Fergus vs Invven
Two New Zealand field service software options, compared side by side for New Zealand trades.
Which should you choose?
Fergus edges ahead on our New Zealand tiering (Tier S vs A), but both are workable — the right pick depends on your trade, region, and the New Zealand-specific notes below.
Fergus
Tier S · RecommendedNZ-built FSM (Auckland) — founded by an NZ plumber, 20K+ trades businesses NZ+AU
Fergus is the NZ trades-software success story — founded by a working NZ plumber, now 20K+ trades businesses across NZ + AU. Strongest job-costing and profitability features in the NZ/AU market. Native ACC, GST, PAYE handling, deep Xero/MYOB integration.
Pros
- + NZ-built with NZ support timezone
- + Founder is working NZ plumber — domain expertise real
- + Strongest job-costing depth in NZ/AU market
- + Native ACC + GST + PAYE handling
Cons
- − Best fit for businesses serious about job-profitability analysis (steeper learning curve)
- − Pricing higher than entry-tier alternatives
- − Less specialized than Tradify for pure quoting/invoicing workflow
New Zealand note
Founder is a working NZ plumber — product understanding of NZ trades workflow is genuine. ACC (Accident Compensation Corporation) handling native. NZ support timezone.
Invven
Tier A · WorkableNZ-built jobs, invoicing and inventory in one, with cost prices hidden from customer documents
A young Auckland-built alternative to the established NZ stack, pitching the same operator-authenticity argument Fergus already owns. Founded by Shane Smale, who names himself publicly and has owned and operated a New Zealand motorhome dealership for 27 years: adjacent to the building trades rather than of them, which is worth knowing when weighing the domain-expertise claim. Published tiers from NZD $29 to $159 and a self-serve 14-day trial with no card. The real differentiator is inventory-aware invoicing: live stock levels while you build the invoice, and cost price that never reaches a customer-facing document.
Pros
- + Company independently verifiable on the NZ Companies Office register (NZBN 9429053630247), which most vendors this young are not
- + Founder named publicly and verifiably: Shane Smale, on the About page, alongside a registered NZ company number. He added his name within hours of us publishing the anonymity as a con, which is the response we would want from any vendor and the opposite of the usual one
- + Genuine self-serve purchase: sign-up works and the 14-day trial takes no credit card
- + Inventory-aware invoicing is a real differentiator: live stock levels while quoting, and cost price never appears on any customer document
Cons
- − The AI Receptionist is a paid add-on from $39 NZD+GST and is NOT included in the free trial, despite being the headline feature on the homepage and in the vendor's own submission. Verified 2026-08-31.
- − WhatsApp messaging is metered at $0.05 per message on top of the plan price
- − All billing is processed in NZD regardless of the currency displayed, so non-NZ buyers carry the FX conversion and their card issuer's rate. Note the vendor removed the contradictory US-targeting clause from its terms on 2026-09-01 after we raised it, verified the same day.
- − About 5.5 months old (domain registered 2026-03-13), so there is no track record on reliability, pricing stability or support
New Zealand note
INVVEN LIMITED is a registered NZ company (number 9425060, NZBN 9429053630247), confirmed on the Companies Office register 2026-08-31. GST at 15% is added under NZ law. All billing is processed in NZD even where the site displays EUR, GBP, CAD or ZAR, so overseas buyers carry the FX conversion.
