A mobile app for STP engineers: complete the service sheet on any phone, offline, with photos, voice notes and signatures — and hand the customer a branded PDF on the spot.
No app store, no installation project — it runs from a link and works with no signal.
OffMains reproduces real service paperwork field-for-field — the VORTEX 12-monthly service sheet, a generic activated-sludge service, and manufacturer commissioning records — so engineers and warranty teams see the form they already know, just impossible to leave half-finished.
Rural sites rarely have signal. Every record, photo and signature lives on the device and syncs nothing until you say so.
Import your existing customer Excel; re-imports update rather than duplicate. New customers added at the gate.
Two owners, one tank? One visit produces personalised reports for both. Groups of 3+ get a single group report.
Dictate comments, attach captioned photos, capture engineer and customer signatures with a fingertip.
A professional A4 report with your logo, emailed from the driveway or saved to your cloud drive.
Manufacturer installation records with mandatory fields and enforced photo evidence — complete, legible, same-day.
Less than half the cost of generic job-management software — and it actually knows what an SSV30 reading is.
Tank manufacturers and merchants: per-tank bundle licences available — ship a year of OffMains with every unit sold. Talk to us.
Video guides arrive with the training & certification module: manufacturer-approved training on every service task — how to take an SSV30, blower diaphragm changes, commissioning — with short assessments and a per-engineer competency record. Pass, and your company is listed in the public certified-installer directory.
Watch the guides, pass the assessments, hold a dated competency record for every engineer — auditable proof for warranties and grant schemes.
Reports from certified engineers carry the certification mark — visible reassurance for homeowners and scheme operators.
Certified companies appear in the public directory, searchable by area and postcode — certification that wins you work, not just paperwork.
