Job-costing software built to your workflow, not a license
We build the iOS app, Android app, and backend behind a construction or field-service job-costing and crew-tracking product — receipts, labor cost, and budget burn in one shared workspace, shaped around how your crews actually work.
Built to your workflow, not rented by the seat
The usual alternative here is an off-the-shelf job-costing SaaS — built for every contractor, not yours, with whatever approval flow and reports the vendor shipped. We build the real thing instead: your fields, your approval flow, your reports, owned outright rather than rented month to month.
A shipped job-costing platform, not a pitch
Kiolfast — iOS, Android, and the backend underneath both — launched in February 2026 and is still running: receipts, crew hours, and budget in one shared workspace the owner and the crew both work inside.
One team, one codebase, one source of truth
The iOS app, the Android app, and the backend API are built and kept in agreement by one team, so a cost calculation can’t drift between what the owner sees and what the crew sees — nothing negotiated between separate app and SaaS vendors.
Built around how the money actually leaks
Receipts left in a glovebox, hours agreed over text, a budget nobody reopens until the job is finished — we design the capture, approval, and reporting flow around your specific process, not a generic one that approximates it.
You own it outright
No per-seat subscription and no vendor roadmap deciding which features you get next. The code, the data, and the infrastructure are yours — self-hosted on Docker, the same setup running applefy.tech itself.
What we deliver
Receipt Capture & Approval
Receipts photographed and uploaded on site, attached to the job automatically, and held in a pending queue so the owner approves what counts against the budget before it moves the total.
Crew Clock-In & Labor Cost
Workers clock in and out in the app; hours are tied to the person and the job, and labor cost recalculates itself — no manual timesheets, nothing that depends on someone remembering a number at the end of the week.
Real-Time Budget-Burn Tracking
Every approved receipt and hour moves against the project budget the moment it lands, with percent-used indicators and a breakdown of spend into labor and materials against what remains.
Cost Reports & Exports
Visual reports on cost, budget, and performance — spend by type, cost compared across jobs — and a full project export when the numbers need to leave the app for an accountant or a client.
Common questions about construction and field-service job-costing software
An off-the-shelf tool is built for every contractor at once, so your approval flow, your fields, and your reports end up bent to fit whatever the vendor shipped — and you’re renting it for as long as you use it. A custom build is shaped around your specific process from the start, and you own the code and the data outright afterward instead of paying a per-seat subscription indefinitely.
No. Job costing and crew tracking — the category Kiolfast is built for — covers the money side: receipt capture, labor hours tied to cost, budget-burn tracking, and cost reporting. Dispatch, scheduling, and work-order management are a different product category. If you need that too, tell us and we’ll scope it as its own explicit piece of work rather than assume it’s already covered.
Yes — Kiolfast, launched in February 2026: a native iOS app, an Android app, and the backend API both run on, all built by us and still running. It’s the proof we point to, not a claim about a broader portfolio of construction-tech work.
The owner creates the project and decides how many people can join; everyone else downloads the app and enters a secure access code. No accounts to provision, no invitations to chase, and no one left working from a disconnected copy of the data.
The same three tiers as any Applefy project: $20K-$40K for a simple build (3-6 weeks), $40K-$100K for a mid-complexity product (2-4 months), and $100K-$250K+ for a complex build (4-8 months). A job-costing and crew-tracking app across iOS, Android, and a backend — receipt capture, labor tracking, and reporting — most often lands in the $40K-$100K range, but we scope the specific case on a call rather than guess.
You do. The repositories, the database, and the deployment configuration are handed over documented and runnable by your own team, with no subscription tying you to us or to a platform vendor.
