Fergus has a loyal following among plumbing and trade businesses, reviewers call the job costing genuinely good, and the wish list is specific: no van stock tracking, invoice layouts that can’t be adjusted and waste paper when printed, a parts database short on fields with no photos, no Google Calendar link, and a mobile app that trails the desktop. Fergus publishes an API, which turns each wish into a contained build. Five, pictured.
The van stock tracking reviewers ask for
The gap is verbatim in the reviews. A tracker treats each van as a mini-warehouse: stock in, parts used per job, minimums watched, reorder lists built for Friday, and every part that walks onto a job lands in that job’s costs.
Invoices in your layout, on one page
Margins, spacing, wasted space: the invoice complaints are typographic, and typography is fixable. Documents generated from the Fergus job take your layout, your footer compliance details, and print on one page like they should.
The parts library, with the missing fields
Reviewers want photos on parts and more fields than the database holds. An enriched library gives every part a card, photo, install notes, supplier prices, warranty terms, and keeps Fergus as the system the numbers flow back into.
The calendar link that isn’t there
No Google Calendar connection means the office system and real life double-book each other. A bridge mirrors each crew’s jobs to their own calendar, respects personal blocks, and carries reschedules across in seconds.
The crew view, polished
A companion day view caches jobs, site history, and compliance forms before the truck rolls and syncs when signal allows, so the mobile experience matches the office one.
The common thread
Fergus keeps the job costing crown; the builds fill the edges around it. Each is a contained phase on a short calendar, and trade neighbors Tradify and AroFlo have their own lists.
