for procurements above certain dollar thresholds; municipalities participate voluntarily.

Bid types

COMMBUYS hosts Invitations for Bids (IFB), Requests for Proposals (RFP), Requests for Responses (RFR), Requests for Qualifications (RFQ), and informal bids. Each type has different evaluation criteria and legal requirements under Massachusetts procurement law.
